Could someone tell me what is this DBUA0 instance ?
I am playing around with Suse Linux 10.2, using dbua to upgrade a 10.2 instance to 11g. The instance is pretty basic, it doesn't even have the sample schemas installed and partitioning is the only extra featured installed. OEM was configured to run locally. Everything upgrades fine (with one small error that I ignore - ORA-04023: Object Sys.Standard could not be validated) and all objects are valid after the upgrade.
I have a couple of instances on my server, but I shut them all down while I do the upgrade on one instance - called "play". I am really puzzle by what looks like a new instance/DB being created by the upgrade process. "ps -ef|grep oracle" brings back

There is no reference in /etc/oratab
There is one file in $ORACLE_HOME/dbs ... hc_DBUA0.dat When I connect to the database in sqlplus, I get a message that the instance is not up.
I am wondering if this could be a special instance (somewhat similar to +ASM), but I can't find any information about it in tahiti or metalink.
Comments, clues or opinions would be appreciated Thanks. Received on Sat Jan 05 2008 - 05:56:56 CST
