![]() ![]() In the Properties pane, in the Advanced section, set StringStoresCompatibilityLevel to 1100. In Dimension Designer, in the Attributes pane, make sure that the parent node of the dimension is selected (for example, if the dimension is Customers, select Customers and not one of the child attributes). Double-click the dimension for which you are modifying string storage. ![]() To change the string storage for dimensions, open Solution Explorer. Using SQL Server Data Tools, open the project that contains the dimensions or partitions you want to modify. Step 1: Set the StringStoreCompatiblityLevel Property in SQL Server Data Tools For more information, see Compatibility Level of a Multidimensional Database (Analysis Services). For databases that you are moving, but not redeploying, you can use SQL Server Management Studio to set the compatibility level. If you moved a database created in an earlier version of SQL Server Analysis Services to ssSQL11 or later, you must update the compatibility level. If you created or deployed a database using SQL Server Data Tools and the SQL Server 2012 (11.x) or later version of SQL Server Analysis Services, the database compatibility level is already set to 1100. The database compatibility level must be set to 1100. You must have a SQL Server 2012 (11.x) or later version of SQL Server Analysis Services.ĭimensions and partitions must use MOLAP storage. If you have very long strings that do not fit in a single record, your effective limit will be less than 4 billion strings. Larger string storage creates records of an even size, where each record is equal to a 64K page. The maximum limit for larger string storage is 4 billion unique strings or 4 billion records, whichever occurs first. In contrast with the default string storage architecture which limits the size of the physical file, larger string storage is based on a maximum number of strings. In SQL Server 2012 (11.x), you can override the maximum file size by specifying an alternative storage mechanism that allows a string store to grow as needed. By default, each of these files is subject to a maximum 4 GB limit. You can identify a string store by its file extension (for example, asstore. It is also possible to have string data in distinct count measures. String data is typically found in dimension attributes that represent names or descriptions. In an Analysis Services multidimensional database, strings are stored separately from numeric data to allow for optimizations based on characteristics of the data. Currently, it is still possible to encounter the GB file size limitation on models containing data mining structures. This setting does not apply to data mining models. ![]() Specifies larger string storage, supports up to 4 billion unique strings per store. Specifies the default string storage architecture, subject to a 4 GB maximum file size per store. Valid values for this property include the following: Value Because the setting is for strings, numeric data is unaffected. However, partitions that contain distinct count measures on top of strings can also benefit from this setting. In most multidimensional models, string data is associated with dimensions. Note that you can increase string storage on just those objects that require additional capacity. If your dimensions or partitions include string stores of this size, you can work around the file size constraint by changing the StringStoresCompatibilityLevel property at the dimension or partition level, for local as well as linked (local or remote) objects. You can reconfigure string storage to accommodate very large strings in dimension attributes or partitions that exceed the 4 GB file size limit for string stores. ![]()
