LiteSpeed for SQL Server 8.9.8 - Configure Log Shipping Guide

xp_objectrecovery_createscript

Creates DDL scripts. You can use this extended stored procedure to restore objects other than tables by generating the DDL scripts and then running the scripts in your native SQL Server tool (such as Management Studio).

NOTE:

When using scripts, the message output results are rendered in a multi row, single column result set so other products can programmatically acquire the script without having to parse the message results. The script then remains in the message output and result set locations.Object Level Restores from TSM Backups

Note: Delete backups is not supported in Maintenance Plans with this option.

@diffencryptionkey

Value used to generate the encryption key for the encryption algorithm. If you do not supply encryption key, then the program will not encrypt the backup. If you use the wrong encryption key, the restore will fail.

Caution: When encrypting data, take care not to lose the encryption key; a backup cannot be restored or recovered without the original encryption key.

Example of key: 'Mypassword'

Equivalent to @encryptionkey, but used for differential backups instead of full backup files.

@difffilename

Name of backup file to restore. Used for differential backups instead of full backup files. You can supply multiple instances of this argument.

@difffilenumber

Identifies the backup file within the backup set. Equivalent to @filenumber, but used for differential backups instead of full backup files.

@disablelogprocessing

Instructs LiteSpeed to skip all transaction log backups and tail log processing. This may improve read and recovery times. This argument accepts one of the following values:

  • 0—False (Default).
  • 1—True. LiteSpeed will entirely ignore any transaction log backups specified and will not process the tail log.

@encryptionkey

Value used to generate the encryption key for the encryption algorithm. If you do not supply encryption key, then the program will not encrypt the backup. If you use the wrong encryption key, the restore will fail.

Caution: When encrypting data, take care not to lose the encryption key; a backup cannot be restored or recovered without the original encryption key.

Example of key: 'Mypassword'

@filename

Specifies a backup location (e.g. C:\backups\AdventureWorks.bak). This argument accepts network destinations. You can supply multiple instances of this argument to use stripe backups.

@filenumber

Specifies the particular backup to use when recasting, restoring, extracting or reading from files with multiple appended backups. You can run xp_restore_headeronly to query the files contained within the backup set given by backup_file_name.

@FilestreamOnFileGroup

Specifies a file stream filegroup to include in the object restore.

@includetableobjects

Instructs LiteSpeed to script or recover one or more of the following:

  • Statistics
  • Triggers
  • All—All of the above

The value is a list of options, separated with commas.

@logencryptionkey

Value used to generate the encryption key for the encryption algorithm. If you do not supply encryption key, then the program will not encrypt the backup. If you use the wrong encryption key, the restore will fail.

Caution: When encrypting data, take care not to lose the encryption key; a backup cannot be restored or recovered without the original encryption key.

Example of key: 'Mypassword'

Equivalent to @encryptionkey, but used for transaction log backups.

@logfilename

Specifies location and name of the log backup file. You can supply multiple instances of this argument.

Syntax

@logfilenumber

Identifies the log backup file within the backup set. Equivalent to @filenumber, but used for log backups.

@LSM

Specifies handling for OLR LSM mapfile(s).

  • Create—Reads backup and creates a new mapfile. It will ignore attached LSM.
  • Keep—Does not delete mapfile(s) when complete.
  • Delete—Always deletes mapfile(s) when complete.

@objectfilename

Identifies a file that contains a list of objects. The format of this file is "ObjectType,ObjectName" per line.

You can create the list using xp_objectrecovery_viewcontents. xp_objectrecovery_viewcontents

@objectname

Specifies the name of the object to recover.

@OLRUDT

Create table script:

  • 0—Off. Create table with native types, if possible; othervise (CLR UDT) create with UDT. (Default).
  • 1—On. Create table with UDT.

@onfilegroup

Filegroup with the object to restore.

@PersistLogProcessing

Instructs LiteSpeed to persist log processing, so the same database backup does not have to be processed for each Object Level Recovery operation. This argument accepts one of the following values:

  • 0—False (Default).
  • 1—True. LiteSpeed will persist transaction log backups specified and the tail log for future use. This option can offer a huge performance gain for working with databases with large tail logs that could possibly take a long time to process.

