ECC 6.0 failover problem

Former Member

Hi,

I have also installed ecc 6.0 in Aix 5.3 with oracle 10G.

We have 2 physical servers and in one server i have installed

both the CI & DB instance and in another server i have installed the application server(dialog instance). and it is also a failover concept.

When i stop my ci&db server all the mount points are comming into my application server thru hacmp clustering but i am not able to start my sap manually in my application server.

Is there anything to be done so that the sap starts?

Plz help me....if u can u can also mail me at sashwinkumar@gmail.com

Regards

Ashwin

Hi Raja,

Do the DB starts? When you installed the CI+DB, made it Cluster IP and Cluster Alias dependent? Do you have any error log or trace?

Maybe with this information we can help...

Hi,

Thanks for ur reply.

No my db doesnot start......

it says cannot find executable sqlplus.

When i tried starting from sqlplus connect /as sysdba

its throwing a error ORA-12547: TNS:lost contact.

Then what do u mean by cluster ip and cluster alias dependent.

All the ibm person has done is that they have made the clustering thru hamcp method.

When one server fails all the mount points and the ip will move to the other server.

That is all i know.

Any input will really help me.

Hi,

The cluster must have a mobile IP, and the IP must have a virtual hostname assigned (not the hostname of your server1 or server2). Then the tnsnames.ora, listener.ora must point to this virtual name.

The Sap instance profiles must have the virtual name defined too (usually the profiles with the server hostnames are links to the one containing the virtual name). I mean something like that:

lrwx------ START_DVEBMGS00_<server1> -> START_DVEBMGS00_<virtualname>

lrwx------ <SID>_DVEBMGS00_<server1> -> <SID>_DVEBMGS00_<virtualname>

lrwx------ START_DVEBMGS00_<server2> -> START_DVEBMGS00_<virtualname>

lrwx------ <SID>_DVEBMGS00_<server2> -> <SID>_DVEBMGS00_<virtualname>

-rw-rr START_DVEBMGS00_<virtualname>

-rw-rr <SID>_DVEBMGS00_<virtualname>

-rwxr-xr-x DEFAULT.PFL

Verify this. Hope this could help.
