Service Program Error

[Chris_Bougher@xxxxxxxxxxxxx]

I have a set of programs that use a service program. When they were first
implemented everything worked fine. One of the programs needed to be
changed a week later and after the change was made and the program put into
production everything started to break. The call stack was like this:

OPM Program in activation group default called
ILE Program in activation group ILE used
Srv Program in activation group SRVPGM

The error was coming from the service program and from a procedure that
shouldn't have even been called.

The fix after many hours of agonizing was to use UPDPGM command on the ILE
program. This worked but also increased the size of the program object
almost double. My question now is what happened to the bindings? Why did
the program increase in size after UPDPGM? Why did a procedure that was not
even called bomb?

Not the OPN and SRVPGM were not changed. and the change to the ILE program
did not involve any calls to the service program.

Thanks
