RE: Need to Log on 2000 users
Hi gaurav and fellow DBAs, I ran into the same problem once on a Sun Solaris 5.9 box. The lines on your sqlnet.ora file have a great deal of impact on how authentication works. remote_os_authent=true will allow people remote users to connect to your instance using the credentials on the machine they are logged in. This means that OS credentials used are niether Oracle's nor the local OS's that your insance resides on. I don't know about you but I 'goose bumps' at the thought of allowing users to user THEIR OS authentication credentials. If you are comfortable with they way your authentication works, omit the following lines: If I were you, I would take the SQLNET.AUTHENTICATION_SERVICES = (none) out of my sqlnet.ora file and change your remote_os_authent = false on my ora init instance file. An excelent way to troubleshoot the sqlnet.ora file is to create a copy of it as a backup and try taking out a line at a time. Restart your ora instance every time you delete one of your lines in the file and test your login. Another pointer I think you are missing grant connect and grant resource on your grant statement.

Re: Need to Log on 2000 users
Jeremiah, Where do you get 128Gb? For 2000 users that is ~65M per user, which seems like an excessive estimate. While I probably wouldn't want to run 2k users on a single Windows server, I think you could do it for test purposes. Use orastack to reduce the memory per thread to 500k, set small sort_area_size, etc. Don't see why not. Jared On Friday 30 May 2003 02:14, Jeremiah Wilton wrote: You mean 2000 concurrent sessions?

Re: Need to Log on 2000 users
As well as using orastack, go a few steps further and tune the SGA to buggery (make it lean but keen) and set as high a pga_aggregate_target as possible and you might make it (depending on what the 2000 users are doing and depending on how many of them are doing what they're doing concurrently). As previously suggested, shared servers could be a goer but if dedicated is a must, consider the above.

RE: Need to Log on 2000 users
Sorry Munish, I misinterpreted your question. But Jared's suggestion is a good one. You can use orastack to set parameters to maximize memory use for your test database. And too, 128Gb sounds like a pretty large number for 2000 users!
