Arguments

[ @secondary_database = ] N'secondary_database'

The database name on the secondary server. @secondary_database is sysname, with no default.

[ @restore_delay = ] restore_delay

The amount of time, in minutes, that the secondary server waits before restoring a given backup file. @restore_delay is int, with a default of 0, and can't be NULL.

[ @restore_all = ] restore_all

If set to 1, the secondary server restores all available transaction log backups when the restore job runs. Otherwise, it stops after one file is restored. @restore_all is bit, and can't be NULL.

[ @restore_mode = ] restore_mode

The restore mode for the secondary database. @restore_mode is bit, and can't be NULL.

  • 0 = restore log with NORECOVERY.
  • 1 = restore log with STANDBY.

[ @disconnect_users = ] disconnect_users

If set to 1, users are disconnected from the secondary database when a restore operation is performed. @disconnect_users is bit, with a default of 0, and can't be NULL.

[ @block_size = ] block_size

The size, in bytes, that is used as the block size for the backup device. @block_size is int, with a default of -1.

[ @buffer_count = ] buffer_count

The total number of buffers used by the backup or restore operation. @buffer_count is int, with a default of -1.

[ @max_transfer_size = ] max_transfer_size

The size, in bytes, of the maximum input or output request that is issued by SQL Server to the backup device. @max_transfer_size is int, with a default of NULL.

[ @restore_threshold = ] restore_threshold

The number of minutes allowed to elapse between restore operations before an alert is generated. @restore_threshold is int, and can't be NULL.

[ @threshold_alert = ] threshold_alert

The alert to be raised when the restore threshold is exceeded. @threshold_alert is int, with a default of 14421.

[ @threshold_alert_enabled = ] threshold_alert_enabled

Specifies whether an alert is raised when @restore_threshold is exceeded.

  • 1 = enabled
  • 0 = disabled.

@threshold_alert_enabled is bit, and can't be NULL.

[ @history_retention_period = ] history_retention_period

The length of time in minutes in which the history is retained. @history_retention_period is int, with a default of 1440.

[ @ignoreremotemonitor = ] ignoreremotemonitor

Identified for informational purposes only. Not supported. Future compatibility is not guaranteed.

Return code values

0 (success) or 1 (failure).

Result set

None.

Remarks

sp_change_log_shipping_secondary_database must be run from the master database on the secondary server. This stored procedure performs the following steps:

  1. Changes the settings in the log_shipping_secondary_database records as necessary.

  2. Changes the local monitor record in log_shipping_monitor_secondary on the secondary server using supplied arguments, if necessary.

Permissions

Only members of the sysadmin fixed server role can run this procedure.

Examples

This example illustrates using sp_change_log_shipping_secondary_database to update secondary database parameters for the database LogShipAdventureWorks.

EXEC master.dbo.sp_change_log_shipping_secondary_database
    @secondary_database = 'LogShipAdventureWorks',
    @restore_delay = 0,
    @restore_all = 1,
    @restore_mode = 0,
    @disconnect_users = 0,
    @threshold_alert = 14420,
    @threshold_alert_enabled = 1,
    @history_retention_period = 14420;
