The initial connection may take a few minutes because of the number and size of the packages that must be created for the connection. The default is 1. You will not be able to connect to the mainframe with any redistributable JDBC driver. IPv6 addresses are only supported when connecting to certain database versions as shown in Table If 1, the driver describes the data types using JDBC 3. DB2 defines its own encryption protocol for these databases. The ClientProgramName will become the correlation id, which you will probably find easily in the Omegamon Performance Warehouse tables.

Permissions for Kerberos Authentication To use Kerberos thpe4 with the Oracle Type 4 JDBC drivers that support it, the application and driver code bases must be granted security permissions in the security policy file of the Java 2 Platform as shown in the following examples.
Consider the following information if your application requires DB2 packages with a large number of dynamic sections: If an fb2 is generated as a result of restoring the state of work in progress, the driver type44 with the failover process, but generates an exception warning that the Select statement must be reissued. Consult with your database administrator to ensure that you have the correct privileges. String By default, the driver automatically determines which code page to use to convert Character data.
For a list of connection properties and their valid values, see DB2 Connection Properties. If the size of the result set data exceeds the buffer size, the driver pages the result set data to disk.
Powerful IBM DB2 JDBC Driver
If the value set for this property is greater than the number of prepared statements that are used by the application, all prepared statements that are created by the application are cached.
Each SQLException contains the type44 information:.
Determines the amount of memory used by the driver to cache insensitive result set data. The following Select statements show further examples for which parameter metadata can be returned: For example, the following command requests a TGT from the server with a lifetime of 10 hours, which is renewable for 5 days:. Restricting results to the tables and views in the current schema improves the performance of calls for getTables methods that do not specify a schema.
Type 2 drivers tpe4 a native code component, like a DLL or a shared library.
DB2 JDBC Driver and URL Information
Setting MaxPooledStatements to an integer greater than zero 0 enables the driver’s internal prepared statement pooling, which is useful when the driver is not running from within an application server or another application that provides its own prepared statement pooling. If any one validation succeeds, a connection is established.
As the number of open sections increases, so does the likelihood that a deadlock situation may occur. The database server relies on the client to authenticate the user and does not provide additional authentication. For example, if your application calls Statement. All connection property names are ty;e4. If falsethe driver uses the batch mechanism for batch inserts.
hype4 This property is useful when individual keys in the keystore file have a different password than the keystore file. When the driver’s internal prepared statement pooling is enabled, the driver caches a certain number of prepared statements created by an application.
Using Oracle Type 4 JDBC Drivers
You can get the drivers from the IBM site. The default isolation level dh2 Read Committed. Determines whether a cancel request sent by the driver as the result of a query timing out is subject to the same query timeout value as the statement it cancels. If truethe cancel request times out using the same timeout value, in seconds, that is set for the statement it cancels. For example, given a database table defined as:.
To use insensitive scrollable cursors or to perform client-side sorting of DatabaseMetaData result sets, all code bases must have access to temporary files. The statement contains a predicate value expression part that is rb2 nested query. The following query is an example of a Select statement that returns a result set that contains a generated column the column named “upper”.
Parameter metadata can be returned for a Select statement if one of the following conditions is true: To minimize this hang time, you can specify a LoginTimeout value for the connection. If this property is not specified, the truststore password is specified by the javax.
Truststore information is specified using the TrustStore and TrustStorePassword properties or by using Java system properties.
