Question

Hello!
Has anybody experinced this problem:
we have the following:
Server A, Windows 2000,2GB RAM, 9ias(9.0.2.0.0) [ infrastrcture, Portal, J2ee container, webcashe  ]
Server B, Database Oracle 9i
when accessing a portal page through Webcashe over SSL, the user receives the error message, "Portlet could not be contacted".
when accessing a portal page directly (not over SSL and not through WEBChache), results no error message.
The problem appeared when the tried to deploy an j2ee applications to OC4j,deployment failed and they rebooted the server.
http event_log contains the following error:

<MSG_TEXT>[TM] !!! Warning !!!
     We have detected multiple DCM management processes managing the iAS instance, "D:\oracle\9ias". If configuration changes or application deployment operations are executed while multiple management processes are running, inconsistencies in configuration can occur. It is highly recommended that just one DCM management process be running at a time. The management process may be in the form of either the dcmctl command line process or the EMD management process.
     If you have verified that only one management process is running and this message is still being logged, it is possible a management process was not shutdown down properly. Run "dcmctl shutdown -force" to properly shutdown the iAS instance and clean up any left over process state.</MSG_TEXT>

This is a synchronous problem between dcm proccesses.
You can solve it by installing 2591631 patch.
Also You should install 9.0.2.1 CorePatch before 2591631 patch.
And i want to tell that I think it isnt relevant about your problem "Portlet could not be contacted".
Good luck.
