The implicit connection caching feature supports the caching of XA connections. Tofiq 5 13 We have to wait for a reply from the Patent Office before getting final approval, so please be patient. Have a safe and happy time during this period, and we’ll see you all in ! The other 3 nodes receive connections as well, but strangely enough they are not evenly distributed. I know you’ve got these scattered all over the place, in presentations and whatnot, but for the basic ones: Whilst you are here, check out some content from the AskTom team:

It will require the installation of the Oracle8 client on the machine with the tomcat engine. The driver supports only JDK 1.

Because Oracle Database enforces the Java security model, a check is performed for a SocketPermission object. First, I modified your program to execute the test using 4 different possible scenarios for inserting data.

From the server standpoint there is not difference between the two. So, I a use sqlplus to flush the shared pool.

Oracle Database 10 g release 2 If you want your applet to connect thon a database running on a different computer, then you have the following options:.

I made it multi-user, just to show — just to prove for once and for all that using statements is a bad bad idea.


Java Programming with Oracle JDBC by Donald Bales

But, then we have to query the database each time. Sorry to bother you so much. The database component of Oracle JDeveloper uses the JDBC drivers to manage the connection between the application running on the client and the server. For SQL, direct bind is used up to Java characters and stream bind is used for larger. Shouldn’t it be closer or the same as the PreparedStatement? Is this still accurate for mdbc oci drivers?

This contains some useful info: The implicit cursor myth The prepared statement myth The hit-ration myth The separate index and table myth. Also, what would require to change if I do that – For eg. OK, so maybe it’s not a great difference.

Ask TOM “Selection of JDBC client side driver – Thin Vs OC”

Post as a guest Name. Pretty much the same but I log the timings to a database table so we can use SQL to analyze the results and parameterized it so we can use it over and over tthin recompiling each time: This bothered me so much — so so much, that I just had to followup again.


Thin Driver Performance August 05, – Stream bind of bytes setBytes: They also have different size limits, depending on the type of the SQL statement. This question is Whilst you are here, check out some content from the AskTom team: For code that runs in the database server acting as a middle tier, use the JDBC server-side Thin driver.

That tnin, the code runs and accesses data from a single Oracle session. This driver is useful in the following scenarios: BTW I work for Oracle and my group is responsible for the development of these drivers. We have to wait for a reply from the Patent Office before getting final approval, so please be patient.

February 15, – 3: Here I called the doStatement method 10x. Htin Tom, great explanations – thanks. Stream binding is slower, may require multiple round trips, and turns batching off. I can’t seem to find any mention of this in the Oracle docs or on Google. You can also give a tnsnames.
