2. Call the user exit SBSETDDLALLPTNS API function.

Note: There is a known issue with PURGE DDL replication that may

cause the target file to be purged when the source file is renamed. If the

source file or table resides on a physical drive and is renamed, the

Guardian OS will generate a PURGE event for the source file. If PURGE

event replication is enabled for the file, HP Shadowbase will receive and

process the PURGE event on the target, causing the target file or table to

be purged. Currently, there is no mechansim for HP Shadowbase to

distinguish between a PURGE event generated for a purge request and

one generated for a rename event. We have opened a case with HP to

provide a method to allow us to filter out rename PURGE events. Look for

updates to this issue in future product releases.

This parameter is used to indicate if a target file or table should be purged

or not when the CONS is creating a new target and detects that it already

exists. The default is OFF. Set it to ON to have the target purged,

otherwise set it to OFF.

Note: Care should be taken when enabling this parameter. Purging an

existing target file may be dangerous as that file may contain needed

information, or you may have inadvertently mistyped the file names in the

TARGETFILE DBS string.
