The CPF recovery file is designed to hold TSS commands that
could NOT be propagated to another system(s) for whatever reason.
Once the communication link is reestablished, any commands in the CPF
recovery file should be propagated and then cleared from the file.
The CPF recovery file shouldn't wrap. If it does,
you will get a TSS9803W NO FREE RECORDS ON CPF RECOVERY FILE.
You can run the TSSCPR utility to see the commands in the CPF recovery
file. Columns 149-158 in the TSSCPR output show the date
the command was issued on the local node. If the date is recent,
check to see if the system(s) are down or connections lost.
If the date is not recent, the commands can be cleared via
TSS REM(*CPFRECV) CPFNODE(node) or TSS REMOVE(*CPFRECV) UNTIL(mm/dd/yy),
which will delete all records up to, and including, the specified date.
Create CPF Recovery File
If you intend to use CPF, format the CPF recovery file through TSSMAINT. The size of each record in the CPF recovery file is 4500 bytes. The block size should be a multiple of this value.
