WebLogic Type 4 JDBC Drivers
The following sections describe how to configure and use the BEA WebLogic Type 4 JDBC driver for DB2:
The BEA WebLogic Type 4 JDBC driver for DB2 (the 'DB2 driver') supports:
- DB2 Universal Database (UDB) 7.1, 7.2, and 8.1 on Windows NT, Windows 2000, Windows 2003, Windows XP, UNIX, Linux, and Linux/s390 via DRDA
- DB2 6.1 and DB2 UDB 7.1 running on OS/390 and z/OS via DRDA
- DB2 UDB V4R5, V5R1, and V5R2 running on iSeries and AS/400
Note: This documentation uses the following terms to describe the different DB2 versions:
- 'DB2 UDB' refers to all versions of DB2 running on Windows, UNIX, and Linux/s390 platforms
- 'DB2 OS/390' refers to all versions of DB2 on OS/390 and z/OS platforms
- 'DB2 iSeries' refers to all versions of DB2 on iSeries and AS/400
The driver class for the BEA WebLogic Type 4 JDBC DB2 driver is:
XA: weblogic.jdbcx.db2.DB2DataSource
Non-XA: weblogic.jdbc.db2.DB2Driver
Use these driver classes when configuring a JDBC data source in your WebLogic Server domain.
To connect to a DB2 database, use the appropriate URL format:
- DB2 on Windows NT, Windows 2000, Windows 2003, Windows XP, UNIX, Linux, and Linux/s3901:
- DB2 on OS/390, z/OS, iSeries, and AS/4001:
Table 3-1 lists the JDBC connection properties supported by the DB2 driver, and describes each property. You can use these connection properties in a JDBC data source configuration in your WebLogic Server domain. To specify a property, use the following form in the JDBC data source configuration:
Note: All connection property names are case-insensitive. For example, Password is the same as password.
Table 3-1 DB2 Connection Properties
Property | Description |
|---|---|
AddToCreateTable OPTIONAL | A string that is automatically added to all Create Table statements. This field is primarily for users who need to add an 'in database' clause. |
AllowImplicitResultSetCloseForXA OPTIONAL | {true false}. DB2 provides a mechanism that automatically closes a result set when all rows of the result set have been fetched. This mechanism increases application performance by reducing the number of database round trips. The WebLogic DB2 driver uses this mechanism by default. Note: Problems have been noted when using this mechanism. As a workaround, you should add The default is true. |
AlternateID OPTIONAL | Sets the default DB2 schema used by unqualified SQL identifiers to the specified value. The value must be a valid DB2 schema. |
BatchPerformanceWorkaround OPTIONAL | {true false}. For DB2 UDB 8.1, the native DB2 batch mechanism is used. This property determines whether certain restrictions are enforced to facilitate data conversions.
The default is false. See Performance Workaround for Batch Inserts and Updates for more information. Note: For data sources used as a JMS JDBC store that use the WebLogic Type 4 JDBC driver for DB2, the |
CatalogIncludesSynonyms OPTIONAL | {true false}. When set to The default is |
CatalogSchema OPTIONAL | The DB2 schema to use for catalog functions. The value must be the name of a valid DB2 schema. The default is SYSCAT for DB2 UDB, SYSIBM for DB2 OS/390, and QSYS2 for DB2 iSeries. To improve performance, views of system catalog tables can be created in a schema other than the default catalog schema. Setting this property to a schema that contains views of the catalog tables allows the driver to use those views. To ensure that catalog methods function correctly, views for specific catalog tables must exist in the specified schema. The views that are required depend on your DB2 database. See Using a Non-Default Schema for Catalog Methods for the required views of catalog tables. |
CharsetFor65535 OPTIONAL | The code page to use to convert character data stored as bit data in character columns (Char, Varchar, Longvarchar, Char for Bit Data, Varchar for Bit Data, Longvarchar for Bit Data) defined with CCSID 65535. All character data stored as bit data retrieved from the database using columns defined with CCSID 65535 is converted using the specified code page. The value must be a string containing the name of a valid code page supported by your Java Virtual Machine, for example, CharsetFor65535=CP950. This property has no effect when writing data to character columns defined with CCSID 65535. |
CodePageOverride OPTIONAL | A code page to be used to convert Character and Clob data. The specified code page overrides the default database code page. All Character and Clob data retrieved from or written to the database is converted using the specified code page. The value must be a string containing the name of a valid code page supported by your Java Virtual Machine, for example, CodePageOverride=CP950. |
CollectionId OPTIONAL | The collection (group of packages) to which the package is bound. This property is ignored for DB2 UDB. The default is NULLID. |
ConnectionRetryCount OPTIONAL | The number of times the driver retries connection attempts until a successful connection is established. Valid values are 0 and any positive integer. If set to 0, the driver does not retry connections if a successful connection is not established on the driver's first attempt to create a connection. The default is 0. |
ConnectionRetryDelay OPTIONAL | The number of seconds the driver will wait between connection retry attempts when ConnectionRetryCount is set to a positive integer. The default is 3. |
CreateDefaultPackage OPTIONAL | {true false}. Determines whether the default package should be created. For DB2 OS/390 and DB2 iSeries, the package is created in the collection specified by the CollectionId property. This would be used if the package does not yet exist. For more information about creating DB2 packages, see Creating a DB2 Package.
