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.

Table 1. Information about this migration action
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:
  1. 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.
  2. 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.
