-/**
- * This sample code demonstrates the functionality of Multi-tenant shared pools.
- * With the use of shared pools now it is possible for more than one tenant
- * datasources to share a common pool provided they are connecting to the same
- * database with a single url. To use shared pool functionality, all the tenant
- * datasources accessing shared pools should be defined in UCP XML configuration
- * file along with the pool properties. The code example shows how to get a
- * connection from a shared pool defined in xml.
- * 
- * The shared pool defined in sample XML config file has only one connection and
- * both the tenant datasources -tenat1_ds and tenant2_ds are reusing the same
- * connection to get the employee data from respective employee tables
- * (tenant1_emp and tenant2_emp) present in tenant1 PDB and tenant2 PDB.
