43. A Q & Q U E S T I O N S A N S W E R S

45. Best Practices - Connections Use connection pooling –Keep number of connections/connection pools to a minimum Watch out for dynamically-created connection strings –Changing parameter values does create new pools Use proxy authentication –Effective for uniquely-identified users with same roles Use Validate Connection only if you have to –Guarantees a valid connection, BUT extra round trip –Writing your own exception handler may be better/faster Close all ODP.NET objects when finished (e.g. OracleConnection) –Do not count on the garbage collector to do this automatically

46. Best Practices – Data Retrieval and Updates Key concept: control database roundtrips –Retrieve only the data that is needed when it’s needed Single command (SELECT) tuning –Use FetchSize (OracleDataReader) and RowSize (OracleCommand) to control result retrieval –Use DataAdapter Requery Save DB round trip and save from re-executing Multi-statement tuning (in one round trip) –Executing multiple, differing statements? Use anonymous PL/SQL Batches statements for execution in one round trip –Executing the same command multiple times? Use parameter array binding –Statement will execute once for each array value Use PL/SQL associative arrays for SELECT statements –Statement will execute once for the entire array

47. Best Practices – Data Types Key concept: control database roundtrips These benefits come from using ODP.NET types (e.g. OracleClob) Use OracleRefCursor class –Defers data retrieval until results needed Use Oracle LOB classes (DML) –No need to retrieve data when updating or writing to LOBs
