UNIX needs write access to
/tmp, or another
directory that is referenced by the
TMPDIR variable, to be able to process certain
commands during started task startup. z/OS Explorer uses the following
logic to set
TMPDIR during started task startup.
During started task startup, z/OS Explorer checks whether
TMPDIR is already set (DD STDENV). If so, the started task uses that value. If
TMPDIR is not set, the started task will test whether it can use
/tmp. If not, the started task will test whether it can use the home directory that
is assigned to the started task user ID. If this directory cannot be used either, startup fails.
/tmp, then you have to predefine
TMPDIRusing DD STDENV, as in the following sample:
/etc/zexpl/rsed.stdenvin this example) that will hold the
TMPDIRdefinition. You can edit the file with the TSO OEDIT command. The content of this file looks like the following sample:
Make sure the directory
TMPDIR points at, for example,
/my/tempdir, is available.
