In Oracle 11g RAC, the Discovery oc4j and the GSD service are in the offline state, which is the Oracle 11g RAC default scenario. Even so, it does not affect the use of the database because OC4J is a resource for WLM and WLM is available in 11.2.0.2. GSD is an interactive tool for supporting dbca,srvctl,oem and so on. This article describes switching these two services to online.

- 5. About GSD
- The Global Services Daemon (GSD) runs on each node with one GSD process per node.
- The GSD coordinates with the cluster Manager-to-receive requests from clients such as the DBCA, EM,
- And the SRVCTL utility to execute administrative job tasks such as instance startup or shutdown.
- The GSD is not a Oracle instance background process and is therefore no started with the Oracle Inst Ance.
- GSD interacts with RAC's management tools DBCA Srvctl OEMs to perform administrative tasks such as startup and shutdown of instances.
- To ensure that these management tools are functioning properly, you must first start the GSD on all nodes.
- A GSD process supports multiple RAC.GSD processes on one node, located in the $oracle_home/bin directory.
- Its log file is $oracle_home/srvm/log/gsdaemon.log.
- For example:
- Assuming an OEM tool is used to launch an instance, the OEM passes the task to the appropriate smart engine, which generates a script file that contains the Srvctl command.
- The GSD process reads the script file and executes the script, and the GSD returns the execution result to the smart engine, which is near and the smart engine is returned to the OEM.
- For example, assuming that all instances are closed using the Srvctl tool, the GSD process accepts requests from the Srvctl tool and
- Executes the request on the local node and returns the execution result to the SRVCTL session.
