Custom JDBC Data Source based on Sybase

Hi experts!

My goal is to configure new custom jdbc 2.0 (with XA support) data source based on already integrated (PI uses the same driver) Sybase driver.

My configuration:

PI version: 7.40

Settings:

Driver Name - SYSTEM_DRIVER (same as PI uses, Sybase)

Sql engine - Vendor SQL

JDBC version: 2.0 (with XA support)

Object factory: none

XADS Class Name: com.sybase.jdbc4.jdbc.SybXADataSource

Additional properties:

PortNumber: 4901

Password: sapsa password

ServerName: localhost

DatabaseName: dbname
User: sapsa

I have searched a lot of manuals, everything seems nice. But every time i try to connect, i get an error:

Caused by: com.sap.engine.frame.core.database.DatabaseException: Exception of

type java.sql.SQLException occurred: JZ006: Caught IOException:

java.net.ConnectException: Connection refused.

com.sap.engine.core.database.impl.DataSourceAdministratorImpl.createDataSource(DataSourceAdministratorImpl.java:49)

com.sap.engine.services.dbpool.deploy.ContainerImpl.startDataSources(ContainerImpl.java:1644)

Has anyone ever have an error like this one?

Thanks in advance!
