Over time after many online memory changes, the memory may become
fragmented like this example. The small blocks prevent the system
from allocating large pages which causes degraded performance.
The fragments typically arise when you reduce memory
while the domain is running. It is recommended to reduce
memory while the guest domain is down and use start-reconf
for the control domain.

Oracle changes Solaris 11.4 SRU delivery
In the past Oracle provided Solaris SRUs (Support Repository Updates)
each month. This does change now. The types of SRUs are reduced
from 3 types to 2 types. Instead of 12 SRUs per year we will see 8 SRUs
per year.
a) Feature SRU (NEW)
This will be available early in the months
March, June, September, December
Around 6 weeks after the CPUs.
This SRU includes new features, tools, packages, version updates
and removal of old, outdated/insecure software.
I would recommend to install this SRU on test systems to verify
application compatibility and identify required configuration changes.
b) CPU (Critical Patch Updates)
No changes here.
Available January, April, July, October
The release dates are predefined and are published on
https://www.oracle.com/security-alerts/#CriticalPatchUpdates
This SRU includes critical fixes and security updates.
Most of our enterprise customers update to this SRU.
For critical issues Oracle will release individual
IDRs (Interim Diagnostic or Relief).

The Next Oracle Solaris 11.4.90 CBE is available for Developers
CBE is the Common Build Environment
The first release 11.4.42 was made available by Oracle 03/2022.
Last year 05/2025 the version 11.4.81 was published.
And now 03/2026 11.4.90 is already available.
This release can be used by Developers to develop, test and demonstrate
their software for free. It includes current compilers and tools.

https://www.oracle.com/solaris/solaris11/downloads/solaris-downloads.html
This is great news and confirms Oracle continues investing into Oracle Solaris.

The State of Oracle Solaris - Jan 2026
Oracle Solaris is not much in the press anymore, but used
for critical systems around the world.
Solaris 11.4 was launched in 2018. Oracle provides updates/patches
every month. Every quarter (Feb,May,Aug,Nov) the update includes new features.
Oracle will provide this monthly updates till at least November 2037.
Documented in:
http://www.oracle.com/us/support/library/lifetime-support-hardware-301321.pdf
Oracle is working to make sure Solaris will run properly after 2037 for example
with changes in SRU72 delivered in August 2024. It would be no surprise
if the updates will continue after November 2037.
https://blogs.oracle.com/solaris/announcing-oracle-solaris-114-sru72
For developers a pretty current version (CBE) is available
for free to develop and test software.
Solaris CBE Download:
https://www.oracle.com/solaris/solaris11/downloads/solaris-downloads.html
Oracle even provides patches for the older releases Solaris 10
and Solaris 11.3. The last patches are expected by January 2027.
We highly recommend to migrate to Solaris 11.4 and we are
happy to support you with our very experiences engineers.
Oracle's Management and Monitoring tools (OpsCenter and VM Manager for SPARC)
reached End-Of-Life. No patches are provided anymore.
We at JomaSoft continue to enhance our VDCF management and monitoring tool
for Oracle Solaris and Linux
https://www.jomasoft.ch/vdcf/
If you don't have a SPARC server yourself, maybe the JomaSoft
SPARC cloud could be helpful for you.

system-repository SMF access_log cleanup
The system-repository SMF delivers IPS packages to zones.
This SMF produces an access_log file which is not rotated
by default. If you run many zones this logfile grows
to multiple 100 MB. On a customer system with more
than 20 zones this file was over 3 GB in size.
This is a sample on one of our test systems
# ls -lh /var/log/pkg/sysrepo/access_log
-rw-r--r-- 1 pkg5srv bin 148M Jan 8 10:52 /var/log/pkg/sysrepo/access_log
You can manually rotate and compress this logfile using
the following command
# time logadm -c -z 0 /var/log/pkg/sysrepo/access_log
real 0m4.989s
user 0m4.164s
sys 0m0.815s
# ls -lh /var/log/pkg/sysrepo/access_log*

Cleanup Oracle Solaris Audit files
Auditing is enabled by default on Solaris 11.4 and records security-related system events,
like logins, reboots, etc.
The audit files are stored in /var/share/audit.
Overtime this files use quiet some disk space
# cd /var/share/audit/
# du -sh
18.3G .
For later analysis a backup of this files is recommended.
Maybe you have a central archive or security tools for this.
On the Solaris server there is no automatically cleanup
of this files active. This should be done manually from time to time.
For example to delete files older than 3 years.
find /var/share/audit -mtime +1095 -exec rm {} \;
If you are using JomaSoft VDCF you can execute this on all your Solaris 11 Nodes
# su
Password:
# echo "# cleanup audit files older than 3 years" >/var/opt/jomasoft/vdcf/config/script/cleanup_audit
# echo "find /var/share/audit -mtime +1095 -exec rm {} \;" >>/var/opt/jomasoft/vdcf/config/script/cleanup_audit

How to send files to Oracle Support SR using ASR Manager
Most of the time it is required to attach additional files to Oracle Support Cases,
for example ILOM/XSCF snapshots or Logfiles.
If you use the ASR Manager on Solaris it is very easy to attach
additional files. It includes a transport tool. No need to copy files to
your local machine and to upload using a Browser.
Check if you use the ASR Manager
# svcs |grep asrm
online 2024-05-08T17:29:45 svc:/application/management/asrm:default
You can just copy your files into this directory
/var/opt/asrmanager/sftransport/transfer/
The files need to start with your SR-Number, for example
3-31234567890.mylogfile
The files are transported to Oracle Support and attached
to your SR every 10 minutes.
You can check the state using
/opt/asrmanager/bin/sftransport info
