Rec               (TST - Table)

DESCRIPTION
"Rec" indicates whether or not a local Temporary Storage (TS) queue is marked
for recovery.


VALUES
The possible values of "Rec" are:

   'Y' - the TS queue is recoverable
   'N' - the TS queue is not recoverable
   ' ' - the TS queue is not recoverable


INTERPRETATION
When a TS queue is recoverable, a system crash or transaction abort does not
interfere with the integrity of the queue. For recovery purposes, Sun MTP handles
a TS queue just like a database file, except that Sun MTP uses a specific file
for Temporary Storage, TEMPSTGR.  When a problem occurs, Sun MTP rolls back a 
TS queue's activity made by transactions not yet committed. Thus, a recoverable
TS queue is left in a consistent state relative to the committed processing.



CONCLUSIONS
Sun MTP can only perform recovery on a local TS queue, since a remote TS queue 
is not maintained by the local Sun MTP region. In order for a TS queue to be 
recoverable, two conditions must hold. First, the recovery facility must be 
activated for the entire Sun MTP system. The setup for this facility is located 
in the Sun MTP VSAM table. Second, the TS queue's definition in the Sun MTP
Temporary Storage Table (TST) must have the Recoverable field set to 'Y'. Note
that the Sun MTP TST allows you to specify a value for the Recoverable field.
However, such a value is ignored. If you leave the Recoverable field blank in
the Sun MTP TST for a local TS queue entry, Sun MTP interprets this as 'N', even
though the value does not show.
