This chapter contains the requirements when capturing from an Oracle source database and replicating to a supported target database.
Prerequisite: At least the minimum level of supplemental logging must be enabled. Some SharePlex features may require PK/UK supplemental logging to be enabled.
SharePlex supports replication from Oracle to Oracle, according to the details below.
The following operating systems are supported for capture from a supported Oracle database and replication to an Oracle target database. For a list of supported source and target databases for Oracle capture, see Supported Oracle Source and Target Versions.
SharePlex supports only the 64-bit version of the listed operating systems.
Note: SharePlex supports the following operating systems and only where the version matches the Oracle certified platforms. For example, Oracle 19c supports Linux 7 and later, therefore installation of SharePlex on a system with Oracle 19c is supported only on Linux 7 and later.
Note: SharePlex supports remote replication for the Solaris 11.3 platform when the database is running on Solaris 11.3 and SharePlex is on a Linux platform.

SharePlex supports replication from Oracle to Kafka, according to the details below.
Apache Kafka 0.8.x, 0.9.x, 0.10.x, 0.11.x, 1.0.x, 1.1.x, 2.0.x, 2.1.0, 2.3.1, 2.5.0, and 3.0
Linux: When replicating data to the Kafka (Apache and Confluent) target, target SharePlex should be installed only on the Linux platform.
We test and reproduce issues against:
Apache Kafka
Confluent Kafka
Note: If you would like to use a different vendor who provides their own Kafka distribution or provides a Kafka-compliant interface, you are welcome to do so. From a support perspective, our support and development teams will share any Kafka broker errors that SharePlex receives and also ensure SharePlex itself is working properly to capture data, the target configuration formats in SharePlex are correct, and the SharePlex poster is posting or attempting to post according to the Kafka versions under support. If there are SharePlex issues with Kafka support that can be reproduced on Apache Kafka or otherwise demonstrated to be definitely associated with SharePlex, our team will address those as standard Kafka issues.

Replication of LOB operations generated by dbms_lob are not supported when replicating to non-Oracle targets.
SharePlex supports DML operations on tables and sequences, with some conditions. DML can be replicated from an Oracle source to an Oracle target or an Open Target target.
Note: Replication to targets with a different character set is supported, with limitations. When posting to Open Target databases, XML files and JMS, SharePlex supports only UNICODE and US7ASCII on the target, but conversion can be performed by an Oracle client installed on the target system. For full details, see the Preinstallation Checklist in the SharePlex Installation and Setup Guide for an Oracle Source.
SharePlex supports the following DML operations on tables:
Direct-path loads (SQL*Loader) (INSERT AND FULL ROLLBACK).
Note: Replication of partial rollbacks of DLOADs is not supported.
The target table must support the column types that are being replicated from the source Oracle table.
SharePlex supports the following table types for DML operations:
|
Supported table type* |
Conditions of Support |
|---|---|
|
Regular Oracle tables |
None |
|
Index-organized tables |
SharePlex does not support:
|
|
Partitioned tables |
None |
|
Views |
None |
|
Materialized views |
SharePlex does not support replication from a materialized view to a materialized view. SharePlex can replicate the underlying table of a materialized view to a regular target table. |
SharePlex does not support the following table types:
*SharePlex does not support the following for any table type:
SharePlex supports DML operations on secured or compressed objects as described in the following table. See "Conditions of support" following this table for additional information.
| Secured/Compressed Object | Can be replicated to: | |
|---|---|---|
| DML on tables encrypted by Oracle Obfuscation Toolkit | All target types | |
|
DML on tables with Transparent Data Encryption (TDE)1 |
All target types | |
|
DML on Oracle Label Security (OLS)2 |
All target types | |
|
DML on compressed objects: Basic, Advanced Row (OLTP) Compression, HCC3 |
All target types | |
|
Direct Load (DLOAD) on compressed objects: Basic, Advanced Row (OLTP) Compression, HCC3 |
All target types |
1. Conditions of support - TDE
SharePlex supports Tablespace Encryption and Column Encryption, both source and target.
The SharePlex copy/append command does not support TDE.
TDE is not supported for sources on RDS.
SharePlex only supports the AES and DES encryption algorithms.
2. Conditions of support - OLS
By default, SharePlex cannot process rows that are protected by OLS (Oracle Label Security) because users granted DBA privileges (like SharePlex) do not have enough privileges to access those rows. However, if privilege is granted from the OLSSYS user, SharePlex can support OLS. SharePlex was tested under the following OLS configuration:
Note: If the OLS policy data label column is defined as hidden, the data in that column cannot be replicated by SharePlex.
3. Conditions of support - compression
For HCC compression: SharePlex does not support query low compression. Supported types of compression are query high, archive low and archive high.
For Advanced Row (OLTP) Compression: Under certain conditions, Oracle does not provide enough information in the redo log for SharePlex to replicate a DML operation on a OLTP compressed object. Testing of OLTP compressed objects is advised.
SharePlex provides default and optional DDL support.
Note: Support for DDL on compressed Oracle objects is limited to the following:
SharePlex does not support:
This section outlines both default and optional DDL support.
SharePlex supplies default and optional DDL replication for objects whose names are listed in the configuration file explicitly or by wildcard. See "Conditions of support" following this table for additional information.
For details about the controlling parameter, see the SharePlex Reference Guide.

