Data and process flow

The Image Copy function of IMS HP Image Copy reads data from the IMS database and creates image copies. The function supports many features that facilitate creating image copies and monitoring database health.

For example, while IMS HP Image Copy creates image copies, it can start HASH Check to check the pointers in the database. It can also call the Integrated DB Sensor function to collect sensor data from the database and store it in the repository of IMS Tools Knowledge Base. IMS HP Image Copy can also request to stop and restart or quiesce and release the quiesce state of the database through IMS Tools Online System Interface.

The following figure illustrates the data flow of the Image Copy function in a configuration where these functions and the interface are used.
