In Java EE applications, what is the purpose of the `@Resource` annotation?

A Windows 2000 Server computer named server2 runs numerous 32bit applications and two 16bit applications. Users start the 16bit applications by running APP1.EXE for one application and APP2.EXE for another application. The 16bit applications are configured to run in the separate memory space. You want to create a performance base like chart in the system monitor for all the applications on server2. You add all of 32bit applications and now you want to add two 16bit applications. What should you do?

A

Add the APP1 and APP2 instances to the processor time counter for the process object

B

Add the NTVDM, APP1 and APP2 instances for the processor time counter for the process object

C

Add only the NTVDM instance for the percent processor time counter for the process object

D

Add the NTVDM 1 and NTVDM #2 instances for processor time counter for the process object

E

None of above

Consider the following policies for preventing deadlock in a system with mutually exclusive resources. I. Processes should acquire all their resources at the beginning of execution. If any resource is not available, all resources acquired so far are released II. The resources are numbered uniquely, and processes are allowed to request for resources only in increasing resource numbers III. The resources are numbered uniquely, and processes are allowed to request for resources only in decreasing resource numbers IV. The resources are numbered uniquely. A process is allowed to request only for a resource with resource number larger than its currently held resources Which of the above policies can be used for preventing deadlock?

A

Any one of I and III but not II or IV

B

Any one of I, III, and IV but not II

C

Any one of II and III but not I or IV

D

Any one of I, II, III and IV

Consider a computer system with multiple shared resource types, with one instance per resource type. Each instance can be owned by only one process at a time. Owning and freeing of resources are done by holding a global lock (L). The following scheme is used to own a resource instance: function OWNRESOURCES(Resource R) Acquire lock L / / a global lock if R is available then Acquire R Release lock L else if R is owned by another process P then Terminate P, after releasing all resources owned by P Acquire R Restart P Release lock L end if end if end function Which of the following choice(s) about the above scheme is/are correct?

A

The scheme may lead to starvation.

B

The scheme may lead to live-lock.

C

The scheme ensures that deadlocks will not occur.

D

The scheme violates the mutual exclusion property.
