Yes, that's correct, if you install ASM on a single node, the installer will detect that no clusterware is running, and it will install ocssd.bin to run from /etc/inittab. The ocssd.bin binary is in the ASM ORACLE_HOME, so, there won't be a clusterware home installed at all. If you install ASM on a cluster, ASM will detect the clusterware (since you're required to install it before ASM), and so won't enable ocssd.bin setup in the ASM ORACLE_HOME.

Hope that's clear,

-Mark

Hi Mark,

Thanks for the help.

localconfig add did the trick, see below (for info).

So does that mean that before I installed CRS when I had a database running with ASM, I had this sliver of CRS running under the covers?

What I've done so far is:

-1- Build simple DB
-2- create an ASM instance
-3- migrate the simple DB to ASM
-4- install CRS and screw things up

Things went wrong so I decided to remove CRS (services, but not the CRS home) and restart from there. So at step 2 or 3 above, I had some sort of cut down version of CRS running?

Regards
Tony
