CRR_CONTROL

CRR_CONTROL allows you to monitor the replication of recorded changes during an upgrade. Control of the replication (start of replication, stop of replication and change number of used processes) must be done from the CRR replication control in the SUM UI.

Sections

Transfer Control

• Total Number of Recorded Tables
  • Number of all tables registered for change recording.
• Tables Ready for Transfer
  • Number of tables ready for data transfer. That means that Data Base Triggers and Logging Tables have been created.
• Number of Used Dialog Processes
  • Number of dialog processes used to transfer the recorded changes to the shadow system. The number can be changed only if the transfer process is stopped.

Transfer Overview

• Status
  • Overall status of the transfer process.
• Ratio
  • Ratio of total recorded table rows in the original system and already processed or transferred rows in the shadow system.
• Total
  • Total number of recorded table rows in the original system.
• Processed
  • Total number of processed or transferred table rows in the shadow system.
• Not processed
  • Total number of not processed table rows.
• Growth/hour
  • Estimation on how many table rows will be recorded in one hour depending on the number of recorded table rows of the last 15 minutes.
• Transfer/hour

You can switch the view to show all tables. You can set a filter to check a specific table.

This section shows errors which occur during the transfer. You can restart the transfer process for individual tables after analyzing and fixing the errors.

• Table Name
  • Name of the affected tables.
• Status
  • Transfer status of the table.
• Info ID
  • The internal number of the table used by the CRR-Framework. It allows you to identify the corresponding logging table and transfer function modules.
• Group ID
