Oracle makes its MySQL database server and MySQL Client Libraries available under both the GPL and a commercial license. As a result, developers who use or distribute open source applications under the GPL can use the GPL-licensed MySQL software, and OEMs, ISVs and VARs that do not want to combine or distribute the MySQL software with their own commercial software under a GPL license can purchase a commercial license.

Abstract: The objective of the research was to efficiently manage migration process between different Database Management Systems (DBMS) by automating the database migration process. The automation of the database migration process involved database cloning between different platforms, exchange of data between data center and different clients running non-identical DBMS and backing up the database in flexible format, such as eXtensible Markup Language (XML). This approach involved development of a “Database Migration Tool”. The tool was developed on a windows platform using Java Eclipse™ with four non-identical dummy Relational Databases (Microsoft Access, MySQL, SQL Server and Oracle). The tool was run in a controlled environment over the network and databases were successfully migrated from source to targeted destination option specified. The developed tool is more efficient, timely, as well as highly cost effective.


Oracle does not wait for clients to disconnect. Any unfinished transactions are rolled back, and their database connections are terminated.

The incident files and dumps retention policy controls how long generated dump files are kept around. This policy has a default setting of one month (default is 720 which corresponds to 30 days – approximately 1 month).


Note: It is recommended that your client version be of the same release (or higher) as your database version. In addition, to take advantage of Toad for Oracle's new Unicode support, you must be working with Oracle client/server 9i or above.

It seems it also depends on the Client OS, it was more likely that Etc/UTC fails with Ubuntu than RHEL or Windows. I guess this is due to some normalization but I haven't figured out what exactly.


Access to clients' raw data in Oracle and other databases eliminates tedious data entry. Snap has evolved through 10 years of intensive testing and design to a point where it meets most needs.

The Sage 300 ERP (formerly Sage ERP Accpac) open technology concept provides full independence between the functional and technical layers. Sage ERP works can be optimally integrated into web and/or client-server environments and workswith most standard applications: Oracle or Microsoft SQL Server databases, Windows, Unix or Linux operating systems.

The VM will need to be restarted for the additions to be used properly. The next section requires a shutdown so no additional restart is needed at this time.

Oracle JDeveloper is an integrated development environment (IDE) for Java, Java EE, and the Application Development Framework (ADF). JDeveloper supports Java standards-based Web Services, including JAX-WS and JAX-RPC. JDeveloper is also a client for most commonly used relational databases, which include Oracle Database, MySQL database, IBM DB2 database, and SQL Server. In two articles, we shall discuss creating a Java application in JDeveloper.

Though there are several Flashback Database options which are: Timestamp, System Change Number (SCN), Restore Point and Flashback Sequence Number, use of the SCN or restore point is preferred. Begin by obtaining the current database System Change Number (SCN). This will be used on the subsequent step to flashback the database.


Here we review the database upgrade summary sections. We begin by verifying the source and target database details - database name, release, and home. The Pre-Upgrade Checks section lists the issues found and the corresponding actions. The summary includes database parameters' old and changed values as recommended by the pre-upgrade script. Then we click 'Finish' to begin the database upgrade.

Note: Visual Studio Express Editions are not supported with the Oracle Developer Tools. However, ODP.NET is supported with Visual Studio Express Edition.

The tip on Oracle's OTN = Don't type your password in TOAD when you try to connect and let it popup a dialog box for your password. Type the password in there and it will work. Not sure what they've done in TOAD with passwords but that is a workaround. It has to do with case sensitive passwords in 11g.

Since the clone database and Oracle Database 12c are on the same host, another listener (LISTENER2) is configured and started to support the upgraded database. Export the environment variables tns_admin and ld_library_path as shown below.


If you want to use SQL Server Management Studio, you want to install the full Oracle client (https://yamamotonight-m.ru/hack/?patch=7763), not the Instant Client. The full Oracle client is on the same download page as the Oracle database. Assuming that you are installing on a 64-bit version of Windows, I expect you want the "Oracle Database 11g Release 2 Client (https://yamamotonight-m.ru/content/uploads/files/download/112030-patch-set-for-oracle-database-client.zip) (11/2.0/1.0) for Microsoft Windows (x64)" download. This is several hundred MB rather than a couple of MB for the Instant Client.