The default is false. |
DatabaseName | The name of the database to which you want to connect (used with UDB). |
DynamicSections OPTIONAL | Specifies the number of statements that the DB2 driver package can prepare for a single user. The default is 200. |
Grantee OPTIONAL | Specifies the name of the schema to which you want to grant EXECUTE privileges for DB2 packages. This property is ignored if the GrantExecute property is set to false. See Creating a DB2 Package for more information about creating DB2 packages. The default is PUBLIC. |
GrantExecute OPTIONAL | {true false}. Determines whether EXECUTE privileges for DB2 packages are granted to a schema other than the one used to create them. If set to true, EXECUTE privileges are granted to the schema specified by the Grantee property. If set to false, EXECUTE privileges are not granted to another schema. See Creating a DB2 Package for more information about creating DB2 packages. The default is true. |
InsensitiveResultSetBufferSize | {-1 0 x}. Determines the amount of memory used by the driver to cache insensitive result set data. It must have one of the following values: If set to -1, the driver caches all insensitive result set data in memory. If the size of the result set exceeds available memory, an OutOfMemoryException is generated. Because the need to write result set data to disk is eliminated, the driver processes the data more efficiently. If set to 0, the driver caches all insensitive result set data in memory, up to a maximum of 2 GB. If the size of the result set data exceeds available memory, the driver pages the result set data to disk. Because result set data may be written to disk, the driver may have to reformat the data to write it correctly to disk. If set to x, where x is a positive integer that specifies the size (in KB) of the memory buffer used to cache insensitive result set data. If the size of the result set data exceeds the buffer size, the driver pages the result set data to disk. Because the result set data may be written to disk, the driver may have to reformat the data to write it correctly to disk. Specifying a buffer size that is a power of 2 results in more efficient memory use. The default is 2048 (KB) |
LocationName | The name of the DB2 location that you want to access (used with OS/390 and iSeries). |
LoginTimeout OPTIONAL | The maximum time in seconds that attempts to create a database connection will wait. A value of |
PackageOwner OPTIONAL | Specifies the owner of DB2 packages. See Creating a DB2 Package for more information about creating DB2 packages. The default is NULL. |
Password | A case-sensitive password used to connect to your DB2 database. A password is required only if security is enabled on your database. If so, contact your system administrator to get your password. |
PortNumber OPTIONAL | The TCP port on which the database server listens for connections. The default is 50000. |
ReplacePackage OPTIONAL | {true false}. Specifies whether the current bind process should replace an existing DB2 package. On DB2 UDB, this property must be used in conjunction with CreateDefaultPackage. For more information about creating DB2 packages, see Creating a DB2 Package. The default is false. |
SecurityMechanism OPTIONAL | {ClearText EncryptedPassword EncryptedUIDPassword}. Determines the security method the driver uses to authenticate the user to the DB2 server when establishing a connection. If the specified authentication method is not supported by the DB2 server, the connection fails and the driver generates an exception. If set to ClearText, the driver sends the password in clear text to the DB2 server for authentication. If set to EncryptedPassword, the driver sends an encrypted password to the DB2 server for authentication. If set to EncryptedUIDPassword, the driver sends an encrypted user ID and password to the DB2 server for authentication. The default is ClearText. Requires JDK 1.4 or higher. |
SendStreamAsBlob OPTIONAL | {true false}. Determines whether binary stream data that is less than 32K bytes is sent to the database as Long Varchar for Bit Data or Blob data. Binary stream data that is less than 32K bytes can be inserted into a Long Varchar for Bit Data column, which has a maximum length of 32K bytes, or a Blob column. Binary streams that are larger than 32K bytes can only be inserted into a Blob column. The driver always sends binary stream data larger than 32K bytes to the database as Blob data. If set to true, the driver sends binary stream data that is less than 32K to the database as Blob data. If the target column is a Long Varchar for Bit Data column and not a Blob column, the Insert or Update statement fails. The driver automatically retries the Insert or Update statement, sending the data as Long Varchar for Bit Data, if the stream passed into the driver is resettable. Sending binary stream data that is less than 32K bytes in length initially as a Blob significantly improves performance if the Insert or Update column is a Blob column. If set to false, the driver sends binary stream data that is less than 32K to the database as Long Varchar for Bit Data data. If the target column is a Blob column and not a Long Varchar for Bit Data column, the Insert or Update statement fails. The driver retries the Insert or Update statement, sending the data as Blob data. The default is false. |
