![]() | Caution - Do not perform this procedure without Oracle Support approval. Changing properties or disabling ssctuner features can have unpredictable consequences. |
Changing certain ssctuner properties such as EMAIL_ADDRESS and disk or memory usage warning levels might be advantageous in some environments.
# svccfg -s ssctuner listprop 'ssctuner_vars/*' ssctuner_vars/CRIT_THREADS_FIX boolean true ssctuner_vars/CRIT_THREADS_NONEXA boolean false ssctuner_vars/DISK_SPACE_CHECK boolean true ssctuner_vars/DISK_USAGE_CRIT integer 90 ssctuner_vars/DISK_USAGE_WARN integer 85 ssctuner_vars/DISM_CHECK boolean true ssctuner_vars/EMAIL_ADDRESS astring root@localhost ssctuner_vars/EMAIL_MESSAGES boolean true ssctuner_vars/FORCELOAD_VDC boolean false ssctuner_vars/INTRD_DISABLE boolean true ssctuner_vars/ISCSI_TUNE boolean true ssctuner_vars/MAJOR_INTERVAL integer 120 ssctuner_vars/MEM_USAGE_CRIT integer 97 ssctuner_vars/MEM_USAGE_WARN integer 94 ssctuner_vars/MINOR_INTERVAL integer 2 ssctuner_vars/NDD_TUNE boolean true ssctuner_vars/NFS_CHECK boolean true ssctuner_vars/NFS_EXCLUDE astring ssctuner_vars/NFS_INCLUDE astring ssctuner_vars/NTPCONF_TUNE boolean true ssctuner_vars/POWERADM_DISABLE boolean true ssctuner_vars/SDCONF_TUNE boolean true ssctuner_vars/SERD_THRESHOLD_TUNE boolean true ssctuner_vars/SSDCONF_TUNE boolean true ssctuner_vars/SYSLOG_DUP_SUPPRESS_HOURS integer 8 ssctuner_vars/SYSTEM_TUNE boolean true ssctuner_vars/ZPOOL_FIX boolean true ssctuner_vars/ZPOOL_NAME_CUST astring
These are examples of properties you might need to change:
Configure the system so that critical messages are sent to your email address.
~# svccfg -s ssctuner setprop ssctuner_vars/EMAIL_ADDRESS="my_name@mycorp.com"
Change the disk (/ and zone roots) usage warning level to 80%.
~# svccfg -s ssctuner setprop ssctuner_vars/DISK_USAGE_WARN=80
Enable thread priority changing for non-exa Oracle DB domains:.
~# svccfg -s ssctuner setprop ssctuner_vars/CRIT_THREADS_NONEXA=true
Enable zpool check and repair of vdisk zpools that are not generated by the SuperCluster installer.
~# svccfg -s ssctuner setprop ssctuner_vars/ZPOOL_NAME_CUST=my_vdisk_pool
Exclude NFS mounts from warning mechanisms.
~# svccfg -s ssctuner setprop ssctuner_vars/NFS_EXCLUDE='mount_name_or_device'
Include NFS mounts in warning mechanism (overrides exclude).
~# svccfg -s ssctuner setprop ssctuner_vars/NFS_INCLUDE='mount_name_or_device'
Disable all NFS mount warnings (not recommended).
~# svccfg -s ssctuner setprop ssctuner_vars/NFS_CHECK=false
The NFS_EXCLUDE, NFS_INCLUDE and ZPOOL_NAME_CUST properties must be simple strings but you can use simple regular expressions.
If you need the flexibility of regular expressions, be extremely careful to double quote the expressions. Also verify that the ssctuner service comes back after restarting and no errors are in the SMF log file.
# svcadm restart ssctuner
If you changed a property using an incorrect syntax, the service does not come back. If this happens, identify the offending property that you must fix:
# grep -i parameter /var/svc/log/site-application-sysadmin-ssctuner:default.log
After making any corrections or changes, repeat Step 3.
