Weblogic Managed Server Running BTM Observer Fails to Start if BTM Monitor is Not Accessible (Doc ID 1578507.1)

Last updated on JANUARY 15, 2016

Applies to:

APM - Application Performance Management - Version 12.1.0.3.0 and later
Information in this document applies to any platform.

Symptoms

The following scenario may prevent BTM from successfully starting:

You have a BTM monitor running but not otherwise accessible for some reason.  For example:

Please note that in the above scenario the BTM Monitor process has been started and it is running but it is not responding. Under these circumstances a WebLogic instance running a BTM observer that accesses that monitor may fail to start. 

In other words, a hung BTM monitor will impact a BTM observer and may prevent it from successfully starting.

It is important to note that if the BTM monitor process is NOT running then the observer and the WebLogic instance it is running within will startup OK.  This problem ONLY happens when the BTM monitor is running but in an unresponsive state.

There is a difference in behavior between a NOT running BTM monitor and a BTM Monitor that is running but is NOT RESPONSIVE.
