Optional Parameter

RECOVER
Completes previously interrupted VSAM processing. The data set cannot be opened on any system; otherwise, the command will fail with an OPEN error.

Recommendation: When sharing data sets between different processors, IBM® recommends that you run VERIFY as the first step of a job stream to prevent job termination caused by an open access method control block (ACB) error code if the other processor already has the data set open. IBM also recommends that you specify the RECOVER parameter after a key-sequenced data set has been closed improperly.
