Description: APM 9.5 installer binaries are missing the PowerpackForWebSphere_Agent.jar.

8. Could not start service 'TIM.Collection.Svc' on entity 25: the service did not stop. Unable to set or change the EM associated with a Service on the Services Tab. The Save button is greyed out.
https://support.ca.com/irj/portal/anonymous/redirArticles?reqPage=search&searchID=TEC604366
Description:
Problem #1:

Services including the Tim Collection Service, Stats Aggregation Service, or the DB Cleanup Service will not start. Looking at the appropriate EM log does not show the service running at all. For example, log entries for DailyAggregation will be missing if the Stats Aggregation Service is locked and cannot be started.

Problem #2:

You are unable to set or change the EM associated with a Service. This is normally done by selecting and saving a new EM from the Services Tab in the MOM's APM CE User Interface.

However, when accessing the Setup > Services menu and clicking on a Service link (i.e. Stats Aggregation Service), the Save button is greyed out. This should never be the case.

This article explains how to resolve the issue underlying both of these problems.

9. How to uninstall/reinstall a Windows installation of PostgreSQL software hosting the APM Database.
https://support.ca.com/irj/portal/anonymous/redirArticles?reqPage=search&searchID=TEC604029
Description: Sometimes it may be necessary to uninstall/reinstall PostgreSQL software e.g. errors during initial APM install, moving APM database to a new server etc.

10. Agent metrics are not getting reported in the Investigator tree due to breaching the agent metric limit
https://support.ca.com/irj/portal/anonymous/redirArticles?reqPage=search&searchID=TEC595877
Description:
In the case where some metrics from a specific agent are missing from the Investigator tree, and a similar warning like the following is logged in the IntroscopeEnterpriseManager.log then new metrics will not be accepted:

[WARN] [PO:WatchedAgentPO Mailman 2] [Manager.Agent] The Agent <agent_name> is reporting too many metrics (current=15000, max=15000).

This indicates that the agent has breached the metric limit threshold configured in the apm-events-thresholds-config.xml, thus no new metrics will be reported for that particular agent. However existing/historical metrics will continue to report.

11. Cannot read /etc.wily/cem/tim/logs/protocolstats/... [Errno 13] Permission denied
https://support.ca.com/irj/portal/anonymous/redirArticles?reqPage=search&searchID=TEC598181
Description: When trying to view the Tim packet Statistics or Timlog files, the browser is displaying an error indicating no permission to the file e.g.

Cannot read /etc.wily/cem/tim/logs/protocolstats1/2013-08-13.csv: [Errno 13] Permission denied: '/etc.wily/cem/tim/logs/protocolstats1/2013-08-13.csv'

Inspection of the file in the file system using 'ls -al' shows that the file permissions are:

12. Creating Frontends, Backends and App Map data for non J2EE applications
https://support.ca.com/irj/portal/anonymous/redirArticles?reqPage=search&searchID=TEC605137

13. Enterprise Manager crashed due to OutOfMemory in Java heap space
https://support.ca.com/irj/portal/anonymous/redirArticles?reqPage=search&searchID=TEC594141
Description: EM MOM crashed due to OutOfMemory in Java heap space. We had already specified -Xms1500m -Xmx1500m. We suspected a data or database corruption causing the problem. We brought the MOM up but it kept crashing. When the Heap Space issue appears, there is usually a lag in the garbage collection.

14. Google Chrome browser support for APM Webview and Java workstation Webstart.
https://support.ca.com/irj/portal/anonymous/redirArticles?reqPage=search&searchID=TEC604030
Description:
Question:
Google Chrome browser support for APM webview and java workstation webstart.

Answer:
Officially, Chrome is not supported. Unofficially we support Google Chrome (at least update 26) for Webview.

Explanation -
None of our UI support Chrome (though they are known to work fine in Chrome). The problem with Chrome is that we can't certify a specific version of it as it keeps updating itself and we cannot get a specific release of Chrome from the Google download site as it always gives you the latest version.

15. How do I know if I am running legacy or 9.1 new tracers?
https://support.ca.com/irj/portal/anonymous/redirArticles?reqPage=search&searchID=TEC602320
Description: An upgrade of legacy tracers may be needed for Agents running versions between 9.1.0.0 and 9.1.1.0 or when existing tracers were changed to legacy due to Agent Memory Technical Advisory. This article helps you determine if you are running legacy or 9.1 new tracers

16. How to Set a Workstation Alert for ConnectionStatus
https://support.ca.com/irj/portal/anonymous/redirArticles?reqPage=search&searchID=TEC593253
Description: There are 4 possible Connection States:

3 = disconnected

2 = connected, slowly or no data

1 = connected

0 = unmounted

Q. How can I build a threshold alert on a value of 0, unmounted?

When a JVM is restarted, it jumps to 3. Then it returns to 1 when connected.

When a JVM has been down for 30 minutes, it becomes "unmounted".
