It is recommended that you check this document prior to beginning this install by querying under Solutions/FAQs for the FAQ 1-18571IL.

  16. Overview of Materialized View Framework

  17. Materialized View Framework • Materialized Views in the ODS • One for One Replication of Banner source tables in the ODS • Initial load of data when creating the Mview • Each Mview is setup using FAST REFRESH option • FAST REFRESH uses Primary Key if available, otherwise uses ROWID • Setup at creation of mviews • Materialized Views used as the source of the ODS ETL • Core ODS ETL stays the same (triggers, change tables, composite tables, reporting views) • Refresh of ODS now includes 2 types of refreshes • Mview refresh (new) • ODS Composite Table refresh (existing) • Mviews do not support LONG columns

  22. Materialized View Framework • Database Link Setup • Can be setup to create one PUBLIC DB link or multiple PRIVATE dblinks • Defined in login.sql as parameter STAGING_MV_LINK_TYPE using values: PRIVATE or PUBLIC • Public dblink between ODSSTG schemas in source and ODS databases • Private dblinks between product schemas in ODS database and ODSSTG schema in source database

  25. Materialized View Framework • Initial Creation of Materialized View (Source side) • Materialized View Log and Internal Oracle trigger placed on each Banner table in which an mview is being created for in ODS • Needed for FAST REFRESH • If there is an existing Mview Log on the Banner table, ODS will utilize that log • Have broken out creation of Banner side logs to minimize time Banner has to be placed in RESTRICTED mode • No performance impacts of these items on Banner

  26. Banner Database ODS Database SPRIDEN SATURN SATURN MLOG$_SPRIDEN Internal Trigger Public DBLINK ODSSTG ODSSTG

  27. Materialized View Framework • Initial Creation of Materialized View (ODS side) • Materialized View is created in the ODS in the same replicated product schema • New package in ODS called MGKMVEW to house all mview related procedures • Similar to MGKSTRM built for Oracle Streams • MGKMVEW.P_STAGE_MVIEW • Creates each mview structure • Loads the data • Specifies FAST REFRESH on PK or ROWID • Builds indexes based on the Banner source table • Once Mview is initially staged, the baseline ODS trigger is put on it to use for ODS Composite Table refresh

  28. Banner Database ODS Database SPRIDEN’ SPRIDEN Initial mview create & load SATURN SATURN MLOG$_SPRIDEN ST_SPRIDEN_INSERT_ODS_CHANGE Internal Trigger Public DBLINK ODSSTG ODSSTG

  29. Materialized View Framework • Materialized View FAST REFRESH • As data changes occur in Banner, those records are logged in the Mview logs for that Banner table • Logged with ROWID data or PK data • When Mview is FAST REFRESHed, only the records from the mview log in Banner are applied to the ODS mview to keep the data between the source and target in sync • Source and target are not updated automatically (like Streams). An explicit command to refresh the Mviews is required • Logs are cleared out once Mview refresh has been completed successfully (or after all mviews using that log have been refreshed)

  32. Materialized View Framework • Materialized View Refresh Groups • A Refresh Group is a grouping of materialized views to be refreshed at the same time. This ensures data is captured for each Mview refresh at a specific point in time • Delivered refresh group are broken into 2 groups per product schema • 1 group for Validation tables • 1 group for all other tables • Example: Refresh Groups for ODS General are: • ODS_REFGROUP_GENERAL • ODS_REFGROUP_GENERAL_VAL • Mviews in the delivered Refresh Groups can be reorganized using command line API calls from our delivered packages • An Mview can only exist in 1 Refresh Group

  33. Materialized View Framework • Materialized View Staging Collections • A Staging Collection allows you to group Refresh Groups together. • Staging Collections are stored as parameter records in MTVPARM under the INTERNAL_GROUP = STAGING REFRESH COLLECTION • Delivered Collections • 1 per product area • Each Collection contains the 2 delivered Refresh Groups per product • Example: Collection: REFRESH_GENERAL contains: • ODS_REFGROUP_GENERAL • ODS_REFGROUP_GENERAL_VAL

  34. Materialized View Framework • Materialized View Staging Collections • Since the refresh of the Mviews should happen prior to the regular ODS refresh, each Collection is delivered and set up to be run with the associated ODS ETL refresh of the Composite tables. • These 2 jobs are tied together in MTVPARM as shown below • Example: • Collection: REFRESH_GENERAL • ETL Refresh: REFRESH_GENERAL • When REFRESH_GENERAL is run, it will refresh the GENERAL Mviews and then refresh the GENERAL ODS Composite tables • REFRESH_ALL will refresh all of the MVIEWS first, then run the ODS Composite table refresh
