Install Oracle software

This page describes how to install Oracle software.

To install Oracle software, complete the following tasks:

  1. Install Oracle Grid Infrastructure.
  2. Install Oracle Database 26ai.

Install Oracle Grid Infrastructure

Install the Oracle Grid Infrastructure GoldImage on each database host to enable Oracle Restart and ASM. Both hosts require their own Grid home, ASM instance, and disk groups.

Oracle Data Guard replicates data over Oracle Net, not over shared storage.

Perform the following steps on oracdb1, and then on oracdb2.

  1. Stage the Oracle GoldImages, Release Update, and OPatch binaries on /u01/stage.

    sudo chown oracle:oinstall /u01/stage && sudo chmod 775 /u01/stage

  2. Extract the Grid GoldImage in the target Grid home. The 26ai Grid GoldImage installs by extracting in the target Grid home:

    sudo -u grid bash -c '
cd /u01/app/26ai/grid
unzip -q /u01/stage/LINUX.X64_<RELEASE>_grid_home.zip
'
sudo chown -R grid:oinstall /u01/app/26ai/grid

    If the Grid GoldImage is older than the target Release Update, patch the Grid home during setup using the gridSetup.sh -applyRU flow, or use a GoldImage with the Release Update bundled. Keep Grid and Database homes at the same intended patch level.

  3. Build the gridSetup response file /tmp/grid.rsp on each host. Replace the hostname and use strong passwords.

    HOST=$(hostname -s)
sudo -u grid bash -c "cat > /tmp/grid.rsp <<RSP
oracle.install.responseFileVersion=/oracle/install/rspfmt_crsinstall_response_schema_v23.0.0
INVENTORY_LOCATION=/u01/app/oraInventory
installOption=HA_CONFIG
ORACLE_BASE=/u01/app/grid
clusterUsage=GENERAL_PURPOSE
OSDBA=asmdba
OSOPER=asmoper
OSASM=asmadmin
storageOption=FLEX_ASM_STORAGE
sysasmPassword=WelcomeOracle1!
asmsnmpPassword=WelcomeOracle1!
diskGroupName=DATA
redundancy=EXTERNAL
auSize=4
diskString=/dev/mapper/ora_${HOST}_*p*
diskList=/dev/mapper/ora_${HOST}_data_01p1,/dev/mapper/ora_${HOST}_data_02p1
managementOption=NONE
RSP"
sudo -u grid chmod 600 /tmp/grid.rsp

  4. Run gridSetup.sh in silent mode to copy the binaries and stage the configuration.

    sudo -u grid bash -c '
export ORACLE_HOME=/u01/app/26ai/grid
export ORACLE_BASE=/u01/app/grid
cd /u01/app/26ai/grid
./gridSetup.sh -silent -responseFile /tmp/grid.rsp -ignorePrereqFailure
'

    Expected output is Successfully Setup Software with warning(s) and exit code 6 (warnings) or 0.

  5. Run orainstRoot.sh and root.sh as root. The root.sh script creates the crsctl, srvctl, and asmcmd wrappers and brings up OHAS.

    sudo /u01/app/oraInventory/orainstRoot.sh
sudo /u01/app/26ai/grid/root.sh

  6. Run gridSetup.sh -executeConfigTools to run the configuration assistants (NETCA, ASMCA, CVU) against the response file. This creates the ASM instance and the +DATA disk group.

    sudo -u grid bash -c '
export ORACLE_HOME=/u01/app/26ai/grid
export ORACLE_BASE=/u01/app/grid
cd /u01/app/26ai/grid
./gridSetup.sh -silent -executeConfigTools -responseFile /tmp/grid.rsp
'

    Expected output is Successfully Configured Software.

  7. Create the +RECO and +FRA disk groups using asmca. The single-shot install only creates +DATA. Create the other two throughasmca`.

