  • ISVs tailoring the Oracle Database to suit their needs

Languages, APIs, and applications that depend upon OCI:

  • Java applications using the OCI-based JDBC driver
  • PHP applications using the Oracle PHP adapter
  • Ruby/Rails applications using Oracle Ruby adapter
  • Python applications using Oracle Python adapter
  • Perl applications using Oracle Perl adapter
  • PL/SQL applications executing SQL
  • C++ applications using OCCI
  • C applications using the ODBC driver
  • VB applications using the OLEDB driver
  • .NET applications using the ODP.NET driver
  • Pro*C applications
  • Distributed SQL

OCI in Oracle Database 11g brings scalability, performance and diagnosability:

  • Database Resident Connection Pooling
  • Client side Result Cache
  • Runtime Connection Load Balancing
  • Binding and Defining Multiple Buffers
  • Prefetching of LOB data
  • Drop-in compatibility with 10g
  • Fault Diagnosability

OCI features in Oracle 10g include:

  • Unlimited size LOB support
  • High Availability Event Notification
  • Database DML/DDL Change Notification