ServerName | The name or IP address of the database server. |
StripNewlines OPTIONAL | {true false}. Specifies whether new-line characters in a SQL statement are sent to the DB2 server. When StripNewlines=true, the DB2 driver removes all new-line characters from SQL statements. The default is true. |
UseCurrentSchema OPTIONAL | {true false}. Specifies whether results are restricted to the tables in the current schema if a DatabaseMetaData.getTables call is called without specifying a schema or if the schema is specified as the wildcard character %. Restricting results to the tables in the current schema improves the performance of calls for getTables methods that do not specify a schema. If set to true, results that are returned from the getTables method are restricted to tables in the current schema. If set to false, results of the getTables method are not restricted. The default is false. |
User | The case-sensitive user name used to connect to your DB2 database. |
WithHoldCursors OPTIONAL | {true false}. Determines whether the cursor stays open on commit—either DB2 closes all open cursors (Delete cursors) after a commit or leaves them open (Preserve cursors). If set to true, the cursor behavior is Preserve. If set to false, the cursor behavior is Delete. Rolling back a transaction closes all cursors regardless of how this property is specified. The default is true. |
When connecting to a DB2 database running on AS/400, you must set the locationName property:
- Obtain the 'Relational Database' value by executing the
WRKRDBDIREcommand on AS/400. You should see output similar to the following:
- In the Java client, set up the
Propertiesobject with 'user' and 'password' DB2 connection properties (see DB2 Connection Properties). - In
Driver.connect(), specify the following string and the Properties object as parameters: In this example,
RelationalDatabaseNameis the value ofDatabaseobtained from the result of running theWRKRDBDIREcommand.
The following is an excerpt of the Java client :
A DB2 package is a control structure on the DB2 server produced during program preparation that is used to execute SQL statements. The DB2 driver automatically creates all DB2 packages required at connection time. If a package already exists, the driver uses the existing package to establish a connection.
Note: The initial connection may take a few minutes because of the number and size of the packages that must be created for the connection. Subsequent connections do not incur this delay.
By default, DB2 packages created by the DB2 driver contain 200 dynamic sections and are created in the NULLID collection (or library). In most cases, you do not need to create DB2 packages because the DB2 driver automatically creates them at connection time. If required, you can create DB2 packages in either of the following ways:
- Manually force the DB2 driver to create a package using the WebLogic Server
dbpingutility. See Creating a DB2 Package Using dbping. - Automatically create a package by setting specific connection properties in the connection URL. See Creating a DB2 Package Using Connection Properties.
Download Db2 Driver Windows 10
Note: Your user ID must have CREATE PACKAGE privileges on the database, or your database administrator must create packages for you.
Your user ID (the user ID listed in the JDBC data source configuration) must be the owner of the package.
The user ID creating the DB2 packages must have BINDADD privileges on the database. Consult with your database administrator to ensure that you have the correct privileges.
Creating a DB2 Package Using dbping
To create a package on the DB2 server with the WebLogic Type 4 JDBC DB2 driver, you can use the WebLogic Server dbping utility. The dbping utility is used to test the connection between your client machine and a DBMS via a JDBC driver. Because the WebLogic Type 4 JDBC DB2 driver automatically creates a DB2 package if one does not already exist, running this utility creates a default DB2 package on the DB2 server.
For details about using the dbping utility to create a DB2 package, see Creating a DB2 Package with dbping.
