what is a 10g alternative to Database Resident Connection Pooling?

Our developers have created an application that generates up to 300 independent C++ programs each of which establishes their own connection to the database and when they fail abnormally this number can easily double or triple causing session limit issues.  Since I'm assuming the connection pool can't be shared across these programs, without having the application redesigned, is there any 10g database alternative to DRCP?  I see that DRCP is an 11g feature:  http://docs.oracle.com/cd/E11882_01/server.112/e17120/manproc002.htm
