Oracle RAC GSD process
GSD (Global Services Daemon) is a cluserware process that was used in Oracle RAC 9i.
It runs on each node and coordinates with the cluster manager to receive requests from clients such as the DBCA, EM and the SRVCTL utility to execute tasks such as instance startup or shutdown.
With Oracle Clusterware 10g and 11g, the GSD resource does not have a function and will be disabled by default
It can be enabled in Oracle 10g or 11g if any Oracle 9i RAC components are present.

OC4J Resource Troubleshooting
[oracle@rac1 ~]$ srvctl start oc4j
OC4J could not be started
PRCR-1079 : Failed to start resource ora.oc4j
CRS-2501: Resource 'ora.oc4j' is disabled
we
need to enable and start the resource using
[oracle@rac1
~]$ srvctl enable oc4j
[oracle@rac1 ~]$ srvctl start
oc4j
Check the resource status
[oracle@rac1
~]$ crs_stat -t|grep oc4j
ora.oc4j ora.oc4j.type ONLINE

Now take a look at our GSD
resource
[oracle@rac1
~]$ srvctl status nodeapps
