Looking into Middleware server logs made simple

Middleware Admin means the day runs with Emergency calls or On-calls, supporting team task always under high pressure cooker -- many of them feel tension tension due to heat in the head many got into hair-fall!!! ...

Its a challenging task, only those who can handle the jobs under pressure can do this with tricks. But When you don't have calls you might think to reduce your stress in the work with smart automation scripting to make life more easier.

Best Practices for WebLogic Logs

If the environment is shorter let say it is size of 10 - 20 managed servers, then the best idea is to implement is that all these managed server logs, JMS stores must shared a common mount point. When application support team run into issues, this will give you the flexibility to search the logs easily and faster way to get rid of issues with this unique log location.

In most of your project environments you might find the multiple logs such as application reated, JMS message stores or some transactional logs. In some critical situations, where you might need to look-up for a particular phrase of text in the WebLogic managed server generated logs. If you already follows best practices for collecting logs all together. It is easy to search in the sub sequant sub directories.

#FileName: CheckLogs.sh
#This script is used to find the given pharse in all logs available in the machine

for instance in $INSTANCES
        echo 'Checking for the :' $instance
        cd $INST_HOME/$instance/logs
        egrep -i $phrase c*log*
        egrep -i $phrase c*out

If you keep above script in the general accessible path, such a way that it can be run from any directory on your machine. The Best practices for every WebLogic Middleware server running machines uses JAVA_HOME in their PATH. The best option to store this script is $JAVA_HOME/bin you can run from any path in your user.

Suppose you want to find all the WebLogic Servers which got RUNNING state on a machine. The search pattern you can give as bea-000360.

$ logverify bea-000360
Checking for the : cmgdserver01

Essential Middleware Administration takes in-depth look at the fundamental relationship between Middleware and Operating Environment such as Solaris or Linux, HP-UX. Scope of this blog is associated with beginner or an experienced Middleware Team members, Middleware developer, Middleware Architects, you will be able to apply any of these automation scripts which are takeaways, because they are generalized it is like ready to use. Most of the experimented scripts are implemented in production environments.
