JDBC

 

Connection Pools

   

General

     

Name

 

The user -defined name of the connection pool.

     

URL

 

This is the URL that you would use in a Java program to open a direct connection to the database.

     

Driver Classname

 

The full class name of the JDBC driver you want to use to access the data source.

     

Properties key=value

 

Use this field to enter various fields such as user, password, server, and so on. These key=value pairs (e.g., name=oracle) will be passed to the JDBC driver.

     

ACLName

 

Name of the access control list.

       

Password

The password specified in this field will override any password you may have specified in the Properties box as a name=value pair.

   

Connections

     

Initial Capacity

 

The number of database connections that will be created when the pool is started. Note that if the server is unable to create this number of connections, creation of the connection pool will fail.

     

Maximum Capacity

 

An upper limit on the number of connections.

     

Capacity Increment

 

The number of new connections that will be created when all the existing connections are occupied.

     

Login Delay Seconds

 

Some databases freak out if bombarded by simultaneous requests for connections. Use this property to build in a (brief) delay between new connection requests .

     

Refresh Period

 

WebLogic tests the database connections every so often to make sure that they are still in working order. This value sets the number of minutes between tests.

     

Supports Local Transaction

 

Set to true if the XA connection pool supports SQL with no global transaction.

     

Allow Shrinking

 

Whether or not the number of connections in the pool is permitted to shrink.

     

Shrink Period

 

If shrinking is allowed, this is the number of minutes that must elapse between a connection going idle and the connection pool being shrunk. Note also that this comes into play only when the pool has been enlarged beyond its initial capacity.

   

Testing

     

Test Table Name

 

For databases such as Oracle that do connection testing, enter the test table name here. (DUAL is the test table name for Oracle.)

     

Test Reserved Connections

 

By checking this box, you are telling WebLogic to test a connection requested by a client. So doing incurs a slight performance hit but guarantees the client a working connection.

     

Test Released Connections

 

By checking this box you are telling WebLogic to check whether connections that have just been released by a client process are still functional.

 

Multipools

   

In WebLogic 6.x, Multipools are a mechanism for creating pools of pools.

   

General

Pool Name

 

The JDBC connection pool to which the data source will be linked. The pool specified here should already have been created.

     

Row Prefetch Enabled

 

When checked, this option improves performance by precaching the number of rows specified by Row Prefetch SIze. It is not necessary to prefetch rows if all processes are running on the same machine.

     

Row Prefetch Size

 

When Row Prefetch is enabled, this is the number of rows that will be sent to client processes upon request.

     

Stream Chunk Size

JNDI Name

 

JNDI name of the data source.

     

Pool Name

 

Name of the JDBC pool with which this Tx data source is to be associated.

     

Enable Two-Phase Commit

 

Two-phase commitment increases recoverability in the case of a disaster at a slight cost to performance.

     

Row Prefetch Enabled

 

When checked, this option will download rows to (presumably remote) client processes in batches of the size specified by Row Prefetch Size. Not necessary if client processes are running under the local JVM.

     

Row Prefetch Size

 

The number of rows to be prefetched.

     

Stream Chunk Size
