Modifying column definitions to use the TIMESTAMP data type in an Oracle database
This content applies only to Pega Cloud environments
If you have an Oracle database and you use materialized interaction history summaries, modify the column definitions for DateTime properties to use the TIMESTAMP data type.
TIMESTAMP columns provide high-precision time to track customer responses by milliseconds. To store records with greater precision and to avoid duplicate data issues that might occur when you use DATE data type columns, convert the DateTime properties to make them map to TIMESTAMP columns.
Examples of DateTime properties include the following properties in the PR_DATA_IH_FACTinteraction history table:
- pxOutcomeTime
- pxDecisionTime

Update Guide
The Oracle database administrator performs this
task.
- Connect to the Pega Platform database.
- Modify the column definition for a DateTime property by running the following
ALTER script on the database:where:
ALTER TABLE <Schema_Name>.<Table_Name> MODIFY <Column_Name> TIMESTAMP<Schema_Name> is the name of the schema that contains the table. <Table_Name> is the name of the table that you want to modify. <Column_Name> is the name of the column whose definition you want to modify. - Save the underlying Data-Decision-IH-Fact Database Table rule.
