When adding the keyword static to the F-Specs, the files stay open until the
get explicitly closed with the OPCode close or until the activation group
ends.

Betreff: RE: RPG ILE Problems (Activation Groups)
Hi ,
If I have a RPG module in a service program and I have an RPG procedure
defined with P specs, and I coded the F spec within the procedure,
the file would be automatically closed when the procedure ends.
If I do DSPJOB OPTION(*OPNF) OUTPUT(*PRINT) in the CL program
before and after you do the call to the service program, no files are open
and closed in this scenario (like you said).
My question is about the performance:
if the service program is called a lot of times , to open and close the same
file thousands of times, it´s correct ? how can avoid this ?
If no procedure are used the file it´s not open and closed each time, it´s
better for performance ?
but the RCLRSC Can not be used !!!! (cause all are in the DAG)
Could be a good idea have all the programs in the DAG (with *caller) and
only the service programs in the QILE
then if I need I can reclaimed the qile activation group??
Thank you.
Lluis

Now your example works and I understand.
If I open a file inside the SRVPGM and do RCLRSC and error ocurrs like
you said.
But if SRVPGM has a PI and open the file inside the PI no error occurs.
it´s correct ? why ?
Luis, I'm not sure what you mean by "SRVPGM has a PI".
But anyway, the syntax of the RPG code doesn't matter. The scenario
that will cause the problem is that the RPG module is in a service
program, and that the RPG module uses a file which is still open when
the RPG procedure returns to its caller.
Try adding a DSPJOB OPTION(*OPNF) OUTPUT(*PRINT) in your CL program
before and after you do the RCLRSC, to see if there are any files that
are open and that get closed by the RCLRSC.
If you have an RPG procedure defined with P specs, and you coded the F
spec within the procedure, like the procedure below, the the file would
be automatically closed when the procedure ends.
P c b export
Fqsysprt o f 80 printer
D prtDs ds 80
D line 80 inz('printer line')
D fld s 20a inz('init')
/free
dsply 'new value for srvpgm field' '' fld;
write qsysprt prtDs;
return;
/end-free
P c e
But if you coded the STATIC keyword on the F spec, then the problem
would occur, because the file would stay open when the procedure ends.
P c b export
Fqsysprt o f 80 printer static
...
Just a reminder, when working with service programs running in the DAG,
make sure you sign off and sign back on after changing the service
program. Or submit your tests to batch so you always get a fresh job.
