Note: After a major release upgrade, the old and new versions of the services might continue to run concurrently for up to 24 hours. Ensure that the Secure Agent machine has sufficient free memory to avoid memory depletion during this period.
Perform the following steps to ensure that the Secure Agent is ready for the upgrade:
1Ensure that each Secure Agent machine has sufficient disk space and memory available for upgrade.
The machine must have sufficient available memory to run two Secure Agents simulatenously.
The machine must have at least 5 GB free space or the amount of disk space calculated using the following formula, whichever is greater:
Minimum required free space = 3 * (size of current Secure Agent installation directory - space used for logs directory)
2Close all applications and open files to avoid file lock issues, for example:
- Windows Explorer
- Notepad
- Windows Command Processor (cmd.exe)
Dynamic files in preprocessing commands
Data Integration refreshes mapping and task metadata during an upgrade. If you have a task that uses preprocessing commands to create a dynamic file, ensure that a file with the referenced file name is present at the specified file path before the first task run after the upgrade.
If a file isn't present, Data Integration can't map the metadata between the preprocessing command and the referenced file, and the task fails. After the first task run, Data Integration retains the file path.
