Data Gate system requirements

The following hardware and software requirements must be met to run the IBM Data Gate for z/OS service on IBM Cloud Pak for Data.

Version support

The current service version is IBM Data Gate for z/OS Version 5.0.0.

The current service version is compatible with:

  • IBM Cloud Pak for Data Version 4.8.0 (5737-H76)
  • IBM Cloud Pak for Data Db2 (5737-L73)

Hardware requirements

Supported architectures
  • x86 64-bit
  • IBM Z (s390x)
Min. number of virtual CPUs required for installation
2
Min. amount of memory (in GB of RAM) required for the service to run
13
Min. amount of storage (in GB) required by the service
50
Supported storage types
For a list of the supported storage types and the recommended storage classes, see the entries for Data Gate in the following sections:
Note:
  • For optimal performance, at least a 10-Gigabit Ethernet connection is recommended between the IBM Z System and the IBM Cloud Pak for Data system.

Software dependencies

Supported IBM Cloud Pak for Data platforms
See Cloud development environments.
External dependencies
  • IBM® z/OS Version 2.4 (5650-ZOS) or higher.

    For the z/OS Communications Server component of z/OS, install the following program temporary fixes (PTFs):

    Tip: To avoid a performance degradation during load operations, also install the PTF for APAR OA61558.
  • One of the following database management systems:
    • IBM Db2 13 for z/OS (5698-Db2 or 5698-DBV)
    • IBM Db2 12 for z/OS (5650-DB2® or 5770-AF3).
    • Remote Db2 database.

    For the required Function Level and the list of required PTFs, see Installing Db2 maintenance to enable Data Gate.

  • Distributed data facility (DDF) with a secure port, which is configured for network encryption through AT-TLS. See Configuring network access between Data Gate and IBM Z for configuration information.
  • Data Gate requires a valid Db2 Connect Unlimited edition license so that Data Gate can connect to Db2 for z/OS via JDBC. Data Gate users need to take the steps in Activating the Db2 Connect Unlimited license on a Db2 for z/OS subsystem to perform the server-side Db2 Connect Unlimited edition license activation on Db2 for z/OS source subsystems.
Service dependencies
Unless you use an (optionally supported) remote Db2 target database, you need one of the following Cloud Pak for Data target database services:
  • IBM Db2 Warehouse 11.5.8.0 or higher
  • IBM Db2 11.5.8.0 or higher
Note: See the Db2 installation requirements and recommendations in Installing a Db2 instance for Data Gate on Cloud Pak for Data.

Multitenancy support

  • Multiple instances of the Data Gate service can be installed within a single IBM Cloud Pak for Data deployment.
  • Multiple instances of the Data Gate service can be installed on the same cluster (on separate IBM Cloud Pak for Data deployments).
