ERROR : oracle.sysman.emSDK.util.jdk.EMException occurs while starting the HTTP Server

Hi,

When I visited the Oracle enterprise manager this morning to start up the OC4J_BI_Forms System component, found that the HTTPS_Server status was displayed as unknown.  When I tried to Re-start the HTTP Server got an error message "oracle.sysman.emSDK.util.jdk.EMException".  Checked EMD.log and found the following error description:

ERROR metricCache.item updateMatricResult.151 - oracle.sysman.emSDK.common.emdComm.MetricGetException: oracle.ias.sysmgmt.exception.ClusterManagementException::Cluster Manager init failure
Root Cause : Unknown Oracle_Home, "E:\ora9ias".

Yesterday we were testing database connectivity from a VB application using MDAC 2.7 which was failing.  As a result of this we installed Oracle 9i Client from the Oracle 9i Database CD and chose Administrator option while installing the client.  There is a separate oracle_home for the 9iAS DB, "ora92home" which we used while installing the client.  Could the client installation have impacted the IAS server?

Appreciate if you could please respond to this issue on priority.  

Regards,
Setty

Maybe this will be a little help for you, though this note from Metalink is about Oracle Forms:
...
Changes
Application of patch or installation of any other oracle product on the same folder as iAS server.

Cause
If there is an installation of database or any other oracle product over iAS release 1 installation, the deployment fails with FRM-92101. This problem can happen even when a patch is applied.

The reason is that the installation of a new Oracle product corrupts the registry key and the iAS server starts pointing to the new HOMEx and hence the deployment fails.

Fix
oracle.key file corrupted. The file in ORACLE_HOME\806\bin.

The oracle.key file needs to be altered.

For example it will read as "SOFTWARE\ORACLE\HOME0" instead of "SOFTWARE\ORACLE" which is iAS home.

Make the oracle.key file point to iAS home.
