As John K. mentioned, using 'sar -v' at the time of opening the production database would tell you more about the number of file opened at that time. Both your NFILE and MAX_FILES number look too small. What's set for MAXUSERS? HTH. - K i r t i ;) -----Original Message----- Sent: Tuesday, June 04, 2002 11:48 PM To: ORACLE-L@fatcity.com; oracledba@lazydba.com; kirti.deshpande@gtedc.gte.com Kirthi NOTE Point 3) (Bottom) We were able to OPEN a Small Dummy Database on the Failing Production Server . If the system wide limit for the number of simultaneously open files is exceeded Would the Dummy Database OOEN Either ? NOTE nfile = 200 max_files = 200 Approx 75 User processes All inclusive would exist on the machine Thanks for responding -----Original Message----- Sent: Wednesday, June 05, 2002 5:58 AM To: Multiple recipients of list ORACLE-L Vivek, You are right, this is an OS related issue, but a DBA must be aware of why it happens ;) Error 23 means 'File Table Overflow' and it is generated when the system wide limit for the number of simultaneously open files is exceeded. It is controlled by a kernel parameter 'nfile'. which defaults to a value arrived at by a formula that uses 'maxusers' (and a couple of other) kernel parameters. You can check the values set for 'maxusers' and 'nfile' on these servers, and get your SA to increase those on the server where you had a problem starting the database. Use '/usr/sbin/kmtune -q ' command to check currently set value for 'nfile' and 'maxusers'. Read more about 'nfile' at http://docs.hp.com/hpux/onlinedocs/os/KCparam.Nfile.html.

NOTE Though ORA-1092 was often succeeded by the message :- "Error Num 23" NO Idea what Error Num 23 Stands for ? Thus This seems to be Some OS /Hardware Issue with the Previous Production Database on which the Database would NOT Open after OS RE_Installation . For Problem Details Go Below .

Thanks again Vivek -----Original Message----- Sent: Monday, June 03, 2002 4:51 PM To: LazyDBA.com Discussion Vivek: I guess SMON runs the command to get the details for regular cleanup. You can use few undocumented events to get the things done depending on the seriousness of the database. These events just asks the SMON to skip few things during recovery and pretty harmless.
