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

/dev/dsk/c1t0d0s3 --swap -no -

Method B

$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