Creating a DB2 Package Using Connection Properties
You can create a DB2 package automatically by specifying specific connection properties in the initial connection URL. Table 3-2 lists the connection properties you should use in your initial connection URL when you create a DB2 package:
Note: This method is not recommended for use with WebLogic Server JDBC data sources because every connection in the data source uses the same URL and connection properties. When a JDBC data source with multiple connections is created, the package would be recreated when each database connection is created.
It is new and the most reliable software available in the market. The interface is simple yet very powerful and gives you access to all the features and tools offered by this software. It is very easy to use software with a simple interface. Drivermax full version free download.

|---|---|
| DB2 OS/390 and iSeries |
| DB2 UDB, OS/390, and iSeries |
| DB2 UDB |
| DB2 UDB, OS/390, and iSeries |
Using CreateDefaultPackage=TRUE creates a package with a default name. If you use CreateDefaultPackage=TRUE, and you do not specify a CollectionId, the NULLID CollectionId is created.
Note: On DB2 UDB, you must use ReplacePackage=TRUE in conjunction with CreateDefaultPackage to create a new package; however, if a package already exists, it will be replaced when using ReplacePackage=TRUE.
Example for DB2 UDB:
The following URL creates DB2 packages with 400 dynamic sections. If any DB2 packages already exist, they will be replaced by the new ones being created.
Example for DB2 OS/390 and iSeries:
The following URL creates DB2 packages with 400 dynamic sections.
Notes About Increasing Dynamic Sections in the DB2 Package
A dynamic section is the actual executable object that contains the logic needed to satisfy a dynamic SQL request. These sections are used for handles and prepared statements and the associated result sets.
In some cases, you may need to create DB2 packages with more than the default number of dynamic sections (200). Consider the following information if your application requires DB2 packages with a large number of dynamic sections:
- Creating DB2 packages with a large number of dynamic sections may exhaust certain server resources. In particular, you may need to increase the database parameter
PCKCACHE_SZto allow the larger packages to be created. - The creation of more dynamic sections will slow down the initial creation of the DB2 package.
- Using DB2 packages with a large number of dynamic sections may impact application performance. If a small number of sections are in use at one time, there will be no impact on the application. If a large number of sections are in use at one time, the performance of the application may decrease because the database will expend resources to check all open sections for locks.
- As the number of open sections increases, so does the likelihood that a deadlock situation may occur.
- If your application is mostly executing select statements, it is best to operate in the default mode of automatically committing the database. Dynamic sections are not freed in the DB2 package until the database is committed even if the statements are closed in the application. In this mode the database will commit every time a SQL statement is executed and free all of the sections that were opened. If you need to operate in a manual commit mode, then it is advisable to commit the database as often as possible to ensure that all server resources are freed in a timely manner.
- Statements cached in the WebLogic Server prepared statement cache will keep sections in use so that the prepared statements can be reused.
- The DB2 server has a limit on dynamic sections. It is possible to try to create more sections than the server will allow you to create.

4. Rowid data type is supported only for DB2 OS/390 and DB2 iSeries V5R2.
See GetTypeInfo for more information about data types.
To improve performance, views of system catalog tables can be created in a schema other than the default catalog schema. Setting the CatalogSchema property to a DB2 schema that contains views of catalog tables allows the driver to use those views. To ensure that catalog methods function correctly, views for the catalog tables listed in Table 3-4 must exist in the specified schema. The views that are required depend on your DB2 database.

DB2 OS/390 | SYSIBM.SYSTABCONST |
DB2 iSeries | QSYS2.SYSCST |
See SQL Escape Sequences for JDBC for information about SQL escape sequences supported by the DB2 driver.
The DB2 driver supports the isolation levels listed in Table 3-5. JDBC isolation levels are mapped to the appropriate DB2 transaction isolation levels as shown. The default isolation level is Read Committed.
Table 3-5 Supported Isolation Levels
JDBC Isolation Level | DB2 Isolation Level |
None | No Commit1 |
Read Committed | Cursor Stability |
Read Uncommitted | Uncommitted Read |
Repeatable Read | Read Stability |
Serializable | Repeatable Read |
1. Supported for DB2 iSeries versions that do not enable journaling.
The DB2 driver supports scroll-insensitive result sets and updatable result sets.
Note: When the DB2 driver cannot support the requested result set type or concurrency, it automatically downgrades the cursor and generates one or more SQLWarnings with detailed information.
