First of all: which DBMS are you using? - as embedded ones (like sqlite) are not designed for multiclient usage

I am using Oracle.

Oracle is build for multi-user, so probably there is a problem with your code...
You should share with us the exact problem (error if any) and the code around which the problem happening...

What is the problem you're facing? Are you getting errors? Are users not able to log in or what?

If you are trying to update a database from two sources (even if it is not simultaneous) you need to look at using a server based database system - which means SQL server or MySql. If you are using one of those, then it should not be a problem, unless you are doing something rather odd.

If you are using a SQL type database such as SQLCE, SQLite, or Access directly, then trying to do anything with more than one user is a very bad idea: it will cause loads of problems.

So your problem is either likely to be that you are using a single user database - in which case change to a server based system - or that the problem is unrelated to multiple users but in your code directly instead, and it only shows up in production. The most obvious of these is concatenating strings to form an SQL statement, which leave you open to SQL Injection, as well as giving problems with "real world" data that don't show up in development.

Whatever, we would need the error messages and related info to have any chance of helping you further.
