System-provided classes

Several function-string classes are provided with Replication Server. These are called system-provided classes.

• rs_sqlserver_function_class – default Adaptive Server function strings are provided for this class. The default function strings in rs_sqlserver_function_class are identical to those in rs_default_function_class. rs_sqlserver_function_class is assigned by default to Adaptive Server databases you add to the replication system using rs_init.

  You can customize function strings for this class. However, this class cannot participate in function-string class inheritance. In most cases, using derived classes that specify rs_default_function_class as a parent class is preferable to using rs_sqlserver_function_class directly.

• rs_default_function_class – default Adaptive Server function strings are provided for this class. The default function strings in rs_sqlserver_function_class are identical to those in rs_default_function_class.

  You cannot customize function strings for this class. However, this class can participate in function-string class inheritance. In most cases, using derived classes that specify rs_default_function_class as a parent class is preferable to using rs_default_function_class directly.

  The system-provided function-string classes rs_default_function_class and rs_sqlserver_function_class contain default function strings for all system functions except rs_dumpdb and rs_dumptran. If you need to use function strings for these functions you must create them yourself in a derived class or in rs_sqlserver_function_class.

• rs_db2_function_class – DB2-specific function strings are provided for this class. See “Creating class-level translations,” in Chapter 9, “Managing Replicated Tables” in the Replication Server Administration Guide Volume 1 for more information about using this class.

  You cannot customize function strings for this class. If you require DB2 function strings, using derived classes that specify rs_db2_function_class as a parent class is preferable, in most cases, to using this class directly.

• rs_mss_function_class – Microsoft SQL Server function strings are provided for this class. You cannot customize function strings for this class. See “Creating class-level translations,” in Chapter 9, “Managing Replicated Tables” in the Replication Server Administration Guide Volume 1 for more information about using this class.

• rs_oracle_function_class – Oracle function strings are provided for this class. You cannot customize function strings for this class. See “Creating class-level translations,” in Chapter 9, “Managing Replicated Tables” in the Replication Server Administration Guide Volume 1 for more information about using this class.
