Authoritative Documents

Reference Materials

While IBM Streams documentation remains available for historical context, always defer to the current Teracloud Streams documentation for accurate, up-to-date information. Future updates will clarify the availability of additional reference materials.

System Requirements and Required Upgrades

Operating System Support

  • Applications intended for deployment on RHEL 8 must be compiled on RHEL 7 first.
  • The included dependency checker identifies required RHEL 7 compatibility RPMs when deploying on RHEL 8.
  • RHEL 7 support is retained for backward compatibility during transition periods.

Apache Zookeeper Upgrade

Users must upgrade Apache Zookeeper to version 3.8.x (tested with 3.8.4) to maintain compatibility and meet enhanced security standards. Detailed upgrade procedures are outlined in Chapter 8 of the Installation and Configuration Guide.

New Features and Important Changes

Modernized Technology Stack

  • Apache Zookeeper: 3.8.4
  • Oracle Java: 8.0.8-25
