Note: The root partition is required when using the HP audit reading

routines to access ENTRY SEQUENCED, RELATIVE, and

UNSTRUCTURED Enscribe files events, but NOT for SQL Tables -

if supplied it is not used (the reason it is not needed for SQL tables

is because the file label always includes a link back to the primary

partition). The HP ARLIB routines internally use it to convert the

record’s “key” information (the "offset" from the base of the partition

the event occurred in) for the audit trail event into the absolute

record “key” (the record “key” from the base of the primary partition)

for the file.

If the ROOTPARTITION is not supplied for a partitioned Enscribe entry-

sequenced, relative, or unstructured file, and an I/O occurs to a secondary

partition for that file that is to be replicated, HP Shadowbase will get an

error converting the “key” for that I/O, will log an error, and then shutdown

replication (usually this will be logged as a Guardian file error 23, “The

disk address is out of bounds”).

SBCMDFILE { ON }

3.961 3.962 OFF OFF ON No

In HP Shadowbase release 3.962, the LOADER was enhanced so that a

HP Shadowbase Consumer can determine if an audit trail event was

generated by the LOADER. In order for the Consumer to be able to

identify LOADER events, you must add a DBS object with the

SBCMDFILE parameter set to ON. The DBS SOURCEFILE parameter

should be set to the file name used in the TACL parameter PARAM

SBCMDFILE <file name>. A DBS TARGETFILE parameter is required.

The Consumer will automatically create the TARGETFILE command file

when you add the DBS object. A user exit can then call the API function

SBISLOADEREVENT to identify LOADER events.

SBDATAPREFIX <prefix>

Initial Changed

Version Version Values Default Value Specifications Alter

5.001 None Prefix up to 10 chars No

No Trailing Underscores

If specified, this is the character prefix used for the HP Shadowbase well

known column names. The specified prefix value is used to replace the

“SHAD” portion of the well-known column names. Well-known column

names will only be checked if INCLUDESBDATA is also set ON. The

prefix may be a maximum of 10 characters, and trailing underscores are

1 2 ... 266 267 268 269 270 271 272 273 274 275 276 ... 345 346
