OPNBACK Mark Open Files to be Saved

ONXOPNBACK [= Y | N]

Normally, a file which has been opened in Write or Update mode (Open=Output/Update /Extend/Inout/Outin) cannot be backed up with ARCHIVE. This Variable Action will set a bit in TSOSCAT which will enable the file to be secured in spite of its Open status. A prerequisite for this is BS2000, from OSD V1.0, and that PARAM OLS=YES has been specified. The user is responsible for the consistency of the data in this case.

The file may not be locked when the OPNBACK Variable Action is executed. The ONXVERIFY Variable Action can be executed beforehand.

The possibility of saving open files was primarily meant for UDS databases. Another use would be for example for PLAM libraries that contain active SYSOUT files. Although a restore operation may result in an individual element being in an inconsistent state, this option does at least provide the possibility of saving an open library.

Y The OPNBACK indicator should be set permanently in the system catalog for the marked files.

N The OPNBACK indicator should be reset for the marked files.
