Controls During Export

You can use EXPORT command parameters to control the following situations during an export:

Open clusters are encountered. By default, EXPORT does not back up a cluster or alternate index that is open for output. However, when you know that these objects are not being updated, you can use the EXO parameter to allow open objects to be exported.
Errors occur. By default, EXPORT continues to the next control interval if a corrupt CI is read, the next cluster if the current one cannot be read, or the next catalog if the present catalog cannot be opened or read. Specifying the ESTOP parameter causes EXPORT to terminate collectively or selectively.

Other EXPORT parameters set global options:

CA VSAMAID for z/OS. Statistics collection is done during the export.
Performance. Parameters are available to set the CA FAVER format file block size, the VSAM input buffer size, and the number of tape buffers.