Depending on the number of components to upgrade, the timeframe varies. An average of 90-120 minutes is common to complete the upgrade for all components.

Application Partitioning: PL/SQL engine is available on both PL/SQL is the language used for both client-side Oracle Forms applications and server-side database triggers and stored procedures, and there is a PL/SQL engine in both Oracle Forms Runform and the Oracle7 Server. This means that you can take advantage of application partitioning to execute application code on either the client or the server. Application partitioning allows you to optimize performance and resource usage by storing and executing procedures either locally or at the server, whichever makes the most sense for your particular application and configuration.

You only need to pay for the client software. Centralized management software is Free of Charge.

Allocate enough memory to the shared and Java pools. This is done by using the Automatic Shared Memory Management (ASMM) or manually.


Following on from the last point, the VMs will each need at least 3G of RAM, preferably 4G if you don't want the VMs to swap like crazy. As you can see, 11gR2 RAC requires much more memory than 11gR1 RAC. Don't assume you will be able to run this on a small PC or laptop.

Oracle recommends that you run the DMU client on the same host as the database server to be migrated to minimize network overhead. If you must run the DMU client on a different host, the minimum hardware requirements are: CPU speed - 2GHz, Memory - 4GB RAM. Avoid having other jobs running in the same environment if they consume significant system resources.


Check the MAC address of each of the available network connections. Don't worry that they are listed as "eth2" and "eth3". These are dynamically created connections because the MAC address of the "eth0" and "eth1" connections is incorrect.

It can connect to a wide variety of databases, including MySQL, Microsoft SQL Server, Oracle, PostgreSQL, and even Firebird. But it is primarily designed for exploring tables. You can examine the table schema (column names and data types), as well as view data. You can enter and execute ad hoc SQL queries and view the results. You cannot, however, graphically manipulate table data - you must issue Insert or Delete statements. The DB Client is not available in the educational or standard editions.


First, install the VirtualBox software. On RHEL and its clones you do this with the following type of command as the root user.

The distributed publish-subscribe messaging framework described here is named as “Bulletin Board”. The Bulletin Board Server 1678 manages Topics 1680, 1682. Bulletin Board Clients can be Publisher/Producer Clients 1670, 1672 or Consumer/Subscriber Clients 1688, 1690. The Publisher/Producer Clients 1670, 1672 publish data or messages 1674, 1676 to Topics 1680, 1682. Consumer/Subscriber Clients 1688, 1690 consume data from the Topics 1680, 1682 sent in messages 1648, 1686. Data pushed to the Topics 1680, 1682 from the Publisher/Producer Clients 1670, 1672 may originate from data sources 1650, which may comprise smart contracts 1652, oracles 1654, logs 1656, sensors 1658, records 1660, databases 1662, streams 1664, and events 1668. Bulletin Board Server 1678 supports a plug-in Message Storage Backend 1692 to store and replay messages. The Message Storage Backend 1692 persists the messages using two options: (1) a Cloud Database or Cloud Storage 1694, (2) Decentralized Storage Platform (such as IPFS or Swarm) 1698 with regular checkpointing of message hashes to a Blockchain 1696. Messages in the Bulletin Board can be either Ephemeral or Persistent. Ephemeral messages are not stored by the Message Storage Backend.

Worked with Enterprise Architecture to produce client Database HA Architecture document utilizing RAC as the foundation for systems requiring 99/9+% availability and other lower available systems being on VM Ware with Data Guard.

Using VirtualBox you can run multiple Virtual Machines (VMs) on a single server, allowing you to run both RAC nodes on a single machine. In addition, it allows you to set up shared virtual disks, overcoming the obstacle of expensive shared storage.

Sometimes basic things like installing the latest Oracle instantclient on the PCs of all of your developers can take considerable time. I typically setup a dedicated DBA Portal website wherever I work and then write up instructions for repetitive things like these.

TOAD for Oracle 11/0 is available for Windows 32-bit platform 2000/XP/2003/Vista/Win7 and for Windows 64-bit platform 2003/XP/Vista/Win7 with 32-bit Oracle Client. For good performance it is enough to have 1 GB RAM whilst for 2 GB workstation it presents platform for very comfortable work. Concerning the disk space, it depends on the choice of your distribution: for example, for Expert edition it will take between 75MB and 100MB. When it comes to supported versions of Oracle databases almost all the versions are supported, from 7/3.4 to the last 11g database. To connect you can use clients for Oracle SQL Net, Net 8 (32-bit only) Net 9, Net 10, Net 11 or Instant Client. Toad version 11/1 will be compiled in 64-bit and will support 64-bit Oracle clients. The projected release for 11/1 is spring 2021.

