Using double dash to specify pesky command line parameters

Many Linux commands accept command-line options and positional parameters. The grep command searches for a pattern in a given file. Its 2 positional parameters are the pattern and the filename.

This makes the parameter indistinguishable from an option. For example, you try to grep the string -tea in a given file.

SLOB full table scans

A short post in follow-up to the previous one on ZFS vs ASM:
I wrote that I had to create a procedure to get full table scans on SLOB data. SLOB is designed to do random I/O (and lots of it ;-) but my test required FTS as well.

Oracle ASM vs ZFS on XtremIO

In my previous post on ZFS I showed how ZFS causes fragmentation for Oracle database files. At the end I promised (sort of) to also come back on topic around how this affects database performance.