@prefixtableobjects

Adds a prefix to the names of the table's objects you selected to script or recover.

@ProxyHost

The @ProxyHost argument is optional and specifies the name of the proxy host name that is running the proxy server.

note: If the @ProxyHost argument is not defined, then the LiteSpeed core engine checks the local .ini files for the proxy parameters. If the proxy parameters are not detected, then the LiteSpeed core engine connects directly to the proxy servers.

@ProxyLogin

The @ProxyLogin argument is optional and specifies the proxy server login credential.

note: If not defined, then the LiteSpeed core engine checks the local .ini files for the proxy parameters. If the proxy parameters are not detected, then the LiteSpeed core engine connects directly to the proxy servers.

@ProxyPassword

The @ProxyPassword argument is optional and specifies the proxy server password credential.

note: If the @ProxyPassword argument is not defined, then the LiteSpeed core engine checks the local .ini files for the proxy parameters. If the proxy parameters are not detected, then the LiteSpeed core engine connects directly to the proxy servers.

@ProxyPasswordEnc

The @ProxyPasswordEnc argument is optional and specifies the encrypted proxy server password credential.

note: If the @ProxyPasswordEnc argument is not defined, then the LiteSpeed core engine checks the local .ini files for the proxy parameters. If the proxy parameters are not detected, then the LiteSpeed core engine connects directly to the proxy servers.

@ProxyPort

The @ProxyPort argument is optional and contains the port number of the proxy server. The TCP/IP port values can be 1-65535.

note: If the @ProxyPort argument is not defined, then the LiteSpeed core engine checks the local .ini files for the proxy parameters. If the proxy parameters are not detected, then the LiteSpeed core engine connects directly to the proxy servers.

@scriptfilename

Name of the script file to save the generated SQL scripts.

@Status_FileName

Specifies the status of a backup location.

@stripedlogfilename

Specifies the striped log file name.

NOTE: The striped files for a given log backup must be specified before the next log backup set is specified.

@suffixtableobjects

Adds a suffix to the names of the table's objects you selected to script or recover.

@textimageonfilegroup

Destination TEXTIMAGE_ON filegroup name. Used to restore a BLOB (binary large object).

@type

  • TableTriggers 2
  • Trigger
  • Type
  • User 1
  • View
  • XmlSchemaCollection

Notes:
1 These values cannot be used to create scripts.
2 These values are pseudo-object types and are not real schema objects. They are only used to generate SQL scripts to alter the table, and they will be ignored when used with -V or xp_objectrecovery_viewcontents. When one of these values is used with -C or xp_objectrecovery_createscript, @ObjectName (-C) is not the name of the object, but the name of the owning table.
3 This value lists all object types, which are prefixed with "object_type, ". All pseudo-table object types will be listed even though they might not exist for the associated table.

@UseSSL

The @UseSSL argument specifies that the connection uses SSL security. This argument accepts one of the following values:

  • 0—Do not use SSL
  • 1—Use SSL (default)

@with

Each @with argument should be a syntactically complete and correct statement. Please refer to the SQL Server Transact-SQL backup and restore documentation for the syntax and usage.

The supported formats are:

  • @with='PARAMETER'
  • @with='PARAMETER=''accepted_value'''

NOTES:

  • Extended stored procedure arguments are limited to 255 characters. If you need more than 255 characters, use multiple @with arguments.
  • Do not supply the @with parameter if no additional features are required.

This extended stored procedure accepts the following @with parameters:

Parameter

Description

KEEP_REPLICATION

Instructs the restore operation to keep the replication settings when restoring a published database to a server other than that on which it was created (used when setting up replication with log shipping). You cannot specify this parameter with NORECOVERY.

MOVE

MOVE = ''logical_file_name'' TO ''operating_system_file_name''

Specifies that the given logical_file_name should be moved to operating_system_file_name. By default, the logical_file_name is restored to its original location.

If you use xp_restore_database to copy a database to the same or different server, the MOVE parameter may be needed to relocate the database files and to avoid collisions with existing files. Each logical file in the database can be specified in different MOVE statements.

