DB2 probe not activating

When installing the db2 probe, even though the software and hardware requirements are met, the probe fails with the following message in the controller.log:

Controller: Max. restarts reached for probe 'db2' (command = db2_monitor) 


  • CA UIM v8.x
  • db2 probe v4.10 DB2
  • Server and Client v9.7
  • The LD_LIBRARY_PATH to where the db2 probe is deployed is added in the controller probe -> Environment tab


The output of the commands './db2_monitor' and 'ldd db2_monitor' ran in the db2 probe directory points towards a missing library:

'./db2_monitor: error while loading shared libraries: libdb2.so.1: cannot open shared object file: No such file or directory'

This library libdb2.so.1 is located away from the other libraries. Therefore, the Environmental variable within the Robot controller needs to point to this location for the probe to activate.

Additional Information

There is an idea opened in communities for this info to be added to the probe guide:


Found this issue with UIM 20.x along with db2 probe 4.x version , same solution set the:

   LD_LIBRARY_PATH in controller probe environment section .

Ran ENV command  to check what is the value of  LD_LIBRARY_PATH on the DB2 probe machine,  and then set the same in the controller probe and then it stated working fine.
