Setting up the error log

Why and when to perform this task

WebSphere Application Server for z/OS uses an error log to record error information when an unexpected condition or failure is detected within the product's own code. Such unexpected conditions or failures include:

Because WebSphere Application Server for z/OS is predefined as a z/OS system logger application, you can use a log stream as the product's error log. Doing so offers the following flexibility:

When your installation first customizes and verifies WebSphere Application Server for z/OS installation, you have the option of defining the error log as a log stream. Using the ISPF customization dialog to configure a base application server node, you can specify log stream characteristics, including sizes. After verifying installation, you can change the log stream used for normal operations.

For additional information about z/OS log stream requirements, access the z/OS MVS Setting up a Sysplex, SA22-7625 available on the z/OS Library Web page
