I have been questioned as , If we are processing through millions of records and we get a SOC7 abend, so how do you find out where excatly its abended and how do you resolve this ??
When we run the program and it abends with SOC7, we have to take the last 4 bytes in compiler listing and check where excatly it got abended _________________ SONA KASI

I do not know what the last 4 bytes of a compiler listing might have that would identify an Abend at run-time. . .
Most organizations now use one or more tools that pin-point the cause of things like an s0c7 (Abend-Aid is one).
If the system has NO such tool, one must use the registers at the time of the abend to determine the next sequential instruction (nsi) and the core dump to find the problem instruction and then the problem data area (file or w-s or. . .). _________________ Have a good one
follow below steps..
1. when its gets abend you'll find OFFSET in the SYSOUT/SYSUDUMP
at entry offset +00000043A at address 00008116
2. recompile the program with source listing
in listing find the offset (here look for 043A) and find the line where the S0C7 occurred.
we know S0C7 happens due to invalid data.
To find invalid data out of millions of records
open the input file thru FILA. then type INVALID on command prompt, it'll shows all invalid records.
correct me if i'm wrong..
add something if i miss any..
i welcome for more in-depth details..
i think it will be rather revealing to troll thru nareshv 99's posts in other threads. _________________ Dick Brenholtz
