IntroductionStarting with my “CentOS 6 + EMS” setup, I need to obtain a decent FT/HA demo setup for test purposes.My clients are often trying to improve EMS availability in case of a disaster or simple software error. Not because EMS itself is unstable, but mostly to manage risk related to MOM RollOver(or FT), HA and DR. TIBCO does provides guidelines on the subject, but not precise recommendation on the combination of OS and distributed FS to use. Additionally, TIBCO experts usually push for file stores over DB stores. They state that DB stores should not be considered for perform ...继续阅读 (44)

Here is a nice week-end project, useful for automatic presentations, restaurant menus and waiting room video entertainment/marketing/information (my case).I used a 32″ TV with a Raspberry Pi B (512 Mb RAM), a Wifi Adapter and a 64 Gb SD card (40 $CND at Costco) to create a simple video looping device.My goal is simple, I want to use SFTP to upload videos in a folder, and have a simple Debian service loop and play each video file one by one.Since I am not always here to restart the service, a simple reboot of the Pi (by unplugging) should restart the whole thing. No technical knowledge re ...继续阅读 (43)

This is my first article on TIBCO NOW 2014.Again this year, I was sent as a technology observer bymy employer (Logimethods)to assess the new product line and business orientations of TIBCO.This year was a great one.The TIBCO folks have improved and refined their orientations on a handful of their core topics : Integration, Analytics, Data Management (second article on the way), and revamped their product line in a massive (good !) way (third article on the way).Before I start writing on all these turn of events, I want to start by answering many of my colleagues & clients questions about the T ...继续阅读 (19)

In my recentexperiments, and while preparing for my next post, I stumbled on problems when trying to forward ports of my CentOS Guest VM to my Mac OS based browser. For some reason, even if Port forwarding was properly configured, like so :Virtual Box Port NAT port forwarding on CentOS…my Host system browser could not connect to services on my VM, with the exception of SSH. The solution was simple, CentOS comes with default netfilters rules built-in. These rules allow outgoing trafic, and incoming SSH requests only. The firewall configuration needed to be changed. The simplest way to do ...继续阅读 (59)

.ova Conversion to .vmk and .vmdkToday I learned that the “.ova” packages provided by some vendor for VMWare ESX are from anopen standard (OVF).There is an existing VMWare tool (OVFTool) that can be used to convert any such “.ova” file to easily runable “.vmk” files.The usage is simple enough :ovftool.exe SOME_OVA_FILE.ova NEW_VMKNAME.vmkI found the original information inthis simple how-to.Virtual box image creationNote : For some reason, a “direct import” of the .ova file in Virtual Box would always fail… hence this very manual tutorial.T ...继续阅读 (39)
