Sometimes it's not possible to install a product installation package (PAX file) via Mainframe Software Manager - MVS. This document describes the unpaxing of the file before the SMP/E installation can start.
Here a sample JCL to unpax the software installation package (PAX file):
// Insert valid Jobcard //* //********************************************************************* //* UNPAX into an EXISTING USS directory for z/OS products //********************************************************************* //UNPAXDIR EXEC PGM=BPXBATCH, list block spec files // PARM='sh cd /u/users/msmserv/msminstall;pax -rvf * // 20000168X01.pax.Z' //STDOUT DD SYSOUT=* //STDERR DD SYSOUT=* //* //
