    OBIEE 11g Logs periodic purging

    fiaz0419

      Hi All,

      I want information about how the logs are maintained in OBIEE11g.

      What is the periodic frequency of the logs to be deleted. ?

      Is there any probelm if I  delete log file directly in my server.?

      Does deleting the old logs help me in improving the server performance ? Or is there any other help.

       

      Thanks in Advance.

          if you go into EM you will see the logs will be creating a sequence upto 10 logs and after which it will delete the old(starting from 1) and create a new log from first. You can check the mount space on which you have installed the OBIEE as how much free space is there if any of logs are occupying huge space then you can delete the old ones in that way you have sufficient space for you OBIEE to run well

            Yes, you can delete the files but don't forget to restart the entire application.

             

            In linux if you do not restart the entire application, it will create a tmp files and start writing logs into that, this is bcoz Linux hold the address location and to clear the address location from memory you need to restart the entire application.

              I want information about how the logs are maintained in OBIEE11g.

               

              With OBIEE 10g, most developers knew where to look for the log files which hopefully provided the information necessary to solve a problem.  What about with 11g?  Where are they and how can they be accessed?

              You can check the different log files in the Oracle Business Intelligence (OBIEE).  The right way to check them is using the Enterprise Manager (EM) Console page.

              EM Console. Login to the URL http://server.domain:7001/em and navigate to:
              Farm_bifoundation_domain-> Business Intelligence-> coreapplications-> Dagnostics-> Log Messages

              You will find the available files:

              • Presentation Services Log
              • Server Log
              • Scheduler Log
              • JavaHost Log
              • Cluster Controller Log
              • Action Services Log
              • Security Services Log
              • Administrator Services Log

              However, you can also review them directly on the hard disk.

              The log files for OBIEE components are under <OBIEE_HOME>/instances/instance1/diagnostics/logs.  Specific log files and their location is defined in the following table:

              Log

              Location

              Installation log<OBIEE_HOME>/logs

              What is the periodic frequency of the logs to be deleted. ?

              As aegs mentioned.

               

              Is there any probelm if I  delete log file directly in my server.?

              Nope,But it is not a best practice

               

              Does deleting the old logs help me in improving the server performance ? Or is there any other help.

              Obviously

               

              Mark if helps.

               

              Thanks,
