Mainframe, MVS and zOS Discussion

I have one interview question if anybody knows answer:

There is a DB2 table in both TEST and Prod regions,

I wanted to compare both and restore test table with prod wherever it is not matching.

How can we do in COBOL-DB2 Program?

It's my pleasure Anuj!

If I simply ask how should I look for the opprotunities which can be used for buffer-pool optimization for an LPAR over all, is there any way you'd suggest please?

For a couple of months I am working on buffer pools with following agenda: 1) They need to be increased in size. 2) Buffer pool parameters (VPSEQT,VDWQT) need to be modified. 3) 1 MB page frame allocation. 4) Segregation of tables according to their access in different pools Before I can pursue abov...

I'm Prasad. I work with COBOL, JCL, DB2 and VSAM.

I was wondering that to know about VSAM what all should I know?

I'm from India.

Found you on google for a file-aid question.
