Usage

The DRDA correlation token is used for correlating the processing between the application server and the application requester. It is an identifier dumped into logs when errors arise, that you can use to identify the conversation that is in error. In some cases, it will be the LUWID of the conversation.

If communications are not using DRDA, this element returns the appl_id (see appl_id).

If you are using the database system monitor APIs, note that the API constant SQLM_APPLID_SZ is used to define the length of this element.
