SAP Replication Server System Functions

SAP Replication Server translates commands from the primary database into SAP Replication Server functions that represent data server operations such as insert, delete, select, begin transaction, and so on. It distributes these functions to remote SAP Replication Servers in the system, where they execute those operations in remote databases.

• rs_autoc_on
  Updates the rs_status table to indicate that autocorrection has been set to on.
• rs_autoc_off
  Updates the rs_status table to indicate that autocorrection has been set to off.
• rs_autoc_ignore
  Updates the rs_status table to indicate that autocorrection has failed and that DML is ignored for a table.
• rs_batch_end
  rs_batch_end allows users to batch commands into non-Adaptive Server database servers. This function string stores the SQL statements needed to mark the end of a batch of commands.
• rs_batch_start
  rs_batch_start allows users to batch commands into non-Adaptive Server database servers. This function string stores the SQL statements needed to mark the beginning of a batch of commands.
• rs_begin
  Begins a transaction in a data server.
• rs_check_repl
  Checks to see if a table is marked for replication.
• rs_commit
  Commits a transaction in a data server.
• rs_datarow_for_writetext
  Provides an image of the data row associated with a text, unitext, or image column updated with the Transact-SQL writetext command, with the Client-Library function ct_send_data, or with the DB-Library™ functions dbwritetext and dbmoretext.
• rs_ddlsession_setting
  Automatically applies several Adaptive Server session-level set options to support the replication of Adaptive Server precomputed result set DDL commands.
• rs_ddlsession_resetting
  Automatically resets several Adaptive Server session-level set options to the default values after the replication of Adaptive Server DDL commands.
• rs_delete
  Deletes a row in a replicated table.
• rs_dsi_check_thread_lock
  Determines whether or not the DSI executor thread is holding a lock that blocks a replicate database process. A return value greater than 0 indicates that the thread is holding resources required by another database process, and that the thread should roll back and retry the transaction.
• rs_dumpdb
  Initiates a coordinated database dump.
• rs_dumptran
  Initiates a coordinated transaction dump.
• rs_get_charset
  Returns the character set used by a data server. This function allows Replication Server to print a warning message if the character set is not what is expected.
• rs_get_errormode
  Returns native error configuration, which determines whether or not the native error is returned directly from the replicate server.
• rs_get_lastcommit
  Returns rows from the rs_lastcommit system table.
• rs_get_sortorder
  Obtains the sort order used by a data server. This function returns a warning message if the sort order does not match that of the Replication Server, and if the sort order is not what is expected.
• rs_get_textptr
  Retrieves the description for a text, unitext, or image column.
• rs_get_thread_seq
  Returns the sequence number for the specified entry in the rs_threads system table.
• rs_get_thread_seq_noholdlock
  Returns the sequence number for the specified entry in the rs_threads system table, using the noholdlock option.
• rs_initialize_threads
  Sets the sequence of each entry in the rs_threads system table to 0.
• rs_insert
  Inserts a single row into a table in a replicate database.
• rs_marker
  Passes its parameter to Replication Server as an independent command.
• rs_non_blocking_commit
  Requests data servers to immediately send a positive response to a COMMIT statement without waiting for transactions to be written to disk.
• rs_non_blocking_commit_flush
  Sends an insert, delete, or update command to the data servers so that transactions that were sent through a connection configured with rs_ non_blocking_commit are saved to disk.
• rs_raw_object_serialization
  Enables Replication Server to process Java columns in serialized format.
• rs_repl_on
  Sets replication on in Adaptive Server for either a database connection or database connections.
• rs_repl_off
  Specifies whether transactions executed by the maintenance user in the Adaptive Server database are replicated.
• rs_rollback
  Rolls back a transaction. This function is reserved for future use.
• rs_select
  Selects rows for subscription materialization from the primary copy of a replicated table and, for subscription dematerialization, from the replicate copy of the table.
• rs_select_with_lock
  Selects rows for subscription materialization from the primary copy of a replicated table, using a holdlock to maintain serial consistency.
• rs_session_setting
  Sets SAP IQ parameters and database options for the duration of the connection to the SAP IQ replicate database.
• rs_set_ciphertext
  Enables replication of encrypted columns to an Adaptive Server table.
• rs_set_dml_on_computed
  Enables the replication of materialized computed columns to the replicate Adaptive Server database as regular columns.
• rs_set_isolation_level
  Passes the isolation level for transactions to the replicate data server.
• rs_set_quoted_identifier
  Configures a data server connection to accept quoted identifiers.
• rs_set_timestamp_insert
  Enables replication of timestamp columns to an Adaptive Server table.
• rs_setproxy
  Changes the login name in a data server.
• rs_sqldml
  A replicated function that carries SQLDML to Replication Server.
• rs_textptr_init
  Allocates a text pointer for a text, unitext, or image column.
• rs_ticket_report
  Insert ticket to the rs_ticket_history table.
• rs_triggers_reset
  Turns off triggers in Adaptive Server and Oracle.
• rs_truncate
  Truncates a table or a table partition in a replicate database.
• rs_update
  Updates a single row in a table in a replicate database.
• rs_update_threads
  Updates the sequence number for the specified entry in the rs_threads system table.
• rs_usedb
  Changes the database context in a data server.
• rs_writetext
  Modifies text, unitext, or image data in a replicate database.
