Enterprise information systems (EIS)

If an application accesses enterprise information systems (EIS) using resource adapters, then consider how to maintain access to the EIS from the cloud or consider migrating the EIS to the cloud.

The following items indicate that an EIS is accessed:

• References to the javax.resource.cci.Connection and javax.resource.cci.ConnectionFactory Java classes
• The <res-type>javax.resource.cci.ConnectionFactory</res-type> deployment descriptor element in the application.xml, application-client.xml, ejb-jar.xml, or web.xml file
• The presence of a META-INF/ra.xml file

This rule is flagged once per Eclipse project or Java archive.

How to Resolve

If your application is able to directly access your EIS, no further action is required.

Otherwise, one option is to move the EIS application to the cloud as part of the migration. Alternatively, you can use a VPN tunnel, such as the IBM Secure Gateway for IBM Cloud, to create a secure connection for your existing on-premises EIS. For more information about configuring a secure connection, see Configuring a VPN. After you configure your gateway, connect your application to the new destination by using the cloud host and port number that is provided when you created the destination. The following URLs are examples of Customer Information Control System (CICS) URLs:

• tcp://<cloud host>:<cloud port>
• ssl://<cloud host>:<cloud port>
