Step1: Cell patching in rolling mode
step2: Downtime patching for below:
First have IB Switches patching
then GI home patch
then ORACLE homes patching
then yum upgrade
then apply datapatch for all databases, if you face issue with automation script of oracle for CDB databases, so please ran datapatch manually on all databases.
To check the OS version and details
dcli -l root -g ~/dbs_group " cat /etc/redhat-release"
dcli -l root -g ~/dbs_group imageinfo | grep -i ' image version'
dcli -l root -g ~/dbs_group "ipmitool sunoem version"
dcli -l root -g ~/dbs_group "/opt/oracle.cellos/CheckHWnFWProfile -c strict"
dcli -l root -g ~/dbs_group "ipmitool sunoem cli 'show faulty'"
dcli -l root -g ~/ibswitch_lst "version |grep -i version"
dcli -l root -g ~/all_group 'for cable in `ls /sys/class/net/ |grep ^eth`; do printf "$cable: "; cat /sys/class/net/$cable/carrier ; done'
dcli -l root -g /root/dbs_group dbmcli -e list alerthistory where endTime=null and alertShortName=Hardware and alertType=stateful and severity=critical
dcli -l root -g ~/all_group "uptime"
dcli -l root -g ~/dbs_group "/u01/app/19.0.0.0/grid/bin/crsctl query crs softwareversion"
dcli -l root -g ~/dbs_group "/u01/app/19.0.0.0/grid/bin/crsctl query crs activeversion -f"
dcli -l root -g ~/dbs_group "/u01/app/19.0.0.0/grid/bin/crsctl query crs releasepatch"
dcli -l root -g ~/dbs_group "/u01/app/19.0.0.0/grid/bin/crsctl query crs releaseversion"
dcli -l oracle -g ~/dbs_group "/u01/app/19.0.0.0/grid/OPatch/opatch lspatches"
dcli -l oracle -g ~/dbs_group "/u01/app/oracle/product/12.1.0.2/DbHome_1/OPatch/opatch lspatches"
dcli -l oracle -g ~/dbs_group "/u01/app/oracle/product/12.2.0.1/dbhome_1/OPatch/opatch lspatches"
dcli -l oracle -g ~/dbs_group "/u01/app/oracle/product/19.0.0.0/dbhome_1/OPatch/opatch lspatches"
ssh hostname-ilom -->then press enter
ls -ltr /proc/meminfo | grep -i huge
sh hugepages.sh --> this is for hugepages suggestion --> This script will be provided by mosc doc 401749.1 where it is intended to compute the values for huge pages
dbmcl --> list alerthistory