How It Works You can deploy client-side query result caching to speed up the responses of queries that your database frequently executes in an OCI application. The database keeps the result set data consistent with any database changes, including session changes. You can potentially see a huge performance improvement for repetitive queries because the database retrieves the results from the local OCI client process rather than having to reaccess the server via the network and reexecute the same query there and fetch those results. When an OCI application issues an OCIStmtExecute() or OCIStmtFetch() call, Oracle processes those calls locally on the client, if the query results are already cached in the client query cache. The big advantage of using a client-side query cache is that it conserves your server memory usage and helps you scale up your applications to serve more processes. The client query cache is organized on a per-process basis rather than a per-session basis. Multiple client sessions can share the same cached result sets, all of which can concurrently access the same result sets through multiple threads and multiple statements. The cache automatically invalidates the cached result sets if an OCI process finds significant database changes on the database server. Once a result set is invalidated, the query will be executed again, and a fresh result set is stored in the cache.

A. Tables share a namespace with views, sequences, private synonyms, procedures, functions, packages, materialized views, and user-defined types. Objects sharing a namespace cannot have the same name. For more information, see Chapter 3. 11. A. Column names cannot begin with a digit. They must begin with a letter and can contain letters, numbers, and the characters _, $, or # (underscore, dollar sign, or pound sign). Although a poor practice, PL/SQL keywords, such as EXCEPTION, can be used as a column name. For more information, see Chapter 3. 12. A. The Oracle Advanced Security feature provides additional database security options such as encryption, checksumming, and user authentication via options such as the biometrics. This feature is not necessary to use database profiles. For more information, see Chapter 4. 13. C, D. When you stop a listener, you affect only new client connections and not existing client connections, so C and D are false. For more information, see Chapter 4.


Dedicated Server A dedicated server environment uses a “dedicated” server process for each user process. The benefit of this is that each user process has a dedicated server process to handle all of its database requests. If there are a hundred separate sessions, there will be a hundred dedicated server processes running on the same platform as the database server. The problem is that each dedicated server process is often idle a large percentage of the time. This takes up a lot of operating system resources for server processes that are sitting idle and creates issues when large numbers of users are accessing a system. Oracle databases that allow access from the Internet can have tremendous spikes of activity that generate a large number of dedicated server processes. The dedicated server architecture also does not support FTP, HTTP, or WebDAV clients. Figure 3-3 illustrates the way that dedicated server processes run on the database server platform. A dedicated server process will be run for each user session.

Over the years the Alpha development environment followed the changes in technology. It got LAN support for multiuser, then connectivity to robust SQL databases like Oracle and MySQL. The simple customizations that it had in the old days were upgraded to allow you to add your own code at almost any point, not restricting you to just the many options in their rich property-sheet system. They went from a proprietary desktop client-only to open browser support. Their browser support went from simple to heavy-duty CSS and JavaScript, with simple support for touch on modern browsers. Their path fit with what I had been advocating in my writings here in "The Developer's Challenge in 2021".

Using the Flashback Database quickly brings the database to an earlier point in time by undoing changes that occurred since that time. The advantage of the database Flashback is its fast operation compared to the traditional RMAN restore-recover operations to perform point-time database recovery.

Hitting this button will send the cancel request to the database. The button will activate once something’s running in the worksheet.


Enabling the Flashback Database starts a background process RVWR to write the Flashback logs to the Fast Recovery Area (FRA). The amount of Flashback is set to 129600 minutes (90 days) to target, but not to guarantee enough timeframe to complete the applications' functional testing. The Fast Recovery Area (FRA) size is proportional to the retention target.

While this product is more than capable of backing up a large number of clients with different operating systems, its focus is on protecting the server. This is apparent with the range of their optional database backup options which allow administrators to backup and restore records on the fly with Exchange, SQL, Lotus Notes and Oracle to name a few. Each of these features is a separate module and has to be purchased individually.

