This file describes how to set up CTRACE
WebSphere Application Server for z/OS uses z/OS component trace (CTRACE) facilities to manage the collection and storage of trace data. Unless you configure specific CTRACE controls, WebSphere Application Server for z/OS records its trace data in address-space buffers in private (pageable) storage. This data is not accessible unless a dump of the address space is taken.
Although CTRACE data is primarily output for IBM service personnel to use, exploiting CTRACE capabilities at your installation allows you to have additional trace data available when a problem first occurs. Because CTRACE efficiently uses system resources, you can collect valuable trace data with minimal impact on performance.
When your installation first customizes and verifies WebSphere Application Server for z/OS installation, you have the option of defining CTRACE controls and resources. Using the ISPF customization dialog to configure a base application server node, you can specify:
The ISPF customization dialog generates instructions for:
