7. The Pooling and Scalability tab will have properies that you can set for pooling

What just happened?
We have created a coniguraion using the HRSchema connecion for the clients to be able
to interact with the deployed applicaion modules. Whenever a coniguraion is created, we
will have a file named bc4j.xcfg to hold the informaion that has been provided for the
coniguraions. Each of the connecions and the coniguraion informaion is stored in this
ile along with other runime parameters used for pooling and high availability.

Have a go hero - explore the bc4j.xcfg file

Explore the bc4j.xcfg ile to know more about the coniguraions and properies
associated with each of the coniguraions.
