Additional Configuration

You can use Substation ES to specify different interface configurations to meet various business requirements.

For example, you can configure a single Substation ES instance to simultaneously communicate with multiple CICS regions. Alternatively, you can configure multiple Substation ES instances to communicate with the same CICS region. The configuration choice depends on your system requirements.

• Adding an Additional Substation ES CICS Interface
  You can add an additional Substation ES CICS Interface connection to a CICS region.
• Adding an Additional ESB Interface
  You can add an additional TIBCO ESB Interface (formerly referred to as the Transformer) connection to a CICS region.
• Adding a Rendezvous ESB Interface with SSL
  Adding SSL for a Rendezvous interface is done in the Rendezvous daemon definition, not in Substation ES.
• Adding Substation ES Instances to a Single CICS Region
  You can configure multiple Substation ES instances that communicate to a single CICS region.
• Using Connection Factories
  Substation ES uses the TIBCO Enterprise Message Service connection factory for all EMS connections. Substation ES creates a default Connection Factory Object when the ESB interface starts, and then populates the Connection and Re-Connection Parameters using the definition from the Substation ES Configuration File.
• Using RVDQ with Multiple Substation ES Instances
  This section describes the process taken to configure multiple Substation ES instances to use RV distributed queue processing to communicate with a single CICS region.
• Using RVDQ with One Substation ES Instance
  This section describes the process taken to configure one Substation ES instance to use RV distributed queue processing to communicate with a single CICS region or multiple CICS regions.
• Using Opaque Fields and Message Sizes
  When using RV ESB, you can configure and use Opaque field and message size settings. With the settings, Substation ES can calculate the size of data communication with the BES (CICS or IMS).
