Special processing is likely in order to replicate Enscribe QUQUE files. By

default, the Consumer will abend if it receives an event associated with a

queuefile. ALLOWQUEUEFILE can be set to ON to allow the Consumer

to process the event.

If you need to process a queuefile, special user exit logic may be (and

often is) required. By default, Enscribe QUEUE files operate as FIFO

objects, meaning that the first record enqueued (enqueue operations are

replicated as INSERT events) is the first record removed by a dequeue

operation (dequeue operations are replicated as DELETE events). This is

because the default Enscribe QUEUE ordering scheme is via an internal

8-byte Julian timestamp as the high order part of the primary key. This

timestamp is guaranteed by the file system to always be increasing for

each successive enqueue operation. The Julian timestamp is file system

assigned when the event is enqueued, and cannot be assigned by HP

Shadowbase when HP Shadowbase enqueues that event into the target

QUEUE file. Hence, the “primary key” between the source and target

QUEUE files do not match. This means that, without user exit support, HP

Shadowbase does not know the correct key of the record to remove when

a dequeue operation is replicated.

This parameter is used to indicate that all local partitions (i.e., those

partitions on the COLL’s node), associated with the primary partition

specified in the SOURCEFILE parameter, are to be selected. The default

is OFF. When set to ON, the DBS SOURCEFILE must be set to a fully-

qualified file name and must be the primary partition.

The file name passed from the COLL to the CONS is for the primary

partition (the COLL replaces the secondary partition volume with the

primary partition volume name). Thus, the extended file statistics (STATS

AUD output) for the CONS will only show the primary partition because

the CONS only has the primary file in its selection/tracking list.

Note: Only local partitions are loaded into a COLL’s selection list. This is

because the COLL uses ARLIB to access the audit trail events, and

ARLIB can only access data for local files/tables, not remote files or

tables (or partitions thereof). If the COLL finds distributed partitions

for a file/table (i.e., partitions on other nodes), the condition is

printed to EMS. It is possible that HP Shadowbase replication may
