ALTIBASE JDBC DRIVER

If access to two different Altibase instances with different versions is required, both JDBC drivers must be loaded. I’ve created a small wrapper jinst. Altibase does not support the use of setObject parameterIndex,null. If maxpoolsize is set the default value is minpoolsize , and you try and reserve a connection and there aren’t any available, the pool will be grown. Sign up or log in Sign up using Google. Altibase DB name The following example shows how to obtain a connection object using the format outlined above:

Therefore, the use of executeBatch may improve performance by reducing the amount of communication required between the application server and the database server. The following example shows how to connect to disparate versions of Altibase using the Altibase.

Supported Java Versions 1. Second code is just using one connection for every query. The following Altibase manuals can also be used as references during altibade I’ve created a small wrapper jinst. Therefore, care should be taken to select an appropriate value that balances communication frequency and client memory utilization.

The communications buffer is 32K by default. Assume that there is a program that jcbc fetch bytes worth of data. The user should verify that the Altibase server is running if this error is encountered.

To call a database stored procedure from within an application, the callSQL statement can be used to obtain a CallableStatement object:. Each property can be configured either by using the java. I can’t reproduce your problem, I’m not even sure which connection pool you’re using. To use this function, data should be added to an array using the addBatch method and then executed algibase calling executeBatch.

Do I close the already closed connection? What does getConnection do? Therefore, it is preferably to configure setFetchSize to a value larger than the maximum number of records to fill the 32K communication buffer.

Using setFetchSize The setFetchSize method can be used to set the number of records to fetch at a time from the database server. Here is the sample codes. JDBC connections can then be acquired with the reserve function and returned to the pool with the release function.

This class is defined in the Altibase. Therefore, the PreparedStatement object can be used to improve performance if the SQL statement can be processed through binding-execute using variable parameters.

Failure to call the close method will result in these objects remaining in heap memory. This error occurs if altbase Altibase instance is currently not operational. IPC 1 The following examples show how to configure connection properties using the methods described above: All the tests work out of the box on a 1.

Returning Altigase After using Connection, Statement, or ResultSet objects, the relevant resources must be returned by explicitly calling the close method. If maxidle is a falsy value jcbc is absent from the config, this feature does not come into effect.
