Symptom

You execute an upgrade or an installation for a Java stack. Various SAP commands (for example, STARTSAP, STOPSAP) require the host name of your IBM i as a parameter.

Reason and Prerequisites

This problem usually occurs during upgrades or installations if there is a hyphen in the name of the host you are using. This problem is not displayed if you call the SAP command in the i5/OS command line.

Solution

Although the hyphen is a valid character in the host name, an object name in i5/OS is not allowed to contain this hyphen without anything else. Parameters that contain the host name must place such names in single quotation marks.
For installations and upgrades, as well as certain maintenance activities, SAP commands are called from a separate environment (for example, Java). Therefore, they are not prepared using the i5/OS command line, but are sent directly to the operating system. In such cases, the hyphens must be transferred by the application.
The following applications have been revised for this in all releases:
- SAP Upgrade Java (SAPJup)
- SAP Enhancement Package Installer (SAPehpi)
- Java Support Package Manager (JSPM)
As far as possible, you should always use the most recent patch level for these applications. All of the relevant, corrected applications refer to this note (Note 1362434). You should therefore pay attention to the relevant change history. The corrected versions will be rolled out as of August 2009.
