Anne, Manual SA22-7625 "Setting up a Sysplex" is *the* manual to answer all your questions with regard to Sysplex issues.
Chapter 9.5 Deleting log data and log data sets, states: In general, applications should handle deletion of log data from a log stream. If the application does not manage deletion, the installation might be able to use the retention period and automatic deletion functions in system logger to manage the amount of log data you keep in each log stream So you should first check what logstread management your application does. If you delete data from the logstream, that the application needs later, you will create problems. Chapter 9.4.6 Managing log data: How much? For how long? Explains more about deleting logstream data. Kees. "Gray, Larry - Larry A" <[EMAIL PROTECTED]> wrote in message news:<[EMAIL PROTECTED] m>... > Deletion of an offload dataset only occurs when a new offload dataset for that logstream gets allocated.
