Connectors Oracle Database

Oracle Database data integration with Lima, in both directions.

Oracle Database sits under Oracle EBS, JD Edwards, PeopleSoft and many custom systems. Lima reads it in parallel partitions over JDBC within an agreed connection cap, picks up changed rows by last-update columns and, where the DBA enables supplemental logging, reads changes with LogMiner. Oracle is also loaded as a target.

How Oracle Database fits the six Backbone steps. It is a source and a target: data comes out through the methods below, and results go back in with confirmation.

How Lima reads and writes Oracle Database

Method by method.

Each method has a job. The first load uses the bulk method; the daily run uses the incremental or change-capture method; write-back uses the interface the system itself uses.

MethodWhat it doesWhen it is used
Partitioned JDBC readsReads in parallel slices within a connection cap.First loads and history.
Last-update column deltasReads changed rows.Nightly deltas.
LogMinerReads the change log.Low-lag capture.
Direct-path loadsBulk loads targets.Oracle as a target.
What it covers

Objects and patterns.

The objects are the tables, views or records Lima reaches through the methods above. The patterns say how a copy is made and kept current.

Prerequisites, then four steps.

The prerequisites are what the team that runs Oracle Database grants. The four steps are the same for every connector.

  • A user with SELECT on the schemas
  • Supplemental logging and LogMiner grants for change capture
  • Connection cap agreed with the DBA
Register the connectionEndpoint, credentials from the vault, and the method. The connection is tested and a failed test names the cause.
Choose the objects and the patternPick tables or objects from the discovered schema, and the pattern: full, incremental, change capture or streaming.
Run the first load with checks onEvery row is valid or becomes an exception with an owner. The run ends with a count and a control total per table.
Schedule it on the business calendarA run window with a deadline; pause, resume and replay if a check trips; the report after every run.
What happens to a bad record

Incoming data = valid records + exception records. A row that fails a check is kept, routed to the person who owns it with a deadline, and replayed once fixed. The load carries on with the valid rows and the report says exactly what was held back. How exceptions work →

Plain meanings.

ConnectorA packaged way to read or write one kind of system, with its authentication, methods and prerequisites described.
Full, incremental, change capture, streamingFour ways to make and keep a copy: read everything; read what changed since last time; read changes from a log as they happen; consume events in small batches.
Write-backWriting a result into the system that owns it through its released interface; the system's response is the confirmation.
Control totalThe sum of a key amount column compared between source and target, along with the row count, at the end of a run.
Exception recordA row that failed a check: kept, routed to an owner, replayed once fixed.
Questions

Asked about this connector.

Does Lima install anything in Oracle Database?

Lima connects from outside through the interfaces listed above with credentials your administrators grant. Where a vendor requires its own agent or add-on for a method, the prerequisites say so.

How is load on Oracle Database kept in check?

Parallel reads are capped and the cap is agreed with the team that runs the system. Large reads run inside an agreed run window. Change capture keeps the daily volume small.

What do we see when a run finishes?

A report per run: rows in, rows out, control totals and variance per table, the exceptions held back and who owns them, and whether the deadline was met.

Can we start small?

Yes. Most estates start with one source, one target and one dataset, then add tables and patterns on the same connection.

A trial connects this system, runs a first load and ends with a reconciliation report. Your administrators see the prerequisites before anything is installed.
