Locating isolation points in an application under multi-tenant environment

An apparatus including a memory storing executable instructions for locating isolation points in an application under multi-tenant environment, comprising:

• a scanning module configured to:
• scan the application, by using scanning rules, to obtain potential isolation points and relationships between the potential isolation points, and
• specify at least one shared point among the potential isolation points;
• a specifying module configured to specify at least one isolation point among the potential isolation points;
• an isolation point screening module configured to screen isolation points from the potential isolation points by using relationships between the specified at least one isolation point and the remaining potential isolation points;
• a shared point filtering module configured to filter out a shared point among the potential isolation points by using relationships between the specified at least one shared point and the remaining potential isolation points;
• and
• a conflict reporting module configured to detect whether the shared point exists among the screened isolation points,
• wherein at least one of the potential isolation points is of a static variable type, wherein all variable statements of the at least one of the potential isolation points are found through static analysis.
