(Doc ID 602633.1)

Last updated on JANUARY 13, 2018

Applies to:

Using a Grid Agent to monitor a Database.
The Agent version is certified to monitor a Database.

The <AGENT_HOME>/sysman/log/emagent.trc shows that the health_check metric is repeatedly failing for this database :

2008-06-09 15:21:11,173 Thread-3658 ERROR fetchlets.healthCheck: GIM-00105: file not found
2008-06-09 15:21:11,174 Thread-3658 ERROR engine: [oracle_database,dbname,health_check] : nmeegd_GetMetricData failed : Instance Health Check initialization failed due to one of the following causes: the owner of the EM agent process is not same as the owner of the Oracle instance processes; the owner of the EM agent process is not part of the dba group; or the database version is not 10g ( and above.

Repeated failure while executing this metric can cause the Agent to re-start, as it runs out of file handlers at the OS level.

 -  The database is a 64 bit installation but emagent executable is of 32 bit installation though the
64 bit agent software is installed.
-   Re-starting the database to create this hc_<SID>.dat file does not help in resolving the Healthcheck Metrics error. 
-  The <DATABASE_OH>/dbs/hc_<SID>.dat file has sufficient permissions to be read by the agent 


Database and Agent have been upgraded to from a lower version.
It is possible that when the Database / Agent were at (or below), this metric was not failing.
