Installation
Note: On Windows, you must stop the Datastore service before installing the update and follow the manual steps in the next section to apply the update.
For non-Wondows, the update can be installed through the PMT dashboard or command-line.
If you get the following error when installing the update using the Download or Download and Install option, ensure that the folder {pmt_install_home}/hf-updates has write permission: "Error occurred while installing PMT update. Please try again."
The backup is located at {pmt_install_home}/hf-updates/hf-2021-00003-329792/backup.
Installing the update manually
- Click the link to download the JAR. The MD5 checksum is: a76ee4fb7d5cbb16baa9037b84a6eb5b
- Execute the following command on the downloaded JAR. You must have privileges to start or stop Performance Monitoring Toolset and Datastore services.
Windows: <pmt_install_home>/jre/bin/java.exe -jar <jar-file-dir>/hotfix-003-329792.jar
Linux-based platforms: <pmt_install_home>/jre/bin/java -jar <jar-file-dir>/hotfix-003-329792.jar
Ensure that the JRE bundled with Performance Monitoring Toolset is used for executing the downloaded JAR.
Install the update from a user account that has permissions to restart Performance Monitoring Toolset and Datastore services.
