Automatic WebSphere plugin modification II – PowerShell for Windows
Thu, Dec 1st 2016 6:54p   GIS Techblog
Automatic WebSphere plugin modification II – PowerShell for Windows Hi, 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: modifywasplug

IBM Connections Docs – file preview not possible for some CCM pdf files Hi all, 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.

IBM Connections – How to switch to a custom global unique ID for users

IBM Connections – How to switch to a custom global unique ID for users Hi, many of our todays support cases is related to non-working profiles in IBM Connections. If users change their name, switch from one to another location or simply get a new account their profile in IBM Connections might get inactivated because the hash key between LDAP and database has changed. There are three possible hash keys: UID: Often a bad choice, as this might change eMail: Also a bad choice GUID: Unique I

IBM Connections – add additional login attribute

IBM Connections – add additional login attribute Hi, last week I got the question if it is possible to use another login attribute for IBM Connections than uid, cn or email. Yes, this is possible and can be done very easy. It just needs some small adjustments (I assume that you already extended your LDAP schema and that the custom attribute is available in LDAP!!): 1. Open a wsadmin session ./wsadmin -lang jacl 2. Make a custom login attribute from LDAP known to the PersonAccount entity:

IBM Connections – Set read-only access to CCM libraries Hi, we are in the middle of several migrations to IBM Connections 5.5 and most of our customers come up with the question: What do I need CCM for if I can use nested folders in Files now? Many customers decide to manually migration CCM libraries to Files… This time a customer asked us if it is possible to set access to libraries to read-only so that no new files or folders are added to CCM. This is possible using the following

Why you should always use DBT for transferring IC databases…

Why you should always use DBT for transferring IC databases... Hi, when talking about migrating IBM Connections from an old to the current release you have to think about migrating databases from the old to the new environment (in case you do a side-by-side migration – which is recommended if you migrate a production environment). You have two options to do such a migration: db2 backup on the old server and restore on the new server use the dbt.jar tool to transfer databases I always per

Hi all, 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 yo

Automatic modification of WebSphere Plugin (Primary / BackupServers) to maintain two-line concept
Wed, Jul 6th 2016 8:58a   GIS Techblog
Automatic modification of WebSphere Plugin (Primary / BackupServers) to maintain two-line concept Hi, in larger highly available environments you may know an architectural concept called “two-line approach”. Behind a load balancer you have two lines that can be shutdown / started independent from each other. This is very practical if you need to do maintenance to the operation system or other system related things without the necessity to always shutdown the complete environment. In

IBM Connections 5.5 – Problem with ibm_upload_module and NFS
Mon, Jul 4th 2016 10:50a   GIS Techblog
IBM Connections 5.5 – Problem with ibm_upload_module and NFS Hi, since IBM Connections 5.5 there is an IHS module available that handles file uploads via HTTP Server and not via WebSphere Application Server – similar to the module for downloading files. This has great advantages in terms of performance and memory usage, because WAS does not need to take care about serving those files via JVM. But I ran into trouble when using this module in combination with Linux and a standard confi
