Section: A Check All Pre-request for Clusterware installation
Step 1: Check Hardware Requirement
RAM should be at least 1GB
How to Check? Use following command: $ /usr/sbin/prtconf | grep “Memory size”
Swap Size: If RAM more then 2GB then Swap should be equal of RAM and If RAM between 1 to 2 gb then Swap should be 1.5 times of RAM
How to Check? Use following command: # /usr/sbin/swap –s or log in as a “ROOT” user and execute following command: $swap –s or swap –l
How to ADD Swap Space?
Method A
-
create a file system with desire space (eg: /c0d2s0)
-
Add the bellow mention line in /etc/vfstab file
/dev/dsk/c1t0d0s3 –swap -no –
Method B
-
create a file system with desire space (eg: /c0d2s0)
-
Use the swap -a command to add an additional swap area.
$swap -a /dev/dsk/c1t0d0s3
Method C
Swap files can be used when you need to add swap space and do not have a free partition to use. To add a swap file, complete the following steps:
1. Create a 1G swap file named swapfile in the partition that have enough free space, for example /export/data directory.
# mkfile 1000m /export/data/swapfile
2. Add the swap file to the system’s swap space.
# swap -a /export/data/swapfile
3. List the details of the modified system swap space with swap -l
4. List a summary of the modified system swap space with swap -s
5. To use a swap file when the system is subsequently rebooted, add an entry for the swap file in the /etc/vfstab file.
/export/data/swapfile –swap -no –
Temp Space: Minimum 400 MB of disk space required in the /tmp directory
How to check? Use following command: # df -k /tmp
Check system architecture
How to Check? Use following command: # /bin/isainfo –kv
Result should be:
64-bit SPARC installation:
64-bit sparcv9 kernel modules
32-bit x86 installation:
32-bit i386 kernel modules
64-bit x86 installation:
64-bit amd64 kernel modules
Step 2: Check Required Packages
How to check? Use following command:
# pkginfo -i SUNWarc SUNWbtool SUNWhea SUNWlibm SUNWlibms SUNWsprot SUNWsprox SUNWtoo SUNWi1of SUNWi1cs SUNWi15cs SUNWxwfnt
If a package that is required for your system architecture is not installed, then install it.
Step 3: Check Patches
Refer to your operating system or software documentation for information about installing packages
