I was required to write a small listener. This listener doesn’t have to do anything fancy – it has to process input from a network source (over TCP) and shove it into a file with random name. The quick and dirty solution is to use netcat (nc). A short command such as this would do…

Setting up an Oracle ASM disks is rather simple, and the procedure can be easily obtained from here, for example. This is nice and pretty, and works well for most environments. EMC PowerPath creates meta devices which utilize the underlying paths, as mod_scsi sees them in Linux, without hiding them (unlike IBM’s RDAC, for example)….
I have encountered it on several cases. RedHat Linux ES, by default, uses smp kernel which is limited to eight cores, or two sockets. You find out that your multi-socket hardware, with its 16 (or more…) cores show you only the first eight, both by the simple method of running ‘top‘ and then pressing on…
Current servers are way more powerful than we could have imagined before. With quad-core CPUs, even the simple dual-socket servers contain lots of horse-power. Remember our attitude towards CPU power five years ago, and see that we’re way beyond our needs. When modern servers are equipped with at least eight cores, other, non-CPU related issues…
This is an interesting bug I have encountered: The output of an sssu command should look like this: EVA> DELETE STORAGE “Virtual DisksLinuxoracleSNAP_ORACLE” EVA> It still leaves the snapshot (SNAP_ORACLE in this case) visible, until the web interface is used to press on “Ok”. This happened to me on HP EVA with HP StorageWorks Command…
