SharePlex uses the TDE primary Encryption Key to decrypt TDE-protected data that must be replicated. SharePlex uses the Oracle wallet password to access the TDE primary Encryption Key.
If the wallet opens successfully, Capture connects to the decryption module and processes the data. If the wallet does not open, Capture remains in the initialization state until either the wallet is opened or the process is stopped. The initialization state that is displayed in the show capture command is "Capture state: Waiting for open wallet."
Note: The SharePlex copy/append command does not support TDE. For full information on the Oracle features that SharePlex supports, see the SharePlex Release Notes.
To decrypt TDE-protected data from the redo log, the SharePlex Administrator must open Oracle Wallet using the wallet password. By default, only the Oracle Wallet owner-user has read and write permissions for this file. You can either start as the owner of the wallet, or you can grant read permission to the file to the dba group, because the SharePlex Administrator user is a member of that group.
To configure SharePlex to support TDE-protected data, two setup tools must be run:
To run sp_wallet and manually supply the password
On the source system, start SharePlex from the SharePlex product directory. You are prompted to run sp_wallet.
*** To enable TDE replication, run sp_wallet and provide the wallet password ***
Run sp_wallet.
./sp_wallet [-r port_number]
Important! On Windows, if you installed SharePlex on any port other than the default of 2100, use the -r option to specify the port number. For example, in the following command the port number is 9400:
./sp_wallet -r 9400
wallet password: walletpw
Wallet loaded into SharePlex
To run sp_wallet in auto-open mode
If you are using an auto-open wallet, you can configure SharePlex to open the TDE wallet automatically. This eliminates the need to run sp_wallet manually at SharePlex startup. The syntax is:
./sp_wallet --auto-open [-r port_number]
Important! Using the auto-open wallet feature has additional security considerations. See the Oracle documentation for more information. In addition, do not back up the SharePlex variable-data directory together with the Oracle wallet and the Oracle data files.
To cancel auto-open mode
./sp_wallet --no-auto-open [-r port_number]
To change the TDE primary encryption key
If you need to change the TDE primary Encryption Key while a SharePlex configuration is active, take the following steps to ensure that SharePlex continues to replicate the TDE-protected data after the changes.
Run the sp_wallet utility to provide SharePlex with the new TDE primary Encryption Key.
./sp_wallet [-r port_number]
Set up replication from Oracle to MySQL
Set up replication from Oracle to SQL Server
Set up replication from Oracle to PostgreSQL
Set up replication from Oracle to other Open Targets
This chapter contains instructions for configuring SharePlex to replicate from Oracle to a different type of target. This is known as heterogeneous replication.
These instructions highlight specific tasks that are pertinent to the flow of data between source and target. Refer to other topics in the SharePlex documentation as needed to complete the configuration, deploy any optional features that apply, and monitor and maintain the environment.
For additional information, see:
SharePlex can post replicated Oracle data to a MySQL or Aurora target database through an Open Database Connectivity (ODBC) interface.
These instructions contain setup instructions that are specific to this target. Install SharePlex on the source and target according to the appropriate directions in this manual before performing these setup steps.
For the versions, data types and operations that are supported when using SharePlex to replicate to this target, see the SharePlex Release Notes.
Important! If replicating to MySQL or Aurora on a PaaS cloud server (no access to the operating system), see the installation instructions in Installation and setup for cloud-hosted databases.
To support replication between a source of one database type and a target of another type, the letter case of the names of the source and target columns must be the same, for example the column names on both sides in lower case or both sides in upper case. If the case differs between the source and target column names, use the column mapping feature to map the column names in the configuration file.
See the SharePlex Administration Guide for more information about column mapping with SharePlex.
Set up SharePlex and the database on the Oracle source system as follows.
To replicate from an Oracle source to an Open Target target, you must make key information available to SharePlex.
Enable PK/UK supplemental logging in the Oracle source database. SharePlex must have the Oracle key information to build an appropriate key on the target.
Set the SP_OCT_USE_SUPP_KEYS parameter to a value of 1. This parameter directs SharePlex to use the columns set by Oracle's supplemental logging as the key columns when a row is updated or deleted. When both supplemental logging and this parameter are set, it ensures that SharePlex can always build a key and that the SharePlex key will match the Oracle key.
See the SharePlex Reference Guide for more information about this parameter.
On the source, create a SharePlex configuration file that specifies capture and routing information.

If target owner or table name is defined in the database as anything other than UPPERCASE, be certain to:
Note: This is a basic one-source, one-target configuration using no additional SharePlex configuration features. See "Configure SharePlex to replicate data" in the SharePlex Administration Guide for important information about creating a configuration file and for additional setup instructions for more complex replication scenarios.
The following configuration file replicates table HR.Emp from Oracle instance ora112 to target table region1.emp in database mydb on target system sysprod. The source table is case-sensitive.
Datasource:o.ora112
HR."Emp" region1.emp sysprod@r.mydb
