Stopping an application server

Stopping an application server ends a server process based on the process definition settings in the current application server configuration.

J2CA0020E: Connection Pool Manager could not allocate a Managed Connection: 
java.lang.IllegalStateException: Internal     
Error: cannot find the PoolManager Reference. 

• You can use the Start menu to stop your application server.
  In the administrative console, click Start > Programs > IBM WebSphere > Network Deployment v. n > Stop the server.
  When the server stops successfully, the stopServer.log file contains the following in the last two lines:

  Server stop request issued.  Waiting for stop status.
  Server server1 stop completed.

  The server name varies depending on your settings.

• If a Windows service has been created for the application server, optionally use the Windows Services utility to start, stop, and monitor the basic status of the server.
  1. To launch the Services utility, click Start > Settings Control Panel.

     The Control Panel folder displays.

  2. Double-click the Administrative Tools icon.

     The Administrative tools folder displays.

  3. Double-click the Services icon.

     Read about the Services utility in the Windows online help.

  Read the topic about the WASService command for information about adding and removing Windows services.

• You can issue a stopServer command to stop a single server or the stopManager command to stop the deployment manager.

  Read the stopServer and stopManager topics for information about the commands, including such information as running the commands and defining the log file names.

  Read the topic on using command-line tools for information such as determining from what directory to run the stopServer and stopManager commands.

  You can check that the server or deployment manager has successfully stopped by checking the appropriate log file.

  You should not use the CANCEL appserver_proc_name command to stop a server. Every time a server is started, a new temp directory is created off of the servant process token, such as profile_root/default/temp/node_name/server_name. When the server is cleanly stopped, these temp directories are normally removed. However, if the server is frequently not stopped cleanly, which happens if you cancel rather than stop the server, these temp directories are not removed and the HFS used for these temp directories eventually becomes full. You can also prevent this storage problem from occurring if you precompile your JavaServer pages when you install an application or if you use the JspBatchCompiler function to precompile them before they are invoked.

• You can use the administrative console to stop an application server:
  1. In the administrative console, click Servers > Server Types > WebSphere application servers.
  2. Select the application server that you want stopped and click Stop.
  3. Confirm that you want to stop the application server.
  4. View the Status value and any messages or logs to see whether the application server stops.
• You can use the stopserver Qshell script to stop an application server:
• You can use the End Job (ENDJOB) CL command to stop an application server:
  To use the ENDJOB CL command, enter:

  ENDJOB JOB(jobNumber/QEJBSVR/jobName) OPTION(*CNTRLD) DELAY(delayTime)
  

  where jobNumber is the job number, jobName is the name of the application server job, and delayTime is the amount of time to wait for the job to end in seconds. You can initially set delayTime be 600 seconds and then adjust it, if necessary, to a value that is more appropriate for your environment.
