About Rotating PDC Log Files

During log file rotation, PDC cloud native writes to a log file until it reaches a maximum size. It then closes the log file and starts writing to a new log file. Rotation prevents your log files from growing too large, making them slow to open and search.

You can set these log file rotation properties for PDC applications:

  • Log level: Sets the logging level, which can be SEVERE, WARNING, INFO, CONFIG, FINE, FINER, or FINEST.

  • Log limit: Sets the log files' maximum file size in bytes. After the log file meets the maximum, PDC closes the log file and creates a new log file.

  • Log file count: Specifies the maximum number of log files to retain for the application.

  • Persist log setting: Specifies whether to persist log files in the database after they are closed. Possible values are:

    • enabled or all: Persists all log files.

    • disabled: Does not persist log files.

    • failed: Persists failed log files only.

    Note:

    Only Real-Time Rating Engine (RRE) and Batch Rating Engine (BRE) transaction log files and ImportExportPricing log files can be persisted.

Table 21-1 lists the PDC application's default log file rotation settings.

The following sections show how to configure log file rotation for PDC cloud native applications.

Configuring Pricing Server Log File Rotation

This shows sample override-values.yaml keys for oc-cn-op-job-helm-chart. It configures log file rotation for the Pricing Server logs and tracer logs: 

ocpdc:
   configEnv:
      pdcAppLogLevel: WARNING
      pdcAppLogFileSize: 500000
      pdcAppLogFileCount: 50

Configuring ImportExportPricing Log File Rotation

This shows sample override-values.yaml keys for oc-cn-helm-chart. It configures log file rotation for the ImportExportPricing utility: 

ocpdc:
   configEnv:
      importExport:
         logLevel: SEVERE
         logSize: 50000
         logCount: 100
         persistIELogs: true

Configuring SyncPDC Log File Rotation

This shows sample override-values.yaml keys for oc-cn-helm-chart. It configures log file rotation for the SyncPDC utility: 

ocpdc:
   configEnv:
      syncPDC:
         logLevel: INFO
         logFileSize: 50000
         logFileCount: 100

Configuring RRE/BRE Log File Rotation

This shows sample override-values.yaml keys for oc-cn-helm-chart. It configures log file rotation for the RRE/BRE transformation master log and transaction logs: 

ocpdc:
   configEnv:
      transformation:
         logLevel: INFO
         logFileSize: 50000
         logFileCount: 100
         persistTransactionLogs: failed
