Openshift - Moving gears from one node to another

AFAIK, this can only by done by the root on the broker node.

broker ~ # oo-admin-move --help
== Synopsis

 oo-admin-move: Move an app from one node to another

 == Usage

 oo-admin-move OPTIONS

 Options:
--gear_uuid
    Gear uuid to move
--destination_district_uuid
    Destination district uuid
-i|--target_server_identity
    Target server identity
-p|--node_profile
    Node profile
-t|--timeout
    timeout
--change_district
    Move to a different district other than the source district
-h|--help
    Show Usage info


So first, we must obtain the gear ID list. And choose which gear we want to move.

rhc app show --gear -a appname -n appdomain

Then we need to specify the destination node FQDN (fully qualified domain name) and the gear uuid in the broker's root console.

oo-admin-move --gear_uuid zzzzzzz -i nodetarget.domain.com

Example result :


broker ~ # oo-admin-move --gear_uuid 54f7c4e398988bb221000083 -i node2.aon.telkom.co.id

Long running process in Linux using PHP

Background To do stuff, I usually create web-based applications written in PHP. Sometimes we need to run something that takes a long time, far longer than the 10 second psychological limit for web pages. A bit of googling in stack overflow found us this  http://stackoverflow.com/questions/2212635/best-way-to-manage-long-running-php-script , but I will tell the similar story with a different solution. One of the long running tasks that need to be run is a Pentaho data integration transformation. Difficulties in long running PHP scripts I encountered some problems when trying to make PHP do long running tasks : PHP script timeout. This could be solved by running set_time_limit(0); before the long running tasks. Memory leaks. The framework I normally use have a bit of memory issues, this can be solved either by patching the framework (ok, it is a bit difficult to do, but I did something similar in the past ) or splitting the data to process into several batches. And if you

Reverse Engineering Reptile Kernel module to Extract Authentication code

Image
 This time I will show how to (partially) reverse engineer a linux kernel module. The linux kernel module is larger than usual kernel module because it is actually a Reptile-based rootkit dropped by some hacker.  Part 1. Get basic module information First we gather basic module info by using modinfo : [root@lb lkrg-0.9.1]# modinfo falc0n filename:       /lib/modules/3.10.0-1127.10.1.el7.x86_64/kernel/sdc/falc0n.ko intree:         Y license:         GPL retpoline:       Y rhelversion:     7.8 srcversion:     81F508029A53F7490CCDB44 depends:         vermagic:       3.10.0-1127.10.1.el7.x86_64 SMP mod_unload modversions   We could also refer to the kernel module file not yet installed in the OS : [root@lb lkrg-0.9.1]# file falc0n.ko falc0n.ko: ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), BuildID[sha1]=1bde6abf4732eb620983032a47fbcf07689ece11, not stripped [root@lb lkrg-0.9.1]# modinfo falc0n.ko filename:       /root/lkrg-0.9.1/falc0n.ko intree:         Y license:         GPL retp

SAP System Copy Lessons Learned

Image
Background Earlier this year I was part of a team that does System Copy for a 20 terabyte plus SAP ERP RM-CA System. And just now I am involved in doing two system copy in just over one week, for much lesser amount of data. I think I would note some lessons learned from the experience in this blog. For the record, we are migrating from HP/UX and AIX to Linux x86 platform. Things that go wrong First, following the System Copy guide carefully is quite a lot of work - mainly because some important stuff are hidden in references in the guide. And reading a SAP note that are referenced in another SAP note, that are referenced in Installation Guide.. is a bit too much. Let me describe what thing goes wrong. VM Time drift The Oracle RAC Cluster have time drift problem, killing one instance when the other is shutting down. The cure for our VMWare-based Linux database server is hidden in SAP Note 989963 "Linux VMWARE Timing", which is basically add a tinker panic 0 in the
