For over two decades, SharePlex has provided high speed database replication for mission critical database environments.
SharePlex supports a wide variety of configurations to meet different and complex data availability needs. A primary class of use cases revolves around database scaling and availability.
SharePlex supports reliable Oracle and PostgreSQL high-availability and disaster recovery configurations where replication maintains a duplicate database in a different location that is ready for fast, seamless fail-over and failback in planned or unplanned mode.
SharePlex also supports bi-directional, active/active configurations with conflict resolution for PostgreSQL to PostgreSQL and Oracle to Oracle to support horizontal scaling and strategic placement of databases near regional users.
SharePlex can support cross platform (Oracle ← → PostgreSQL) bi-directional, active-active replication with conflict resolution to de-risk Oracle to PostgreSQL migrations in complex Oracle environments.
SharePlex can improve scaling by offloading Oracle or PostgreSQL reporting workloads.
Another class of use cases involves (generally) cross-platform data movement to support application integration, database interoperability and data lake population. Examples include:
PostgreSQL and/or Oracle replication to Snowflake to support data warehouse/data lake pipelines
PostgreSQL and/or Oracle replication to Kafka for real-time streaming analytic applications
PostgreSQL to Oracle (or) Oracle to PostgreSQL replication to provide interoperability between systems to support database refactoring or migration from Oracle to PostgreSQL.
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's value and versatility continue 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.

The following is a list of issues addressed in this release of SharePlex.
| Issue ID | Known Issues | Source and Target | Component/ Feature |
|---|---|---|---|
| SPO-24959 |
During Oracle-to-Kafka replication, when the JSON DDL option is set to "no" (json ddl=no), SharePlex is encountering the following two issues:
|
Oracle-to-Kafka | JSON DDL |
| SPO-24942 | The Oracle Poster process is displaying the code has triggered message in the OPO logs in all SharePlex environments where version 11.4 is installed. | Oracle to Oracle | Poster |
| SPO-24920 | The Poster process is displaying the invalid byte sequence for encoding 'UTF8': 0xc3 0x41 error when users insert multiple rows of Western European character data into a table. | Oracle to PostgreSQL | Poster |
| SPO-24917 | If the table in replication has an IS JSON constraint, the event log displays the warning Command server: JSON column not supported during activation. | Oracle to Oracle | JSON column |
| SPO-24908 | The SQL Server Poster process stopped with a core dump while replicating data from Oracle to SQL Server due to an out-of-sync issue. | Oracle to SQL Server | Poster |
| SPO-24896 | While replicating data from one source to three targets, some tables are missing on two of the targets due to name mangling during the Reader process. | Multiple source and targets | Reader |
| SPO-24890 | Data frequently goes out of sync during the execution of the UPDATE statement while replicating data from Oracle to PostgreSQL. This occurs when the WHERE condition does not include the PK column values, and it retains the pre-image of the changed columns along with some random columns. | Oracle to PostgreSQL | UPDATE statement |
| SPO-24885 | SharePlex is unable to replicate NULL or empty string from PostgreSQL to PostgreSQL or EDB to EDB. | PostgreSQL to PostgreSQL, EDB to EDB | Empty string |
| SPO-24884 | Users are unable to set a SharePlex PostgreSQL Capture parameter to ignore transactions originating from a specific SharePlex port. | PostgreSQL to PostgreSQL | Capture |
| SPO-24879 | SharePlex Poster displays the 'TABLE DOESN’T EXIST' error when users do not grant the necessary privileges to existing tables during Oracle to Snowflake replication. | Oracle to Snowflake | Poster |
| SPO-24878 | The SharePlex Capture process encounters a core dump issue when replicating a table from Oracle to PostgreSQL where the last column has been dropped. However, this issue does not occur if any other column is dropped or if a new column is added after dropping the last column. | Oracle to PostgreSQL | Poster |
| SPO-24876 | The SharePlex Poster process stops with an error when replicating data from Oracle to PostgreSQL, if the table name, column name, or both exceed 30 characters. | Oracle to PostgreSQL | Poster |
| SPO-24872 | The PostgreSQL Repair process displays the error 'function concat() does not exist' when replicating a table with more than 34 columns from EDB to EDB. | EDB to EDB | PostgreSQL Repair |
| SPO-24862 | When replicating data from an on-premise Oracle source to an RDS PostgreSQL target, with SharePlex installed on EC2, the replication speed is slower than expected. | Oracle to RDS PostgreSQL | |
| SPO-24851 | During Oracle-to-Oracle replication on SharePlex version 11.3, after executing DML operations, the compare command returns a negative garbage value. Additionally, the repair status shows incorrect "Total Rows" information during the initial phase of execution. | Oracle-to-Oracle | Repair |
| SPO-24850 | Initial queries executed by SharePlex's open Poster to fetch metadata from the PostgreSQL database and manage the shareplex_open_trans table are entering in an idle_in_transaction state due to missing commits. | Oracle to AWS RDS PostgreSQL | Poster |
| SPO-24845 | The Poster process does not exit even if the execution time elapsed exceeds the time set through the SP_OPO_MAX_OEXN_TIME parameter. | Oracle to Oracle | Poster |
| SPO-24842 | Users are unable to replicate LOB column data to the target using a PL/SQL block when the data length exceeds 4000 characters. | Oracle to Oracle | LOB column |
| SPO-24812 | The SharePlex Capture process displays the '“Log parser error 12” with ORA-22287' error during while executing the remote capture operations in Oracle-to-Oracle replication. | Oracle to Oracle | Capture |
| SPO-24747 | SharePlex is unable to replicate XML data from Oracle to Oracle due to a duplicate tag in the code. | Oracle to Oracle | XML data |
