Solaris 11.4 SRU27 with Zones Sheet on the Dashboard

Solaris 11.4 GA was released in 08/2018. Since then Oracle published an update (SRU) each month.


We are now at SRU27 (November 2020). This new SRU contains a bunch of new features.

My favorite is the Zones Sheet where you can see how the Resource Usage of your zones is.

Solaris 11 Upgrade on Veritas Cluster with Failover Zones

For efficient Solaris 11 upgrades on Veritas Cluster do the following

1. Disable Evacuation of the Solaris Zones

/opt/VRTSvcs/bin/hagrp -modify myzone_sg Evacuate 0

After the Solaris 11 Upgrade and reboot the Zones are not evacuated to the other Cluster Node.

2. Double check AutoStartList

Check and set the AutoStartList of your Solaris Zones Service Group to make sure
the Zones are attached to the same Node they are currently running on.

/opt/VRTSvcs/bin/hagrp -modify myzone_sg AutoStartList node1 node2


With this setup you can upgrade your first node, reboot and verify all Zones are running fine.

pkg update --be-name s11.3.36 entire@0.5.11,5.11-0.175.3.36
init 6

If all is well with your Solaris Zones and Apps you can do the same with your second node.
 

And after all your nodes are upgraded you can enable Evacuation again.

/opt/VRTSvcs/bin/hagrp -modify myzone_sg Evacuate 1


Happy Upgrading ..

Why we are using SPARC LDoms

Oracle and Fujitsu SPARC Servers include the LDoms Technology. There are no additional costs.
If you see the "Marketing" name 'Oracle VM Server for SPARC'. That is exactly this LDoms Technology.

You can create individual Domains with dedicated CPU and RAM resources running
different Solaris Releases. Use of CPU and RAM is very efficient, because there is no software layer involved. You can add and remove CPU and RAM while the LDoms is running!

Access to Disk and Network can be done virtualized. Performance is good. Using such a virtualized setup the Domains can be live migrated between Servers with the same type of CPU. You can cold migrate (with downtime) between different types of Server in a few minutes.

You place different customers and applications in different LDoms. Good aproach to consolidate your environment.

We at JomaSoft use this technology very successful since years ourselfs and at customer sites.
Our VDCF tool makes deployment and management of LDoms very easy.

Performance Impact of ZFS Encryption on Oracle Solaris

Transparent Encryption is very easy to use on Oracle Solaris.
You just need to set the encryption property when you create a new filesystem and provide a passphrase or keyfile.

On a SPARC S7 LDom we have 3 ZFS filesystems with different encryption settings.

# zfs get encryption v0123_db/plain v0123_db/encr v0123_db/encr256
NAME              PROPERTY    VALUE        SOURCE
v0123_db/encr     encryption  on           local
v0123_db/encr256  encryption  aes-256-ccm  local
v0123_db/plain    encryption  off          -

Now lets see how much is the difference in write performance if we copy a 1 GB file.

# ls -lh p25604852_1100_Solaris86-64_1of4.zip
-rw-r--r--   1 marcel   staff       1.3G Apr  7  2017 p25604852_1100_Solaris86-64_1of4.zip
#

# time cp p25604852_1100_Solaris86-64_1of4.zip /plain

real    0m8.829s
user    0m0.002s
sys     0m1.711s

# time cp p25604852_1100_Solaris86-64_1of4.zip /encr

real    0m9.229s
user    0m0.002s
sys     0m1.747s

# time cp p25604852_1100_Solaris86-64_1of4.zip /encr256

real    0m9.733s
user    0m0.002s
sys     0m1.754s

The difference is a low one digit percent value.

Performance impact is a little larger when doing a simple read test.

# time cp /plain/p25604852_1100_Solaris86-64_1of4.zip /tmp

real    0m4.216s
user    0m0.002s
sys     0m3.810s

# time cp /encr/p25604852_1100_Solaris86-64_1of4.zip /tmp

real    0m5.131s
user    0m0.003s
sys     0m5.028s

# time cp /encr256/p25604852_1100_Solaris86-64_1of4.zip /tmp

real    0m5.400s
user    0m0.003s
sys     0m5.287s

Oracle Database on Solaris ZFS done right

ZFS is the default filesystem on Oracle Solaris. It is
very easy to use with the two commands zpool and zfs.

Disk management
Expand existing LUNs or add additional LUNs if you
need more space. Since Solaris 11.4 you can remove LUNs if you
want to shrink your pool.

Features
No need for filesystem checks, because of the copy-on-write
implementation. You can create snapshots and clones,
use encryption and compression. Transfer data to other
systems using send/receive or sharing.
Move the pools using export/import to other systems.

ZFS builds the base for the Solaris BootEnvironment (beadm)
where you are able to update to and boot from different Solaris 11
Updates.

ZFS is my preferred filesystem and volume manager, but
is everything perfect? No. You need to carefully configure
ZFS to avoid and work around fragmentation.


Oracle Database

You can run Oracle Database very well on ZFS and profit
from snapshots, cloning and other features. Especially
for larger databases (many TB) with lots of data changes
you should setup carefully.

Following a few Best Practices based on own experiences
and Recommendations by Oracle:

- data pool with log device / 8KB recordsize for data / logbias=latency
- redo pool with log device / 1MB recordsize / logbias=latency
- archive pool / 1MB recordsize

Add multiple LUNs for striping. Use SSDs for highest performance.
If you are using SAN increase zfs:zfs_vdev_max_pending and ssd:ssd_max_throttle to 20.
Limit the ZFS Cache (zfs:zfs_arc_max)
Make sure there is around 20% free space on the zpools.
Use a Server with 'enough' Memory.

After many years of using ZFS it always hurts, if I have
to use other more complicated filesystem ....
