# ADASAV Utility Replication Functions

The following ADASAV RESTONL and RESTORE utility functions can be specified for the Adabas database and for the Event Replicator Server when using replication: FILES, FMOVE, and GCB. The parameters provided for use in replicating restored data using these utility functions are:

- RPLACTIVE is an optional parameter that specifies the inactive flag setting for a file during restore processing. Valid inactive flag settings are "YES", "NO", or no setting at all. A setting of "YES" turns off the replication inactive flag for a file. A setting of "NO" turns on the replication inactive flag.

  If no setting is specified, the default value is used. The default depends on the target database ID of the restore processing and its replication state. If any of the following conditions are met, the default is "YES"; otherwise the default is "NO":

  - The original replication is turned off.

  - The restore DBID is not the same as the original saved DBID.

  - The original replication target ID has been changed.

  - The original replication-before-image has been changed.

  - The replication primary key has changed.

  - The original replication is turned off.

  When restoring more than one file, the correct RPLACTIVE settings must be specified as positional values corresponding to the file numbers' positions in the FILES parameter file list.

- RPLDATA is an optional parameter that indicates whether the data in a file should be replicated to the replication target ID (RPLTARGETID parameter).

  Valid replication settings are "YES", "NO", "CREATE", or no setting at all. A setting of "YES" causes the restore function to replicate the file data to the replication target during restore processing. A setting of "NO" will not replicate the data to the replication target during restore processing. A setting of CREATE causes the restore function to replicate the file data to the replication target during restore processing, but also sends a "create file" transaction to the replication target. If no setting is specified, the default "NO" is used.

  Note
  Values of "YES" or "CREATE" can only be specified if replication is turned on for the corresponding file.

  When restoring more than one file in the FILE file list, the RPLDATA settings must be specified as positional values corresponding to the file numbers' positions in the FILES parameter file list.

  ADASAV RESTORE with the RPLDATA parameter will not replicate data for a file with spanned DS record support.

- RPLDSBI is an optional parameter that indicates whether the collection of before images of data storage should occur for an update command to a file.

  Valid RPLDSBI settings are "YES", "NO", or no setting at all. A setting of "YES" indicates that the collection of before images of data storage will occur for the file during restore processing. A setting of "NO" indicates that the collection of before images of data storage will not occur for the file during restore processing.

  If no setting is specified, the default value is used. The default depends on the target database ID of the restore processing and its replication state. If the restore DBID is the same as the originally saved DBID and REPLICATION=YES in the target DBID, the default is "YES"; otherwise the default is "NO".

  Note
  A values of "YES" can only be specified if replication is turned on for the corresponding file.

  When restoring more than one file in the FILE file list, the RPLDSBI settings must be specified as positional values corresponding to the file numbers' positions in the FILES parameter file list.

- RPLKEY is an optional parameter that specifies the primary key for replication.

  Valid RPLKEY settings are a two-character field name, "OFF", or no setting at all. Specifying a field name identifies that field as the primary key for replication. A setting of "OFF" indicates that no primary key should be used for replication.

  If no setting is specified, the default value is used. The default depends on the target database ID of the restore processing and its replication state. If the restore DBID is the same as the originally saved DBID and REPLICATION=YES in the target DBID, the original RPLKEY value for the file is used; otherwise the default is "OFF".

  Note
  A primary key can only be set if replication is turned on for the file and if the field name is a valid Adabas field according to the field definition table (FDT) for the file. When a new RPLKEY is specified it will not be confirmed as a valid Adabas field until the end of the ADASAV run. At that time, if any RPLKEY is found to be invalid, a warning message is issued, the RPLKEY is set to "OFF", and condition code 8 is returned.

  When restoring more than one file in the FILE file list, the RPLKEY settings must be specified as positional values corresponding to the file numbers' positions in the FILES parameter file list.

- RPLTARGETID is an optional parameter that specifies the target ID of the Event Replicator Server to which the restored transactions should be sent. .

  Valid RPLTARGETID settings are a valid target ID, "OFF", or no setting at all. Specifying a target ID identifies that as the target for replication. A setting of "OFF" or "0" indicates that no replication target should be used for replication.

  If no setting is specified, the default value is used. The default depends on the target database ID of the restore processing and its replication state. If the restore DBID is the same as the originally saved DBID and REPLICATION=YES in the target DBID, the original RPLTARGETID value for the file is used; otherwise the default is "OFF".

  Note
  A replication target ID can only be specified if replication is turned on for the file.

  When restoring more than one file in the FILE file list, the RPLTARGETID settings must be specified as positional values corresponding to the file numbers' positions in the FILES parameter file list.

- The RPLUPDATEONLY parameter can be used in the ADASAV RESTONL function to indicate whether an Adabas database file may be updated only by the Event Replicator Server as part of Adabas-to-Adabas replication or by other means as well. This parameter is optional.

  Valid values are "YES" or "NO". A value of "YES" indicates that the file can only be updated via Event Replicator processing; a value of NO indicates that the file can be updated by any normal means, including Event Replicator processing.

  If no value is specified, the default RPLUPDATEONLY setting of the file at the time of the corresponding SAVE operation is used.
