DB status
• Manpower– 1 DBA ( 25%): [email protected]– 1 DBA (100%): [email protected] (just started)– [email protected] (deputy)
• Streams– tests with ATLAS and LHCb done
• Problems– memory settings – solved by reducing streams_pool_sizeORA-04031: unable to allocate 16 bytes of shared memory ("shared
pool","select obj#,type#,ctime,mtim...","sql area","kglhin: temp")– ORA-Messages unresolvedORA-10388: parallel query server interrupt (failure)WARNING: inbound connection timed out (ORA-3136)
• To do– scheduled backup– OEM agent installation for own Grid Control– check parameter settings (sga_target ?)
