Hello nivedita,
This is the excerpt from the book: CICS PERFORMANCE GUIDE
RMITIME: Amount of elapsed time spent in the Resource Manager Interface (RMI).
| Quote: | In the explanation below: The term clock is distinguished from the term time stamp.
A clock is a 32-bit value, expressed in units of 16 microseconds, accumulated during one or more measurement periods. The 32-bit value is followed by 8 reserved bits, which are in turn followed by a 24-bit value indicating the number of such periods. Neither the 32-bit timer component of a clock nor its 24-bit period count are protected against wraparound. The timer capacity is about 18 hours, and the period count runs modulo 16 777 216.
The 8 reserved bits have the following significance:
Bits 0, 1, 2 and 3 Used for online control of the clock when it is running, and should always be zeros on output.
Bits 4 and 7 Not used.
Bits 5 and 6 Used to indicate, when set to 1, that the clock has suffered at least one out-of-phase start (bit 5) or stop (bit 6).
A time stamp is an 8-byte copy of the output of an STCK instruction.
Note: All times produced in the offline reports are in GMT (Greenwich Mean Time) not local time. Times produced by online reporting can be expressed in either GMT or local time. |
Hope this helps
Regards

nivedita,
RMI stands for Resource Manager Interface which is a program or a group of programs that you write to enable you to structure calls from your CICS system in such a way that they can access non-CICS resources, such as databases, that you would not normally be able to access. An RMI is written using the CICS task-related user exit interface. DBCTL, for example, is accessed by means of an RMI.
The variables you are talking of belong to the performace data in group DFHTASK
check this link for detailed explanation of the variables.

Hope this helps...
cheers
