Several weeks ago a customer launch his new WebSphere Portal after  migrating from WPS 7.0.  We change the database server from Db2 to Oracle RAC but… WebSphere Portal has support for Oracle RAC.  We ask the Oracle DBA team for the connection URL and he sent an URL like this one: jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=HOSTNAME)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=SERVICENAME)) The url for Oracle RAC is like this one: jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(
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 nameserver2 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

Wed, Sep 20th 2017 9:34a   Kenio Carvalho
From Open Liberty Blog A modern runtime for Java microservices Over the last year we have had a lot of discussions with developers about how Liberty needs to evolve in order to meet developers’ expectations, and to continue innovating to support modern application needs. Of course, what ‘modern’ means in this context is always changing and microservices are redefining how software is developed. This is why we have been so active in the Eclipse MicroProfile project which is helping to
Fix Available for SMTP regression issue in Domino 9.0.1 FP9
Fri, Sep 15th 2017 8:15p   Kenio Carvalho
An issue was introduced in Domino 9.0.1 FP9 that could result in SMTP mail headers with random characters inserted into From, Sendto, and Copyto fields.

How to resolve synchronization issues after upgrading to IBM Traveler (or higher)
Fri, Sep 8th 2017 7:38p   Kenio Carvalho
IBM Traveler 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
