Oracle E-Business Suite Setup Guide

Follow our setup guide to connect Oracle E-Business Suite (EBS) to Fivetran.

Prerequisites

To connect Oracle EBS to Fivetran, you need:

Oracle 11g or above
IP (e.g. 1.2.3.4) or host (your.server.com)
Port (usually 1521)

Setup instructions

Allow access

Configure your firewall and/or other access control systems to allow incoming connections to your Oracle EBS database host and port (usually 1521) from Fivetran's IP.

Create user

Connect to your Oracle EBS database as an admin user.
Execute the following SQL commands to create a user for Fivetran and grant it permission to connect to your database. Replace <password> with a password of your choice:
```
CREATE USER FIVETRAN IDENTIFIED BY <password>;
GRANT CREATE SESSION TO FIVETRAN;
```

Grant read-only access

Note: Unless you wrap an identifier (schema name, table name, etc.) in double quotes, Oracle will convert it to upper case when it performs the operation.

Once the FIVETRAN user is created, grant it SELECT permission for each schema and table you want to sync:

GRANT SELECT ON "<schemaA>"."<tableA>" TO FIVETRAN;
GRANT SELECT ON "<schemaA>"."<tableB>" TO FIVETRAN;
GRANT SELECT ON "<schemaB>"."<tableC>" TO FIVETRAN;

Alternatively, you can grant access to all tables:

GRANT SELECT ANY TABLE TO FIVETRAN;

Grant the FIVETRAN user access to the DBA_EXTENTS, DBA_TABLESPACES, and DBA_SEGMENTS system views:
```
GRANT SELECT ON DBA_EXTENTS TO FIVETRAN;
GRANT SELECT ON DBA_TABLESPACES TO FIVETRAN;
GRANT SELECT ON DBA_SEGMENTS TO FIVETRAN;
```
We use these system views to optimize our initial import queries.

Incremental updates

To keep your data up to date after the initial sync, we use one of two built-in Oracle technologies: Flashback and LogMiner. Both Flashback and LogMiner keep a record of recent data changes, which allows Fivetran to update only the data that has changed since our last sync.

Choose either Flashback or LogMiner as your incremental update mechanism.

To enable Flashback, proceed to the next section.
To enable LogMiner, skip ahead to the LogMiner section.

Flashback PRIVATE PREVIEW

Flashback uses Automatic Undo Management to record all committed changes for each included table. To enable Flashback, follow these steps:

Grant the FIVETRAN user access to additional system views:

GRANT SELECT ON DBA_FLASHBACK_ARCHIVE TO FIVETRAN;
GRANT SELECT ON DBA_FLASHBACK_ARCHIVE_TABLES TO FIVETRAN;
GRANT SELECT ON V_$SYSTEM_PARAMETER TO FIVETRAN;
GRANT SELECT ON V_$DATABASE TO FIVETRAN;

Create a tablespace with enough space to store about 7 days’ worth of database changes.
```
CREATE TABLESPACE <tablespace> DATAFILE SIZE 1G AUTOEXTEND ON MAXSIZE <maximum size>;
```
Create a Flashback Data Archive with at least 1 day of retention (Fivetran recommends 7 days).
```
CREATE FLASHBACK ARCHIVE <archive> TABLESPACE <tablespace> RETENTION 7 DAY;
```

Add all tables you want to sync to the archive.

ALTER TABLE "<schema>"."<table>" FLASHBACK ARCHIVE <archive>;

Grant the FIVETRAN user permission to run Flashback queries on the tables you want to sync. You can either do this per table:
```
GRANT FLASHBACK ON "<schema>"."<table>" TO FIVETRAN;
```
or for all tables:
```
GRANT FLASHBACK ANY TABLE TO FIVETRAN;
```

Add an index to FDA-generated history tables (Optional)

Flashback queries are significantly more efficient with an index on the history tables generated by Flashback Data Archive. The addition of this index can make your sync significantly faster and more resource-efficient, especially if your database is large or has a high change volume. To add indices, follow these steps:

Find the system-generated history tables for each of your Flashback-enabled tables by running the following query:
```
SELECT TABLE_NAME, ARCHIVE_TABLE_NAME FROM DBA_FLASHBACK_ARCHIVE_TABLES;
```
For each of the ARCHIVE_TABLE_NAMEs returned in the previous query, add an index on the STARTSCN column:
```
CREATE INDEX <index-name> ON <archive-table-name> (STARTSCN);
```

LogMiner

LogMiner uses Archived Redo Log files on your Oracle database to get a list of modified tables and determine which rows need to be updated incrementally in the destination. Therefore, we require the following configuration to be present on your Oracle database:

If ARCHIVELOG mode is not enabled on your database, enable ARCHIVELOG mode.

Note: Enabling ARCHIVELOG mode requires the Oracle instance to be taken offline for a brief period. For more information, see Oracle's documentation.
```
SHUTDOWN IMMEDIATE;
STARTUP MOUNT;
ALTER DATABASE ARCHIVELOG;
ALTER DATABASE OPEN;
```
Configure Oracle RMAN to retain backups and archive logs for at least 24 hours (Fivetran recommends seven days):

Note: Fivetran must have a minimum of 3 hours' worth of log data to begin our initial sync. You cannot complete your Fivetran set up until 3 hours after RMAN has been configured to retain Archive Logs.
```
RMAN> CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;
```
We recommend setting DB_RECOVERY_FILE_DEST_SIZE to a value that agrees with your available disk space, since expired and obsolete log and backup files can quickly fill your disk. For more information, see Oracle's Documentation.
For each table you plan to sync, run the following query to enable extra supplemental logging:
```
ALTER TABLE "<schema>"."<table>" ADD SUPPLEMENTAL LOG DATA (PRIMARY KEY) COLUMNS;
```
For each table where the primary key is expected to change, run the following query:
```
ALTER TABLE "<schema>"."<table>" ADD SUPPLEMENTAL LOG DATA (ALL) COLUMNS
```
If you don't configure the logging data correctly, you will receive a warning when Fivetran encounters a primary key change. The warning will give you customized instructions.

Grant permissions for running LogMiner to the FIVETRAN user.

GRANT SELECT ON SYS.V_$DATABASE TO FIVETRAN;
GRANT SELECT ON SYS.V_$ARCHIVED_LOG TO FIVETRAN;
GRANT SELECT ON SYS.V_$LOGMNR_CONTENTS TO FIVETRAN;
GRANT EXECUTE ON DBMS_LOGMNR TO FIVETRAN;
GRANT EXECUTE ON DBMS_LOGMNR_D TO FIVETRAN;
GRANT SELECT ANY TRANSACTION TO FIVETRAN;
GRANT EXECUTE_CATALOG_ROLE TO FIVETRAN;

Grant additional permissions to the FIVETRAN user for Oracle version 12.
```
GRANT LOGMINING TO FIVETRAN;
```

Finish Fivetran configuration

Enter your chosen destination schema name in the connector setup form.
Enter the following information in the setup form:
- Host
- Port
- User
- Password
- SID
Choose a connection method.
Click Save & Test. Fivetran will take it from here and sync your data from your Oracle EBS account.
