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 to work around this issue:

For OLTP, SharePlex supports the following operating systems only:
CentOS Linux 7.x and 8.x
SuSE SLES 12.x and 15.x
HP-UX 11.31 Itanium
SharePlex supports the Standard and Enterprise Editions of Oracle 12cR1, 12cR2, 18c, and 19c for replicating the OLTP compressed data.
SharePlex supports DML operations on tables and sequences, with some conditions. DML can be replicated from an Oracle source to an Oracle or an open 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.
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.
|
Notes: ALTER TABLE to ADD COLUMN and ALTER TABLE to DROP COLUMN are supported on Basic, Advanced Row (OLTP) Compression, and HCC compressed Oracle objects for replication to all Oracle and open targets. |
SharePlex does not support:
SharePlex provides limited DDL support for replication from Oracle to open targets. 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 cross platforms.
The default Oracle to open target configuration is represented by the following parameter setting:
SP_OCT_REPLICATE_DDL=3

SharePlex supports replication from Oracle to Snowflake, according to the details below.
SharePlex replicates remotely to Snowflake. Remote replication from the following operating systems is supported:
Red Hat Linux version 7.x, 8.x
Note: SharePlex Snowflake supports only the 64-bit version of the listed operating systems.
Snowflake 6.31 Enterprise, Community version
ODBC driver requirement: Snowflake 2.25.10
Note: If you cannot use ODBC 2.25.10, use the ODBC 2.24.2 version instead.
| Limitations:
The following ODBC driver related limitations are observed while replicating data from Oracle to Snowflake:

SharePlex supports the following data types for replication from Oracle to Snowflake:
| Oracle | Snowflake |
|---|---|
| CLOB | TEXT |
| NUMBER | INT, INTEGER, NUMBER |
| CHAR(n) | VARCHAR(n) |
| CLOB | VARCHAR(n) |
| NCHAR | CHAR(n) |
| VARCHAR2(n) | VARCHAR(n) |
| CLOB | VARCHAR(n) |
| NCLOB | TEXT |
| CLOB | VARCHAR(n) |
| LONG | TEXT |
| BLOB | BINARY, VARBINARY |
| RAW(n) | VARBINARY |
| LONGRAW | VARBINARY |
| BINARY_FLOAT | REAL |
| NUMBER | SMALLINT |
| NUMBER | BIGINT |
| NUMBER | NUMERIC, DECIMAL |
| DATE | DATE |
| BINARY_DOUBLE | DOUBLE PRECISION |
| TIMESTAMP | TIMESTAMP |
| TIMESTAMP_TZ | TIMESTAMP_TZ |
Note: It is anticipated that the Snowflake DB's default "HEX" format for binary type will be maintained for Oracle binary to Snowflake binary data type replication. Since source Oracle DB binary data is stored only in "HEX" format, Shareplex does not guarantee data integrity for any other format.
Char(n) data type - In Oracle, Char(n) is a fixed-size data type. If you insert char data with a length less than "n" into the "Char(n)" column, the remaining slots (n - length) are padded with space to occupy the complete "n" memory positions. Snowflake uses VARCHAR(n) for char storage since Snowflake lacks a comparable fixed-length character data type and only saves char data up to its length. Live replication will ensure that char column data is correctly copied. However, if users are manually inserting data into Snowflake for the equivalent of a Char(n) Oracle column, then the user will need to handle padding as well to occupy the full "n" length so that data will be in sync in both the source and target DB.
Binary & Text data types - Snowflake Binary & Text data types have size limitation of 8 MB, so Oracle’s advance Data type replication will be restricted to max 8 MB size limit of equivalent counterpart. Refer table below.
| Oracle Data type | Max Size | Snowflake Data type | Max Size |
|---|---|---|---|
| LONG | 2 GB | TEXT | 8 MB of unicode chars |
| CLOB | 4 GB | TEXT | 8 MB of unicode chars |
| LONGRAW | 2 GB | BINARY or VARBINARY | 8 MB |
| BLOB | 4 GB | BINARY or VARBINARY | 8 MB |
See Conditions of support for the additional conditions of support for the above-mentioned supported data types.

SharePlex PostgreSQL supports the following data types for replication from PostgreSQL Database as a Service to PostgreSQL:
SharePlex supports DML operations on tables. DML can be replicated from a PostgreSQL Database as a Service to a PostgreSQL target.
SharePlex supports the following DML operations on tables:
The target table must support the column types that are being replicated from the source PostgreSQL table.
Currently, SharePlex does not support DDL operations when replicating data from a PostgreSQL Database as a Service as source to a PostgreSQL target. It only supports tables as objects for data replication.
SharePlex supports replication from PostgreSQL Database as a Service to Snowflake, according to the details below.
The following operating systems are supported for capture from a PostgreSQL Database as a Service and replication to a Snowflake target database. SharePlex Snowflake supports only the 64-bit version of the listed operating systems.
SharePlex replicates remotely to Snowflake. Replication from the following operating systems is supported:
Red Hat Linux version 7.x and 8.x
Snowflake 6.31 Enterprise, Community version
ODBC driver requirement: Snowflake 2.25.10
Note: If you cannot use ODBC 2.25.10, use the ODBC 2.24.2 version instead.
| Limitations:
The following ODBC driver related limitations are observed while replicating data from Oracle to Snowflake:

SharePlex supports the following data types for replication from PostgreSQL Database as a Service to Snowflake:
| PostgreSQL | Snowflake |
|---|---|
| TEXT | TEXT |
| INT | INT,INTEGER,NUMBER |
| CHAR(1:2000) | VARCHAR(n) |
| CHAR(2001:) | VARCHAR(n) |
| CHAR(n) | CHAR(n) |
| VARCHAR(1:4000) | VARCHAR(n) |
| VARCHAR(4001:) | VARCHAR(n) |
| VARCHAR | VARCHAR(n) |
| REAL | REAL |
| SMALLINT | SMALLINT |
| BIGINT | BIGINT |

| TIMESTAMP | TIMESTAMP |
| TIMESTAMP_TZ | TIMESTAMP_TZ |
| BOOLEAN | BOOLEAN |
| TIME | TIME |
Char(n) data type - In PostgreSQL, Char(n) is a fixed-size data type. If you insert char data with a length less than "n" into the "Char(n)" column, the remaining slots (n - length) are padded with space to occupy the complete "n" memory positions. Snowflake uses VARCHAR(n) for char storage since Snowflake lacks a comparable fixed-length character data type and only saves char data up to its length. Live replication will ensure that char column data is correctly copied. However, if users are manually inserting data into Snowflake for the equivalent of a Char(n) PostgreSQL column, then the user will need to handle padding as well to occupy the full "n" length so that data will be in sync in both the source and target database.
Text data types - Snowflake Text data types have size limitation of 8 MB, so PostgreSQL’s TEXT data type replication will be restricted to max 8 MB size limit of equivalent counterpart. Refer table below.
| PostgreSQL Data type | Max Size | Snowflake Data type | Max Size |
|---|---|---|---|
| TEXT | unlimited | TEXT | 8 MB of unicode chars |
See Conditions of support for the additional conditions of support for the above-mentioned supported data types.
SharePlex supports DML operations on tables, with some conditions. DML can be replicated from an PostgreSQL Database as a Service to a Snowflake target.
SharePlex supports the following DML operations on tables when replicating data from an PostgreSQL Database as a Service to the Snowflake target:
