Issue/Introduction

Using a JDBC Type 4 connection from Linux does not connect to the mainframe Datacom Server.

The connection attempt hangs until it times out. There are no error messages on the mainframe.

 

 

Environment

Release : 15.0

Component :DATACOM SERVER

Cause

The JDBC Type 4 connection string is using the ApplicationID= parameter, it must instead use the ServerName= parameter.

Resolution

The connections string for a JDBC Type 4 connection has the following format:

jdbc:datacom://<hostname>:<hostport>/ServerName=,UserID=,Password=

ServerName must match the SERVERNAME= parameter in the mainframe Datacom Server startup.

hostport must match the TCPIP_PORT= parameter in the mainframe Datacom Server startup.
