Online Traces

In an online environment, the CA Ideal traces work as follows:

Both traces are available online. However, online, the separate DIAL‑only trace output file is not supported. All information goes to the VPE trace file. The VPE trace must always be activated first.
Online, there is only one VPE trace file for all CA Ideal users. A trace can be local to a single user or globally include all users, but all traces using a given CICS region share the same file. As in batch, information can be extracted from the VPE trace file selectively (for example, by the function or by the time an error occurred).
Under z/OS you can print or display extracted information online using the CA Ideal output processor. Under VSE, the trace can be activated online, but trace information can be extracted only in batch.

To minimize the degradation of the online system by traces, run them in batch whenever possible.
