problem that JDE has is performance issues related to some new values. It seems
that there can large performance hits if the logical files are not changed
as shown:
CHGLF FILE(F0003LA) ACCPTHSIZ(*MAX1TB)
Well, there are at least 300 (out of 1000's) logicals that I should do this for immediately. Is there a different way to submit this command so to change/update more than one file at a time? Using the keyword FILE(F0003*) does not work.
A: Use a command to create a list in a physical file:
DSPOBJD OBJ(JDELIB/*ALL) OBJTYPE(*FILE) OUTPUT(*OUTFILE)
Then use RCVF in a CL to read the records. Process only those record with ODOBAT = 'LF'. To process them sequentially, just do a CHGLF in the CL. If you want them to execute simultaneously, submit the CHGLF to a job queue and set MAXJOBS for the number you want to execute at once.
