AIX Requirements
Imperva requires the DB to be started if it’s running on AIX, why is this an Imperva requirement?
- This is not an Imperva requirement, it is dictated by AIX design and processing
- This situation involves system call updates and how they are made available to the processes that need those calls to function as expected
- Specifically the system calls updated or newly added by the agent
- These system-calls are updated directly to the primary system-call table – aka svc table
- In addition to the main svc table there are copies of this table which are used by the various processes/applications
- In order to have the updated copy of the svc table we must restart the associated process/application
- Then after that those updated system calls can be used
- This is why a DB restart is required, so the agent can function properly by calling the most current system call.
- This requirement applies to both agent upgrades and new agent installs
- During an upgrade the system calls used by the agent can be upgraded
- For a new agent install we are introducing new system calls that were previously not registered.
