1. A method, comprising:
- monitoring at least one operating condition associated with a database;
accessing a prestored threshold value associated with the at least one operating condition;
comparing a value representative of the monitored operating condition with the prestored threshold value; and
adjusting a number of copies of at least a portion of the database based on the comparison.

Abstract
A method and apparatus is provided for adjusting a number of database replicas of a database based on a defined threshold value. The method comprises monitoring at least one operating condition associated with a database and accessing a prestored threshold value. The method further comprises comparing a value representative of the monitored operating condition with the prestored threshold value and adjusting a number of copies of at least a portion of the database based on the comparison.

9. An article comprising one or more machine-readable storage media containing instructions that when executed enable a processor to:
-
determine at least one operating condition associated with a database;
access a prestored threshold value;
compare a value representative of the determined operating condition with the prestored threshold value; and
adjust a number of database replicas based on the comparison. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. An apparatus, comprising:
-
a storage unit having stored therein a database; and
a control unit communicatively coupled to the storage unit, the control unit adapted to;
determine at least one operating condition associated with the database;
access a prestored threshold value;
compare a value representative of the determined operating condition with the prestored threshold value; and
adjust a number replicas of the database based on the comparison. - View Dependent Claims (17, 18, 19, 20, 21, 22)

23. A system, comprising:
-
a first server; and
a second server communicatively coupled to the first server, the second server adapted to;
determine at least one operating condition associated with a database;
access a prestored threshold value;
compare a value representative of the determined operating condition with the prestored threshold value; and
cause a replica of the database to be created on the first server based on the comparison. - View Dependent Claims (24, 25)

26. A method, comprising:
-
monitoring at least one of a user load level and network traffic level associated with accessing of a database;
accessing a preselected threshold value;
comparing at least one of the user load level and network traffic level with the preselected threshold value; and
automatically adjusting a number of copies of at least a portion of the database based on the comparison. - View Dependent Claims (27, 28, 29)
