Hello Ranchers:

I am trying to run concurrency test on delete method. My pseudo code is



Consider this scenario:
100 = lockRecord(5)
deleteRecord(5, 100)
unlock(5, 100)

lockRecord(5) will throw RNFE
unlock(5, 0) will throw Security Exception when in theory I was expecting RNFE.
unlock() method had only SecurityException and didnt have RecordNotFoundException in the signature in my
assignment. How is everyone handling this?

Thanks,

Harish
Start Reading Monkhouse book. It has all the background needed. Do more research on a topic by topic basis as you read the book.

Never give any of your original documents to anybody. You can give them photocopies if they want. I have heard about people taking passports also. This is against law.

Contract of 18 months without sponsoring h1-b and giving 60 percent later on doesnt sound good to me at all.

AVOID that company.

Hi all:

Here is the spec I got



I have checked for RNFE if the record is not existing in FileManager hashmap or already marked as deleted. I have thrown security exception, when cookie is not matching with the existing cookie in the hashmap or if recno doesnt exist in the lockManager hashmap itself(question: am I OK here).

I have seen in many posts they are recommending
lockRecord() - can somebody explain me why we should use lockRecord() here. I am thinking we are deleting an already locked record. If we use lockRecord(), dont we get a new cookie value here.
deleteRecord() - fine
unlock() - fine

Here is what I have coded in my Data.class


thanks,

Harish

question: Why should we lock() first, if the record is already
