Further image usage options include ALWAYSUSEAUDIT, (default) uses

the data value found in audit. Optionally, the user may specify

ALWAYSUSESOURCE and have the value retrieved from the source

record or row applied to the target. In either case, the final image of the

target after replication has caught up will always be identical to the source.

As of 5.002, FETCHSOURCE now supports Enscribe files in addition to

SQL/MP tables. The following options have been added to support

Enscribe files:

The short record warning options are SHORTRECWARN and

SHORTRECNOWARN. When set to SHORTRECWARN, an EMS

warning message will be generated if a short (with respect to the

compressed update image) record is fetched from the Enscribe source

file. For SQL/MP tables, this option has no effect. The default value is

SHORTRECNOWARN.

The short record behavior options determine how the Consumer will

proceed when a source record is fetched that is shorter than the length of

the compressed update image. When SHORTRECABEND is specified,

the Consumer will abend if this occurs. When set to SHORTRECSKIP,

the update event will be skipped. SHORTRECSENDCMP will cause the

compressed audit image to be applied as a compressed update. In

contrast, if SHORTRECSENDSRC is specified, the target will be updated

to the record fetched from the source file. For SQL/MP tables, the

specified short record behavior option has no effect. The default value is

SHORTRECSENDSRC.

The default value for FETCHSOURCE is OFF.

FIXUPDECIMAL is used to tell the Consumer what it should send to an

HP Shadowbase Other Servers when it detects nulls (binary zeroes) in a

field associated with an Enscribe source file. Note that if there is a dummy

SQL target table and this condition is detected and the related target

column is defined as nullable, null will be sent to the HP Shadowbase

Other Servers.
