Introduction

FLEXLM_TIMEOUT is a Windows-only environment variable which sets the timeout value that a Flex-enabled application uses when attempting to connect to a license server.

Summary

The substitute for FLEXLM_TIMEOUT would be to use LM_A_CONN_TIMEOUT client side attribute which can be used to extend the default FLEXLM_TIMEOUT value for connection to the server.

As of FlexNet Publisher 11.17.2

At the time of writing this Knowledge Base article, the latest available GA toolkit was FlexNet Publisher 11.17.2.

This environment variable helps to set the timeout values.

• The value of the environment variable is in microseconds.
• It is within the range of 200,000 (0.2 seconds) through 20,000,000 (20 seconds).
• The default value is 3,000,000 microseconds (3 seconds).

Before FlexNet Publisher11.13.1

Before FlexNet Publisher 11.13.1:

• The value of the environment variable is in microseconds.
• It is within the range of 0 through 2,147,483,647.
• The default setting is 100,000 microseconds.

In FlexNet Publisher 11.13.1 (FNP-10695)

Previously, the port@host format required an excessive time (of the order of seconds) to return an error, unlike the @host format. This was because the FLEXLM_TIMEOUT environment variable was inappropriately ignored with the port@host format.

This has now been resolved. For the default FLEXLM_TIMEOUT value of 100,000 (0.1 second), the error for both port@host and @host (when host is invalid) will be returned in less than a second.

In FlexNet Publisher 11.14.0 (FNP-11480)

FLEXLM_TIMEOUT is a Windows-only environment variable which sets the timeout value (in microseconds) that a Flex-enabled client application uses when attempting to connect to a license server.

Previously, the default value was 100,000 (0.1 seconds). Now, the default value is 3,000,000 (3 seconds), with a minimum value 200,000 (0.2 seconds) and maximum of 20,000,000 (20 seconds). An issue where timeout errors could inappropriately occur because of network latency between the client and the server (FNP-11480) was fixed through this change.

NOTE: The time to report a failure when attempting to connect to an invalid host from a Windows client is also governed by the FLEXLM_TIMEOUT value.
