After I set up OpenSolaris 2009.06 (see my previous posts) on my openSuSE 11.2 dom0 I was keen to set up Oracle 11.2 single instance on ZFS. ZFS is a new-ish filesystem and successor to ufs no Solaris 10. I like it a lot for simplicty and ease of use. Piet de Visser should love it too :)
But before I could start working on this I needed to do some prep work.
Storage preparation on the dom0
Very simple-I created 2 more zero padded files in my domU base directory and added those to the domU configuration file, as in:
disk = [ "file:/m/xen/osol/system,xvda,w", "file:/m/xen/osol/oracle_bin,xvdb,w", "file:/m/xen/osol/oracle_data,xvdc,w", ] vif = [ "mac=00:16:3e:1b:e8:18,bridge=br1,script=vif-bridge" ]
Be sure to add a MAC address to your configuration file or otherwise Solaris will cry out loud the next restart claiming the new storage pool has been used with a different system. That’s not a problem (can be fixed with zpool import -f) but it’s not pretty either.
Addition of new storage pool
This is really simple! First of all you need to find out which of the disks presented to the system are the new ones. I only used 1 disk for the rpool (default storage pool), so I tried to identify this one first:
root@opensolaris:~# zpool status rpool pool: rpool state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM rpool ONLINE 0 0 0 c7t0d0s0 ONLINE 0 0 0 errors: No known data errors
Then I identified the disks on the system:
root@opensolaris:~# format Searching for disks...done AVAILABLE DISK SELECTIONS: 0. c7t0d0 <DEFAULT cyl 4095 alt 0 hd 128 sec 32> /xpvd/xdf@51712 1. c7t1d0 <Unknown-Unknown-0001-10.00GB> /xpvd/xdf@51728 2. c7t2d0 <Unknown-Unknown-0001-10.00GB> /xpvd/xdf@51744 Specify disk (enter its number): ^C root@opensolaris:~#
So, not really surprisingly, c7t1d0 and c7t2d0 were the new disks. I created a new storage pool “oraclepool” with these 2 disks (not recommended for production!)
root@opensolaris:~# zpool create oraclepool c7t1d0 c7t2d0
root@opensolaris:~# zpool status -v
pool: oraclepool
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
oraclepool ONLINE 0 0 0
c7t1d0 ONLINE 0 0 0
c7t2d0 ONLINE 0 0 0
errors: No known data errors
pool: rpool
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
rpool ONLINE 0 0 0
c7t0d0s0 ONLINE 0 0 0
errors: No known data errors
With that done, I created a few file systems:
- oraclepool/binaries
- oraclepool/oradata
zfs create oraclepool/oradata zfs create oraclepool/binaries
By default these are mounted to poolname/fs name, i.e. /oraclepool/oradata which isn’t too convenient. Luckily, zfs allows you to easily change the mountpoint without touch /etc/vfstab (which isn’t recommended anyway).
So, enter these commands to change the mountpoints:
zfs set mountpoint=/u01 oraclepool/binaries zfs set mountpoint=/u01/oradata oraclepool/oradata
The final layout prior to the installation was as follows:
zfs set mountpoint=/u01 oraclepool/binaries root@opensolaris:~# zfs list NAME USED AVAIL REFER MOUNTPOINT oraclepool 7.98G 11.6G 19K /oraclepool oraclepool/binaries 6.68G 11.6G 6.68G /u01 oraclepool/oradata 1.30G 11.6G 1.30G /u01/oradata rpool 5.27G 2.55G 77.5K /rpool rpool/ROOT 3.01G 2.55G 19K legacy rpool/ROOT/opensolaris 3.01G 2.55G 2.87G / rpool/dump 256M 2.55G 256M - rpool/export 2.22M 2.55G 21K /export rpool/export/home 2.20M 2.55G 1.63M /export/home rpool/export/home/martin 584K 2.55G 584K /export/home/martin rpool/swap 2G 4.08G 474M -Oracle user creation
Create the oracle user as always, I did the following:
- groupadd oinstall
- groupadd dba
- useradd -g oinstall -G dba -d /export/home/oracle -s `which bash` -m oracle
- chown -R oracle:oinstall /u01
- projadd -U oracle -K “project.max-shm-memory=(priv,4096MB,deny)” user.oracle
- projmod -s -K “project.max-sem-ids=(priv,256,deny)” user.oracle
Set static IP
Edit /etc/hosts to include your hostname, then edit /etc/nwam/llp to include your network interface, the keyword “static” and the ip/netmask.
My example uses:
root@opensolaris:~# cat /etc/nwam/llp xnf0 static 192.168.99.11/24
Change Swap
It’s necessary to increase swap space or otherwise the ld will fail during the “linking phase”. I increased to 2G from 512M:
root@opensolaris:~# zfs get volsize rpool/swap NAME PROPERTY VALUE SOURCE rpool/swap volsize 512M - root@opensolaris:~# zfs set volsize=2G rpool/swap root@opensolaris:~# zfs get volsize rpool/swap NAME PROPERTY VALUE SOURCE rpool/swap volsize 2G -
Oracle Installation
We need to create a symlink for -lcrypto, otherwise one of the shared libraries won’t link with a missing reference to “-lcrypto”:
ln -s /lib/amd64/libcrypto.so /usr/sfw/lib/amd64
Run the installer in silent mode – I modified one of the response files and simply executed ./runInstaller -silent -debug -fore -responseFile /path/to/responseFile.rsp -ignoreSysPrereqs
Database Creation
I ran dbca in silent mode as oracle as follows:
cd /u01/app/oracle/product/11.2.0/dbhome_1/ export ORACLE_HOME=`pwd` cd bin ./dbca -silent -createDatabase -gdbName orcl \ -templateName General_Purpose.dbc -emConfiguration none \ -datafileDestination /u01/oradata -sysPassword xxx \ -systemPassword xxx -storageType FS -initParams \ filesystemio_options=setall
Success!
