will cause alternate keys to be maintained automatically. Duplicate

SOURCEFILEEXTENT <primary extent size, secondary extent size,

maximum extents>

Initial Changed

Version Version Values Default Minimum Maximum Alter

3.990 (100, 100, 160) (2, 2, 16) (65545, 65535, 959) No

This parameter defines the extent size that will be used by AUDMON to

create a source pulse file. The default extent size is (100,100,160). That

is, the primary extent size is 100 pages, the secondary extent size is 100

pages, and the maximum number of extents allocated is 160. The valid

range for the primary extent and secondary is 2 through 65535. The valid

range for the maximum extents is 16 through 959. The

SOURCEFILEEXTENT parameter can’t be altered after a CAPTURE

command has been issued for the DBS object.

Note that this parameter needs to be configured large enough to hold the

pulse records that are being generated. The default extent sizes will hold

about 80,000 pulses.

Old pulse records are cleaned out every PULSERETENTION days. The

frequency of generating pulses (as defined by the PULSERATE

parameter) and whether or not multiple Consumers are using the same

pulse file, will determine the size needed (each pulse record is presently

about 400 bytes).

SOURCEREC recordname

Initial Changed

Version Version Values Default Value Specifications Alter

3.900 None Valid Enscribe DDL record name No

For Enscribe source files, this identifies the corresponding record name in

the dictionary containing the record format to be utilized. This is an

optional parameter. When replicating from Enscribe to Enscribe,

SOURCEREC is always coupled with TARGETREC. Therefore, in this

case, if you specify a SOURCEREC you must also specify a

TARGETREC. See TARGETREC parameter below.
