PowerExchange Message Log File

PowerExchange Message Log File

By default, PowerExchange writes most messages to the PowerExchange message log file.
PowerExchange creates this file if it does not exist.
The following table shows the default name and location of the PowerExchange message log file by operating system:
Operating System Type
Message Log File Name
A member of the LOG file in the PowerExchange data library,
, which PowerExchange creates during installation.
Linux, UNIX, and Windows
A file in the current working directory of the PowerExchange process that is running.
DTLLOG DD data set
A data set that is allocated by the DTLLOG DD statement in the JCL for a PowerExchange component that issues messages. This DD statement can point to a permanent data set or to a SYSOUT data set.
When messages are written to a single file, without manual intervention, the volume of data continues to grow until the PowerExchange message log file becomes full. This out-of-space condition usually occurs for long-running PowerExchange tasks, such as the PowerExchange Listener. Also, PowerExchange must open and close the PowerExchange message log file to write each message. This open and close activity can decrease performance and increase resource utilization when message volume is high.
