| MaxLogFileCount | Specifies the maximum number of log files the provider retains. When the limit is reached, the oldest log file is deleted to make space for a new one. |
| Property | Description |
| Location | Specifies the location of a directory containing schema files that define tables, views, and stored procedures. Depending on your service's requirements, this may be expressed as either an absolute path or a relative path. |
| BrowsableSchemas | Optional setting that restricts the schemas reported to a subset of all available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC . |
| Tables | Optional setting that restricts the tables reported to a subset of all available tables. For example, Tables=TableA,TableB,TableC . |
| Views | Optional setting that restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC . |
| Property | Description |
| AutoCache | Specifies whether the content of tables targeted by SELECT queries is automatically cached to the specified cache database. |
| CacheProvider | The namespace of an ADO.NET provider. The specified provider is used as the target database for all caching operations. |
| CacheDriver | The driver class of a JDBC driver. The specified driver is used to connect to the target database for all caching operations. |
| CacheConnection | Specifies the connection string for the specified cache database. |
| CacheLocation | Specifies the path to the cache when caching to a file. |
| CacheTolerance | Notes the tolerance, in seconds, for stale data in the specified cache database. Requires AutoCache to be set to True. |
| Offline | Gets the data from the specified cache database instead of live DB2 data. |
| CacheMetadata | Determines whether the provider caches table metadata to a file-based cache database. |
| Property | Description |
| AllowPreparedStatement | Prepare a query statement before its execution. |
| CharBitDataAsString | A Boolean value used to indicate whether parameters, result data, and schema information for iDB2CharBitData and iDB2VarCharBitData objects are treated as String values or as Byte array values. |
| CharBitDataCcsid | An Int32 value used to indicate which CCSID is used to translate iDB2CharBitData and iDB2VarCharBitData types when the CharBitDataAsString property is set to true. This property is ignored when CharBitDataAsString is set to false. |
| TruncateString | This property specifies whether to truncate characters when INSERT or UPDATE is executed with a string that exceeds the column size. |
| Schema | The schema used by default. |
| BatchSize | Specifies the maximum number of rows included in each batch submitted during batch operations. To submit the entire batch as a single request, set BatchSize to 0 . |
| ConnectOnOpen | Specifies whether the provider establishes a connection to DB2 immediately upon opening the connection. Set ConnectOnOpen to True if immediate connectivity verification is necessary. |
| DefaultDomain | This property is used for the Oracle Database Gateway for ODBC. |
| EnableForeignKeyDetection | Whether to detect the foreign keys in ODBC. |
| IgnoreCase | Specifies whether to ignore case in SQL identifiers. |
| IncludeDualTable | Set this property to mock the Oracle DUAL table for better compatibility with Oracle database. |
| LimitKeySize | The maximum length of a primary key column. |
| MapBigintToVarchar | This property controls whether or not the bigint type maps to SQL_VARCHAR instead of SQL_BIGINT. This property is false by default. |
| MapToInt | This property controls whether or not the long type maps to SQL_INTEGER instead of SQL_BIGINT. This property is false by default. |
| MapToLongVarchar | This property controls whether or not a column is returned as SQL_LONGVARCHAR. |
| MapToWVarchar | This property controls whether or not string types map to SQL_WVARCHAR instead of SQL_VARCHAR. This property is set by default. |
| MaximumColumnSize | The maximum column size. |
| MaxRows | Specifies the maximum number of rows returned for queries that do not include either aggregation or GROUP BY. |
| Other | Specifies additional hidden properties for specific use cases., to be used only when our Support team advises it, to address specific issues. See Remarks for details. |

| Timeout | Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error. |
| UpperCaseIdentifiers | This property reports all identifiers in uppercase. This is the default for Oracle databases and thus allows better integration with Oracle tools such as the Oracle Database Gateway. |
