An IXGWRITE request will be rejected with a return code of X'08' and a reason code of X'0868 ' while the log stream's staging datasets are being formatted. The first application to connect to a log stream on a particular system causes logger to format the log stream's staging data sets on that system. Each system has its own set of staging datasets. Applications should not resume issuing write requests until the temporary condition has been resolved. Applications that do not want to use ENF event code 48 or that are unauthorized and cannot use ENFREQ will still receive system logger service return and reason codes indicating failure or resource shortages. These applications can simply set a timer and retry the requests to see if the problem has resolved itself.
