Installation information
Prior to installation
You can reduce the amount of disk space required for the backup of the /opt/ibm/wlp directory by performing this cleanup before installing the interim fix:
- Delete the /opt/ibm//wlp-backup-04 directory if it exists to free up disk space. This directory was created by a previous Cloud APM Hybrid Gateway interim fix install and is not needed if you are installing the latest interim fix.
- Delete file with names that start with javacore, heapdump or core in the /opt/ibm/wlp/usr/servers/hybridgateway/ directory
- Delete file with names that start with trace_ and messages_ in the /opt/ibm/wlp/usr/servers/hybridgateway/logs directory.
Installing
Installing the IBM Cloud Application Performance Management Hybrid Gateway update
1. Download 8.1.4.0-IBM-APM-GATEWAY-IF0008.tar from IBM Fix Central to a temporary directory (e.g. /tmp/if06-patch) on the computer where you installed the Hybrid Gateway.
2. Change your current directory to the download location, e.g.
cd /tmp/if08-patch
3. Expand the archive file using the tar command
e.g. tar -xf 8.1.4.0-IBM-APM-GATEWAY-IF0008.tar
4. Run the script hgpatch.sh:
cd 8.1.4.0-IBM-APM-GATEWAY-IF0008
./hgpatch.sh
Notes:
- If Hybrid Gateway services need to be stopped for the patch to be applied, you will be asked to confirm that you want to install the patch.
- When hgpatch.sh is complete, a summary is displayed showing the number of fixes that were installed, the number of fixes that were not installed because they have previously been installed, and the number of fixes that failed to install. If any fixes failed to install, more information can be found in the file hgpatch.log in the logs directory,
e.g./opt/ibm/hybridgateway/logs/hgpatch.log. - A record of each fix applied can be found in the
/opt/ibm/hybridgateway/fixesdirectory. Do not modify this directory or its contents. It is needed if other fixes are applied in the future.
Performing the necessary tasks after installation
The Hybrid Gateway interim fix installation logs are written to the /opt/ibm/hybridgateway/logs/hgpatch.log file.
After you have verified that the Cloud APM Hybrid Gateway is working ok with the new interim fix, you can delete the /opt/ibm/wlp-backup-08 directory to free up disk space.
Uninstalling if necessary
Files modified by the interim fix are backed up during the installation. If you encounter an issue with the interim fix and need to back it out then contact IBM support for assistance.
For detailed instructions to uninstall the hybrid gateway, please refer to the IBM Cloud Application Performance Management guide, here:
