Where does emca get env variables Oracle 10gR2

[Norman Dignard]

I had a previous instance of oem running when we had to change IP & hostname. I've dropped
the db and agenet and, after the host rename.
tried to setup oem again with the cmd
emca -config dbcontrol -repos create

It fails to start however because its looking for the OC4J_DBCONSLE_rmdyintg.xxxx file seen below from the cfgtools/emca log

CONFIG: ps: cmd is not a valid field name
OC4J Configuration issue. /oracle/10gR2/oc4j/j2ee/OC4J_DBConsole_rmdyintg.deveng.local_nesad not found.

Where is emca getting the "rmdyintg" variable?? The file dir its looking for is created as /oracle/10gR2/oc4j/j2ee/OC4J_DBConsole_nesadev.deveng.local_nesad
Looking at the rest of the log all the config specs list nesadev.deveng.local which is the new host name. The old host name was nesatst. We also had another box call rmdyintg which has since been shutdown a year ago.

Oracle was a fresh install on this box when it was called nesatst. There are no other files/parms that I have found on the OS with "rmdyintg" so where is emca getting it?

It appears that on initial config it's doing a DNS/WINS lookup. I checked our DNS/WINS server (Windows 2003 AD) and the IP was registered to 2 differnt hosts names.

EMCA I guess just picked up the first one it discovered. After deleteing the dup IP/host, the problem did not reoccur.
