Using cpio

Malcolm Chalmers — Tue, 09 Feb 2010 01:49:08 +0000

Some files that you get from Oracle download come in cpio format. Here’s what to do with them. First unzip the files:

gunzip lnx_920_disk1.cpio.gz gunzip lnx_920_disk2.cpio.gz gunzip lnx_920_disk3.cpio.gz

Next unpack the contents of the files:

cpio -idmv < lnx_920_disk1.cpio cpio -idmv < lnx_920_disk2.cpio cpio -idmv < lnx_920_disk3.cpio

Prtdiag is Not working in Solaris

Malcolm Chalmers — Wed, 03 Feb 2010 20:00:51 +0000

Try running it as root. If this works then check the permisions on /var/run/picld_door

The permisions should be set to 444 ie:

ls -l /var/run/picld_door Dr--r--r-- 1 root root 0 Aug 27 07:40 /var/run/picld_door

This is the fix:

shell> chmod 444 /var/run/picld_door

There is a “Renaming Wizard” of the site to show you how to rename the file to get different outputs.