Example:

EXEC master.dbo.xp_restore_database @database = 'MyDB'

, @filename = 'C:\MSSQL\Backup\MyDB_Backup.BAK'

, @with = 'MOVE ''MyDB_Data'' TO ''C:\MSSQL\Data\MyDB_data.MDF'''

, @with = 'MOVE ''MyDB_Data2'' TO ''C:\MSSQL\Data\MyDB_data2.NDF'''

, @with = 'MOVE ''MyDB_Log'' TO ''C:\MSSQL\Data\MyDB_log.LDF'''

NOTE: Use xp_restore_filelistonly to obtain a list of the logical files from the backup set. xp_restore_filelistonly

NORECOVERY

Instructs the restore operation to not roll back any uncommitted transactions. Either the NORECOVERY or STANDBY option must be specified if another transaction log has to be applied. If NORECOVERY, RECOVERY, or STANDBY is not specified, RECOVERY is the default.

SQL Server requires that the WITH NORECOVERY option is used on all but the final xp_restore_log statement when restoring a database backup and multiple transaction logs using LiteSpeed, or when multiple xp_restore_database or xp_restore_log statements are needed (for example, a full database backup followed by a differential database backup).

NOTE: When specifying the NORECOVERY option, the database is not usable in this intermediate, non-recovered state.

When used with a file or filegroup restore operation, NORECOVERY forces the database to remain in the restoring state after the restore operation. This is useful in either of these situations:

  • a restore script is being run and the log is always being applied.

  • a sequence of file restores is used and the database is not intended to be usable between two of the restore operations.

PARTIAL

Specifies a partial restore operation.

The granularity of the partial restore operation is the database filegroup. The primary file and filegroup are always restored, along with the files that you specify and their corresponding filegroups. The result is a subset of the database. Filegroups that are not restored are marked as offline and are not accessible.

RECOVERY

Instructs the restore operation to roll back any uncommitted transactions. After the recovery process, the database is ready for use.

If subsequent LiteSpeed restore operations (xp_restore_log or xp_restore_database from differential) are planned, NORECOVERY or STANDBY should be specified instead.

If NORECOVERY, RECOVERY, or STANDBY is not specified, RECOVERY is the default.

When restoring backup sets from an earlier version of SQL Server, a database upgrade may be required. This upgrade is performed automatically when WITH RECOVERY is specified.

REPLACE

Instructs LiteSpeed to create the specified database and its related files even if another database already exists with the same name. The existing database is deleted.

When the this option is not specified, LiteSpeed performs a check to ensure that the database is not restored to the current server if:

  • the database named in the xp_restore_database statement already exists on the current server, and

  • the database name is different from the database name recorded in the LiteSpeed backup set.

LiteSpeed will overwrite an existing file which cannot be verified as belonging to the database being restored. Normally, LiteSpeed will refuse to overwrite pre-existing files.

RESTRICTED_USER

When used in conjunction with recovery (another with param and the default) leaving a usable database, this restricts access for the restored database to members of the db_owner, dbcreator, or sysadmin roles.

STANDBY

STANDBY = ''undo_file_name''

Specifies the undo file name so the recovery effects can be undone. The size required for the undo file depends on the volume of undo actions resulting from uncommitted transactions. If you do not specify NORECOVERY, RECOVERY, or STANDBY, LiteSpeed defaults to RECOVERY.

STANDBY allows a database to be brought up for read-only access between transaction log restores and can be used with either warm standby server situations or special recovery situations in which it is useful to inspect the database between log restores.

If the specified undo file name does not exist, LiteSpeed creates it. If the file does exist, LiteSpeed overwrites it.

The same undo file can be used for consecutive LiteSpeed restores of the same database.

NOTE: If free disk space is exhausted on the drive containing the specified undo file name, the LiteSpeed restore operation stops.

STATS

Displays a message each time a percentage of the activity completes. The default is 10%.
CHECKSUM

Causes checksums to be verified when a LiteSpeed backup is created.

NOTE: When you restore a backup containing checksum, it is automatically checked. If you do not want to check the checksums during a restore, supply 'NO_CHECKSUM' .

PASSWORD Specifies the password for the backup set.
