NetBSD supports Solaris/SVR4 binary emulation. This means that NetBSD/SPARC is able to execute Solaris/SPARC binaries – IOU, for example. http://www.netbsd.org/docs/compat.html http://netbsd.gw.com/cgi-bin/man-cgi?compat_solaris+.sparc+NetBSD-5.1 NetBSD/SPARC runs on qemu-system-sparc. Solaris emulation requires some real Solaris libraries. Libraries from any 32-bit Solaris/SPARC should work. Solaris 8 works. Solaris 10 does not work. Here’s a quick tutorial: 1. Compile qemu-system-sparc. 2.… Leer más »

The iostat(1M) utility provides several I/O statistics, which can be useful for analyzing I/O workloads and troubleshooting performance problems. When reviewing I/O problems, I usually start by reviewing the number of reads and writes to a device, which are available in iostat’s “r/s” and “w/s” columns: $ iostat -zxnM 5 extended device statistics r/s w/s… Leer más »

Understanding ZFS: Transaction Groups & Disk Performance 23 Jan ’09 – 06:42 by benr I’ve been deeply concerned about the number of people who continue to use iostat as the means to universally judge IO as «good» or «bad». Before I explain why, lets review iostat. # iostat -xnM c0t1d0 1 extended device statistics r/s… Leer más »

Solaris vi input mode arrow keys fix This blog post is not for you to read. It’s for me. You see, every once in a awhile, I work for a client/employer who uses Solaris, OpenSolaris, Unix, or some other traditional Unix-like OS. They have their reasons, and they are good ones, and I’m fine with… Leer más »

Introduction to iostat , vmstat and netstat

La única diferencia con la que nos encontramos, es que en Solaris el editor por defecto para crontab es ed, que hace que la edición del crontab se haga infumable. Así que antes de editar el crontab hay que definir en la variable del sistema EDITOR, que editor queremos utilizar, en mi caso vi. export… Leer más »
