23. Troubleshooting

24. Basic Approach Identify the problem component Record symptoms (error messages, response time). Locate related logfiles Review log files around time of exception for any related error entries. Resolve the error.

25. Web Server Oracle HTTP Server (Apache) $ORACLE_HOME/Apache/Apache/logs The following log files can be reviewed: Access Log Error Log SSL Log (If using SSL, and error is SSL related) $ORACLE_HOME oms10g

26. Web Cache Runs in Oracle HTTP Server home $ORACLE_HOME/Apache/Apache/logs Event.log Note 454533.1 Common Troubleshooting Techniques for OracleAS Web Cache Note 259796.1 OracleAS Web Cache event_log messages: Format and Meaning

27. Oracle Management Server Managed by opmn PATH=$ORACLE_HOME/oms10g/opmn/bin:$PATHexport $PATH Makes it easier to use correct opmnctl Start/Stop components individually opmnctl startopmnctlstartprocias-component=WebCacheopmnctlstartprocias-component=HTTP_Serveropmnctlstartproc process-type=homeopmnctlstartproc process-type=OC4J_EMopmnctlstartproc process-type=OC4J_EMPROV

33. Licensing

34. License basis Grid control free Infrastructure Repository Databases A separate Oracle Database can be installed and used as a Recovery Manager (RMAN) repository without additional license requirements, provided that all the Oracle databases managed in this repository are correctly licensed. This repository database may also be used for the Oracle Enterprise Grid Control repository. It may not be used or deployed for other uses. A separate Oracle Database can be installed and used as a Oracle Enterprise Manager Grid Control (OEM Grid Control) repository without additional license requirements, provided that all the targets (databases, applications, and so forth) managed in this repository are correctly licensed. This database may also be used for the RMAN repository. It may not be used or deployed for other uses Management packs do cost Management packs still cost without GC Eg awrrpt.sql

35. Plugins A wide variety of extra cost options http://www.pythian.com/news/mysql-plugin-for-oracle-grid-control Oracle-l (self developed sqlserver)

36. Conclusions Grid Control is a mature product. Grid Control can be complex. Probably not worth it for small installations < 5 databases/3 servers Strategic product
