Unloading PDS

• IEBCOPY COPY statement is used to unload a PDS to PS to create backup.
• IEBCOPY re-creates PDS from an unloaded PS by coding the output PDS physical organization (DSORG=PO and DSNTYPE=PDS or DSNTYPE=LIBRARY).
• A COPY operation can create an unloaded PS, whereas COPYMOD cannot.
• Multiple input PDS can unload into a single PS.
• UNLOAD and LOAD operations requests are very similar to a COPY operation.

Practical Example -

Scenario - Unload a PDS to a PS or backup a PDS.

Explaining Example -

• SYSUT1 DD DSN=MATEPK.IEBCOPY.INPPDS - Specifies the input PDS with members.
• SYSUT2 DD DSN=MATEPK.IEBCOPY.UNLOADPS,.. - Specifies the unload output PS.
• COPY INDD=SYSUT1,OUTDD=SYSUT2 - Unloads SYSUT1 data to SYSUT2.
