BIM-EPIC ACL Support General Requirements

Chapter 5. Activating and Deactivating BIM-EPIC 5-55

• ERDFILE=erdname

• MSG088=YES

If the ACL is in a VM environment, the BIM-EPIC Autoattach Feature must be installed, and

these additional startup configuration options must be specified:

• AUTOATT=YES

•

VM=YES

Please refer to the OPTION CONTROL STATEMENT portion of this manual for descriptions

of these options.

The library and sublibrary used in the ACLLIB lib.sublib parameter must exist prior to BIM-

EPIC startup.

BIM-EPIC places requests for ACL volume status changes (scratch, retain, eject,

inventory …) into members of this sublibrary for use by the BIM-EPIC Task Dispatcher. We

recommend that it be reserved/used for ACL support only. And, to make it easier to apply

BIM-EPIC upgrades, it should NOT be the one used to contain BIM-EPIC members.

For IBM ACLs, BIM EPIC’s EP ACL SYNC command is used to reconcile the ACL cartridge

status inventory (active or scratch) with the BIM-EPIC DSN. It can be issued from the

console at any time. The EP ACL SYNC command is invalid for Memorex, OPTI-TAPE, and

STK ACL’s since they do not provide an Inventory function.

For all ACLs, whenever a TSIDUTL SCRATCH function is executed, TSIDUTL will

automatically start a synchronization process at the end of its processing if the appropriate

synchronization control statement is present (SYNCIBM, SYNCMEM, SYNCSTK) as

described in the TSIDUTL portion of this manual).

For IBM ACL’s, when the EP ACL SYNC command is issued or the SYNCIBM statement is

present, BIM-EPIC requests an inventory of all cartridges in the ACL. For each cartridge in

the inventory, the ACL-Reported status (scratch or active) is compared to the status recorded

in the BIM-EPIC catalog. If there is a difference, BIM-EPIC changes the status in the ACL to

be the same as the status in the EPIC catalog.

Memorex, OPTI-TAPE and STK ACL’s do not have an inventory function so no comparison

with the BIM-EPIC catalog is possible. When the TSIDUTL SYNCMEM, SYNCOPT or

SYNCSTK control statement is present, a SET VOL nnnnnn TO SCRATCH STATUS

command is sent to the ACL for each volser in the BIM-EPIC Scratch Report.

SYNCOPT should be used with caution, and probably not at all. Refer to the SYNCOPT

command for an explanation of why this is so.
