After VAM is CANCELed by the oprator or abends, trying to restart VAM fails and displays msgs:
VAM0007 CA Allocate ALREADY INSTALLED
It has also been reported that this message is displayed:
CAHC101I Function: TERMINATE Return Code: x'00000008' Reason Code: x'00000004'
If the VAM task is no longer running, then enter this command which will remove
all hooks that are still installed which is what is preventing a normal Start:
When all the hooks are removed, then these messages are displayed and the task ends:
VAM0046 CA Allocate SHOULD INSTALL NOW
VAM0368 CLEANUP *** COMPLETED ***
So, you can now enter the normal Start command: S VAM
If you had received the CAHC101I message (along with the VAM0007 msg),
then when VAM has been started normally, the CAHC101I message can just be ignored.
Doing a search on it will get a hit that advises a PTF is needed for Common Services.
However, this is most likely not needed when VAM has started cleanly.
