Chapter 13: OpenVMS Server Configuration
Result: ELMC installs itself for all nodes.
l Cluster: All but two nodes share system disk A. The other two nodes share system disk B.
Install Node: A node that uses system disk A.
Install Target: The default location SYS$COMMON:[HP...].
Result: The other two nodes will not have ELMC.
In the previous case, you can install ELMC one more time for the remaining two nodes by running the
install from either node and again choosing the default location of SYS$COMMON:[HP...]. Consider
this a completely separate ELMC installation from the first install on the majority of the nodes.
l Cluster: All but two nodes share system disk A. The other two nodes share system disk B. All nodes
also mount a non-system disk C.
Install Node: Any node.
Install Target: A directory on disk C, specified by you during the installation.
Result: ELMC installs itself for all nodes.
Note: In all cases the installation package also lets you choose only a subset of the nodes that can
see the install location.
Archiving and Cleaning the Error Log
After WEBES is installed on the CMS, WEBES begins using ELMC to analyze all events stored in the
error log, which can result in high CPU usage over an extended period. To control this operation, you are
encouraged to archive and clean the error log before installing. This reduces the size of the log and the
time required for the initial scan.
Follow these guidelines for cleaning the error log. If ELMC is installed and running when you clean the log,
you do not need to stop and restart the Director process. Also, do not stop and restart the ERRFMT system
event logging process.
The default error log, typically SYS$SYSROOT:[SYSERR]ERRLOG.SYS, increases in size and remains
on the system disk until the user explicitly renames or deleted it. When either occurs, the system creates
a new, clean error log file after about 15 minutes.
Caution: After renaming or deleting the existing log, do not install ELMC until the new default log is
present.
If you rename the log, the saved log can be analyzed at a later time.
Aside from starting with a clean log before installing WEBES, you may want to perform regular
maintenance on the error log. One method is to rename errlog.sys on a daily basis. For example, you
might rename errlog.sys to errlog.old every morning at 9:00. To free space on the system disk,
you then can back up the renamed version to a different volume and delete the file from the system disk.
