137. Your database  instance  is currently configured  to support 1,500 connections. The Web application
that uses the database allows a large number of users to work with the database simultaneously. Some
users of the Web application do not interact with the server all the time.  
You want to increase the scalability by configuring the database instance to handle more connections. As
a DBA, which configuration would you set to support more than 1,500 connections at a time?
A.You would configure more listeners for the database.
B.You would configure the database in shared server mode to use the connection pooling feature.
C.You would increase the value of the PGA_AGGREGATE_TARGET initialization parameter that assigns
more session memory to users.
D.You would decrease the value of the PRIVATE_SGA resource limit in the profiles used by the users to
accommodate more session information.
Answer: B

连接数太多，用shared server mode， 不过一般都用中间件不直接连库了。所以用shared server mode的也不多。         版权声明：本文为博主原创文章，未经博主允许不得转载。
