Replication support for HPSS feature

Technical Problem

Assume there is a partitioned tablespace and some parts are archived via HPSS. Therefore, there are archived and non-archived partitions.

Db2 transparent archive is not the case in this scenario. There is only one table with PBR Tablespace.

In V5, we do HPSS for that table. Some parts are archived. Then when we enable replication, the updates coming to non-archived partitions in Db2, will be replicated via CDC to IDAA

In V7, this does not work with CDC or Insync. Simply we can not enable replication after the archive process. So we can not replicate incoming updates for non-archived partitions to IDAA.

  • Future consideration
How should it work?

Business Impact

HPSS with IU capability is one of the powerful usecases to use IDAA as online archive for large partitioned tablespaces. We proposed this use case (Online Archive) with HPSS to several customers and with the added value of IU via CDC it became a near-realtime online archive platform. Unfortunately, we can not use this use case in V7.

Idea Priority Medium
Priority Justification This was working in IDAA V5 and without this capability we are loosing the capability of online arcive usecase with HPSS
