OC4J Instance Failure

Question

Hi,
I'm currently install 9iAS R2 in w2k, however, it always failed to setup "OC4J Instance Configuration Assistant" at the end of installation, even Oracle9iAS Infrastructure or Oracle9i Application Server.
The error was:
Starting OC4J instance 'OC4J_DAS'..done.
Deploying application 'oiddas' to OC4J instance 'OC4J_DAS'..
ERROR: Caught exception during deploy.
oracle.ias.sysmgmt.exception.TaskException: The configuration files for this Oracle9iAS instance are inconsistent with the
configuration stored in the repository. In order to protect the repository,
no further configuration or deployment operations are allowed until the problem with the configuration on the filesystem is resolved. This condition arises when a prior operation was unsuccessful. Please check the logs located at
ORACLE_HOME/dcm/logs to determine why DCM was unsuccessful in updating
the configuration files on disk. Some possible causes are:
* permissions on files
* file contention issues on Windows NT
* EMD and dcmctl running concurrently
* internal Oracle error
After resolving the problem that prevented DCM from updating the configuration
files, you may use the dcmctl resyncInstance command to resolve the problem.
Alternatively, you can stop and then restart the active dcmctl or EMD
process and resyncInstance will automatically be performed.

Can anyone help me? Thanks!

If you have a corrupted repository you are pretty much done unless you have made a backup of the repo. I had what looked like a corrupted repository and when I contact Oracle support on it they said the best thing to do is reinstall because we may spend hours attempting to fix it and not get anywhere, one has to wonder if they even know how to fix it.
Another issue that I discovered is that there is an undisclosed bug with the repository that they are currently working on a fix for. It seems that if you issue dcmctl commands while the em is up you risk corrupting the repository. Now the AS9i admin documentation claims that you must have the em up for everything to function properly and that was bad news for me because the EM is so slow on my platform it is almost unusable and I opted to use the dcmctl for everything. When I brought this up to the support representative I was working with he told me that the documentation was incorrect and it would function fine with out the web enterprise manager up. Either way I would get in the habit of making backups of the repo before you do anything.
In your case I would reinstall the whole thing and when you reinstall you have to make sure that you completely remove all oracle references on the system. Inorder for you to have a successfull reinstall you have to have a completly clean system. Oracle produced a note on what you need to remove from the system inorder for a success reinstall, this document is however just for Unix so its not going to help you much. Last I checked the note wasn't public and consequently not available on metalink, I had to request it through Oracle support. The note is number 201977.1 if you can not access it and you want it let me know and I can send it to you.
