To find out cluster and daemon status

To start one offline daemon if ora.asm offline

crsctl start resource ora.asm -init

To manually start or stop oracle clusterware for all nodes by executing the following commands:

crsctl start cluster -all
crsctl stop cluster -all

And we can manage resources with srvctl tool.

srvctl manages six objects types which are asm, database, instance, services, node applications and listeners. And oracle 11gR2 adds an additional ten object types which are GNS, VIPAddresses, scan vip addresses, scan listeners, oracle homes, oc4j, servers, server pools, asm diskgroups and asm file systems.

srvctl provides alternative commands of

enable,disable, start, stop, relocate, status, add, remove, modify, config, getenv, setenv, and unsetenv to manager oracle grid infrastructure clusterware. And we can know these commands details by srvctl --h on operation system.

For example:

to start a service name raymond

srvctl start service -d ray -s raymond -n rac1

Another useful command to know is srvctl’s config option. This option retrieves information abouta system, reporting all database resources if no additional arguments are provided. If an object such as adatabase, asm, scans, or scan listener is passed, then this option provides detailed information about thespecified resource. This functionality is essential for deployments that GNS where DHCP is responsiblefor assigning network addresses. For example, you could use the following to find out which IP addressesare used for the SCAN:

srvctl config scan
