14 Vmware workstation add virtual disk

OCR 1G DATA 20G

First add the disk of the HIS1 node, and then add the existing disk to HIS2, and allocate the disk space in advance.

15 Select the disk channel:

Select 1:0 channel for Ocr and 1:1 channel for data.

16 modify the vmx file of HIS1 and HIS2 by adding the following:

Disk.locking= "FALSE"

Disk.EnableUUID= "TRUE"

DiskLib.dataCacheMaxSize= "0"

DiskLib.dataCacheMaxReadAheadSize= "0"

DiskLib.dataCacheMinReadAheadSize= "0"

DiskLib.dataCachePageSize= "4096"

DiskLib.maxUnsyncedWrites= "0"

Scsi1:0.sharedBus= "VIRTUAL"

Scsi1:0.virtualDev= "lsilogic"

Scsi1:0.deviceType= "disk"

Scsi1:1.sharedBus= "VIRTUAL"

Scsi1:1.deviceType= "disk"

Scsi1:2.sharedBus= "VIRTUAL"

Scsi1:2.virtualDev= "lsilogic"

Scsi1:2.deviceType= "disk"

17 initialize the newly added disk

Restart the HIS2 node after HIS1 initialization, and there is no need to initialize the disk on the HIS2.

Initialize the operation:

18 disk configuration

Test environment cleans up previous data

Dd if=/dev/zero of=/dev/sdb1

Dd if=/dev/zero of=/dev/sdc1

Dd if=/dev/zero of=/dev/sdd1

a. Get the uuid that needs to be bound as an asm disk, and check whether the id on the two servers is consistent

Obtain disk id under multi-path

/ usr/lib/udev/scsi_id-whitelisted-replace-whitespace-device=/dev/emcpowerb

/ usr/lib/udev/scsi_id-whitelisted-replace-whitespace-device=/dev/emcpowerc

/ usr/lib/udev/scsi_id-whitelisted-replace-whitespace-device=/dev/emcpowerd

b. Bind and write udev.rules files

Vi / etc/udev/rules.d/99-oracle-asmdevices.rules

General disk configuration:

KERNEL== "sd?", SUBSYSTEM== "block", PROGRAM== "/ usr/lib/udev/scsi_id-whitelisted-replace-whitespace-device=/dev/$name", RESULT== "36006016002e045002988e0598f38600b", SYMLINK+= "asm/asm-ocr", OWNER= "grid", GROUP= "asmadmin", MODE= "0660"

KERNEL== "sd?", SUBSYSTEM== "block", PROGRAM== "/ usr/lib/udev/scsi_id-whitelisted-replace-whitespace-device=/dev/$name", RESULT== "36006016002e045008387e059821bbb14", SYMLINK+= "asm/asm-fra", OWNER= "grid", GROUP= "asmadmin", MODE= "0660"

EMC multipath disk configuration:

KERNEL== "emcpower?", SUBSYSTEM== "block", PROGRAM== "/ usr/lib/udev/scsi_id-whitelisted-replace-whitespace-device=/dev/$name", RESULT== "36006016002e045002988e0598f38600b", SYMLINK+= "asm-ocr", OWNER= "grid", GROUP= "asmadmin", MODE= "0660"

c. Check whether the binding is successful

Udevadm test / sys/block/emcpowerb

Udevadm info-query=all-path=/sys/block/emcpowerb

Udevadm info-query=all-name=asm-ocr

Udevadm test / sys/block/emcpowerc

Udevadm info-query=all-path=/sys/block/emcpowerc

Udevadm info-query=all-name=asm-fra

Udevadm test / sys/block/emcpowerd

Udevadm info-query=all-path=/sys/block/emcpowerd

Udevadm info-query=all-name=asm-data

d. Restart the udev service

Udevadm control-reload-rules

e. Check device binding

Ll / dev/asm*

f. Modify asm disk permissions

Chown-h grid:asmadmin / dev/asm/*

Fourth, install Oracle CRS

1 use grid users to execute the installation package

. / runInstaller

2 skip software updates

3 install and configure cluster grid

4 language selection

5 Cluster node and ssh configuration-Select setup

6 complete the installation

7 execute the relevant script

Configure the ohas service:

Before executing the root.sh script, add the ohas service:

A) cd / etc/systemd/system/

Touch ohas.service

B) Edit the file ohas.service to add the following text

[Unit]

Description=Oracle High Availability Services

After=syslog.target

[Service]

ExecStart=/etc/init.d/init.ohasd run > / dev/null 2 > & 1 Type=simple

Restart=always

[Install]

WantedBy=multi-user.target

C) run the following command (as root):

Systemctl daemon-reload

Systemctl enable ohas.service

Systemctl start ohas.service

D) run root.sh

After executing the root.sh script, start the ohas service when the following prompt appears:

:

Installing Trace File Analyzer

OLR initialization-successful

Start the ohas service:

Query if the installer has created the / etc/init.d/init.ohasd file, and if so, run the ohas service:

Systemctl start ohas.service

Node 2 executes root.sh

When Adding Clusterware entries to inittab is displayed

Start the ohas service:

Query if the installer has created the / etc/init.d/init.ohasd file, and if so, run the ohas service:

Systemctl start ohas.service

8 check the service status after completion

5. Install database software

1 create a related asm disk group

2 Oracle users run. runInstall

3 choose to install only database software

4 choose to install the instance on both servers

5 configure oracle user equivalence

6 Select installation language

7 install Enterprise Edition

8 ignore partial check error

9 an error was reported during installation

To fix this error edit $ORACLE_HOME/sysman/lib/ins_emagent.mk, search for the line

$(MK_EMAGENT_NMECTL)

And replace the line with

$(MK_EMAGENT_NMECTL)-lnnz11

Then click "Retry" button

Create a database instance

1 Oracle user executes dbca to create database instance

2 enter the name of the created instance

3 configure Em

4 configure user password

5 Select oms and data file storage disk group

6 configure archiving and flashback area

7 memory configuration

8 error report, Tip not / dev/shm space is too small

Execute on his and his2

Sudo mount-o size=3168M-o remount / dev/shm

9 concurrency configuration

10 configure character set

11 start installing the database

12 complete the database installation

VII. Inspection of the installation environment

1 check the startup of the cluster service

2 check the monitoring status

3 use different ip to connect to the database, verify that the login is normal, and the installation is over.
