Oracle ODI 12c Multi-table federated query and timed task settings

This article describes how to make multi-table federated queries and set up scheduled tasks through ODI. The preparatory work is as follows:

• Prepare physical and logical solutions;
• Create the model and synchronize the scheme by "reverse engineering";
• Create projects (create or use existing ones based on the actual situation);
• Ensure that both the source and destination tables have a primary key present.
  The first three points above can be found in the relevant articles in my blog. One, Preparing1.1 source SQL statement

  SELECT a.ID,   a.ORG_ID,   a.NAME_ID,   a.EVR_ID,   a.PACKAGE_ARCH_ID,   a.PACKAGE_GROUP,   a.RPM_VERSION,   a.DESCRIPTION,   a.SUMMARY,   a.PACKAGE_SIZE,   a.PAYLOAD_SIZE,   a.INSTALLED_SIZE,   a.BUILD_HOST,   a.BUILD_TIME,   a.SOURCE_RPM_ID,   a.CHECKSUM_ID,   a.VENDOR,   a.PAYLOAD_FORMAT,   a.COMPAT,   a.PATH,   a.HEADER_SIG,   a.COPYRIGHT,   a.COOKIE,   a.LAST_MODIFIED,   a.CREATED,   a.MODIFIED,   a.HEADER_START,   a.HEADER_ENDFROM rhnpackage a LEFT JOIN web_customer b ON a.org_id = b.IDWHERE a.name_id > 5 AND a.package_group = 4;

  1.2 Creating mappings
• Drag the related table in the model source database to the mapping box;
• Insert the join and filter in the component bar in the Map box, and set the relevant connection according to the SQL;
• Push the related tables in the model target database to the Map box and set up the related connections. As shown in the following:
  1.2.1 Setting up joins

  In the logical structure of the map, click the connection icon, in Condition, enter "Join Condition" and "Join Type" and click Save. As shown in the following:
  

  1.2.2 Setting Filter

  In the logical structure of the map, click the filter icon, in Condition, enter "Filter Condition", click Save. As shown in the following:
  

  1.2.3 Setting the target table consolidation type

  In the logical structure of the map, click on the target table, set "target" of "integration Type" as "Incremental Update", click Save. As shown in the following:
  

  1.2.4 Set the Knowledge module for the target group

  In the physical structure of the mapping, the Knowledge module for setting up the AP is "LKM SQL to SQL (built-in)." GLOBAL ", click Save. As shown in the following:
  
  In the physical structure of the shot, set the knowledge module of the target table to "IKM Oracle Incremental Update" and click Save. As shown in the following:
  

  1.3 Validating mappings

  Click on "√" to verify it as shown in:
  

  Second, Scheduling2.1 generation scene

  Right-click on "Map Name" and select "Generate Scenario ..." as shown in:
  
  The scene name and version number are customized as shown in:
  

  2.2 Scheduled Task settings

  Expand the scene, right-click scheduling, select "New scheduling", and define the automatic scheduling time according to the actual situation. This is the day of the afternoon 16:00 start to run. Such as:
  
  Finally, update the agent's scheduling information to see the job information that is about to run, as shown in:
