if this is going to host prod DBs and you'll be running them in archive log mode, you need to consider how you'll distribute the I/O on your disks. we have the archive logs and DBs on the same set of disks before and had some I/O issues during RMAN backup runs. and for the swap size, we tried to minimize swapping as much as we can.
Yes this will be used for production and will be housed in internal disks. What raid type you recommend 0+1 or raid 5 for better performance? BTW are you using kickstart server with standard image for Oracle in blade deployment? On other *nix with regards to RMAN we usually schedule this when the system is not at its busiest hours to avoid this problem and we zoned a separate hba for this purpose.
here's the LVM layout that we use in our kickstart files for oracle db servers: #part /boot --fstype ext3 --size=100 --ondisk=cciss/c0d0 #part pv.100000 --size=100 --grow --ondisk=cciss/c0d0 #volgroup vg00 --pesize=32768 pv.100000 #logvol /var --fstype ext3 --name=lvsys03 --vgname=vg00 --size=512 #logvol /opt --fstype ext3 --name=lvsys04 --vgname=vg00 --size=512 #logvol /tmp --fstype ext3 --name=lvsys05 --vgname=vg00 --size=1536 #logvol /home --fstype ext3 --name=lvsys06 --vgname=vg00 --size=256 #logvol /local --fstype ext3 --name=lvdata01 --vgname=vg00 --size=1024 #logvol /usr --fstype ext3 --name=lvsys02 --vgname=vg00 --size=2048 #logvol / --fstype ext3 --name=lvsys00 --vgname=vg00 --size=256 #logvol swap --fstype swap --name=lvsys01 --vgname=vg00 --size=8192
This is a nice minimalist / set-up, do you have X in this setup? What are the important packages you usually include with this set-up?
these are all in the internal disks (with internal raid) of our blade machines. the FS for our DBs (and oracle itself) are hosted on SAN disks with the LVs created with at least 4 stripes.
I would really like to hosts the other filesystem in the SAN because its more flexible to carved out luns for filesystems. We are also booting on SAN but not yet on RHEL. thanks, -- sometimes truth is stranger than fiction -bad religion- http://www.bloglines.com/blog/mailist _________________________________________________ Philippine Linux Users' Group (PLUG) Mailing List [email protected] (#PLUG @ irc.free.net.ph) Read the Guidelines: http://linux.org.ph/lists Searchable Archives: http://archives.free.net.ph
