Oracle OpenWorld 2007 Presentations Available for Download

Hi,

For those who have missed OOW-2007 (like me), here is the chance to go through the presentations. Presentations are available on virtually all topics for download, but unfortunately, Tom Kyte's presentation is not downloadable.

Although there are many presentations available, I started reading Cary Millsap's "Why You Can't See Your Real Performance Problems" presentation.

Here is the link:

Moreover, the username and password to download the presentations are available at the top of the page for our convenience.

ORA-12537 TNS: Connection Closed

Dear readers,

When I was trying to establish client connection to one of our databases running on Oracle 10g, I received “ORA-12537 TNS: Connection Closed” error.

Upon investigation, I came across “TCP.VALIDNODE_CHECKING” parameter in “sqlnet.ora” file. This was set to “YES”. I simply commented this parameter and every thing went fine. Clients were able to establish connection to the database.

By setting TCP.VALIDNODE_CHECKING to “YES”, you inform Oracle database to allow/deny connections to the listed nodes. You may list the invited nodes using TCP.INVITED_NODES parameter in sqlnet.ora file or, alternatively, you may use the TCP.EXCLUDED_NODES parameter to disallow database connections from the listed nodes.

Hope you find this information helpful!!!

Manually Install/De-Install Database Options in Oracle Database 10gR2

Hi,

When a new database is created using DBCA, by default some of the common database options are installed like Oracle JVM and Oracle Text. But, when you manually create the database none of them get installed. You need to manually install them.

I thought of sharing Metalink Note Id’s for some of the Common Database Options which you can manually install/de-install once database has been created:
