||DB2 Instance autostart does not work on SLES 12 / RHEL 7
I had to fight with a customer environment on SLES 12 where the db2 instances did not start automatically when starting the operation system.
db2iauto -on db2inst1
was executed but the instance did not come up! The problem is related to the DB2 fault monitor that is not started automatically on system start.
The fault monitor permanently monitors the instance and automatically restarts it after a crash. Furthermore, the fault monitor can auto restart an instance on machine reboot. If you issue „db2stop“ then the fault monitor will NOT start the instance automatically again – but this is the only exception.
In total a good mechanism – but useless when using TSAMP / HACMP Cluster Software because in this case the restart of an instance is controlled by this kind of software.
On pre SLES 12 / RHEL 7 systems the fault monitor is started using inittab:
The entry was available on this system…
But on SLES 12 / RHEL 7 systemd replaces the default init system. This entry in inittab is not executed anymore.
You need to configure a service for the fault monitor be to started when the operating system starts – IBM already created a technote for this:
1) create a service file in the folder
2) input the following content:
This tells the systemd daemon to start the db2 fault monitor on system start. Furthermore „Restart=always“ tells the daemon to restart the service if it terminates abnormally.
3) execute the following command to refresh the configuration
4) execute the following command to enable the service
systemctl enable db2fmcd
5) execute the following command to start the service
systemctl start db2fmcd
Now you need to login as your instance owner and set the instance to automatically start upon operating system start
db2iauto -on db2inst1
Check the setting using
Restart the operating system to check if your change was successful.
If you want to start your application / HTTP servers automatically on operating system start you should also use systemd – once you understood the concept behind it is a powerful and better init system than the old one from the previous SLES / RHEL versions.

Exchange integration into WebSphere Portal (SSO – Kerberos)|

Exchange integration into WebSphere Portal (SSO – Kerberos)
During the last years working with Portal I had several challenges with WebSphere Portals HTTP Outbound Proxy (aka. Ajax Proxy) in terms of authenticating backend calls to various other systems.
What we`ve done so far in terms of SSO / backend authentication:
– Authenticating using LTPAToken
– Authenticating using SAML
– Authenticating using SPNEGO / Kerberos (this was a new one for me)
The challenge this time

User provisioning for IBM Connections Cloud – You have the choice
Customers who use IBM Cloud for Connections, Sametime or other applications face the problem to manage their cloud accounts. For some single users you can use the Web frontend to add or change user accounts or to assign subscriptions and licenses to users. But in real world scenarios it is not possible to manage thousands of users manually or to keep them synchronized with an on-prem user repository or LDAP.
This can be handled
SAML & IBM Connections 5.5 – not a dream team|
Fri, Aug 18th 2017 7:45a GIS Techblog
last week we had to fight with an activation of SAML on a IC 5.5 CR3 environment.
The setup was:
IBM Connections 5.5 CR3 as test instance
ADFS Server 3.0 (I know… it is only tested with ADFS 2.0 – but works with 3.0 too)
We followed the instructions from the IBM Connections Knowledge Center. Smooth setup everything standard procedure. When testing this setup, the redirect to the IdP was initiated. After logging into the IdP the browser was redirected to IBM Connections ACS

IBM Docs – Migration from DB2 –> ORACLE
within our last big project, we had the challenge to transfer the IBM Docs database from DB2 to ORACLE. Within this database comments and other document related data is stored.
Officially there is no script available to perform this move using DBT (remove constraints / transfer / reapply constraints). We looked into the database and figured out how to perform this task using DBT – so we are not dependent on any other products. We m

IBM Connections – trouble adding additional nodes
we are currently involved in a project where we installed a 1 node IBM Connections 6 Cluster and later added a second node to the cell.
So far so good… Everything that needs to be done after adding the second node is described here … Everything? Yes, mainly… but not in the mandatory details as I think! Missing custom properties and other settings might result in non-functional nodes. Especially not setting httpSess

SNOUG 2017 Presentation – SikaConnect goes External
yesterday I was at SNouG in Zurich. I had a great time there – good speakers and a overall perfectly organized event (would we expect sth. else from Switzerland? )

Whiteboard in IBM Sametime Meeting 9.0.1 removed
IBM implemented in Sametime Meeting 9.0.1 a whiteboard function as technical preview. Ben described in his articel how to enable this feature:
With the current cumulative Fix 901-ST-General-FP-SMOL-AK4G43 for the Meeting Server IBM has removed this function.
The response on my PMR was:
“I can confirm The Meetings Whiteboard feature release is being put on hold indefinitely.

Wikis content not accessible…
it`s been quite a long time; many projects at the moment so that blogging needs to wait
Last week we had a very interesting problem at one customer’s environment. When accessing a Wiki, the page was displayed blank – no content was available. Browsing to older versions of this wikis worked.
The error in the log:
Parsing error… Wikis content (the body) gets store in the filesystem as xml files. If you access a Wiki there is a XML parser

Automatic WebSphere plugin modification II – PowerShell for Windows
some months ago I published a shell script to automatically modify the Primary / BackupServer definition in a WebSphere plugin-cfg.xml file.
As we have several Windows customers we decided to transfer this script to PowerShell so that it is also useable for a Windows Cluster installation. My colleague Jan Bruns did a great job implementing this script.
It basically works the same way as the Linux script:

IBM Connections Docs – file preview not possible for some CCM pdf files
last week we had trouble in a customer environment using the file preview functionality for some pdf files (only those that were uploaded using CCM).
Instead of a preview the message was displayed:
At the same time we saw the following warning in the log:
The mime-type was set to “image/pcl” instead of “application/pdf”… this mime-type is not supported by IBM Docs File viewer. We had to dig deep into th
