continuously evaluating performance of the database while to determine when a predefined performance criterion is violated; and
in response to the predefined performance criterion being violated, sending information from the performance monitoring facility to the data protection manager to cause compliance with the predefined performance criterion,
wherein at least one of the foregoing operations is performed by a hardware processor.
2. The method according to claim 1 , wherein the backup operation includes a background copy process which starts with the backup operation, and wherein the performance monitoring facility is informed about the start of the backup operation and the start of the background copy process in the storage subsystem.
3. The method according to claim 2 , wherein a copy rate of the background copy process of the backup operation is reduced when the predefined performance criterion is violated.
4. The method according to claim 3 , further comprising:
determining when the predefined performance criterion is not violated;
checking if it is possible to increase the copy rate; and
increasing the copy rate when it is possible.
5. The method according to claim 2 , further comprising starting the background copy process asynchronously using the storage subsystem.
6. The method according to claim 2 , wherein the data protection manager informs the performance monitoring facility when the background copy process is started.
7. The method according to claim 2 , wherein the data protection manager informs the database when the backup operation is started to allow the database to enter a backup mode.
8. The method according to claim 7 , wherein when the background copy process ends, the data protection manager informs the database to exit the backup mode.
9. The method according to claim 2 , wherein the data protection manager informs the performance monitoring facility when the background copy process is finished.
10. The method according to claim 1 , wherein the data protection manager interacts with the storage subsystem to create relationships between source volumes and target volumes for the backup operation.
11. A computer program product comprising a computer readable medium having computer readable program code therein, the computer readable program code comprising:
computer readable program code configured to provide an interface between a performance monitoring facility of a database and a data protection manager, wherein the performance monitoring facility is adapted for measuring performance of the database regularly and the data protection manager is adapted for controlling a backup operation of the database on a storage subsystem;
computer readable program code configured to start the backup operation while informing the performance monitoring facility about the start of the backup operation and a start of a background copy process in the storage subsystem;
computer readable program code configured to continuously evaluate performance of the database to determine when a predefined performance criterion is violated; and
computer readable program code configured to send information from the performance monitoring facility to the data protection manager to cause compliance with the predefined performance criterion in response to the predefined performance criterion being violated.
12. A system, comprising:
a performance monitoring facility of a database configured to measure performance of the database regularly;
a data protection manager for controlling a backup operation of the database on a storage subsystem; and
a hardware processor and logic integrated with and/or executable by the hardware processor, the logic being configured to:
provide an interface between the performance monitoring facility of the database and the data protection manager;
cause the backup operation white informing the performance monitoring facility about the starting of the backup operation;
continuously evaluate performance of the database to determine when a predefined performance criterion is violated; and
send information from the performance monitoring facility to the data protection manager to cause compliance with the predefined performance criterion in response to the predefined performance criterion being violated.
13. The system according to claim 12 , wherein the backup operation includes a background copy process which starts with the backup operation.
14. The system according to claim 13 , wherein a copy rate of the background copy process of the backup operation is reduced when the predefined performance criterion is violated.
15. The system according to claim 14 wherein the logic is further configured to:
determine when the predefined performance criterion is not violated;
check if it is possible to increase the copy rate; and
increase the copy rate when it is possible.
16. The system according to claim 13 , wherein the performance monitoring facility is informed about the start of the backup operation and the start of the background copy process in the storage subsystem.
17. The system according to claim 13 , wherein the data protection manager informs the database when the backup operation is started to allow the database to enter a backup mode and interacts with the storage subsystem to create relationships between source volumes and target volumes for the backup operation.
18. The system according to claim 17 , wherein the data protection manager informs the performance monitoring facility when the background copy process is finished.
