PROCESS_EXIT_COMMAND <command>
Used to run a command when the FairCom DB process calls the system function exit(). Before running the command, FairCom DB sets the following environment variables:
CTREE_PROCESS_ID is set to the FairCom DB process ID.
CTREE_SHUTDOWN_STATE is set to one of the following database engine shutdown status codes:
0 Shutdown not initiated.
1 Shutdown initiated.
2 Shutdown completed, but some clients remain active.
3 Shutdown completed with all files closed and final checkpoint logged.
Description
At shutdown the server calls the application indicated by the PROCESS_EXIT_COMMAND keyword within that application. It is possible to access the CTREE_PROCESS_ID and the CTREE_SHUTDOWN_STATE environment variables that exist within the scope of that application.
Example:
Create test.bat in the server executable directory, containing the following:
@echo %CTREE_PROCESS_ID% > shutdown.txt
@echo %CTREE_SHUTDOWN_STATE% >> shutdown.txt
Add this line to ctsrvr.cfg:
PROCESS_EXIT_COMMAND .\test.bat
Start the server and then stop it.
The content of shutdown.txt (created by test.bat) will be something like the following:
27700
3
Where 27700 indicates the c-tree server PID and 3 is the shutdown state (clean shutdown).
