Max. Connection & Connection Time out parameters

Hi,

This is a basic question regarding the connections while building a connection pool on oracle 8.1.7 database on solaris 8.

1. Is there any parameter in oracle (init.ora or some where else) which dictates the maximum no. of connections that ever can be opened from a database so that the java based connection pool can impose a limit on it's maximum pooled connection? If yes, then what is the parameter and how it can be tuned?
2. How to determine a connection time out property so that the java based connection pool manager can close the coonection before this time period.

Thanks in advance for your time and patience.

Regards,
