override this by setting the COLL parameter ARMAXIGNORECNT from 0

to 2147483647. When set to 0, TMFARLB2 will not return a “current audit

trail position” event. It will continue reading until it has an event to return

to HP Shadowbase for processing (i.e., setting the parameter to 0 mimics

the AUDCOLL ARLIB1 behavior). Note that ARMAXIGNORECNT can be

altered after the Collector has been started.

For AUDCOLLN Collectors only, the COLL object parameter was added in

release v3.970. By default, ARRETURNNDCRECS is set to OFF. When

OFF, this causes the Collector to call the HP TMFARLIB2 function

ARSTOPNONDATACHNGRECS to notify the audit reading library to not

return events associated with SQL partition maintenance operations

(these are table partition events that do not change the contents of the

rows in the table, only the partition where they are located on the NonStop

table) and not to return events generated by the activity of the RDF

updater on the RDF backup system.

When ARRETURNNDCRECS is set to ON, the call to

ARSTOPNONDATACHNGRECS is not made and events associated with

SQL partition maintenance operations will be seen and processed by HP

Shadowbase. This is the way that pre-3.970 HP Shadowbase worked and

the 3.970 non-native AUDCOLL works (because it uses TMFARLIB and

this feature is only available with TMFARLIB2).

Note that partition maintenance operations sometimes store insert and

delete events in the audit trail, and when these events are read, there is

no way to determine that they are partition maintenance operations versus

actual application insert and delete events. This new flag in ARLIB2

allows the new Collector to suppress these events from being returned to

ARLIB2 calls. See the documentation for the TMFARLIB2 function

ARSTOPNONDATACHNGRECS in the HP NonStop TMF Application

Programmer’s Guide for more information.

Note that you can alter ARRETURNNDCRECS after the Collector has

been started.
