We have developed business application software using Oracle 10g as the back end and VB as the front end.
When Oracle 10g is installed on Windows 2003 server, it has by default 300 Open Cursors and 150 Processes. There are approx 50-100 simultaneous users working on our software at the Client end.
Software works fully OK for days and months togather. Rarely we get that limit of Processess is exhausted and then it does not allow users to connect where as the number of users at that time may be even smaller than previously. In that case we need to shutdown the Oracle Server and Startup again. The problem gets solved.
Solution is required to permanenlty fix the the problem. Shutting down the Oracle Database and running again is not the soltution.
Network Monitoring is essential to ensure that computer systems and network devices are running. Use PRTG to monitor LANs, servers, websites, applications and devices, bandwidth, virtual environments, remote systems, IoT, and many more. PRTG is easy to set up & use.
Checking the Alert Log in AWS RDS Oracle can be a pain through their user interface. I made a script to download the Alert Log, look for errors, and email me the trace files. In this article I'll describe what I did and share my script.
Using SQL Scripts we can save all the SQL queries as files that we use very frequently on our database later point of time. This is one of the feature present under SQL Workshop in Oracle Application Express.
This video shows, step by step, how to configure Oracle Heterogeneous Services via the Generic Gateway Agent in order to make a connection from an Oracle session and access a remote SQL Server database table.
Using examples as well as descriptions, step through each of the common simple join types, explaining differences in syntax, differences in expected outputs and showing how the queries run along with the actual outputs based upon a simple set of dem…
