Regexp error during Connections install

This week I installed IBM Connections 5.5CR1 on a Windows Server. I used WebSphere Application Server 8.5.5.9 and everything ran pretty smooth, but the Connections install itself ended in an error after all applications were successfully installed.

The popup showed a regexp error and a long string. The installer ran through the night, so I couldn’t remember this string and started the install again. The Same message box appears after everything was successfully installed (checked through ISC, after the error everything was uninstalled by the Installation Manager) and even the install.log showed nothing special.

This time, I remembered the string, it was the password of my WebSphere Administration user! The password looked like this:

960n4gv343te6f(

After removing the bracket and replaced it with another special character everything was installed without error. So be careful with special characters and IBM Installations.

I never had an issue with special characters, but I know that the Sametime documentation mentions that space, @ and ! can be a problem.

Missing images in Wikis after migration to IBM Connections 5.5

Wikis in IBM Connections 5.5 have a little bug, because the link (/library instead of /wikis/form/api/library) for images are wrong and so they are not displayed.

There is a technote, which should solve this issue, but the used way with ProxyPass is not what i want to use. When you use ProxyPass and ProxyPassReverse you should add a ProxyRequest off to be more secure. ProxyPass to localhost can be a problem too, i would suggest to change localhost to the Connections IHS Hostname.

Why do I use a different approach?

Most of my deployments already use a RewriteRule to redirect the hostname to there Connections Homepage, so i don’t need an additional module (which needs ressources and can have security considerations), when i can solve the image issue through mod_rewrite.

RewriteRule "^/library/(.*)" "/wikis/form/api/library/$1" [R,L]

If you haven’t set <forceConfidentialCommunications enabled="true"/> in LotusConnections-config.xml you need to set the RewriteRule and the ProxyPass config within your http and your https configuration parts!

Example httpd.conf:

... 
# HTTP configuration
<VirtualHost *:80>
    ServerName connections.example.com

    RewriteEngine On

     # Redirect hostname to Homepage
    RewriteRule ^\/$ https://connections.example.com/homepage [noescape,L,R]

    # Fix wrong wiki image URL
    RewriteRule "^/library/(.*)" "/wikis/form/api/library/$1" [R,L]
</VirtualHost>
# HTTPS configuration
<VirtualHost *:443>
    ServerName connections.example.com

    RewriteEngine On

    # Redirect hostname to Homepage
    RewriteRule ^\/$ https://connections.example.com/homepage [noescape,L,R]

    # Fix wrong wiki image URL
    RewriteRule "^/library/(.*)" "/wikis/form/api/library/$1" [R,L]

    SSLEnable
    SSLProtocolDisable SSLv2 SSLv3

IBM Connections – Communities Trash

Today i thought about creating and deleting some Communities with the REST API. Works really good and i need to post my findings sometimes.

First cool thing is that you can create restricted Communities with external feature through REST.

After deleting these Communities i checked the Community overview through my browser and found following view:

2015-12-15_20-45-47

So you mustn’t use wsadmin to restore Communities from trash, you can use this view. Never heared of it and the documentation still mentions wsadmin as the only way to restore them.

Social Connections 9 In Germany – Only Three Weeks Away

The next big IBM Connections Community event – Social Connections 9 – takes place November 05/06 in Ehningen / Germany. The theme of the event is “Working out loud” and it offers tons of sessions all around IBM Connections and Adoption in the social software world.

This will be my fifth Social Connections Event after Zurich, Prague, Stockholm and Boston, for me all of them were great experiences and personally very successful.

I have been working with ESS / ICS / Lotus products since 2000 and I followed many other community members through blogs, forums, web events and tweets, but I rarely had the chance to meet any of them in person. This changed with Social Connections V – I sent my first English session on the topic of scripting in IBM Connections and was accepted. I still can remember the warm welcome of Sharon, Klaus, Stuart, Simon, Femke, Sandra and Tim – it was phantastic!

There a some really good ESS events all around the globe, but my focus topic is best covered by Social Connections. I like the agenda with all the different topics it covers: announcements (René Schimmer will show IBM Connections next); Technic (master brains like Victor, Martin and Sjaak will speak); Deployment; Development (e.g. Paul and René); Use Cases (Alan Hamilton); or Adoption. And the best of all there is room to get the speaker personally for deeper discussion during the day and on the evening reception. Best chances for growing the own knowledge.

After “only” attending and speaking up until now, This time Ii got the chance to help organizing this event. So, for the last three months I had the honour of assisting Wannes, Stuart, Simon, Doug, Lars, Martin, Jan, Maria and Femke in creating “Social Connections 9”. It is my sincere wish that you will like this event as much as I enjoyed all the events I “only” participated in before.

This time I am presenting two sessions, one with Victor Toal on IBM Connections Administration and a renewed “Best and worst practises deploying IBM Connections”. I am looking forward to co-presenting with Victor – I think we are a funny, yet dynamic duo with strange German dialects (him Austrian and I Bavarian), but we will (try to) speak in English, so all the people can follow, not only Germans with a fair understanding of the more beautiful German dialects ….

So, this is enough of me, my opinions and an introduction into German dialects – you Can still register for this event and I urge you to if you have not done so yet – think of all the lovely folk you can finally meet and interact with!

Registration is still open and thanks to our great sponsors it will cost you only 179€ (excl VAT), which also covers the admission to the AWESOME gala reception.

What are you waiting for?
