Error when creating a new Reports Server instance

Question

Hi,
I have tried to create and start a new reports server instance using the following method:
1- Creating the report server instance:
rwserver server=%newrepserver% start
2- Stopping the OPMN:
*%ORACLEHOME%\opmn\bin\opmnctl stopall*
3- Adding a new server target to OPMN.XML
*%ORACLEHOME%\bin\addNewServerTarget.bat %newrepserver%*
4- Updating the configuration with new OPMN settings:
*%ORACLEHOME%\dcm\bin\dcmctl.bat updateconfig -ct opmn -v -d*
*%ORACLEHOME%\dcm\bin\dcmctl.bat resyncinstance -v -d*
5- Starting the OPMN again:
*%ORACLEHOME%\opmn\bin\opmnctl startall*
However, when I try to start the OPMN again, I receive the following error:
opmn id="##########:6200 5 of 6 processes started
ias-instance id=red.########.########.lan
++++++++++++++++++++++++++++++++++
ias-component/process-type-process-set:
*%newrepserver%/ReportsServer/%newrepserver%*
Error --> Process (pid=6888) failed to start a managed process after the maximum retry limit.
Log: %ORACLEHOME%\opmn\logs\%newrepserver%~ReportsServer~%newrepserver%
Any ideas as to why the reports server instance cannot be started?
I have tried rebooting the server many times and have recreated other reports server instances but with no luck.
Many thanks in advance,
Chris

On Windows this is caused most often by the temporary directory setting.
Change the temporary directory to some fixed directory writable by anybody, e.g. "C:\temp".
Change this in:
Registry entry: hkey_local_machine\software\oracle\key_<oashome>\REPORTS_TMP
<oashome>\opmn\conf\opmn.xml: search for environment variable TEMP (under ias-instance)
Good luck!