For CREATE MATERIALIZED VIEW the following applies:
To replicate sequences, the supplemental logging of primary and unique keys must be enabled at the database level, or you must enable supplemental logging for primary keys on the sys.seq$ table.
Amazon RDS restricts DBA users from issuing the GRANT command. Because SharePlex runs as the DBA user, SharePlex cannot replicate GRANT to or from an RDS database.
SharePlex provides expanded DDL support for Oracle objects that are not listed in the configuration file. SharePlex replicates the DDL statements for these objects, but does not maintain synchronization of the objects through DML replication. Expanded DDL replication is optional and is enabled with the following parameter setting:
SP_OCT_REPLICATE_ALL_DDL=1
Note: Expanded DDL replication supports not only tables and sequences but also a wide range of other objects such as procedures, functions, users, and views, which are not part of replication. Some of these objects may have underlying objects that are in replication. In those cases, Expanded DDL replication applies to the underlying objects in replication, as well as to the object that is not in replication.

Table Notes:
Amazon RDS restricts DBA users from issuing certain commands on an Amazon RDS database instance. Because SharePlex runs as the DBA user, SharePlex cannot replicate the following commands to or from an RDS database:
SharePlex provides limited DDL support for replication from Oracle to Open Target. The involved objects must be listed in the active configuration file explicitly or with a wildcard. There is no optional DDL support for replication from Oracle to Open Target.
The default Oracle to Open Target configuration is represented by the following parameter setting:
SP_OCT_REPLICATE_DDL=3
See "Table Notes" following this table for additional information.
| Supported object | Supported Operation |
|---|---|
| Table and IOT | Truncate1 |
| Alter table add column2 | |
| Alter table drop column |
Table Notes:
TRUNCATE TABLE is not supported from Oracle compressed objects to Open Target targets.
The default mappings of Oracle data types to their Open Target counterpart for replicated ALTER TABLE ADD COLUMN DDL is shown in Supported Operating Systems for Oracle . When SharePlex adds the column, it defines it with the default data type. This mapping applies to the entire configuration (not per table).
This is a list of commonly used Oracle features which SharePlex does not replicate and are not listed elsewhere in this document. Since both Oracle and SharePlex continually change and improve, this list of exclusions cannot be considered complete. Unless an item is stated here as being supported, assume that SharePlex does not replicate it.
| Object/operation/feature | Not supported |
|---|---|
| Oracle operations | Operations that do not appear in the redo logs. This includes any DML or DDL not in the redo logs, and also PL/SQL packages which do not write results to the redo logs, for example, dbms_shared_pool.keep and related packages. |
|
dbms_scheduler.create_job |
This object is not supported. |
| Flashback |
SharePlex does not support the Oracle Flashback Table feature. If the SP_REPLICATE_ALL_DDL parameter is enabled (value of 1), SharePlex may try to replicate the flashback DDL, which will return an error. To perform Flashback Table on a table that is in replication, use the following procedures
