How to span DB transaction over whole BLT?

Hi All,

how to achieve transaction ACID properties regarding multiple DB connections over a full BLT? This would require to switch

off autocommit and reuse the same DB connection in serveral actions of the BLT and then issue a commit at the end.

Is this possible? Often we have the need to have transactional semantics of a BLT. Is it possible to leverage this via a custom

action? Is there access to the connection pool of MII from a custom action?

    The simple answer, Matthias, is no, but with custom actions, this would be quite easy to do. Ideally, you could have access to the MII connection pooling system, but if not, you could use JDBC directly to do the same thing. You would need to mirror the concept of the JCO transactions (Begin, Execute, Commit/Rollback), and the "magic" needed here is the ability to pass the database connection between these functions (in particular, the Begin action would create and own it, the others would act upon it).

    It would be much easier to do if you had the support of the MII team, and this would be a very natural enhancement request for the product.

      Hi, Matthias.

      I'm no longer with SAP, but I would suggest contacting Jeremy Good and/or Salvatore Castro at the SAP office in Exton for some assistance in obtaining the documentation and support you'll need, particularly if you are writing the actions for version 12.0, which represents a lot of internal changes to MII.
