Oracle Zone

Setup Oracle Database on a Solaris zone with CPU limit

Our setup is a 48GB x86-Server

Limit ZFS ARC

Add to /etc/system: <syntaxhighlight lang=bash> set zfs:zfs_arc_max = <bytes as hex value> </source>

To calculate your own value: <syntaxhighlight lang=bash>

  1. LIMIT_GB=8 ; printf "*\n** Limit ZFS ARC to %dGB\n*\nset zfs:zfs_arc_max = 0x%x\n" ${LIMIT_GB} $[${LIMIT_GB} * 1024 * 1024 * 1024]
    • Limit ZFS ARC to 8GB

set zfs:zfs_arc_max = 0x200000000 </source>

Create Zone

Set values: <syntaxhighlight lang=bash> ZONENAME=oracle ZONEPOOL=rpool ZONEBASE=/var/zones MAX_SHM_MEMORY=30G LOCKED_MEMORY=30G MAX_PHYS_MEMORY=34G SWAP=${MAX_PHYS_MEMORY} NUMBER_OF_CPUS=2 </source>

Create zone with <syntaxhighlight lang=bash> zfs create -o mountpoint=none ${ZONEPOOL}/zones zfs create -o compression=on -o mountpoint=${ZONEBASE}/${ZONENAME} ${ZONEPOOL}/zones/${ZONENAME} chmod 700 ${ZONEBASE}/${ZONENAME} printf " create set autoboot=true set zonepath=${ZONEBASE}/${ZONENAME} add dedicated-cpu set ncpus=${NUMBER_OF_CPUS} end add capped-memory set swap=${SWAP} set physical=${MAX_PHYS_MEMORY} set locked=${LOCKED_MEMORY} end set scheduling-class=FSS set max-shm-memory=${MAX_SHM_MEMORY} verify commit " | zonecfg -z ${ZONENAME} -f -

</source>

Enable dynamic pool service to add support for dedicated-cpus: <syntaxhighlight lang=bash> svcadm enable svc:/system/pools/dynamic </source>

Install and boot: <syntaxhighlight lang=bash> zoneadm -z ${ZONENAME} install zoneadm -z ${ZONENAME} boot zlogin ${ZONENAME} usermod -s /bin/bash root zlogin ${ZONENAME} </source>

CPU-check: <syntaxhighlight lang=bash> -bash-3.2# psrinfo -pv The physical processor has 2 virtual processors (0 1)

 x86 (chipid 0x0 GenuineIntel family 6 model 44 step 2 clock 3059 MHz)

Intel(r) Xeon(r) CPU X5675 @ 3.07GHz </source>

Create ZPools

I used this paper: [1] Values are for Solaris 10.

<syntaxhighlight lang=bash> DATABASEPOOL=dbpool DATABASEPOOL_DATA_VDEV="mirror c1t1d0 c1t2d0" DATABASEPOOL_ZIL_VDEV="mirror c1t3d0 c1t4d0"

REDOPOOL_NAME=redopool REDOPOOL_DATA_VDEV="mirror c1t5d0 c1t6d0" REDOPOOL_ZIL_VDEV="mirror c1t7d0 c1t8d0"

ARCHIVEPOOL=archivepool ARCHIVEPOOL_DATAV_DEV="mirror c1t9d0 c1t10d0"

DB_BASEPATH=/database DB_BLOCK_SIZE=8192 </source>

<syntaxhighlight lang=bash> zpool create ${DATABASEPOOL} ${DATABASEPOOL_DATA_VDEV} log ${DATABASEPOOL_ZIL_VDEV}

zfs create -o recordsize=${DB_BLOCK_SIZE} -o mountpoint=${DB_BASEPATH}/data ${DATABASEPOOL}/data zfs set logbias=throughput ${DATABASEPOOL}/data

zfs create -o recordsize=${DB_BLOCK_SIZE} -o mountpoint=${DB_BASEPATH}/index ${DATABASEPOOL}/index zfs set logbias=throughput ${DATABASEPOOL}/index

zfs create -o mountpoint=${DB_BASEPATH}/temp ${DATABASEPOOL}/temp zfs set logbias=throughput ${DATABASEPOOL}/temp

zfs create -o mountpoint=${DB_BASEPATH}/undo ${DATABASEPOOL}/undo zfs set logbias=throughput ${DATABASEPOOL}/undo </source>

<syntaxhighlight lang=bash> zpool create ${REDOPOOL} ${REDOPOOL_DATA_VDEV} log ${REDOPOOL_ZIL_VDEV}

zfs create -o mountpoint=${DB_BASEPATH}/redo ${REDOPOOL}/redo zfs set logbias=latency ${REDOPOOL}/redo </source>

<syntaxhighlight lang=bash> zpool create ${ARCHIVEBASEPOOL} ${ARCHIVEPOOL_DATA_VDEV}

zfs create -o compression=on -o mountpoint=${DB_BASEPATH}/archive ${ARCHIVEBASEPOOL}/archive zfs set primarycache=metadata ${ARCHIVEBASEPOOL}/archive </source>
