Oracle oci8 jdbc driver

To enable or disable connect-time failover for multiple protocol addresses. Supported values on off. To enable or disable client load balancing for multiple protocol addresses. To instruct JavaNet to optimize the transfer rate of data packets being sent across the network with a specified session data unit SDU size in bytes.

The default value is 0. To specify the delay in seconds between subsequent retries for a connection. To specify the value of service tag. While establishing connection to the Oracle Database, the configured value is sent as part of connect data. Use this parameter to specify if an application needs a new session that is not tainted with any prior session state or to reuse a previous session. Specifies the location of the wallet file.

More Info.. Use this to specify the set of cipher suites to be used while SSL protocol negotiation. To specify the timeout duration in seconds for a client to establish an Oracle Net session to an Oracle database.

To specify the transportation timeout duration in seconds for a client to establish an network connection to an Oracle Database. Specifies the encryption level supported by client. Supported values are accepted rejected requested required More Info.. Specifies the list of encryption algorithms supported by client. Specifies the data integrity level supported by client. Specifies the list of data integrity algorithms supported by client. Use this property to specify the wallet location.

If you do not explicitly close your ResultSet and Statement objects, serious memory leaks could occur. You could also run out of cursors in the database.

Closing a result set or statement releases the corresponding cursor in the database. For example, if your ResultSet object is rset and your Statement object is stmt , close the result set and statement with these lines:. When you close a Statement object that a given Connection object creates, the connection itself remains open.

Note: Typically, you should put close statements in a finally clause. This allows you to execute a statement with varying sets of input parameters. Use setXXX methods on the PreparedStatement object to bind data into the prepared statement to be sent to the database. Note that there is nothing Oracle-specific about the functionality described here; it follows standard JDBC syntax.

This is known as auto-commit mode. You can, however, disable auto-commit mode with the following method call on the Connection object:. For further discussion of auto-commit mode and an example of disabling it, see "Disabling Auto-Commit Mode". If you disable auto-commit mode, then you must manually commit or roll back changes with the appropriate method call on the Connection object:.

Important: If auto-commit mode is disabled and you close the connection without explicitly committing or rolling back your last changes, then an implicit COMMIT operation is executed.

Close the Connection You must close your connection to the database once you finish your work. Use the close method of the Connection object to do this:. Import Packages Regardless of which Oracle JDBC driver you use, include the following import statements at the beginning of your program java. However, they are not required for the example presented in this section: import oracle. Notes: With JDK 1.

For example, batching doesn't seem to buy much in terms of performance. We've learned that subtle differences in the code can make big differences in performance. We've also learned that performance improvements are not "one size fits all". Thanks for the time and effort. Tom once again excellent answer.

I mean specifying all the TNS failover configuration in the Java program itself. Thanks Sami. October 05, - pm UTC. TAF requires the thick drivers. We are still checking the logic of our codes, but it may hit JDBC bug on 8. As a workaround, we would like to try 9. From my reasearch, some shops are running 9.

My question is: 9. Is is supported? May 11, - pm UTC. JDBC 9. Tom, We tried 9. I know from the following java thread dump that the deadlock is happening because two threads are accesing the same Connection and ResultSet object. We are still investigating our design. I need some help on how JDBC behave. I know that when commit is called the JDBC driver will lock the connection and loop through to lock all statements associated with that connection.

Could you help on the following questions: 1 In addition to commit in what condition does JDBC lock both connection and statement see the following thread dump? Can I assume that there is an implicit commit following the executeQuery? If not, what else could cause JDBC to lock both connection and statement? ReqManager": at oracle.

ScrollableResultSet at oracle. T4CConnection at abc. SubTermReqMgr": at oracle. T4CConnection at Oracle. OracleResultSetImpl at oracle. ScrollableResultSet at abc. Found 1 deadlock. Thanks again!! May 20, - am UTC. However, this method is valid only for JDK-compliant Java virtual machines.

It is not valid for Microsoft Java virtual machines. Once you have registered the driver, you can open a connection to the database with the static getConnection method of the java. The type of the object returned is java. The following example connects user scott with password tiger to a database with SID orcl through port of host myhost , using the Thin driver. The following example connects user scott with password tiger to a database on host myhost using the OCI driver.

In this case, however, the URL includes the userid and password, and is the only input parameter. If you want to connect with the Thin driver, you must specify the port number and SID.
