Blocking file

[byan_haqi91]

Hi,

I have problem with my program. I have program that run in n-way. I want to speed up the performance of my program. I search the method until I found blocking file.
I tried the OVRDBF command to do blocking file. This is my code:

&DCBEGR = Begining record (RRN)
&DCENDR = End record (RRN)

ChgVar Var(&DCTOTL) Value((&DCENDR - &DCBEGR) + 1)
OVRDBF FILE(&NWFILE) POSITION(*RRN &DCBEGR) +
NBRRCDS(&DCTOTL) OVRSCOPE(*JOB) +
SHARE(*NO) OPNSCOPE(*JOB) SEQONLY(*YES)

I also tried:

OVRDBF FILE(&NWFILE) POSITION(*RRN &DCBEGR) +
OVRSCOPE(*JOB) SHARE(*NO) OPNSCOPE(*JOB) +
SEQONLY(*YES &DCTOTL)

I got message that I don't understand the error message:
Message ID . . . . . . : CPF0001 Severity . . . . . . . : 30
Message type . . . . . : Diagnostic
Date sent . . . . . . : 17/09/10 Time sent . . . . . . : 07:38:22

Message . . . . : Error found on OVRDBF command.
Cause . . . . . : The system detected errors in the command.
Recovery . . . : See the previously listed messages in the job log. Correct
the errors and then try the command again. *N instead of a command name
means that the name had not been determined before the error was found.

can you help me?

thanks,

I found it. it's because the maximum number is 32767 and I put 100.000 to NBRRCDS parameter.
