JCL limitations for the PARM variable

The maximum length for the PARM variable is 100 characters, which might cause problems if you use custom directory names. To bypass this problem, use one of these options:
  • Use default values.

    The start.sh startup script can be started without arguments, in which case the default argument values are used if no environment variables have been predefined.

  • Use symbolic links.
    Symbolic links can be used as shorthand for a long directory name. The following sample z/OS® UNIX command defines a symbolic link (/usr/lpp/IBM/rseapi) to another directory (/long/directory/name/usr/lpp/IBM/rseapi).
    ln –s /long/directory/name/usr/lpp/IBM/rseapi /usr/lpp/IBM/rseapi
