JDBC datasource monitoring

"JDBC Monitoring" script, which I was published 2 days back works good for simple single data source and also multi datasources on a domain. But, there is an inadquate information about targeted servers that script doesn't have the flexibility for displaying those managed server mapping with a DataSource.

One of blog follower(Mr. Venkatesh Durai) asked me for the same, A script works for managed server wise display for the Datasource performance monitoring with WLST. It was already discussed by Srikanth Sonti and Vijay Bheemaneni in Oracle WLST ORKUT forums.

Here we go with the latest script, HTH scriptors...

How to run this Script??
Recently one of my blog follower wrote to me " What is the right way for running this monitoring scripts?". Here I am editing my blogs for more readable and flexible for novice WLA.

You need to update with your environment details at line 5, 11, 14. Create this script in a separate folder where you should maintain logs folder, this is expected by line 67.

To run the above script you need to use regular WLST invoking command as follows:
prompt> java weblogic.WLST DSMonitor.py

This is universal way of running WLST I mean on UNIX flavours, on Windows, on Mac OS too.

  1. Hi Pavan, i'm a novice in WLST and trying to understand your py file. I tried various ways but i could not even get my Admin server connected with this DSMonitor.py file.
    I'm getting syntax errors at 'connect' command itself. Am i doing anything wrong ?

    Per your comments i filled all the required credentials where i need to enter my user, paswd and admin URL. Please advise

  2. Dear Novice WLST user,
    You can try any command at your WLST command prompt as a trial. connect() command will makes you to turn from offline to online mode of WLST.
    OSPROMPT> setWLSEnv.sh for UNIX/ setWLSEnv.cmd for Windows
    OSPROMPT> java weblogic.WLST
    After you get WLST prompt you try connect() command assuming user as system, password as weblogic10 and adminurl as t3://localhost:8001 then the command will be given as shown as below
    wls:/offline> connect('system','weblogic10','t3://localhost:8001')

  3. Pavan, my problem is when i'm running the WLST in script mode - in this way

    java weblogic.WLST DSMonitor.py

  4. You need to replace your WebLogic credentials and adminurl in the 10th line. Even this is not helping... send me screen shot of ur window, and your customized script to bhavanishekhar@gmail.com

    1. Hi Bhavani,

      i want WLST to Script check Status on Datasource connections on all the domains - if one of them fails it should send out an email for our team
      Script check Status on Bridges in AQ Domain - if one of them fails it should send out an email for out team
