Syntax: MIRRORED AUDIT [ AND DATABASE ] FOR sourcename AT hostname PORT "portnumber"
The Mirrored Audit option allows an Accessory to process transaction groups on a secondary system containing the mirrored audit files with minimal impact on the primary system. Special disk hardware or software duplicates the audit files on the secondary system. DBEngine will communicate with the Server Accessory on the primary system to determine the current (logical) end of the audit trail.
Put the MIRRORED option in a database-specific DBEngine parameter file (DATA/ENGINE/database/CONTROL). If you put it in DATA/ENGINE/CONTROL, then no matter what database the accessory wants to use, it will always try to get the information from the specified remote source.
