Improving DNS Lookups on Linux
Tue, Oct 17th 2017 9:50a   Kenio Carvalho
A good DNS service is very important for a mail server. On Linux servers you need to put your DNS servers on a file called resolv.conf. In general you have two entries like this: nameserver1 192.168.10.10 nameserver2 10.10.1.1 If one server does not respond then linux will try the second, but there is a timeout for this: timeout:n Sets the amount of time the resolver will wait for a response from a remote name server before retrying the query via a different name server. This may not be t

How to resolve synchronization issues after upgrading to IBM Traveler 9.0.1.18 (or higher)
Fri, Sep 8th 2017 7:38p   Kenio Carvalho
IBM Traveler 9.0.1.18 enabled by default a feature that allows Traveler to “Run as a User” instead of as a server. This feature resolves several long standing issues with accessing the user’s data as the server ID. The last point above may cause sync issues for mobile users. If the access controls are inadvertently set to values that restrict individual users, but do not restrict the Traveler server, then users that could sync when running as the Traveler server ID might not be

Watson Conversation – Gathering information with slots
Fri, Jun 23rd 2017 1:17p   Kenio Carvalho
Add slots to a dialog node to gather multiple pieces of information from a user within that node. Slots collect information at the users’ pace. Details they provide upfront are saved, and the bot asks only for the details they do not. You can think of slots as the chat bot version of a web form in which users must fill out required fields before they can submit the form. Similarly, slots prevent the flow of conversation from moving on to a new subject until the required values are provided
