Performance Tuning Tips

-

 Performance Tuning Tips:

--> Do not select all the columns when you are fetching data from FusionDB because it will do full table scan(FTS)

Instead use only required columns or Index columns.


---> Always limit the rows when fetching data.

--> Use Proper Joins(Primary Key and Foreign Key relationship).

--> Use Exists instead of IN.

--> Use Hints.

 What is incremental data? Incremental Data Loads ----------------------- If you are sending employee data to a third-party payroll provider on every Friday, we don’t want to send all employees instead we only want the ones who changed current week.

LAST_UPDATE_DATE tells us when the record was physically saved. */ --Examples: ------------------------------- select count(1) from ( Select  papf.person_number, ppnf.FULL_NAME from  per_all_people_f papf, per_person_names_f ppnf WHERE 1=1 and papf.person_id=ppnf.person_id  and papf.LAST_UPDATE_DATE >=sysdate-7 --(Incremental) and ppnf.NAME_TYPE='GLOBAL' and sysdate between papf.EFFECTIVE_START_DATE and papf.EFFECTIVE_END_DATE and sysdate between ppnf.EFFECTIVE_START_DATE and ppnf.EFFECTIVE_END_DATE ) Result:  55 Records(Only Changed Records in current week) --------------------------------- select count(1) from ( Select  papf.person_n...

Mastering Parameters in Oracle Fusion BI Publisher

Mastering Parameters in Oracle Fusion BI Publisher: Mandatory, Optional, and "All" Logic When building Data Models in Oracle Fusion, how you handle parameters determines the user experience and report performance.

Optional Parameters (The "All" Logic) Use this to allow users to leave a field blank or select "All" to see all records. Syntax (Recommended):  AND (:parameter IS NULL OR column = :parameter) Example: AND (:p_Person_Number IS NULL OR Person_Number = :p_Person_Number) Note: Using NVL is common but can be slower on large datasets as it may bypass indexes. 3. Multi-Select Parameters Use this when the user can select multiple values from a list. Syntax: AND (column IN (:parameter) OR 'All' IN (:parameter)) Example: AND (Person_Number IN (:p_Pe...
