Hi, AIXTHREAD_SCOPE=S is the only parameter that is recommended by Oracle in AIX, but this is a simple unix environment vaiable (set in Oracle user's .profile). http://metalink.oracle.com/metalink/plsql/ml2_documents.showDocument?p_database_id=NOT&p_id=169706.1 Oracle recommends this is due to some performance reasons as i learnt while googling. Also If you didnt validate your environment w/ oracle provided script, please use the below link: http://metalink.oracle.com/metalink/plsql/ml2_documents.showDocument?p_database_id=NOT&p_id=283743.1 Regards, Madhu -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx To: oracle-l@xxxxxxxxxxxxx Sent: 7/7/2005 10:31 AM Subject: Oracle 9.2.x - AIX 5.x - Kernel Parameters Oracle 9.2.x - AIX 5.x - Kernel Parameters Anybody have any personal notes, references, docs, links, for the best proper Oracle 92x - AIX 5.x Kernel Parameters settings I got this from METALINK; set AIXTHREAD_SCOPE=S in the environment: export AIXTHREAD_SCOPE=S and I have the standard SEMMSL, SEMMNS, SEMOPM, SEMMNI, SHMMAX, but nothing else.
