Plan for the removal of IBM HTTP Server powered by Domino
Description
z/OS V2R1 was the last release to include the IBM HTTP Server powered by Domino. New base element, IBM HTTP Server - Powered by Apache (IHSA), is introduced in z/OS V2R2. This element replaces IBM HTTP Server powered by Domino. z/OS V2R2 contains IHSA at level 9.0.
If your installation is using IBM HTTP Server powered by Domino, you must migrate to IBM HTTP Server - Powered by Apache. It is strongly recommended that you perform this migration in two phases, as described in Steps to take. Both IBM HTTP Server - Powered by Apache 8.5.5 and IBM HTTP Server - Powered by Apache 9.0 are supported on z/OS V2R2. Note, however, that IBM HTTP Server - Powered by Apache 8.5.5 support on z/OS V2R2 is planned to continue only until the end of service date for z/OS V2R1 (planned for September 2018).
IBM HTTP Server powered by Domino is not supported on z/OS V2R2.
Table 1 provides more details about this migration action. Use this information to plan your changes to the system.
Element or feature: | IBM HTTP Server powered by Domino. |
---|---|
When change was introduced: | z/OS V2R2. This change was also announced in the statement of direction IBM United States Software Announcement 213-292 "IBM z/OS Version 2 Release 1 delivers the foundation for Smarter Computing," dated July 23, 2013. |
Applies to migration from: | z/OS V2R1 and z/OS V1R13. |
Timing: | Before installing z/OS V2R2. |
Is the migration action required? | Yes, if you currently use IBM HTTP Server powered by Domino. |
Target system hardware requirements: | None. |
Target system software requirements: | None. |
Other system (coexistence or fallback) requirements: | None. |
Restrictions: | None. |
System impacts: | The HTTP servers that are included in other IBM licensed programs, such as WebSphere Application Server, are not affected. This migration action applies only to users of the IBM HTTP Server that is included in the base z/OS operating system. |
Related IBM Health Checker for z/OS check: | The check IBMZMIG,ZOSMIG_HTTP_SERVER_DOMINO
is used to determine whether IBM HTTP Server powered by Domino is
in use on your system. The check is written in REXX and is provided
on an as-is basis at http://www.ibm.com/systems/z/os/zos/installation/HTTP_Health_Checker.html. The check is not provided in an APAR; for instructions on adding it to your system, see the web page. |
Steps to take
- Before you install z/OS V2R2, use the separate licensed program
z/OS Ported Tools HTTP Server feature (5655-M23) on z/OS V2R1 or z/OS
V1R13. You can run the IBM Ported Tools HTTP Server and the IBM HTTP
Server powered by Domino concurrently, if necessary, for certain functions
that do not support the IBM Ported Tools HTTP Server on z/OS V2R1
or z/OS V1R13, such as Infoprint Server at those release levels (see
"Infoprint migration action for HTTP Server").
In this phase of the migration, you can perform much of the migration work for z/OS V2R2 IBM HTTP Server in advance and stabilize on IBM HTTP Server - Powered by Apache. The z/OS Ported Tools HTTP Server feature is at level 8.5.5 (Apache V2.2.8 level).
- After you install z/OS V2R2, migrate from z/OS Ported Tools HTTP Server feature to z/OS V2R2 IBM HTTP Server - Powered by Apache. In z/OS V2R2, IBM HTTP Server - Powered by Apache is at the 9.0 level (based on Apache V2.4). Here, you need only to perform the migration actions between IBM HTTP Server 8.5.5 and 9.0, which are fewer than the number of migration actions that are needed to move from IBM HTTP Server powered by Domino directly to IBM HTTP Server - Powered by Apache at the 9.0 level.
