A STEPLIB is a set of private libraries used to store a new or test version of an application program, such as a new version of a runtime library. To improve performance of the z/OSĀ® shell, avoid propagating STEPLIBs by using one of the following options:
o If you enter the OMVS command either from ISPF or with STEPLIB data sets allocated, include the statements in the shell profile. For example: if [ -z "$STEPLIB" ] &&; tty -s; then export STEPLIB=none exec sh -L fi [ Lots more. There's a semicolon in there that mystifies me. I test "$-" for 'i' to identify interactive shells.
