Re: Cobol programming issues

[Jon Paris <jon.paris@xxxxxxxxxxxxxx>]

Type of COBOL? ILE or OPM?

If ILE what Activation group is the COBOL running in? 

How do the COBOL programs return?

Any chance that there is a record lock involved?

Upon drilling down, we found that a simple READ statement (COBOL side) is consuming about 110 ms, which is huge comparing to the normal status (average time was less than 1 ms normally)!
