In addition to introducing support for the new enhanced 3270 user interface, there are some infrastructure considerations you should be aware of with OMEGAMON DB2 V5.11. OMEGAMON DB2 V5.11, in a smiliar fashion to OMEGAMON z/OS and CICS V5.1, introduces support for self describing agents (SDA). SDA support eliminates the need for the application support media when defining the agent to the Tivoli monitoring infrastructure.
Another thing to be aware of is that the OMEGAMON DB2 agent (i.e. the TEMA) has been re-architected in V5.11. Because of this, there are some additional steps you may need to be aware of when deploying OMEGAMON DB2 V5.11. It is important that you review the the documentation in the V5.11 PSP bucket, and look at relevant readme information. Here's a link to the PSP information:
If you overlook this step, you may be missing some relevant information, in particular data sharing related information.
