SQL Server DBTUNE configuration parameters

SQL Server DBTUNE configuration parameters

Release 9.3 E-mail This TopicPrintable VersionGive Us feedback

NOTE: Applies to geodatabases created with an ArcGIS Server Enterprise license only

Configuration parameters, which are stored in the parameter_name column of the SDE_dbtune table, identify the database object to be configured or denote a specific setting. Their corresponding values, which are stored in the config_string column of SDE_dbtune, identify how the object or setting will be configured. The parameters and their configuration strings are grouped together in the SDE_dbtune table by configuration keywords. Keyword/Parameter_name combinations are unique, but most parameter_names are not and are reused under a number of different keywords throughout the SDE_dbtune table.

Valid values for the parameter_names column are fixed; you cannot invent new parameter_names. Likewise, the config_strings accept only certain numeric values or SQL strings. In most cases, these strings are appended to Transact-SQL CREATE TABLE and CREATE INDEX statements.

In geodatabases stored in SQL Server, DBTUNE parameters and their corresponding configuration strings are used by ArcSDE to identify the following:

There are a number of ways to categorize configuration parameters. Often times, a parameter fits into more than one category. For example, the B_CLUSTER_RASTER parameter can be categorized as a business table parameter, a raster parameter, or a clustered index parameter.

The following table is an alphabetic list of all the possible configuration parameters that can be used in a geodatabase in SQL Server. Following that is a more in-depth explanation of the parameters roughly grouped by related functionality.

Parameters specific to feature class and raster storage

Parameters specific to indexes

Parameters for storing text

Parameters that affect spatial storage

Spatial index parameters were discussed under the section "Parameters specific to indexes". Other parameters that affect spatial data storage are GEOMETRY_STORAGE and GEOM_SRID_CHECK.

Parameters for XML document storage

NOTE: If you do not use XML columns and XML documents in your geodatabase, you don't need to configure these parameters.

ArcSDE business tables that contain an SE_XML_TYPE column will employ two side tables to store the XML document and the content of individual elements in those documents that have been indexed.

If searches typically examine the entire content of XML documents to see if they contain specific words, or if you don't search XML documents at all, the XML document table will be more heavily used. XML document tables will have three parameters:

XML_DOC_INDEX
XML_DOC_STORAGE
XML_DOC_TEXT_IN_ROW

XML_DOC_STORAGE provides the storage string for the table's creation statement. XML_DOC_INDEX has the index fill factor and storage parameters, while XML_DOC_TEXT_IN_ROW pertains to storing BLOB data in line. See the following section "Text in row parameters" for more information.

If individual elements are frequently searched, the XML document index table will be the most heavily accessed of the XML tables. It has more SDE_dbtune parameters; they all begin with XML_IDX_.

XML_IDX_CLUSTER_DOUBLE
XML_IDX_CLUSTER_ID
XML_IDX_CLUSTER_PK
XML_IDX_CLUSTER_TAG
XML_IDX_INDEX_DOUBLE
XML_IDX_INDEX_ID
XML_IDX_INDEX_PK
XML_IDX_INDEX_TAG
XML_IDX_STORAGE
XML_IDX_TEXT_IN_ROW

The XML_IDX_CLUSTER_* parameters dictate which index of the XML document index table should be clustered. By default, the primary key's index (on the xml_key_column) is clustered.

The following parameters affect both the XML document table and the XML document index table for an XML column. They control how and when the document content is indexed.

XML_IDX_FULLTEXT_CAT
XML_IDX_FULLTEXT_LANGUAGE
XML_IDX_FULLTEXT_TIMESTAMP
XML_IDX_FULLTEXT_UPDATE_METHOD

XML_IDX_FULLTEXT_CAT contains the name of the full-text catalog you created. The default is SDE_DEFAULT_CAT. If you name your full text catalog something other than SDE_DEFAULT_CAT, you must update the config_string for this parameter.

