Raw-level Locking

[raywang]

I used sp_indexoption to allow row locks and disallow page locks on all indexes of a heavily contented table (lots of concurrent selects/inserts/updates). The first error I saw was "The SQL Server cannot obtain a LOCK resource at this time. Rerun your statement when there are fewer active users or ask the system administrator to check the SQL Server lock and memory configuration.". I restarted the sql server and everything is ok (the server is not very powerful and will be beefed up).

My question is that with the above settings, will the select statements acquire row-level shared locks as well? Since our select queries are fairly complicated, my main concern is that we may frequently run of of resource even with a more powerful machine. Is my concern valid or I got everything wrong?

Thanks a lot.

Use perfmon to check locks used and memory usage on the server.