    HOST=$(hostname -s)
sudo -u grid bash -c "
export ORACLE_HOME=/u01/app/26ai/grid
export ORACLE_SID=+ASM
\$ORACLE_HOME/bin/asmca -silent -createDiskGroup \
  -diskGroupName RECO \
  -disk /dev/mapper/ora_${HOST}_arch_01p1 \
  -redundancy EXTERNAL -au_size 4
\$ORACLE_HOME/bin/asmca -silent -createDiskGroup \
  -diskGroupName FRA \
  -disk /dev/mapper/ora_${HOST}_fra_01p1 \
  -redundancy EXTERNAL -au_size 4
"

  8. Verify the ASM disk groups and Oracle Restart resource status.

    sudo -u grid ORACLE_HOME=/u01/app/26ai/grid ORACLE_SID=+ASM \
  /u01/app/26ai/grid/bin/sqlplus -s / as sysasm <<'SQL'
SELECT name, total_mb, free_mb, state FROM v$asm_diskgroup ORDER BY name;
SQL
sudo /u01/app/26ai/grid/bin/crsctl stat res -t
# Expected ONLINE: `ora.DATA.dg`, `ora.RECO.dg`, `ora.FRA.dg`, `ora.LISTENER.lsnr`, `ora.asm`, `ora.cssd`, `ora.evmd`.

  9. Repeat steps 1 to 8 on oracdb2.

    Use the same ASM disk group names. Oracle Data Guard replicates over Oracle Net, not storage.

Install Oracle Database 26ai

Install the Oracle Database 26ai software home on each database host using a silent, software-only installation with the latest Release Update applied.

Perform all steps on oracdb1, and then on oracdb2.

  1. Extract the Database home, the latest OPatch, and the RU patch into their respective directories. Refer to the Oracle documentation for RU directory layout and the -applyRU path.

    sudo su - oracle
cd /u01/app/oracle/product/26ai/db_1
unzip -q /u01/stage/LINUX.X64_<RELEASE>_db_home.zip
rm -rf OPatch
unzip -q /u01/stage/p6880880_<base>_Linux-x86-64.zip                    # latest OPatch
unzip -q /u01/stage/p<RU_PATCH>_<base>_Linux-x86-64.zip -d /u01/stage   # latest 26ai RU

  2. Write the install response file and run the silent software-only installation with the RU applied. 

    sudo -u oracle tee /u01/stage/dbinstall.rsp >/dev/null <<'EOF'
oracle.install.option=INSTALL_DB_SWONLY
UNIX_GROUP_NAME=oinstall
INVENTORY_LOCATION=/u01/app/oraInventory
ORACLE_HOME=/u01/app/oracle/product/26ai/db_1
ORACLE_BASE=/u01/app/oracle
oracle.install.db.InstallEdition=EE
oracle.install.db.OSDBA_GROUP=dba
oracle.install.db.OSOPER_GROUP=oper
oracle.install.db.OSBACKUPDBA_GROUP=backupdba
oracle.install.db.OSDGDBA_GROUP=dgdba
oracle.install.db.OSKMDBA_GROUP=kmdba
oracle.install.db.OSRACDBA_GROUP=racdba
oracle.install.db.rootconfig.executeRootScript=false
EOF

  3. Run Oracle Database Installer.

    sudo -u oracle bash -c '
export CV_ASSUME_DISTID=OEL10    # OEL9 / OEL8.10 if cluvfy requires it
cd /u01/app/oracle/product/26ai/db_1
./runInstaller -applyRU /u01/stage/<RU_PATCH> -applyOneOffs /u01/stage/39292021 \
  -silent -ignorePrereqFailure -responseFile /u01/stage/dbinstall.rsp
'

  4. As root user, run the post-install root script.

    sudo /u01/app/oracle/product/26ai/db_1/root.sh

  5. Set the Oracle environment on each database host. Use ORACLE_SID=orcl on oracdb1 and ORACLE_SID=orcls on oracdb2.

    sudo -u oracle tee -a /home/oracle/.bash_profile >/dev/null <<'EOF'
export ORACLE_HOME=/u01/app/oracle/product/26ai/db_1
export ORACLE_SID=orcl                         # use 'orcls' on oracdb2
export GRID_HOME=/u01/app/26ai/grid
export PATH=$ORACLE_HOME/bin:$GRID_HOME/bin:$PATH
export TNS_ADMIN=$ORACLE_HOME/network/admin
EOF
