You can use the Set Server/Output command to identify output log
    file names and locations for various database server processes.
    The following table shows valid values for the server-type
    parameter and the corresponding logical name.

    Table 15 Server Types and Logical Names

                       Server-
    Server             type       Logical Name

    AIJ Backup Server  ABS        RDM$BIND_BIND_ABS_OUTPUT_FILE
    AIJ Log Server     ALS        RDM$BIND_BIND_ALS_OUTPUT_FILE
    AIJ Log Roll-      LRS        RDM$BIND_LRS_OUTPUT_FILE
    Forward Server
    AIJ Log Catch-Up   LCS        RDM$BIND_LCS_OUTPUT_FILE
    Server
    Database Recovery  DBR        RDM$BIND_DBR_LOG_FILE
    Server
    Row Cache Server   RCS        RDM$BIND_RCS_LOG_FILE

    If the output file specification is empty (Output=""), the
    log file information for that server will be deleted from the
    database.

    If an existing logical name specifies an output file name for the
    specified server process, it takes precedence over the file name
    designated in the Set Server/Output command.
