Specifies the directory where collected data is stored before it's uploaded to the management data warehouse.
Transact-SQL syntax conventions
Syntax
sp_syscollector_set_cache_directory [ [ @cache_directory = ] N'cache_directory' ]
[ ; ]
The directory in the file system where collected data is stored temporarily. @cache_directory is nvarchar(255), with a default of an empty string. If no value is specified, the default temporary SQL Server directory is used.
Return code values
0 (success) or 1 (failure).
Remarks
You must disable the data collector before changing the cache directory configuration. This stored procedure fails if the data collector is enabled. For more information, see Enable or disable data collection, and Manage data collection.
The specified directory doesn't need to exist at the time the sp_syscollector_set_cache_directory is executed; however, data can't be successfully cached and uploaded until the directory is created. We recommend creating the directory before executing this stored procedure.
Permissions
Requires membership in the dc_admin (with EXECUTE permission) fixed database role to execute this procedure.
Examples
The following example disables the data collector, sets the cache directory for the data collector to D:\tempdata, and then enables the data collector.
USE msdb;
GO
EXECUTE dbo.sp_syscollector_disable_collector;
GO
EXEC dbo.sp_syscollector_set_cache_directory
@cache_directory = N'D:\tempdata';
GO
EXECUTE dbo.sp_syscollector_enable_collector;
GO
