SymmetricDS
vs
Quest SharePlex
Real-time data sync without vendor lock-in
Quest SharePlex has strong Oracle and PostgreSQL credentials, but SymmetricDS provides native sync across 40+ database types. Flat pricing and offline capability eliminate vendor constraints.
Key difference
Database diversity drives the decision
SharePlex remains Oracle and PostgreSQL-centric despite adding some targets. SymmetricDS handles 40+ database types natively with full bidirectional sync between any combination.

- SymmetricDS
- Quest SharePlex
| Feature | SymmetricDS |
Quest SharePlex |
|---|---|---|
| Replication modes |  Four modes mixable per table — log-based CDC, trigger-based, time-based, data refresh. |
 Log-based CDC for Oracle and PostgreSQL with limited additional target support. |
| Bi-directional replication | Native bidirectional sync with conflict resolution across any database combination. |
Active-active bidirectional replication primarily for Oracle and PostgreSQL environments. |
| Deployment flexibility | Container-native deployment on-premise, cloud, edge, and air-gapped environments. |
Traditional enterprise deployment model with continuous connectivity requirements. |
| Open source | AGPL v3 Community Edition with commercial Standard and Enterprise options. |
 Proprietary Quest Software platform with custom enterprise licensing model. |
| Offline / edge support | Store-and-forward capability synchronizes when connectivity returns to edge locations. |
Requires continuous network connectivity for replication to function properly. |
| Pricing model | Predictable flat node-based pricing with transparent subscription model. |
Custom enterprise licensing with perpetual plus 22% annual maintenance fees. |
| True heterogeneous multi-database support | Native support for 40+ database types with full bidirectional capabilities. |
Oracle and PostgreSQL focus with limited heterogeneous target additions. |
| Proven scale at 10,000+ nodes in production | Validated enterprise scalability with customers running 10,000+ nodes in production. |
Quest's scalability claims lack public references at comparable deployment scales. |
| Open-source foundation with commercial support | Vendor-neutral open source foundation prevents platform lock-in while providing commercial support. |
Proprietary platform creates dependency on Quest Software for long-term viability. |
| Hands-on Jumpmind support model | Direct access to engineers who built the product for faster resolution. |
Tiered enterprise support system with potential delays in ticket escalation. |
| New AI Insights for automated performance… | Performance monitoring through traditional dashboards and alerting mechanisms. |
AI Insights provides automated performance optimization and diagnostic capabilities. |
| Expanded target support now includes SQL… | Comprehensive native support across all major database platforms from inception. |
Recent expansion to SQL Server, MySQL, MariaDB, and cloud storage platforms. |
| 24x7x365 Quest enterprise support backing | Jumpmind provides dedicated support with direct engineer access during business hours. |
Quest delivers 24x7x365 enterprise support with 95% customer satisfaction ratings. |
Where SymmetricDS replaces Quest SharePlex
Real deployments where database diversity, connectivity constraints, or cost predictability matter.
Multi-database environments
Sync between Oracle, MySQL, PostgreSQL, SQL Server in one topology. SharePlex requires separate tools for non-Oracle connections.
Edge and retail
Store databases sync to headquarters with offline support. SharePlex stops working when network connections drop.
Cost predictability
Flat node pricing scales linearly with growth. Quest's custom licensing creates budget uncertainty for expanding deployments.
A realistic migration path
Switch without disrupting production synchronization.
-
1
Audit current topology
Document SharePlex routing rules, transformation logic, and performance baselines to establish migration requirements.
-
2
Deploy SymmetricDS alongside
Install SymmetricDS on target systems and configure parallel replication streams without touching SharePlex.
-
3
Validate data consistency
Run Compare & Repair to verify SymmetricDS delivers identical results before switching production traffic.
-
4
Cut over and decommission
Redirect applications to SymmetricDS endpoints during maintenance window, then remove SharePlex infrastructure.
Most migrations complete in under two weeks with zero data loss.
