???????????Transaction?? - COMTI

• COMTI - COM Transaction Integrator
• Quickly generates COM wrappers for CICS, IMS
  transactions
• Enables easy MTS, COM application access to
  existing business logic
• Enables full transactional coordination between
  MTS and CICS, IMS transactions
• HIS 2000???
• XML document dispatch in addition to COM

35
????????COMTI ??

• COMTI wraps CICS and IMS transactions and
  exposes them asCOM objects. With COMTI,
  developers are quickly and easily able to
• Build n-tier applications that integrate MTS with
  IBM CICS and IMS transactions
• Build Windows applications which access host
  transactions without learning host programming
• integrate MTS via 2PC to maintain distributed
  transactional integrity

????????COMTI Automation Creation

1. Identify COBOL program
2. Import COBOL code into Component Builder
3. Click to create Type Library (.tlb file) with
   Component Builder
4. Drag and Drop the .tlb file into the MTS Package.

When the component is called, it invokes a CICS
or an IMS transaction and passes the input
parameters for processing..

• Replication
• Moving Like to Like or Mirroring
• Propagation
• Moving between dissimilar systems and/or data
  formats
• Transformation
• Alteration or transformation of the data from
  its original format

52
?????????? ?????
Microsoft SQL Server

• Snapshot Replication - Takes a snapshot of
  current data in a publication at a Publisher and
  replaces the entire replica at a Subscriber on a
  periodic basis.
• Incremental Replication - Distributes
  transactions to Subscribers as incremental
  changes are made.
• Merge Replication - Allows sites to make
  autonomous changes to replicated data, and at a
  later time, merge changes made at all sites.
  Merge replication does not guarantee
  transactional consistency.
