IBM System/36 Environment: Maximum Descriptions
This document describes device description naming limitations and resulting messages for the IBM System/36 environment.
Resolving the problem
IBM OS/400 or i5/OS device description names can be up to 10 characters. The IBM System/36 Environment (S36E) device IDs are limited to 2 characters. Much of the information specified for the System/36 Environment concerns mapping between OS/400 or i5/OS device names and the System/36 Environment device IDs. OCL, application programs, menus and $SFGR displays depend on a 2-character ID to run in the System/36 Environment.
The System/36 Environment configuration maps between the OS/400 or i5/OS device description names and the System/36 Environment IDs for displays, printers, tape drives, and a diskette drive.
The maximum number of 1128 device IDs can be supported with the 2-character System/36 names. The first character can be one of the letters A-Z, $, # or @. The second character can be one of the letters A-Z, a number 0-9, $, # or @. The IDs F1, #d and #P are not used; T1, T2, TC and I1 are reserved for tapes and diskettes, respectively.
Once all of the System/36 Environment 2-character IDs have been used, the System/36 Environment configuration ignores any new devices added to the system. This may cause applications to fail with message SSP0134, Work station &1 is not known to System/36 Environment.
Recovery from Message SSP0134:
|1.||Device IDs can be manually removed from the configuration map using the CHGS36 command.|
|2.||IBM-supplied program QEXRMVDE can be used to remove devices from the System/36 Environment configuration. Instructions and parameters for using this program are described in the System/36 Environment Reference manual (SC41-4731), Appendix E.|
|3.||To benefit from changing the System/36 Environment attribute, add only System/36 Environment users. On the operating system command line, type the following:
Press the Enter key.
5. If not all users are running in the System/36 Environment, set system value QSPCENV to *NONE to ensure user profiles do not start
S36E by default.
6. Use device naming on PC5250 or third-party display sessions running S36E to ensure that the display devices will be mapped to a S36E
device ID only once.
