Before You Install the Product

Installation is easier and more effective if you complete your planning before you begin.

Before you begin your installation:

Read the IBM® Sterling Connect:Direct® for z/OS® Release Notes for the latest product information.
Verify hardware and software requirements. Review Installation Requirements for hardware and software requirements.
Determine whether your system uses a Multi-Image Manager (MIM) or Global Resource Serialization (GRS) system. For more information, see Sterling Connect:Direct Enqueue Resource Management.

Configuring Sterling Connect:Direct for z/OS
VTAM Definitions

Optional Configuration Tasks
Sterling Connect:Direct Enqueue Resource Management
This topic includes definitions of Sterling Connect:Direct resources for a Multi-Image Manager (MIM) or Global Resource Serialization (GRS) system.
Initialization Errors
This topic describes the causes of common errors, such as inadequate storage or errors in the statistics log, that may occur when you initialize Sterling Connect:Direct for z/OS.
Installation Requirements
Sterling Connect:Direct for z/OS requires the following hardware and software. However, this is not a complete list. See the Program Directory for the complete list of requirements, and for more information on several of the items listed below:
Virtual Storage Requirements
Preparing TCP/IP Configuration (Optional)
Security Planning
Planning for Parallel Sessions and Process Recovery
Planning the Network Map
The network map identifies the local Sterling Connect:Direct node and the nodes where it can communicate. It consists of a local node entry and one or more adjacent node entries.
Planning for Disaster Recovery Testing
When you back up a Sterling Connect:Direct system for business continuity testing (also known as "disaster recovery testing or DR testing"), you create a snapshot of the DTF files at one point in time. If the DTF is running when the backup is taken, the captured files may not be in a synchronized known state.
Planning for Sterling Connect:Direct File Agent
Sterling Connect:Direct File Agent must be installed in a directory of the z/OS UNIX System Services component and configured to communicate with the Sterling Connect:Direct server. Use a PC for terminal emulation when you are ready to create a configuration file using Sterling Connect:Direct File Agent. Sterling Connect:Direct File Agent uses mount points, which are HFS/zFS files requiring at least 20 cyclinders of available space. See IBM Sterling Connect:Direct for z/OS Release Notes for software requirements for Sterling Connect:Direct File Agent.
