When tracing is enabled, this identifies the file name where the results are

to be output. The filename can be fully qualified with volume and

subvolume names. The file can be an edit-type disk file, spooler file or the

home terminal. If writing to a disk file and you anticipate a lot of trace

output, pre-creating the disk file with larger extent sizes than the product

will create is recommended. The product creates the disk file with extents

(14 pages, 28 pages, maxextents 559).) If the TRACEFILE becomes full,

HP Shadowbase will continue to run, but will not write anymore trace

output.

This parameter is used to define a Consumer transaction tracking file

which is used to prevent the CONS, following a restart, from reprocessing

transactions that it has already “ended” (completed). This is an alternate

method from the TIDFILE with TIDFILECONSTANT set to ON; however,

the TRACKTXFILE approach is significantly more efficient and should be

enabled in all cases where TIDFILECONSTANT was set to ON. This

method does not require TIDCLEAN to be run periodically to clean up the

TIDFILE. A given TRACKTXFILE must be unique across all CONS

objects. The file is updated by the CONS each time a transaction ends,

hence there is a heavy I/O load (but to a rather small set of records). Set

the <filename> to a local filename where the CONS is running. Like with

the TIDFILE, consider spreading multiple TRACKTXFILEs across disks

where appropriate.

Note: The new TRACKTXFILE (transaction tracking file) can only be used

with environments running a native collector (AUDCOLLN). The

TRACKTXFILE is an improved transaction tracking method that is

used in conjunction with the existing TIDFILE to prevent the replay

of transactions that have already been processed by a consumer.

Note: This file should only exist on a Master Audit Trail volume (MAT).

For questions about this, please contact HP Shadowbase Product

Management.
