Hi, It's a fact that you have these errors because AIX doesn´t handle such big files; I don´t remember exactly the maximum size for the datafiles; but is a limitation of the operating system. I had an oracle database 8.1.7 with AIX 4.3.3; there´s an attribute that enables the operating system to handle big files; you have to initialize this attribute when you define the oracle administrator's user , and I´m sure you won´t have problems. regards, Martha -----Mensaje original----- De: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx]En nombre de Seema Singh Enviado el: Lunes, 14 de Junio de 2004 12:03 p.m. Para: oracle-l@xxxxxxxxxxxxx Asunto: AIX(VERSION 4) /Oracle8172 Hi, I have one instance on AIX version 4 .This instance is crashing on regular basis.I have been noticing following problem. ORA-16038: log 3 sequence# 723 cannot be archived ORA-19502: write error on file "", blockno (blocksize=) ORA-00312: online log 3 thread 1: '/u02/oradata/DSS/redo3a.log' ORA-00312: online log 3 thread 1: '/u04/oradata/DSS/redo3b.log' ARCH: Connecting to console port... ARCH: or ORA-00476: RECO process terminated with error PMON: terminating instance due to error 476 Instance terminated by PMON, pid = 133128 or ARC1: Error 19504 creating archivelog file '/u06/oracle/b These all errors are coming since we created maxsize 2048m of datafiles in autoextend mode. AIX version is 4.I'm assuming AIX 4 doesn't handle 2GB files.Metalink say it's due to file size.Doesn any one have such situation in past? If yes how did fixed pl? ANy suggestions are welcome. thx -seema _________________________________________________________________ MSN Toolbar provides one-click access to Hotmail from any Web page ?
