Can't start infrastructure ADMN-906025

Question

I reset the OracleAS 9.0.2 password using emctl set password <newpassword>. I did a dcmctl resyncInstance <myinstance>. Now when I try to start the infrastructure it fails on dcmctl start -ct ohs, reporting ADMN-906025. I used dcmctl getError ADMN-906025 to get the error message below, but that does not help.
ADMN-906025
The exception, 806212, occurred at Oracle9iAS instance "infra.<myhost.mydomain>"
"The opmn request has failed. From opmn: HTTP/1.1 204 No Content
Content-Length: 0
Content-Type: text/html
Response: 0 of 1 processes started.
Check opmn log files such as ipm.log and ons.log for detailed.".
Resolve the indicated problem at the Oracle9iAS instance where it occurred then resync the instance
I looked at the two logs and can find no errors.

Hi Donald,
in theory the emctl set password should have had no impact on the dcm shell not working.
The error you state I have seen before when there has been a failure in one of the underlying components. i.e. the OID or Database.
In 9.0.2 it is very important to start the various services in the correct order due to the dependency chain.
My advice would be to shutdown the database cleanly, i.e. shutdown immediate. Then stop/kill all the other oracle processes. I am assuming this will not impact users.
Now start the procs in the following order:
Start the database
sqlplus sys as sysdba
startup
Start the database listener
lsnrctl start
Start the oid bits and pieces
oidmon start
oidctl connect=iasdb server=OIDLDAPD instance=1 flags='port=4032' start
Use dcmctl to restart the middle tier
$ORACLE_HOME/dcmctl shell
>start
>getState -v
Start webcache (OPTIONAL)
Set the ORACLE_HOME to the ORACLE_HOME containing the webcache executable
$ORACLE_HOME/bin/webcachectl start
If you want the emd running (OPTIONAL):
emctl start
See if that recifies the issue.
cheers
