sp_add_log_file_recover_suspect_db (Transact-SQL)

  • Artikkeli

Applies to: SQL Server

Adds a log file to a database when recovery can't complete on a database due to insufficient log space (error 9002). After the file is added, sp_add_log_file_recover_suspect_db turns off the suspect setting and completes the recovery of the database. The parameters are the same as for ALTER DATABASE database_name ADD LOG FILE.

Transact-SQL syntax conventions

Syntax

sp_add_log_file_recover_suspect_db [ @dbName = ] 'database'
    , [ @name = ] N'logical_file_name'
    , [ @filename = ] N'os_file_name'
    , [ @size = ] N'size'
    , [ @maxsize = ] N'max_size'
    , [ @filegrowth = ] N'growth_increment'
[ ; ]

Arguments

[ @dbName = ] 'database'

The name of the database. @dbName is sysname, with no default.

[ @name = ] N'logical_file_name'

The name used in the SQL Server to reference the file. The name must be unique in the server. @name is nvarchar(260), with no default.

[ @filename = ] N'os_file_name'

The path and file name used by the operating system for the file. The file must reside on an instance of the Database Engine. @filename is nvarchar(260), with no default.

[ @size = ] N'size'

The initial size of the file. @size is nvarchar(20), with a default of NULL. Specify a whole number; don't include a decimal. The MB and KB suffixes can be used to specify megabytes or kilobytes. The default is MB. The minimum value is 512 KB. If @size isn't specified, the default is 1 MB.

[ @maxsize = ] N'max_size'

The maximum size to which the file can grow. @maxsize is nvarchar(20), with a default of NULL. Specify a whole number; don't include a decimal. The MB and KB suffixes can be used to specify megabytes or kilobytes. The default is MB.

If @maxsize isn't specified, the file grows until the disk is full. The Windows application log warns an administrator when a disk is about to become full.

[ @filegrowth = ] N'growth_increment'

The amount of space added to the file each time new space is required. @filegrowth is nvarchar(20), with a default of NULL. A value of 0 indicates no growth. Specify a whole number; don't include a decimal. The value can be specified in MB, KB, or percent (%). When % is specified, the growth increment is the specified percentage of the size of the file at the time the increment occurs. If a number is specified without an MB, KB, or % suffix, the default is MB.

If @filegrowth is NULL, the default value is 10%, and the minimum value is 64 KB. The size specified is rounded to the nearest 64 KB.

Return code values

0 (success) or 1 (failure).

Result set

None.

Examples

In the following example, the database db1 was marked suspect during recovery due to insufficient log space (error 9002).

EXEC sp_add_log_file_recover_suspect_db db1,
    logfile2,
    'C:\Program Files\Microsoft SQL
    Server\MSSQL13.MSSQLSERVER\MSSQL\Data\db1_logfile2.ldf',
