Explain why the emCCR cron job runs constantly.
Solution

After OCM is installed by whatever means into an ORACLE_HOME a cron job similar to the following may be present:



  0,15,30,45 * * * * JAVA_HOME=/u00/app/oracle/product/10.2.0.3/jdk /u00/app/oracle/product/10.2.0.3/ccr/bin/emCCR -silent start



The emCCR cron job is ensuring the OCM (and thus the internal OCM scheduler) is running.  When configured, the OCM process should always be running in the background so that the collection occurs every 24 hours by default.

If the emCCR cron job detects that OCM is running, it does nothing; if OCM is not running, the cron job starts it.  The job runs every 15 minutes.
