Purpose: The REOPEN command can be used to close and reopen the
STEPLIB or SYSPRINT DD statement.
Syntax:
REOPEN {STEPLIB | SYSPRINT} Comments: The Dynamic Install Facility (DIF) opens STEPLIB during initialization, and normally keeps the file open until termination.
If the data set(s) allocated to STEPLIB are being modified during the day, DIF may receive a system abend 106 when starting a product usually long after DIF has been started.
Tip: The
REOPEN command can be used to
rebuild the extent table, which will allow the product to be started. If the SYSPRINT DD statement is allocated to a data set, the
REOPEN command can be used to clear the current data set.
Examples: To reopen the data sets allocated to the STEPLIB DD statement, use the following console command:
F DIF,REOPEN STEPLIB
