Applies to: Oracle Server - Enterprise Edition - Version: 10.2.0.2.0
This problem can occur on any platform.
Symptomsperl. exe program that is launched with the EM DBConsole is eating up all of their cpu resources -
50% processing and all RAM.
.
Verified the issue by the customer problem description, which shows that when the customer stop or
kill the EM DBConsole Service, the high CPU usage disappers.
CauseThere are system files that reference the c: drive when setting variables. There is no c: drive on
the system.
Bug 5005739 specified that the following files reference the c: drive which must be present:
%ORACLE_HOME%sysmanadminscriptsdbdb_common.pl
%ORACLE_HOME%sysmanadminscriptsdbdb_instance.pl
%ORACLE_HOME%sysmanadminscriptsdb
etlistenerUtil.pl
%ORACLE_HOME%sysmanadminscriptsdb
et
etAdmin.pl
Also chacke to make sure the TMP and TEMP system varialbes are set to a location where the drive exists
SolutionIf the c: drive does not exist then to implement the solution, please execute the following steps:
1. Change all references of c: over to e: (or a drive that exists) in the following files:
%ORACLE_HOME%sysmanadminscriptsdbdb_common.pl
%ORACLE_HOME%sysmanadminscriptsdbdb_instance.pl
%ORACLE_HOME%sysmanadminscriptsdb
etlistenerUtil.pl
%ORACLE_HOME%sysmanadminscriptsdb
et
etAdmin.pl
2. Make sure the TMP and TEMP system variables are set to a location that exists with at least
125Mb of free space. In this case TMP and TEMP should reference a temp directory on the e: drive.
