Siebel Data Warehouse 7.7 Product Changes and Customization Impacts

The changes in Siebel Data Warehouse mainly involve performance enhancements. Included are enhancements in the areas of change capture, reorganization of data, new data elements (like mini dimension), streamlining Informatica mappings, and so on. Your previous customizations may be affected by these changes. In these cases, reworking may be required to make sure that the customizations still function after the data warehouse is upgraded.

In addition to these enhancements, a new tool called the Data Warehouse Application Console (DAC) has been provided to efficiently manage Informatica sessions. All custom Informatica sessions need to be registered and managed using the DAC.

See the following list to identify whether user customizations will be impacted:

• All custom data warehouse tables, indices, and Informatica sessions will need to be registered with the DAC.
• Any reference to image tables (change capture mechanism).
• Any reference to the following data warehouse tables:
  • W_MAP_DIM
  • W_ORDERITEM_F
  • W_QUOTEITEM_F
  • S_ETL_SRC_TABLE
  • S_ETL_I_IMAGE
  • S_ETL_R_IMAGE
• Any reference to existing aggregates.

After the customization impact is determined, an upgrade plan needs to be formalized for making the necessary changes. See Siebel Data Warehouse Upgrade Customizations for procedures.
