SharePlex provides high-speed replication from Oracle database to different target databases and messaging containers on major Unix, Linux and Windows operating systems— both on-premises and in the cloud. SharePlex supports a wide variety of configurations to meet different and complex data availability needs.
SharePlex supports reliable Oracle high availability configurations where replication maintains a duplicate database in a different location that is ready for fast, seamless failover and failback in planned or unplanned mode.
You can also use SharePlex to replicate data from Oracle source to maintain a change history database in an Oracle target. Rather than updating or deleting target rows based on the source change, SharePlex inserts a new row on the target for every source change. The result is an archive that reflects the chronological history of every change made to the source database.
SharePlex also includes, at no extra charge, the compare and repair tools that you need to verify the accuracy of a target maintained by replication. These tools not only detect hidden out-of-sync conditions, but they also repair the target to restore parity of your source and target data.
SharePlex value and versatility continues to grow with the requirements and requests of our customers. Although SharePlex is a reliable, relatively low-maintenance solution, our top-rated support team is ready around the clock to help with any trouble you may have. To get you started with your deployment, our professional services team is highly experienced and readily available.

This is a minor release and includes new features and enhanced functionality.
Database Support. This release of SharePlex includes support for the following database versions:
NOTE: 9.4.0 is a Linux only release. To properly replicate from SharePlex 9.4.0 capture (source) to a non-9.4.0 target, set the SP_SYS_TARGET_COMPATIBLITY. See Interoperability between versions for how to use and set this parameter.
NOTE: OLTP compression is not supported by SharePlex for replication of objects using DML operations in Oracle 18c and 19c. This limitation applies to objects in the source database.
SharePlex has put bug fixes into a cumulative update rollup (denoted by third digit in the version number)—starting with the 9.2.3 release. Customers that require bug fixes which are already available in a patch update rollup will be required to apply that patch release to get the bug fix.
The following is a list of issues addressed and enhancements implemented in this release of SharePlex.

This chapter contains the basic system requirements for SharePlex. See also:
System Requirements for Oracle Capture
Before installing SharePlex, ensure that your system meets the minimum hardware and software requirements.
Per process memory of greater than or equal to 256 MB is required. Depending on how you configure SharePlex, there can be one or more of the following processes on a system:
Capture
Read
Export
Import
Post
For TLS connections, SharePlex supports TLS 1.2 (or later) only.
SharePlex supports IPv4 and IPv6 internet protocols. The following table shows the operating systems for which SharePlex was tested with IPv6.
Note: If the SP_SYS_HOST_NAME environment variable is set to an IPV6 address on the source system, SharePlex on the target system must be version 9.0 or later.

Refer to the following guidelines if the system where you are installing SharePlex is in a configuration where one or more other systems will continue to use an older version of SharePlex. An example is when installing or upgrading SharePlex on a target, but the source will continue to use SharePlex 8.6.x.
Versions with full interoperability
The following SharePlex versions are fully interoperable, including the Compare/Repair feature:
8.6.x
9.0.x
9.1.x
9.2.x
9.4.x
To support replication from a higher to a lower version, set the SP_SYS_TARGET_COMPATIBILITY parameter on the source system to the lower SharePlex version. If Capture is running, restart it.
Important: Downgrading from a higher to a lower version of SharePlex is not supported.
Notes:
If you upgrade the target to the current release at a future time, issue a reset for SP_OCT_TARGET_COMPATIBILITY on the source system to remove it from the SharePlex environment. Going forward, SharePlex will use the setting of the new SP_SYS_TARGET_COMPATIBILITY parameter, which defaults to the current version.
To reset SP_OCT_TARGET_COMPATIBILITY
Stop Capture.
sp_ctrl> stop capture
In sp_ctrl on the source system, issue the following command:
sp_ctrl>reset param SP_OCT_TARGET_COMPATIBILITY
Restart Capture.
sp_ctrl>start capture