XML_IDX_FULLTEXT_LANGUAGE represents the language to be used for linguistic analysis when building the text indexes on the XML document's content. A default value is not provided; therefore, the language defined in SQL Server's default full-text language setting is used. If a value is provided, this language will be used for linguistic analysis instead.

XML_IDX_FULLTEXT_TIMESTAMP and XML_IDX_FULLTEXT_UPDATE_METHOD control full text index maintenance. The update_method parameter dictates how changes made to the document table are propagated to the full text index. The time stamp parameter, by default (1), will add a time stamp column to the SDE_xml_idx<xml_column_id> table. If set to 0, no such column is added.

If update_method is set to 0 and time stamp is set to 0, no index maintenance is performed, and whenever ArcSDE is instructed to update the full-text index (through SE_xmlindex_update_text_index), the index will be fully populated.

If update_method is set to 0 and time stamp is set to 1, no index maintenance is performed, and ArcSDE will perform an incremental index population of whatever has changed since the last incremental update.

If update_method is set to CHANGE_TRACKING MANUAL, the database maintains a list of changed rows but does not update the index.

If update_method is set to CHANGE_TRACKING BACKGROUND, the database tracks changes and automatically updates the index.

It is recommended that you use the default settings provided in the SDE_dbtune table. If your server is unable to service its workload and your only recourse is to change indexing behavior, set change tracking to manual (CHANGE_TRACKING MANUAL).

The next parameters, XML_IDX_INDEX_*, control index fill factor and storage on the SDE_xml_idx<xml_column_id> table. The XML_IDX_TEXT_IN_ROW, controls how much of the XML document BLOB can be in-line. As with most text in row settings, it is recommended that you do not change the defaults. See Configuring a SQL Server database to support XML columns for more information on the XML_IDX_FULLTEXT_CAT, XML_IDX_FULLTEXT_LANGUAGE, and XML_IDX_FULLTEXT_UPDATE_METHOD parameters.

Parameters that affect ArcSDE log file tables and indexes

Log file tables are used by ArcSDE to maintain temporary and persistent sets of selected records.

Log file parameters affect log file data tables and indexes. Most of these parameters begin with the letter L. The parameters are as follows:


Parameter Description
LD_INDEX_ALL Defines SDE_logfile_data and SDE_logpool tables primary key storage
LD_STORAGE Defines configuration for the SDE_logfile_data and SDE_logpool_<sde_id> tables
LF_CLUSTER_ID The index type for SDE_logfiles primary key
LF_CLUSTER_NAME The index type for unique index on the log file_name column of the SDE_logfiles table.
LF_INDEX_ID Defines SDE_logfiles primary key storage.
LF_INDEX_NAME Defines storage for the SDE_logfiles unique index.
LF_STORAGE Defines the configuration for the SDE_logfiles table
SESSION_TEMP_TABLE Controls whether or not session and stand-alone log file tables are created in the tempdb database. By default, it is set to 1, meaning session and stand-alone log files are created in tempdb.

Creating session log file tables in the tempdb database is the recommended log file configuration for SQL Server. No special CREATE TABLE permission is required because every login has permission to create objects in tempdb. Having log file tables as temporary tables offloads the burden placed on the transaction log to the tempdb database. Tempdb logs transactions against tables more efficiently than regular databases do because its transaction log is only required for rolling back transactions and not for recovery. Because temporary tables are deleted when their session disconnects, there is no permanent overhead associated with their storage.

If you have several active ArcSDE instances, they may all be using tempdb for log files. While you can configure each instance to use log files differently, you should watch tempdb activity to see if the database becomes hot and causes an I/O bottleneck. The tempdb database can be easily moved to a different disk volume and does not need to be managed for recovery in the same way that other databases are; for instance, it does not need to live on a RAID volume. See SQL Server Books Online for more information on managing the tempdb database.

For information on ArcSDE log file tables, see Log file configuration options.

Some parameters don't fit well in a particular category. These are described in this section.
