  Hi Venu,

  Basically there are 3 types of Log files which we require to analyze any Server related issues. All the 3 kind of Log files can be found in “<DOMAIN_HOME>\servers\<SERVER_NAME>\logs” directory (Which is the default location for these files). But in most of the production environments we change the Log File Locations to wherever we want.

  1). Access Logs: These Log files tells us the details of each and every Http Request which is made to the Server. The Byte data/Data/time/request resource/host/client IP addresses…etc.

  2). Server Logs: Tells us about the Activities happening on the Server. This logs are filled up by the WebLogic Server Codes…and somethimes it is also possible that the application also can write inside the WebLogic Server Logs by using “servletContext.log(String)” methos. But that is not a best proctice to allow an Application to write data inside the WebLogic Server Logs. The Server Logs becomes more important when we enable the Debug flags on the Server to deepely analyze different issues…because the debug/info/warning/critical/error…etc messages goes inside the Server Log.

  3). Out Log: This files usually writes the JVM activity and System.out.println(String) data inside it. Whenever we enable some JVM parameters (independent of Server) like -verbose:gc (to get Garbage collection details). kind of flags these Details goes inside the Stdout Logs. Whenever we use “Kill -3 <PID>” or ctrl+break utilities to collect the THREAD DUMPS …it also goes inside the Server out files. We can write the STDOUT and STDERROR messages to any file we want using the following JAVA_OPTIONS:
  -Dweblogic.StdoutDebugEnabled=true
  -Dweblogic.Stdout=”any-stdout-filename” (you can define your File location as well in the file path-name)
  -Dweblogic.Stderr=”any-stderr-filename”

  If you donot want to have a separete Stdout file then you can redirect the Data of your OUT file inside the Server Log using the following Flag:
  -Dweblogic.log.RedirectStdoutToServerLogEnabled=true

  4). NodeManager Logs: These logs provides us the information about NodeManager Activities. NodeManager Debugs also comes in this Log. You can find these Logs inside “<WL_HOME>\common\nodemanager\logs” directory.

  Hi Faisal Khan,

  I am trying to deploy the code in WLS9.2 by using the script. We are using external stage mode, the path is /domain/servers/ser-1/stage/eintel/.ear. I have created directory stage, eintel manually. The script will copy the code to the destination by using ftp. It is showing
  WebLogic/apps/eintel923/eintel923Domain/servers/eintel91/stage/eintel/eintel.ear
  7188056 bytes sent in 0.2 seconds (35868.74 Kbytes/s)
  221-You have transferred 7188056 bytes in 1 files.
  221-Total traffic for this session was 7188630 bytes in 1 transfers
  After copying it will call the script containing weblogic.Deployer. Here I am getting the error as follows and the dirs eintel and the code also getting deleted automatically.

  starting deployment ….
  weblogic.Deployer invoked with options: -adminurl 10.177.107.16:7001 -user weblogic -name eintel -external_stage -source /WebLogic/apps/eintel923/applications/eintel/deploymentSource/eintel.ear -deploy -targets eintel9Cluster

  Hi Guys,
  This issue is environment specific. For this issue I added one cmdline argument
  “-Dcom.mot.corp.GISEnvironment=TEST” and restarted the servers. Again I did the deployment from there everything is working fine.
  Thanks
