need best practice for Service Guard Implemetation

[installation_1]

Hi,

i am going to implement The Service guard on 11.31 for Oracle database and finacle application, please can any body provide me the best practice to implement this.

it is like database will run on one server and finacle will run on second server where as database will be passive on the server on which finacle will run and finacle will passive on the server on which database will run. please suggest me a best practice.

Hi,

You need to create Active -Active 2 node cluster. Both nodes should have identical hardware resources,and should have Redundant
LAN cards, redundant FC cards. and same level of patchsets on both the nodes.

A.11.19 is the latest Serviceguard version, along with use ECM toolkit for automatic startup and shutdown of
Database and applications.

Please go through below docs and let me know if any help reqd.

Hi,

Following would be the steps to implement SG as per your requirements.

1) Connect the power, network (private and public), fibre connections to the server (remember N+1 and no Single Point Of Failures)

2) Install the Serviceguard software and patches on both the nodes and reboot

3) Tune your kernel parameters required for Oracle database/application

4) Create Volume groups, logical vol, and FS for Oracle/application binaries and data

5) Install and configure Oracle on one mode in the Share disks

6) Run cmquerycl command and create the cluster ascii file

# cd /etc/cmcluster/
# cmquerycl -v -C cluster.conf -n node1 -n node2

Note: node1/2 would be your hostnames of servers.

7) Edit the cluster.conf and modify the cluster name at per your requirements.

8) create package directory ,create package conf and package script

# cd /etc/cmcluster
# mkdir oraclepkg
# cd oraclepkg
# cmmakepkg -p oraclepkg.conf
# cmmakepkg -s oraclepkg.cntl

9)# vi oraclepkg.conf


10) shutdown oracle, unmount filesystens, Deactivate all the volume groups and install the cluster ID

# vgchange -c y /dev/vgname

11) Edit package control script to include the package IP address, Package name, node names, volume group names, LV information

# vi /etc/cmcluster/oraclepkg/oraclepkg.cntl

12) Distribute the package directory to the other node

13) Check and apply the cluster/package conf

# cmcheckconf -v -C cluster.conf -P oraclepkg.conf
# cmapplyconf -v -C cluster.conf -P oraclepkg.conf

14) edit /etc/lvmrc and set AUTO_VG_ACTIVATE=0.

These are the high level steps for implementation, for detail please use the following docs.
