ERRORLOGBUFF_S2 specifies the number of S2 space error log buffers reserved for system error log entries. Each buffer is ERLBUFFERPAG_S2 in length. If ERRORLOGBUFF_S2 is too low, messages might not be written to the error log file. If it is too high, the buffers can consume unnecessary physical pages. If you increase ERRORLOGBUFF_S2, you must either run AUTOGEN or manually increase the size of both the system dump file and the error log dump file. ERRORLOGBUFF_S2 is an AUTOGEN parameter on Alpha and Integrity servers.
