Updating Java on IBM i

Before installing IBM Traveler, ensure that the IBM i server is running Java 8.

About this task

Starting with version 9.0.1.19, IBM Traveler requires JVM 8 32-bit as the default JVM for all supported versions of IBM i, to align with default JVM version changes for Domino 9.0.1 FP9.

Note: To use the 64-bit JVM, set JavaUse64BitJVM=1 in the NOTES.INI of the Traveler server.

For more information on using Java with IBM i, see the following articles:

Table 1 lists the default JVM versions for Traveler 9.0.1.19 with Domino 9.x on the supported versions of IBM i.

Table 1. Default JVMs for Traveler on IBM i
IBM i version	Traveler 9.0.1.19 for Domino 9.0	Traveler 9.0.1.19 for Domino 9.0.1
IBM i 6.1	Not supported	Not supported
IBM i 7.1	JVM 8 32-bit	JVM 8 32-bit
IBM i 7.2	Not supported	JVM 8 32-bit
IBM i 7.3	Not supported	JVM 8 32-bit

Note:

JVM 8 is not supported on IBM i 6.1.
Domino 9.0 does not support IBM i 7.2 and 7.3.
Domino 9.0.1 does not support IBM i 6.1.

Table 2 lists the required IBM i software for running Traveler on Domino.

Table 2. Required IBM i software
IBM i Software	i 7.1	i 7.2	i 7.3
IBM Developer Kit for Java J9	5761JV1 Option *BASE 5761JV1 Option 16 5761JV1 Option 17	5770JV1 Option *BASE 5770JV1 Option 16 5770JV1 Option 17	5770JV1 Option *BASE 5770JV1 Option 16 5770JV1 Option 17

Note:

For IBM i 7.1 (5761JV1) and 7.2 (5770JV1), Options 16 and 17 are additionally required.
5770JV1 Options 16 and 17 are available with IBM i 7.3 media.

For example, when starting Traveler, the following error messages will be displayed in the Domino console if the required Java Option is not installed on IBM i.
