Compatibility across releases for ClearCase clients and servers

Preventive Service Planning


Abstract

IBM® Rational ClearCase operations require communication between multiple client and server components. If some components run different ClearCase® versions, operations can be interrupted or stopped by software compatibility issues. To prevent problems, use the compatibility information in this technote to make sure that all components in your environment can operate together successfully.

Content

All versions of the ClearCase® software running on the clients and servers in your environment must be compatible.

Compatibility considerations

When you consider compatibility issues, keep these points in mind:

  • Compatibility is guaranteed if all components run the same ClearCase® version.
  • Before you upgrade clients and servers, review the ClearCase compatibility information to ensure that the ClearCase® version you are upgrading to is compatible with the versions running on other clients and servers in your environment.
  • If you are using ClearCase® in a UCM environment, review the known issues:
  • All compatibility issues in a UCM environment can be avoided by upgrading the server to a version that is at the same level or later than the version running on the client.

Note: This technote provides the most up-to-date information about compatibility across releases, superseding the compatibility information included in IBM® Documentation for ClearCase® version 7.1.2 and earlier.

Additional information

  • For more information about Rational product compatibility, use the Software Product Compatibility Reports website from IBM® Support to run reports about operating systems, prerequisites, server virtualization environments, and other product compatibility information.
  • For more information about version terminology, see technote 318829.

ClearCase Compatibility Information

The following tables show the compatibility paths when ClearCase® components are not running the same versions of Rational® ClearCase®. In these tables, Client refers to Rational® ClearCase® client software that includes one or more of these components:

  • ClearCase® native client.
  • ClearCase® client by using ClearTeam Explorer for dynamic or snapshot views only.
  • CM/CCRC WAN server, which by default also serves as a view server for web and automatic views.

These tables provide a list of compatibility combinations.

Table 5A. VOB database compatibility for Linux releases

Note: All platforms except for Linux and Windows are compatible across all releases. For Linux, a number of incompatibilities exist in version 9.0.1.x between the 32-bit linux_x86 and the 64-bit linux_x86_64 and linux_ppc64le offerings. The following table describes the general compatibility. If the versions are not compatible, a VOB reformat is required. For more information about VOB database compatibility, see technote 562843.
