process locking

[8592x2]

Question concerning process traffic control:

I am enhancing a multi-user database to increase the speed of our
database transactions. We developed the database ourselves and hope
to improve the marketablity of the product. However we have run into
several complications in porting the software to UNIX.

Currently I am investigating the utilities available within UNIX to
provide process locking for the multi-user system. In past revisions
we used a database server process that enabled the database administrator
to prioritize database access. This provided functional database service,
but transaction processing was required to be synchronous. We are hoping
that we can improve our database speed by using database access locks to
provide asynchronous transaction processing. The problem is we have yet
to find an elegant process lock within UNIX. What possible solutions
exist for this problem?
