SAP Note 14941 - ISHCM communications module does not run on OSF/1

Symptom:

The transceiver of the SAP communication module cannot access the environment variables under OSF/1. In IS-HCM, return code 27 is displayed. As a result, the communications transaction always terminates.

Cause and prerequisites

Error in OSF/1 (2.0): in c-shell scripts started in the background, csh terminates with error message "close: bad filenumber".

Solution
If possible, switch to a different sh.

IS-HCM recommendation: change scripts to ksh; sample:

#!/bin/ksh -f
ISH_DIR=/usr/sap/...; export ISH_DIR
INTERF_NTISH=$ISH_DIR; export INTERF_NTISH
INTERA_NTISH=1; export INTERA_NTISH
cd $ISH_DIR
put_tab $@
