1. How  to implement CA EEM and LDAP for Authentication and Authorization of CA APM
https://support.ca.com/irj/portal/kbtech?docid=593939
Description:
Using CA EEM, CA Embedded Entitlements Manager, in conjunction with a supported LDAP Server, it is possible to eliminate manual updates to CA APM configuration files every time you need to add a new user, change a password or update access permissions.

CA EEM allows you to utilize a supported LDAP server for authentication while it controls authorization policies for LDAP users and groups. If you do not use LDAP, EEM can even perform authentication duties using the secure, proprietary CA Directory, which is included.

CA EEM is bundled with CA APM and is available from the APM Product Downloads Page on support.ca.com. It can be installed on the same or a separate server as the Enterprise Manager.. CA EEM supports many CA products, serving as a single point of control for authentication and authorization.

12. Example of increased Smartstor Duration due to disk I/O contention related to Transaction Trace activity
https://support.ca.com/irj/portal/kbtech?docid=598102
Description: Enterprise Manager data processing has to complete in under 7.5 seconds otherwise there will be issues with the way data is displayed and stored.

If either or both the Harvest and Smartstor Duration are taking too long, you may start to see gaps in data where the Enterprise Manager delays data processing to keep up.

The whole Harvest and Smartstor process involves the collecting of data from agents and calculators, updating alert statuses, returning query data and then the writing of that data to disk.

The Enterprise Manager waits for the writing of data to be completed before harvesting again. This is why the two are important to each other.

One way that the Smartstor Duration can be affected is if there are other concurrent disk operations, for example writing transaction trace data to disk.

 

13. How can I delete a large number of users or usergroups at one time?
https://support.ca.com/irj/portal/kbtech?docid=594614
Description:
This is the typical way to delete a usergroup from APM CE:

To delete a user group:

Select Administration > User Groups.
On the User Groups tab, select the check box for the user group that you want to delete.
Click Delete.
But the approach only allows deleting 25 users (on one page) at a time. Is there a way to do a batch delete of a large group of users (Such as 275,000)?

 

14. How to fix "unable to execute query" JDBC exceptions when trying to view some CEM web pages which are due to incorrect postgres APM database table ownership.
https://support.ca.com/irj/portal/kbtech?docid=595658
Description:  If ownership of some tables in the postgres APM database (cemdb) is incorrect it can cause this type of error when trying to view data on a CEM web page:
Internal Application Error: JDBC exception on Hibernate data access; nested exception is org.hibernate.exception.SQLGrammarException: could not execute query
Checking the DEBUG MOM log should show the root cause and often this can be permissions related to permissions for a table (relation) e.g.
Caused by: org.postgresql.util.PSQLException: ERROR: permission denied for relation ts_defect_meta_values_20130218

NOTE: This type of error should not occur under normal operations where the ownership of all tables in the APM database (cemdb) should match the owner of the cemdb itself. By default that is the role "admin" which is the default username provided at cemdb install time.

If the username used in the tess-db-cfg.xml files is changed to be some other postgres role then new tables created for defects and stats. aggregation will be owned by the new role and that change can cause this type of problem.
