Upgrade Java support for IPP Server and Infoprint Central
Description
In z/OS V2R2, the Internet Printing Protocol (IPP) Server used in Infoprint Server and Infoprint Central require Java V7.1. If the JAVA_HOME environment variable specifies the location of an earlier version of Java, you must update the JAVA_HOME environment variable.
Table 1 provides more details about this migration action. Use this information to plan your changes to the system.
Element or feature: | z/OS Infoprint Server. |
---|---|
When change was introduced: | z/OS V2R2. |
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 use IPP Server or Infoprint Central and specify the JAVA_HOME environment variable. You are using IPP Server if start-daemons={ippd} is specified in the Infoprint Server configuration file. You are using Infoprint Central if the start-daemons={ssid} attribute is specified in the Infoprint Server configuration file. The configuration file's default location is /etc/Printsrv/aopd.conf. However, you might have specified a different location in environment variable AOPCONF. |
Target system hardware requirements: | None. |
Target system software requirements: | IBM® 31-bit SDK for z/OS®, Java™ Technology Edition, V7.1 (5655-W43); Infoprint Central can also use IBM 64-bit SDK for z/OS, Java Technology Edition, V7.1 (5655-W44). |
Other system (coexistence or fallback) requirements: | None. |
Restrictions: | None. |
System impacts: | z/OS V2R1 and V1R13 Infoprint Server will not operate with IBM HTTP Server - Powered by Apache. After you install z/OS V2R2, you must change the configuration of the z/OS V2R2 Infoprint Server to operate with IBM HTTP Server - Powered by Apache, which is included in z/OS V2R2 as a base element. |
Related IBM Health Checker for z/OS check: | None. |
Steps to take
Follow these steps:
- Install IBM 31-bit SDK for z/OS, Java Technology Edition, V7.1 (5655-W43) or IBM 64-bit SDK for z/OS, Java Technology Edition, V7.1 (5655-W44). IPP Server requires the 31-bit version of Java V7.1.
- If you use the IPP Server, edit the aopstart EXEC to update the directory path specified in the JAVA_HOME environment variable to /usr/lpp/java/J7.1 or wherever you specified the location.
Note: If you installed Java V7.1 in the default Java directories,
you do not need to specify the JAVA_HOME environment variable. If
JAVA_HOME is not specified, IPP Server or Infoprint Central looks
for Java files in the /usr/lpp/java/J7.1 directory.
