I found that restarting the server is the only way to free up the pool connections. Or am I getting the relationship between sessions and and connections completely wrong? On the other hand, stored procedures allow for better security, better instrumentation, more reuse, easier maintenance, etc. After this I tried to use it in Tomcat but I was not successful at this. Tom: I hope you enjoyed your vacation last 10 days! You could create another user to do so, or shutdown your apps and start them again and establish policies for this. If so, how to do that - that is what I want to know.
There are no new connections created or reauthentications. This happens at point 1 in the above image. In fact, probably won't be recreated until an application restart. That user would have a connection and a session established and when the application grabbed a connection from the pool - it would create a new session in that connection - connecting through to the real user - and do whatever it needs and then uncreate that session. If we did not see any errors in the database, where is coming from? Thanks for the kind support! How can we reduce or prevent pool fragmentation? It will disrupt al the users on your application whenever a pool member comes up. The connection timeout on app server is 60 minutes which means that after 60 minutes of inactivity, a connection would be dropped. Are the results cached or just the query? Is there any way to reset the connection pooling automatically if there is a node switch due to cluster fail-over? When tracing such an application, the required trace output can be scattered through many files.
So my user requests a look at the view, and displays it to the web page. If you create the pool yourself in your application, you have full reign over it. Do yourself a favor and use the connection pool when connecting to a remote system. Thank you for the detailed reply. Connection pooling was not setup currently. This would have the effect of speeding up the emptying out of now invalid connections.
I think the Audit Logout is called because connection pool is going to reset the current connection to reuse it. Now where have I heard that idea? After making the class make jar file of it and copy it to Tomcat. This may have occurred because all pooled connections were in use and max pool size was reached. You write software Writing software involves. Another solution which again avoids the issue is to try and force the application to use a dedicated server process. Yogesh, If you have written your own connection pool, write your own PreparedStatement cache too. When the client-side code requests a connection close or even connection dispose , the connection is not removed from the pool, log out does not occur on the server.
You generate the page, format the html whatever -- and then return the connection to the pool where someone else can use it. Once a child process is freed at the end of a different request, the connection will then be serviced. Or am I confusing session with connection? Fortunately, there is a relatively simple way to avoid this side effect. As an aside, you are using the default fetch size of 10, whereas Tom recommends 100. And being an engineer at , I can only recommend my craft — and find out whether any of your end users suffer from or not.
You cannot have millions of users fetching simultaneously from a single database - it would not work. The shared server configuration was introduced to allow you to squeeze on a few more concurrent users in a client server configuration. The procedure uses 2 separate global temp tables and an execute immediate to copy the contents from one gtt into the other gtt. And yes, I am setting a test of this. I do not have access to web logs. A connection to the database may or may not have a dedicated process.
I thought connection pooling is enabled by default. For eg: In my connection string I have master database. Open the above attempt for SqlConnection. Since you are creating a connection pool in your application for your application's own use, Tomcat doesn't need to know about it. Thanks a lot for this. The test script they created, does the following Loop 1000 times 1. Do i need to to look at the web server log to see who originated those? My question is why did I have to do that? On thi page, user would be able to set path to the database.
These servers issue connections to the databases in a distributed manner to balance the web application load. If the user clicks the same button again for that function - data insertion and display, data gets double in that temporary table. Shared server introduces considerable overhead to the process of performing sql if you want the details on why that is, Expert Oracle Database Architecture spends some time on it. Connections are pooled according to the connection string plus the user identity. It would then require another connection to do the update. The connection pool connects to the warehouse node of the rac.