The Single Client Access Name (SCAN) should be defined in the DNS or GNS and round-robin between one of 3 addresses, which are on the same subnet as the public and virtual IPs. Prior to 11/2.0/2 it could be defined as a single IP address in the "/etc/hosts" file, which is wrong and will cause the cluster verification to fail, but it allowed you to complete the install without the presence of a DNS. This does not seem to work for 11/2.0/2 onward.


In addition to the basic OS installation, the following packages must be installed whilst logged in as the root user. This includes the 64-bit and 32-bit versions of some packages. The commented out packages are those already installed if you have followed the suggested package selection.

DBD :Oracle installation requires oracle instant client to connect remote database

Jonathan Lewis Jonathan Lewis has been working in the IT industry for nearly 25 years, and has been using the Oracle RDBMS for more than 20. For the last 16 years he has been working as a freelance consultant, often spending only one or two days at a time with any client to address critical performance problems. He also advises on design and implementation problems, and on how to make best use of the most appropriate Oracle features for a given project. Jonathan is renowned throughout the world (having visited 42 countries at last count) for his tutorials and seminars about the Oracle database engine and how to make best use of it. His exceptional ability has earned him an O-1 visa from the United States, allowing him to do consultancy and lecture work there. Jonathan has written two books about Oracle (Practical Oracle8i, Addison-Wesley, 2000; CostBased Oracle Fundamentals, Apress, 2005) as well as contributing to two others (Oracle Insights, Apress, 2004; Oracle Database 10g New Features, McGraw-Hill, 2004). He also writes regularly for the UKOUG magazine, and occasionally for other publications around the world.

The bug with materializing result sets of Oracle procedures with single output cursor is fixed

Since Oracle Database 11g, all traces, incident dumps and packages, the alert log, Health Monitor reports, core dumps, and more files are stored in the ADR, a file-based Automatic Diagnostic Repository for simplified database diagnostic data management. In spite of that new 11g feature, the housekeeping or purging of those files got not considerably simplified. Unfortunately the new Oracle utility ADRCI can not purge all the files that Oracle database generates in ADR. Thus, you should use the other Unix OS methods and tools to accomplish Oracle 11g database housekeeping. In previous posts I described the Unix log rotation mechanism and SYS auditing files purge in adump directory. This time we will talk exactly about ADR purge functionality. But before, let’s look at some basics.

The package name will vary depending on the host distribution you are using. Once complete, VirtualBox is started from the "Applications > System Tools > Oracle VM VirtualBox" menu option.

Customer is hosting their Controller database on an Oracle 11G server. How should they install the Oracle 11G client (https://yamamotonight-m.ru/hack/?patch=1967) on their application server?


There are two recovery options: Use RMAN backup or Database Flashback. Since this is a clone database from an existing backup, select the option 'I have my own backup and restore strategy'. Consider the disk space requirements for +DATA, +FRA, flashback logs, and the archived log file. Disk space requirements must be met before proceeding further, if any.

This enables you to move the database files and Fast Recovery Area (FRA) location. The storage types available are File System and Automatic Storage Management (ASM). For File System, you may select the Oracle Managed File (OMF) option.


All non-incident traces are stored inside the trace subdirectory. This is the main difference compared with previous releases where critical error information is dumped into the corresponding process trace files instead of incident dumps. Incident dumps are placed in files separated from the normal process trace files starting with Oracle Database 11g. We can also check V$DIAG_INFO view lists all important ADR locations including.

With Oracle Database 11g, there is no distinction between foreground and background trace files. Both types of files go into the $ADR_HOME/trace directory.

This procedure provides a bare bones installation to get the RAC working. There is no redundancy in the Grid Infrastructure installation or the ASM installation. To add this, simply create double the amount of shared disks and select the "Normal" redundancy option when it is offered. Of course, this will take more disk space.

The finished system includes the host operating system, two guest operating systems, two sets of Oracle Grid Infrastructure (Clusterware + ASM) and two Database instances all on a single server. As you can imagine, this requires a significant amount of disk space, CPU and memory.


PMON update listener with information about instancesuch as load and dispatcher information. PROCESS parameter determines themaximum load for dedicated connection in database. The interval at which PMONprovides SERVICE_UPDATE information differs according to the workload of theinstance. The maximum interval between these service updates is 10minutes. When the threshold exceeds the limit then listener become “Blocked”and no new session can be made since it refusing incoming connection. Once, listenergets the information from PMON that the thresholds are below the configuredlimit then listener resume accepting connection.

