For Forms versions 11.1.1.6.0, 11.1.2.0.0, and 11.1.2.1.0, if you installed the WebLogic and Forms environment using JDK 7 (NOTE: JDK 7 is not supported with Forms 11.1.2.0.0), if you attempt to make any modifications of any OHS configuration files in Enterprise Manager FMW Control, you will be presented the following error message:
“Failed to invoke operation load on MBean oracle.as.management.mbeans.register:type=component,name=ohs1,instance=asinst_1,Location=AdminServer”
To fix this error, go to %ORACLE_INSTANCE%\config\OHS\ohs1 ($ORACLE_INSTANCE/config/OHS/ohs1 in Unix) and open up admin.conf with a text editor (please make a backup of this file before making any edits to this file or any configuration file). Once in the file, look for the parameter “SSLProtocol nzos_Version_3_0”. Change this to: SSLProtocol nzos_Version_1_0 nzos_Version_3_0
After making the change above, save and close the file. Restart OHS from either OPMN or Enterprise Manager. After OHS has been successfully restarted, you should be able to make edits to OHS configuration files in EM.
NOTE: According to Oracle Support, this has been fixed with Oracle Forms 11.1.1.7.0.
UPDATE (7/2/14): There is also a known issue (also includes Forms 11.1.2.2.0) where the same error is produced due to a filename containing spaces in %ORACLE_INSTANCE%\config\OHS\ohs1\moduleconf ($ORACLE_INSTANCE/config/OHS/ohs1/moduleconf in Unix).
To fix the problem, rename the file containing spaces so that there are no spaces in it. After the file(s) has been renamed, restart the AdminServer. After doing that, the error should disappear.
