Limitations

The Replication Server DSI does not use bulk copy-in when:

• Autocorrection is on and the data is not part of subscription materialization.

• rs_insert has a user-defined function string.

• text column has a user-defined function string for rs_writetext with output none or rpc.

• The data row contains opaque datatype or a user-defined datatype (UDD) that has an rs_datatype.canonic_type value of 255.

• The data row contains an image or a Java datatype.

The bulk copy-in feature is not supported under the conditions listed below. In these instances, disable bulk copy-in.

• The replicate database is not Adaptive Server. In this case, if the DSI bulk copy-in is enabled, DSI terminates with an error message.

• The data size changes between Replication Server and the replicate Adaptive Server character sets, and the datarow contains text columns. In this case, if the DSI bulk copy-in is enabled, DSI terminates with this message:

  Bulk-Lib routine 'blk_textxfer' failed.
  Open Client Client-Library error: Error: 16843015,
  Severity 1 -- 'blk_textxfer(): blk layer: user
  error: The given buffer of xxx bytes exceeds the
  total length of  the value to be transferred.'
  

• The owner.tablename length is larger than 255 bytes and the replicate database is earlier than version Adaptive Server 15.0.3 Interim Release. If the DSI bulk copy-in is enabled, Replication Server terminates with this message:

  Bulk-Lib routine 'blk_init' failed.
  

  To specify not to use bulk copy-in when owner.tablename length is larger than 255 bytes:

  1. Turn trace on:

     trace "on", rsfeature, ase_cr543639
     

  2. Add this to the Replication Server configuration file:

     trace=rsfeature,ase_cr543639
     

Other limitations:

• Unlike the insert command, bulk copy-in does not generate timestamps; NULL values are inserted to the timestamp column if the timestamp column is not included in the replication. Either disable bulk copy-in, or set up your replication definition to include the timestamp column.

• Text and image columns are always logged, even if you change the writetext function string to no log.

• Bulk copy does not invoke insert trigger in Adaptive Server.

• The configuration parameter send_timestamp_to_standby has no effect on bulk copy-in. timestamp data is always replicated.
