oracle 11gR2 RAC “oc4j” and “gsd” resource offline



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    ONLINE    rac1    

Now take a look at our GSD resource
[oracle@rac1 ~]$ srvctl status nodeapps
VIP rac1-vip is enabled
VIP rac1-vip is running on node: rac1
VIP rac2-vip is enabled
VIP rac2-vip is running on node: rac2
Network is enabled
Network is running on node: rac1
Network is running on node: rac2
GSD is disabled
GSD is not running on node: rac1
GSD is not running on node: rac2
ONS is enabled
ONS daemon is running on node: rac1
ONS daemon is running on node: rac2
eONS is enabled
eONS daemon is running on node: rac1
eONS daemon is running on node: rac2  
From the above output it is evident that gsd is disable so, enable that and start it 
[oracle@rac1 ~]$ srvctl enable nodeapps
PRKO-2414 : GSD is already enabled on node(s): rac1,rac2
PRKO-2415 : VIP is already enabled on node(s): rac1,rac2
PRKO-2416 : Network resource is already enabled.
PRKO-2417 : ONS is already enabled on node(s): rac1,rac2
PRKO-2418 : eONS is already enabled on node(s): rac1,rac2
[oracle@rac1 archive]$ srvctl start nodeapps
PRKO-2421 : Network resource is already started on node(s): rac1,rac2
PRKO-2420 : VIP is already started on node(s): rac1,rac2
PRKO-2420 : VIP is already started on node(s): rac1,rac2
PRKO-2422 : ONS is already started on node(s): rac1,rac2
PRKO-2423 : eONS is already started on node(s): rac1,rac2


Finally Check the resources status
[oracle@rac1 ~]$ crs_stat -t
