EXPORTING › EXPORT Optional Parameters › EXO | NOEXO

EXO | NOEXO

The EXO (EXPORT Open) parameter exports clusters that are currently open for output by another job. When NOEXO is in effect, clusters that are currently open for output by another job are skipped, but a warning message is issued.

Syntax

This parameter has no operands.

EXO

►►─┬───────────┬──────────────────────────────────────────────────────────────►◄
   ├─ EXO ─────┤
   └─ NOEXO ◄ ─┘

Usage Rules

The following usage rules apply to the EXO parameter:

• If an open cluster is encountered and EXO has not been specified, the export of that cluster is bypassed and EXPORT continues with the next cluster.
• When EXO is specified, EXPORT and RESTORE issue a message indicating the cluster was exported while open.
• EXO and DISP=OLD are mutually exclusive.
• CA FAVER does no enqueueing and does not attempt to coordinate its access with VSAM. If update activity occurs at the same time as EXPORT EXO, the backup file may not accurately reflect the contents of the cluster. EXO aids in exporting open clusters when there is no update activity and it would be impractical to close them (for example, in an inactive CICS system).
• NOEXO is the default unless the GVPARMS utility is used to change the default to EXO.
