Hi Tony,

Problem is, even single-instance ASM needs a small sliver of clusterware to run. It's not a full blown CRS like you just deinstalled, it's a small subset of it. It's normally installed and configured when you do an ASM installation on a single node.

See Doc ID 745271.1 for details on doing a localconfig.

Hope that helps,

Still not there,......

I've run the following:

oracle_at_rac2:/mnt/oracle/10g/database> netca

Oracle Net Services Configuration:

    Deleted listener: LISTENER_RAC1

    Deleted listener: LISTENER_RAC2
Oracle Net Services configuration successful. The exit code is 0

then on both nodes (as root):

# local nosharedvar nosharedhome

all looked good

# install/

Removing contents from OCR device
2560+0 records in
2560+0 records out
10485760 bytes (10 MB) copied, 0.32744 seconds, 32.0 MB/s

rebooted both nodes.

What tells ASM is *still* in a cluster? The ocr has been blown away.