A Net service name allows an Oracle client to use a simple alias to connect to the database server. The alias definition contains all the information needed to create a connection. To create an alias, launch Net Configuration Assistant from Windows Start Menu -> All Programs -> Oracle - <Oracle Home> -> Configuration and Migration Tools. Follow these instructions to create a net service name as a shortcut for the data source value in your connection string.


The information contained in the IP packet header is interrogated to obtain this information. Vendors of this type of firewall include Network Associates and Axent Communications. Proxy-Based Firewalls Proxy-based firewalls prevent information from outside the firewall from flowing directly into the corporate network. The firewall acts as a gatekeeper, inspecting packets and sending only the appropriate information through to the corporate network. This prevents any direct communication between clients outside the firewall and applications inside the firewall. Check Point Software Technologies and Cisco are examples of vendors that market proxy-based firewalls. Oracle works closely with the vendors of both types of firewalls to ensure support of database traffic through these types of mechanism. Oracle supplies the Oracle Net Application Proxy Kit to the firewall vendors. This product can be incorporated into the firewall architecture to allow database packets to pass through the firewall and still maintain a high degree of security.

Wait_timeout=180This software will run on MySQL v5. However, it connects as a v4 client. This means you will have to convert the connection password to the older style. You can do this with a query like the following:SET PASSWORD FOR 'root'@'localhost' = OLD_PASSWORD('magic');See also: NotesDue to certain unusual idiosyncrasies of the different database servers, certain reports will not work correctly with Timesheets Enterprise using different database servers. The Oracle sub folder in the Reports folder contains reports with the special SQL that this database server requires.

In parameter file there was described MEMORY_TARGET parameter to 1500MB but /dev/shm size was not big enough. You should increase the size for /dev/shm (the same as tmpfs).

The first step is to download the Oracle client (https://yamamotonight-m.ru/hack/?patch=2225). This is the actual database software that runs and manages the database.


By finding and implementing recommendations to ensure the database is successfully completed. The DBUA interface shows the progress of the database component and the completion status and simultaneously writes to the log files. DBUA alters and/or creates auxiliary files to support the upgraded database and provision database recoverability in the event of failure and fully supports the database running on Real Application Clusters. For a highly integrated and automated upgrade, the DBUA is available on silent mode from the command-line.

Although Snow’s Inventory has license management abilities and broadly similar features to Express Metrix, its License Manager provides much more sophisticated facilities. Alongside the abilities to monitor software usage, License Manager can also create a license pool, or departmental pools, taking back licenses that aren’t being used so they can be redeployed elsewhere. It goes beyond management of client systems, with the ability to manage Oracle database options and virtual instances on Unix platforms including Sun Solaris, HP-UX and IBM AIX. The support for virtualised environments goes well beyond this, with the suite able to track licenses in App-V, hyper-v, VMWare, Citrix, and Terminal servers. You can manage what individual clients are able to do, and create policies for software with specific functions, without having to name each application individually – blocking all games software, for example.


Add this directory to the PATH environment variable. If you have multiple versions of Oracle libraries installed, make sure the new directory occurs first in the path. Restart any terminal windows or otherwise make sure the new PATH is used by your applications.

When CLUSTER=Y is specified, Data Pump attempts to use all active Oracle RAC instances

PMON is responsible for doing the clean-up there. That’s kind of out-of-scope for this post, but I’m going to say it’s out of the client’s (SQL Developer’s) hands. So let’s get back to the actual query being cancelled.


Connectivity There are many ways in which a client (more tips here) can interact with an Oracle database. A client may be running a PC-based application or a dumb terminal application, or perhaps the client is connecting to the database via the Internet. Let’s take a look at how Oracle (pop over to these guys) supports connectivity to the database through these and other interfaces.

Start the "ol6-112-rac2" virtual machine by clicking the "Start" button on the toolbar. Ignore any network errors during the startup.


Maintain Connections The Oracle Net Foundation Layer establishes and maintains connections with the database server. Transparent Network Substrate (TNS) is the common interface between all the industry-standard protocols. Oracle Protocol Support maps the industry-standard protocols (TCP/IP, TCP/IP with SSL, SDP and Named Pipes) used in the connection. Figure 3-2 shows us how Oracle Net works. Oracle Net software will reside on the database server platform and the platform that is running the Oracle applications. With an application server, HTTP runs on top of a network protocol between the browser platform and the application server platform. Oracle Net then runs on top of a network protocol between the application server and the database server. For a client/server configuration, Oracle Net will reside on the client platform and the database server platform, and will run on top of a network protocol between the client and the database server platforms.

