Prevent TCLPROG File Checking

System performance is improved if TCLPROG file checking is not performed. At the

TCP level, set the CHECK-DIRECTORY attribute to OFF to prevent the system from

checking the TCLPROG file. To prevent the system from checking the TCLPROG file

at the TERM and PROGRAM level, you must remove the TCLPROG file.

Because partitioned code is easier to manage, you must weigh the cost of reduced

manageability when considering whether to improve system performance using this

method.

Improving Ready-Time-to-Busy-Time Ratio

The ready-time-to-busy-time ratio can have a significant effect on a transaction’s

elapsed time.

For example, if the TCP CPU time for a transaction is 300 ms and the ready-time-to-

busy-time ratio is 6 to 1, the elapsed time in the TCP for this transaction is 1.8

seconds. This applies to all processes in the transaction’s execution path.

A high ratio is usually an indication of an ever-busy CPU for that process, or of

inappropriate priority settings. Remember that raising the process’ priority is likely to

increase the ready-time-to-busy-time ratio for some other process or processes in that

CPU.

You can use these products to determine the ready-time-to-busy-time ratio:

•

Measure product

•

HP Tandem Performance Data Collector (TPDC)

•

FlowMap product

For information about setting process priority, see Section 2, Configuring Pathway/iTS

Objects.

Information to Include When Reporting

Problems

When requesting your service provider’s help in resolving a problem with the

Pathway/iTS product, you can greatly enhance the service provider’s ability to help you

by providing information about your Pathway environment. Information to be collected

for Pathway/iTS components is covered in this subsection. For a description of

information you need to collect for TS/MP objects and processes, see the TS/MP

System Management Manual.

TCP-Specific Problems

Collect this information if you detect a problem with a TCP.