To use JDBC distributed transactions through JTA with the DB2 driver, DB2 UDB 8.1 is required.
Retrieving and updating Blobs is supported by the DB2 driver only with DB2 UDB 8.1, DB2 OS/390, and DB2 iSeries V5R2.
Retrieving and updating Clobs is supported by the DB2 driver. The DB2 driver supports Clobs up to a maximum of 2 GB with DB2 UDB 8.1, DB2 OS/390, and DB2 iSeries V5R2; it supports Clobs up to a maximum of 32 KB with all other supported DB2 database versions.
Retrieving and updating DBClobs is supported by the DB2 driver only with DB2 UDB 8.1, DB2 OS/390 7.x, and DB2 iSeries V5R2.
For DB2 UDB 8.1 and DB2 OS/390, the DB2 driver uses the native DB2 batch mechanism. By default, the methods used to set the parameter values of a batch performed using a PreparedStatement must match the database data type of the column with which the parameter is associated.
DB2 servers do not perform any implicit data conversions, so specifying parameter values that do not match the column data type causes the DB2 server to generate an error. For example, to set the value of a Blob parameter using a stream or byte array when the length of the stream or array is less than 32K, you must use the setObject method and specify the target JDBC type as BLOB; you cannot use setBinaryStream or setBytes methods.
To remove the method-type restriction, set the BatchPeformanceWorkaround connection property to true (see DB2 Connection Properties). For example, you can use the setBinaryStream or setBytes methods to set the value of a Blob parameter regardless of the length of the stream or array; however, the parameter sets may not be executed in the order they were specified.
Notes: When you create a data source in the Administration Console, the Administration Console sets the BatchPeformanceWorkaround connection property to true by default.
For data sources used as a JMS JDBC store that use the WebLogic Type 4 JDBC driver for DB2, the BatchPerformanceWorkaround property must be set to true.
The DB2 driver supports returning parameter metadata for all statements with DB2 UDB 8.1, DB2 OS/390, and DB2 iSeries V5R2.
For all other supported DB2 database versions, the DB2 driver supports returning parameter metadata for the following forms of SQL:
INSERT INTO foo VALUES (?, ?, ?)INSERT INTO foo (col1, col2, col3) VALUES (?, ?, ?)UPDATE foo SET col1=?, col2=?, col3=? WHERE col1operator? [{AND OR} col2operator?]
where operator is any of the following SQL operators: =, <, >, <=, >=, and <>.
The DB2 driver supports retrieving the values of auto-generated keys. An auto-generated key returned by the DB2 driver is the value of an auto-increment column.
How you return those values depends on whether you are using an Insert statement that contains parameters:
- When using an Insert statement that does not contain any parameters, the DB2 driver supports the following form of the Statement.execute and Statement.executeUpdate methods to inform the driver to return the values of auto-generated keys:
Statement.execute (String sql, int autoGeneratedKeys)Statement.executeUpdate (String sql, int autoGeneratedKeys)- When using an Insert statement that contains parameters, the DB2 driver supports the following form of the Connection.prepareStatement method to inform the driver to return the values of auto-generated keys:
Connection.prepareStatement (String sql, int autoGeneratedKeys)
The application fetches the values of generated keys from the driver using the Statement.getGeneratedKeys method.
Due to a defect in DB2 servers, problems may occur when using a driver patch that is equal to, or greater than the patch levels above, if connecting to DB2 UDB on UNIX, Windows, or Linux where the server version is earlier than DB2 v8 FixPak 11. If you have connecton problems, you may need to include the following driver property in your configuration:
Use the following table to provide guidance on when to use ServerReleaseLevel:

Hi
We are working in a project where DB2 data from an IBM iSeries server (former AS400) is to be read from a Windows Server 2012 R2 64-bit machine with SQL Server 2016. The iSeries server is running on version 7.1 at the moment but will be upgraded to 7.3 in a couple of weeks.
I have tried various packages from IBM iAccess for Windows and IBM iAccess Client Solutions, but drivers for OLEDB, .NET or even ODBC is missing. We then tried the CliDriver-package in version 10.5 tested but we ended up with tests first resulting in VERY cryptic error messages, then landed in some sort of missing license message, even though the iSeries server is fully licensed for this.
We would appreciate some guide for downloading, installing and configuring a DB2 database driver for use in a Visual Studio 2015 SSIS package project.
Any input or tip is appreciated
Best Regards Peter Karlström