Unzip downloaded file and place OPatch folder in 11/2.0/4 home directory. For this you will need to delete or rename existing OPatch folder.


When Oracle develops a new database release, a parameter may become obsolete or depreciated. Obsolete parameters, underscore parameters and events must be removed prior to starting the database upgrade.

Navicat Premium Serial Key 2021 allows you to drag tables and data from Oracle to MySQL, PostgreSQL to MySQL, Oracle to PostgreSQL, and vice versa within a single client. You can perform various tasks in the database, such as printing reports in MySQL, synchronizing data in PostgreSQL, backing up data in Oracle, and scheduling or automating a job at a specific time. In addition, the new Navicat Premium saves you precious time by managing databases and making database and data migrations at your fingertips.

Oracle Database Client Preinstallation Tasks

Another popular solution is the Sun NFS (Network File System) found on a NAS. It can be used for shared storage but only if you are using a network appliance or something similar. Specifically, you need servers that guarantee direct I/O over NFS, TCP as the transport protocol, and read/write block sizes of 32K. See the Certify page on Oracle Metalink for supported Network Attached Storage (NAS) devices that can be used with Oracle RAC. One of the key drawbacks that has limited the benefits of using NFS and NAS for database storage has been performance degradation and complex configuration requirements. Standard NFS client software (client systems that use the operating system provided NFS driver) is not optimized for Oracle database file I/O access patterns. With the introduction of Oracle 11g, a new feature known as Direct NFS Client integrates the NFS client functionality directly in the Oracle software. Through this integration, Oracle is able to optimize the I/O path between the Oracle software and the NFS server resulting in significant performance gains. Direct NFS Client can simplify, and in many cases automate, the performance optimization of the NFS client configuration for database workloads. To learn more about Direct NFS Client, see the Oracle White Paper entitled " Oracle Database 11g Direct NFS Client".


Btw: I am doing this whole exercise because I want to use ROracle on my R Studio server and this R package depends on the OCI library. Once I am back in R territory the road gets much less bumpier for me.

There are several ways to check the status of the RAC. The srvctl utility shows the current configuration and status of the RAC database.


Because this official page it's all I need to run OCI. To test the whole thing in general I've installed sqplus64, which worked after I set export LD_LIBRARY_PATH=/usr/lib/oracle/11/2/client64/lib. Unfortunately the headers files couldn't be found after setting LD_LIBRARY_PATH. Actually I am not surprised because there is no include directory in any of these oracle paths.

The biggest issue is whether the called window will be a stacked canvas (that has it own window) within the directory application or another form application. If the application is Web-enabled, I recommend that you create stacked canvases enclosed by a window within your initial form. This will cause the download time of the initial Web form to be longer, but will also increase the performance when navigating to the new window. Because it is a stacked canvas that has been downloaded, the user will not have to download the form from the Web. The user will only need to send a database call to Oracle and receive the data. Because it is quite common for a user to view the detail windows for numerous records, this is a good technique to use. Performance is better in a client/server environment.

C. Whenever you receive an ORA-01034, both the database and the instance are not started. For more information, see Chapter 4. 15. C. The database is the parameter supplied after the port designation. Therefore, you connect to the orcl database. For more information, see Chapter 4. 16. D. The LARGE_POOL_SIZE setting is determined by the setting in the Oracle SPFILE. Oracle always reads this file on startup if you are using it. The SCOPE=MEMORY parameter means that only the currently running instance is affected by the change. For more information, see Chapter 5. 17. B. You would set the PRO, DIS, POO, TICK, CONN, and SESS attributes of the DISPATCHERS parameter accordingly. Remember that the TICK measurement is in 10-minute increments. For more information, see Chapter 5. 18. A, B, D. You can see established, refused, and current connections for each dispatcher when you issue this command. You can also see the maximum number of connections allowed per dispatcher and the state of each dispatcher. For more information, see Chapter 5. 19. B. The WAIT status indicates that the dispatcher is waiting to process a client request.
