Connection Pools – Best Practices

Most of the times not much thought is given to defining connection pools while developing rpd. Improperly defined connection pool would affect the OBIEE performance and user experience. Here are some of the things to consider while defining connection pool.

  • Change the default maximum connections. The default is 10. Based on your system usage change the value that is more realistic to your system usage
  • Create a separate connection pool for execution of session variables
  • Create a separate connection pool for the execution of aggregate persistence wizard. Remember that you need to give the schema user owner credentials for this connection pool as the wizard creates and drops tables
  • If need be create a separate connection pool for VVIPs. You can control who gets to use the connection pool based on the connection pool permissions.

  1. Hi Kumar,

    Thanks a lot of the information on the blog.keep up the good work.

    I have a question, Is it possible to import the tables from two diff data bases.

    For eg: If i want to import the data from Oracle and another from Tera data. Is it possible to work arround this kind of scenario.

    Thanks In Advance.

  2. Yes, you can import tables from two different kinds of databases. They will have their own connection pool.
