FIX: Transaction Integrator transactions that communicate over TCP/IP may not time-out in the time-out period that is configured in the TI Remote Environment in Host Integration Server (891564)


The information in this article applies to:

  • Microsoft Host Integration Server 2004
  • Microsoft Host Integration Server 2000
Note The behavior that this article describes applies to Transaction Integrator (TI) in Microsoft Host Integration Server 2004 and to COM Transaction Integrator for CICS and IMS (COMTI) in Microsoft Host Integration Server 2000. Transaction Integrator (TI) it used throughout the article to indicate both TI and COMTI except where an explicit difference between the two versions exists.

SYMPTOMS

Transaction Integrator transactions that communicate over TCP/IP may not time-out in the time-out period that is configured in the TI Remote Environment (RE). A TI transaction may not time-out unless the time that is required for the host application to respond is more than double the time-out value that is configured in the RE. Therefore, TI transactions may not time out as quickly as you want.

For example, if you have specified a time-out value of 4 seconds, a transaction may not time out unless the host application does not respond for longer than 9.5 seconds.

Note To configure the TI time-out in Host Integration Server 2004, enter a value in the Receive box under the Time out in seconds option in the RE properties.

To configure the COMTI time-out in Host Integration Server 2000, enable the Timeout if no response within value seconds option.

When a TI transaction is eventually timed out, a message that is similar to the following is logged in the event log:
Event Type: Error
Event ID: 102
Source: COMTI
Description:
(102) COM Transaction Integrator reported the following exception to the client:
Component: COMTI component
Method: COMTI Method

Exception description:
(1434) The time out period for the method elapsed and no reply was received. Condition code = 00000000. If 0, timeout was normal. If not 0, it represents an error (GetLastError) encountered while waiting.

CAUSE

TI calls the recv function by using the MSG_PEEK flag to gather response time values. TI uses these values to monitor performance. As soon as the first recv function call is completed, TI issues another recv function without using the MSG_PEEK flag. This call enables TI to receive the actual data that the host application is returning.

If the first recv function call fails because the host application did not respond before the configured time-out expires, TI does not report a time-out exception (error 1434). However, if the second recv function call fails because the configured time-out has expired, TI returns the time-out exception. This behavior causes an effective TI time-out that is more than double the configured time-out.

RESOLUTION

After you apply the following hotfix, TI will return the time-out exception if the first recv function call that uses the MSG_PEEK flag fails because the configured time-out has expired. This behavior enables the TI transaction to detect time-out conditions in the time that you have specified in the RE properties.
