RE: Interconnect

I have the same warning in my alerts too. However my situation is unique. Solaris 10 64bit, Xiotech SAN, Oracle 10.2.0.1 RAC. Unique because I have 2 instances on this box and for the last 4 months SID-1 goes down every Wednesday and SID-2 every Saturday night at 11:59 PM. There are no error messages, core dumps etc., but the event happens faithfully. I raised a SEV-2 support and after 2 weeks of back and forth, Support took the most easy way out of trouble -- ' Your config is not supported, please reconfigure and open a fresh TAR if problems recurrs' :-)  

The unsupported thing about my config is that my RAC is Single Node.  

Thanks and have a good day.

I suspect that you might have not selected the correct/appropriate network settings during the CRS Install (3rd or 4th screen). Also, can you see you can invoke vipca to verify what the current settings look like (as root). Just a thought. Also, what does your crs_stat indicate?

Thanks

Hello.

We are doing a RAC install on RedHat Linux.[2.6.9-34.ELsmp #1 SMP ]. Currently on 2 nodes, Clusterware is installed successfully. OCFS2 of clusterware and ASM for database. ASM is working. Database not installed yet. All the components of clusterware working alright.

But, in the ASM laert I find:

 WARNING: No cluster interconnect has been specified. Depending on

           the communication driver configured Oracle cluster traffic
           may be directed to the public interface of this machine. 
           Oracle recommends that RAC clustered databases be configured
           with a private interconnect for enhanced security and
           performance.

oifcfg getif is not working. I don't get any reply.

Public is used in place of interconnect. We have collected RDA and working on SR. But you know even after uploading RDA results, analyst is asking what is the Linux version? :(

Any suggestion?

TIA,
Shiva
