Usage

  • rs_get_thread_seq_noholdlock is equivalent to rs_get_thread_seq, except that it is used when dsi_isolation_level is 3. It is executed only when more than one DSI thread is defined for a connection. The row select is done with the noholdlock option. The function returns a single row with a single column, <seq>, which contains the current sequence number for the specified ID.

  • The rs_get_thread_seq_noholdlock function has function-string class scope.

  • Replication Server creates an initial rs_get_thread_seq_noholdlock function string for the system-provided function-string classes during installation.

  • If you use a user-created base function-string class and you use the parallel DSI feature with transaction isolation level 3, create a function string for rs_get_thread_seq_noholdlock.

  • Create or customize an rs_get_thread_seq_noholdlock function string at the Replication Server that is the primary site for the class.
