This document describes the accounting records for Broker that can be used for several purposes, including:

• application chargeback
  for apportioning EntireX resource consumption on the conversation and/or the application level;

• performance measurement
  for analyzing application throughput (bytes, messages, etc.) to determine overall performance;

• trend analysis
  for using data to determine periods of heavy and/or light resource and/or application usage.

This document covers the following topics:

• EntireX Accounting Data Fields

• Using Accounting under z/OS

• Example Uses of Accounting Data

Using Accounting under z/OS

The ACCOUNTING attribute indicates if accounting records will be generated. Accounting records are written upon successful completion of a conversation. A conversation ending in an application error (such as a timeout) is considered to be a successful conversation.

Attribute File

ACCOUNTING={NO|128-255}

Set this parameter to "NO" (i.e., do not create accounting records) or to a number between 128 and 255, which specifies the SMF record type to use when writing the accounting records. In order to avoid conflicts with other applications that also produce SMF records, check with your z/OS systems programmer for an appropriate number. In addition, check with your z/OS systems programmer to ensure that the selected SMF record number is set up to be written.

Default value: NO

Retrieving Accounting Records

The standard IBM IFASMFDP utility program may be used to selectively offload Broker SMF records. Analysis and report routines - either user-written or those available from IBM or various software vendors - may subsequently be used to process the offloaded records.

Accounting Record Layouts

EntireX provides three mappings for its accounting records in the following members, all located in the EXX105.SRCE data set:

• EXXCACT - A C language include file that maps the accounting record;

• EXXACTR - An Assembler language MACRO that will generate a DSECT of the accounting record;

• EXXSACT - An SAS DATA step that will read in a file with the appropriate field names.

Notes

• Since there is no server for Broker Command and Information Services, no server data is generated in the SMF records for Command and Information Services conversations.

• The unit for CPUTIME is expressed in microseconds.

Example Uses of Accounting Data

• Chargeback

• Trend Analysis

• Tuning for Application Performance

Chargeback

Customers can use the EntireX accounting data to perform chargeback calculations for resource utilization in a data center. Suppose EntireX Broker is being used to dispatch messages for three business departments: Accounts Receivable, Accounts Payable, and Inventory. At the end of each month, the customer needs to determine how much of the operation and maintenance cost of EntireX Broker should be assigned to these departments. For a typical month, assume the following is true:

Department	Amount of Data	Percentage	Messages Sent	Percentage	Average Percentage
Accts Payable	50 MB	25	4000	20	22.5
Accts Receivable	40 MB	20	6000	30	25
Inventory	110 MB	55	10000	50	52.5

The use of Broker resources here is based upon both the amount of traffic sent to the Broker (bytes) as well as how often the Broker is called (messages). The average of the two percentages is used to internally bill the departments, so 52.5% of the cost of running EntireX Broker would be paid by the Inventory Department, 25% by the Accounts Receivable Department, and 22.5% by the Accounts Payable Department.

Trend Analysis

The Accounting Data can also be used for trend analysis. Suppose a customer has several point-of-sale systems in several stores throughout the United States that are tied into the corporate inventory database with EntireX. The stubs would be running at the stores, and the sales data would be transmitted to the Broker, which would hand it off to the appropriate departments in inventory. If these departments wish to ascertain when the stores are busiest, they can use the accounting data to monitor store transactions. Assume all of the stores are open every day from 9 AM to 10 PM.

Local Time	Average: Weekday Transactions per Store	Maximum Weekday Transactions in any Store	Average Weekend Transactions per Store	Maximum Weekend Transactions in any Store
9 AM	7.3	27	28.2	83
10 AM	11.2	31	29.3	102
11 AM	14.6	48	37.9	113
12 noon	56.2	106	34.8	98
1 PM	25.6	65	34.2	95
2 PM	17.2	52	38.5	102
3 PM	12.1	23	42.7	99
4 PM	18.3	34	43.2	88
5 PM	26.2	47	45.2	93
6 PM	38.2	87	40.6	105
7 PM	29.6	83	39.2	110
8 PM	18.6	78	28.6	85
9 PM	11.2	55	17.5	62

The owner of the stores can examine the data and make decisions based upon the data here. For example, on weekdays, he or she can see that there is little business until lunchtime, when the number of transactions increase. It then decreases during lunch hour; then there is another increase from 5 PM to 8 PM, after people leave work. Based on this data, the owner might investigate changing the store hours on weekdays to 10 AM to 9 PM. On the weekend the trends are different, and the store hours could be adjusted as well, although there is a more regular customer flow each hour on the weekends.

Tuning for Application Performance

Assume that a customer has two applications that perform basic request/response messaging for similar sized messages. The applications consist of many Windows PC clients and Natural RPC Servers on UNIX. An analysis of the accounting data shows the following:

Application Type	Class	Server	Service	Average Server Messages Received per Conversation	Average Client Messages Received per Conversation
Application 1:	CLASS1	SERVER1	SERVICE1	10.30	10.29
Application 2:	CLASS2	SERVER2	SERVICE2	10.30	8.98

A further analysis of the accounting data reveals that there are a lot of non-zero response codes in the records pertaining to Application 2, and that a lot of these non-zero responses indicate timeouts. With that information, the customer can address the problem by modifying the server code, or by adjusting the timeout parameters for SERVER2 so that it can have more time to get a response from the Service.
