Troubleshooting slow or missing awareness changes

The IBM® Sametime® Gateway server uses the Sametime Community Server Resolve mechanism for mapping email addresses.

About this task

For each resolve request, the Community Server accesses the LDAP directory. Receiving the response from the Community Server is time consuming. To provide a warning on unreasonable response times, the Gateway server collects resolve statistics. By default, the Gateway server provides a warning only if the response time of the resolve request is greater then 25 seconds. The warning time is configurable, and it is possible to change it by adding a custom property to the local community.

You can configure the Gateway server to provide a warning when user lookups take too long by using custom property resolver.stat, with the following values:

All - prints the response time of all resolve requests.
Number of seconds - Prints the response time of the resolve requests which are greater then the defined value.

For each 1000 identical messages, only the first five are printed to the SystemOut.log file. If there are more than five identical messages in the SystemOut.log file, the first five are printed individually, followed by a summary of the rest of the identical messages. See:
