25.4.01

Large and very large tablespace classification for Pluggable Database Tablespaces

The large and very large tablespace classification is supported for Pluggable Database (PDB) tablespaces. With this feature, you can maintain a consistent, size‑based categorization for pluggable tablespaces. You can quickly identify and focus on the tablespaces that pose the highest capacity risk, improving triage speed and reducing operational overhead.
Use the following pconfig variables to categorize PDB tablespaces by size:

• Environment-level:
  • /KOE/Oracle/<EnvType>/<EnvName>/PluggableLargeTablespaceSize
  • /KOE/Oracle/<EnvType>/<EnvName>/PluggableVeryLargeTablespaceSize
• Global-level:
  • /KOE/Oracle/PluggableVeryLargeTablespaceSize
  • /KOE/Oracle/PluggableLargeTablespaceSize

With these variables, you can define the size limits in MB to classify PDB tablespaces as large or very large. After you configure these values, the PATROL Agent uses the thresholds to determine the appropriate classification for each PDB tablespace.
This capability is supported across the following Oracle monitoring environments:

• Oracle Standalone Database
• Oracle Data Guard Database
• Oracle Real Application Cluster or Real Application Cluster One Node Database

For more information, see Configure large and very large tablespace categorization.

The following new application classes are added for pluggable database tablespaces:

• Oracle Pluggable Large Tablespace (KOE_INST_PLUGGABLE_LARGE_TABLESPACE)
• Oracle Pluggable Very Large Tablespace (KOE_INST_PLUGGABLE_VERY_LARGE_TABLESPACE)

Configure Global Custom Query to improve operational efficiency

Configure Global Custom Query configuration in BMC Helix PATROL for Oracle Enterprise Database to centrally manage SQL-based monitoring across environments. By configuring a custom SQL query once, you can apply it across multiple Oracle database instances and environments, eliminating the need for repetitive configurations. This capability improves operational efficiency and enhances monitoring capabilities. 

For more information, see Configuring Global Custom Query for monitoring Oracle Enterprise Database.

Resolve issues faster by using the new parameter in the Sessions

application class

Use the User IO active sessions parameter to gain a deeper understanding of your Oracle database sessions' activities, including user input/output (i/o) active sessions, active and inactive sessions, and lock conflicts. This parameter supports performance diagnostics and proactive issue resolution.

For more information, see Sessions.
