Redgate Monitor Adds Support for Oracle Multitenant

With the introduction of Oracle multitenant architecture in Oracle 12c, many teams began consolidating databases into a single Container database (CDB). This helped them to optimize resource usage and simplify patching.

However, while Oracle multitenant simplifies management, it can make monitoring harder. With multiple pluggable databases (PDBs) sharing the same instance, a slowdown in one can spill over into the others, and traditional instance-level (CDB-level) metrics won’t show you where the problem lies.

Full multitenant visibility with Redgate Monitor

With Oracle multitenant support in Redgate Monitor, you gain full visibility into activity and performance metrics at both the Container Database (CDB) level and for each individual Pluggable Database (PDB), ensuring no blind spots.

You can:

• Track resource usage per PDB – see how each PDB is consumes shared resources like CPU, memory, and IO, which is crucial for capacity planning and chargeback models
• Get metrics and alerts at the right level – if one PDB misbehaves, you’ll know immediately without digging through generic, instance-level metrics.
• Visualize performance trends across PDBs – our enhanced dashboards let you compare trends across PDBs, spot anomalies, and drill down into granular performance data
• Audit each PDB separately – track logins, privileges and activity at the PDB level, so you can prove each database is isolated and meets security and compliance standards.

No Configuration Headaches

To enable multitenant monitoring, just connect your Oracle CDB instance. Redgate Monitor will automatically detect and add each PDB, pulling in metrics, performance data, and health indicators.

No manual intervention. No complex setup.

Built for Enterprise-Scale Oracle Environments

Whether you’re managing a few pluggable databases or dozens, spread across multiple data centers, Redgate Monitor scales with your infrastructure, helping DBAs stay in control as estates grow and architectures evolve.
