what is GMS_STATE in cmviewcl output

[jagdeesh]

I have two node cluster. The ServiceGuard OPS edition A.11.13. When i issue a command cmviewcl the output is as follows.

NODE STATUS STATE GMS_STATE
noden2 up running halted

PACKAGE STATUS STATE AUTO_RUN NODE
pkgp2 up running enabled cciln2
pkgtp up running enabled cciln2
pkgmq up running enabled cciln2

NODE STATUS STATE GMS_STATE
noden3 up running halted

PACKAGE STATUS STATE AUTO_RUN NODE
pkgp3 up running enabled cciln3

in the above output, what is GMS_STATE of the node and why it is always down. This particular column is available only in ServiceGuard OPS A.11.13. If you take A.11.14 or MC/Service guard it will not be there. Can any one help in this query???

thanks in advance.

Hi,

According to the 'cmviewcl' man page:

GMS_STATE When the ServiceGuard OPS Edition product is installed, this field indicates whether or not the Group Membership Service is running.

Do you have a group defined?

Hi,

GMS is Group Membership Service.

Accordng to my ServiceGuard training course notes:

"a process monitoring service built on top of ServiceGuard, improves availability of nodes running OPS instances, enables multiple OPS databases in a cluster, enables multiple OPS instances on a node."

Check your cluster ascii file to see whether GMS_ENABLED is set to yes or no.

regards,

Darren.

Ooops - pressed submit too quickly!

Should also have stated that GMS_ENABLED should be set to no for OPS 8.1.6 and above.

This parameter is for compatability with earlier ServiceGuard releases.

Thank you all. I did't have any of Group Membership Services configured. So that can be the reason why it is showing halted.

ok. Its clear. Thank you all
