This is only for the process NEWOLUF2 after this i'll change to other process and the content is in a file from the file we have to read the data and perform the task the exact scenario is as follows..

Please write a C program that give us sufficient performance statistics on the WSodrms server.
The program name should be WSodrmsStatistics.c.


The program should do the folloiwing:

1) It should have -s -e options to read start and end of timer interval we want to measure.
2) Scan throgh the log file and pick all NEWOLUF2 tranactions from the logfile within the user defined time interval
3) Save the TimeStamp and ElapseTime in a structure, which you add to a list with AddToTailAL():

typdef struct {
char *strTransactionName[LEN_TRANS_NAME + 1];
int intTimeStamp;
int intElapseTime;
}

3) Calculate the average value over the elements in the list.
4) Print with Logging functions (LOGTYPE_NOPREFIX) the following information:
Transaction name = <strTransactionName> TimeInterval <HHMISS - HHMISS> Average Elapse Time: <XX.XX>
show the result in Seconds with 2 decimals (SS.SS)

ualarm

ualarm(2)							System Calls Manual							 ualarm(2)

NAME

       ualarm - set the interval timer

SYNOPSIS

DESCRIPTION

       The function causes the signal to be generated for the calling process after the number of real-time microseconds specified by the useconds
       argument has elapsed. When the interval argument is non-zero, repeated timeout notification occurs with a period in microseconds  specified
       by the interval argument. If the notification signal, is not caught or ignored, the calling process is terminated.

       Implementations	may place limitations on the granularity of timer values. For each interval timer, if the requested timer value requires a
       finer granularity than the implementation supports, the actual timer value will be rounded up to the next supported value.

       Interactions between and either or are unspecified.

RETURN VALUE

       The function returns the number of microseconds remaining from the previous call. If no timeouts are pending or if has not previously  been
       called, returns 0.

ERRORS

       No errors are defined.

APPLICATION USAGE

       The function is a simplified interface to and uses the interval timer.

SEE ALSO

       alarm(2), getitimer(2), sleep(3C), <unistd.h>.

CHANGE HISTORY

       First released in Issue 4, Version 2.
