Under CICS, the Server Option accounting functions store information in a VSAM ESDS accounting log file. As installed, this file is named SYTACCT1. The Server Option appends accounting records to that file until it becomes full; all subsequent attempts to write accounting records to that file are rejected. To make room in the file, do one of the following:
Archive or delete accounting records
Change the name of the accounting log
Change the underlying VSAM file assigned to this name
