IGZEQOC

IGZEQOC is a COBOL library routine that is invoked when a QSAM file is opened or closed.

Hints

Significant CPU and wait time can result from excessive opens and closes of QSAM files. Typically, files are opened at the beginning of processing and closed when processing has finished. Excessive opens and closes might indicate that these operations are performed within a program looping structure. If this is the case, move the open/close outside the looping structure.
