I stumbled across this problem the other day whilst trying to setup a new Log Shipping configuration in SQL Server. The big difference in this environment, was that this implementation had DNS records in place to route the DR (Disaster Recovery) traffic via it’s own dedicated link. So for example, when specifying the database backup location,
An ongoing post detailing some everyday HP-UX commands…which I keep forgetting 😉 Check whether your server is 32-bit or 64-bit: # getconf KERNEL_BITS # print_manifest | grep “OS mode” Display network packets: # nettl -start # nettl -status all Memory details: # dmesg | grep -i physical # /usr/sam/lbin/getmem Swap info: # swapinfo (displayed in
The nmon (Nigel’s Monitor) tool was written initially for AIX to monitor system performance, but there are plenty of distributions available now so people can use it on a variety of operating systems these days, including flavours of Linux and even the recent Raspberry Pi (mini ARM based computer). It’s one of my favourite performance monitoring tools
Having only recently started using VirtualBox to build various VMs (Virtual Machines), it wasn’t immediately obvious to me how I could not only enable access to the outside world (Internet access, updates etc.), but also enable SSH to Linux boxes and such like via a private network within VirtualBox. Eventually, I decided to configure each
First of all, you need the OS installation media, which can be downloaded from the Oracle Software Delivery Cloud at http://edelivery.oracle.com/linux (login required). For this particular installation, I downloaded ‘Oracle Linux Release 6 Update 4 Media Pack for x86_64 (64 bit)’ which is listed as part V37084-01. In this instance, I then created a Virtual Machine using VirtualBox
Recently, I found myself in a situation whereby multiple database instances were running on a HP-UX clustered environment to ensure high availability, each with their own Serviceguard package, on an agent per package basis. Now on the plus side, if the SG package is failed over to another node, the agent goes with it, and
It’s been years since I stumbled across this, but today I was trying to launch a GUI from new Linux server and got this instead 🙁 X11 connection rejected because of wrong authentication. Error: cannot open display: localhost:12.0 So, I dug out my notes and thought it would make sense to then blog it for
After my first encounter with a HP-UX system recently, I soon discovered that annoyingly, neither the df -h or df -g commands work in HP-UX! There are other commands such as df -PK or bdf I’ve found that can provide you with a more readable view of the filesystems, but after a bit of faffing around, I put this together instead:
