These features are not supported with Oracle Connection Manager in Traffic Director Mode (CMAN-TDM) for all drivers.

  • Java Database Connectivity (JDBC) objects for Transparent Application Continuity (TAC)

  • Advanced Queuing (AQ)

  • Database Links

  • Database Startup or Database Shutdown calls

  • Sharding (or Oracle Globally Distributed Database)

  • SQL Translation

  • Dual session proxy authentication

  • OS authentication

  • Authentication as SYSDBA, SYSOPER, and so on

  • SSL external authentication (such as DN) without explicitly passing user name and password

  • Object REF

  • Session switching

  • Session migration

  • OCIObject* calls for navigational access

  • OCIPickerImage* calls

  • OCIAnyData* calls

  • OCISubscription* calls: Client-side subscriptions for Application Continuity (AC), TAC, Runtime Load Balancing (RLB), and Fast Application Notification (FAN)

  • OCILCR*, OCIXStream* calls

  • OCIStmtExecute:

    • Server-side scrollable cursor support

    • Implicit Results

  • Change Notification (CQN)

  • Client Result Cache

  • Database Resident Connection Pool (DRCP): Multi-property tag and PLSQL callback

  • OCIConnectionPool

  • Real Application Security (only in Java)

  • Bulk Copy (ODP.Net only)

  • Self-Tuning (ODP.Net only)

  • MultiThreadedServer (MTS) distributed transactions (ODP.Net only)

  • Oracle Advanced Security (ASO) encryption and supported algorithms (ASO only)

  • Usage of Application Context attributes

In addition, the following tasks are not supported:

  • Using SID instead of SERVICE_NAME in application-provided connect strings

  • Pipelining statement executions

  • Altering table's metadata

    This is because statements are always cached by CMAN-TDM.

  • Changing password with Proxy Resident Connection Pool (PRCP) connections

  • Application Continuity with Implicit Connection Pooling

    When connected to a TAC or AC service using PRCP or DRCP with Implicit Connection Pooling enabled, CMAN-TDM internally disables support for Application Continuity.
