Hi Tony,
I can't locate any docs on it. Why I suspect it might be a constraint is that
DBCA lets you either run local (DB Control) or centralised management
(EMGC/EMCC etc) but not both. But if we take a look at the options for the emca
utility it does look like both central and local management can be configured
from the command line (taken from 11.2.0.3 btw):
emca -help
$ORACLE_HOME/bin/emca [operation] [mode] [dbType] [flags] [parameters]
-h | --h | -help | --help: prints this help message
-version: prints the version
-config dbcontrol db [-repos (create | recreate)] [-cluster] [-silent]
[-backup] [parameters]: configure Database Control for a database
-config centralAgent (db | asm) [-cluster] [-silent] [parameters]: configure
central agent management
-config all db [-repos (create | recreate)] [-cluster] [-silent] [-backup]
[parameters]: configure both Database Control and central agent management
..
Depending on how the original dbcontrol was configured you might need to
-deconfig the existing dbcontrol and then run a '-config all db' to have both
central and local management.
Regards,
Mark
