Checking the Hardware requirements for installing Oracle 11g R2 on AIX 7.1
Memory requirements: Oracle needs at least 4 GB of RAM, and yes we have 24 GB so we are good on that.
Swap requirements: For 4 GB to 8 GB Memory the swap requirement is 2 times the size of RAM, for 8 GB to 32 GB the requirement is 1.5 times the size of RAM, and if the Memory is more than 32 GB then the swap space required is 32 GB.
36GB.So let us see how this can be done on AIX 7.1 . There we go, I just added 3
Hardware mode: What next, ok we need to know what our hardware is in 32-bit or 64-bit mode.
/tmp size: Now what, yeah what is the disk space requirement. First off /tmp needs to be at least 1 GB. We are ok
with that.
Run Level: Oracle also needs the system run level to be 2. So, how do we find that in AIX
Now that we are done with checking to see if our system meets the hardware requirements for Oracle, let us go ahead and check to see
Service Pack: The OS level needs to be AIX 7.1 with SP 1 or above, with 64-bit kernel. What I currently have is the base AIX 7.1 without the Service Pack, so I downloaded SP2 from http://www-933.ibm.com/support/fixcentral/
After the installation of the Service Pack(SP2) the oslevel is as follows:
Additional filesets: Next we have to check if the following filesets are installed Hmmm, it looks like one guy is missing. Can we do without him, I don't know.
Ok, went on to install bos.adt.libm from the original AIX 7.1 base dvd.
Once the above is done, go and install SP1 or later service pack. In my case I installed SP2 which I had saved under /usr/sys/inst.images
AIX maintainance packages are available from the following web site:
http://www-933.ibm.com/support/fixcentral/
Kernel mode: Next find if the kernel mode is 64
Compiler: There are some compiler requirements for installing Oracle. I installed the The minimum recommended runtime environment:
IBM XL C/C++ for AIX, V10.1 Runtime Environment
http://www-01.ibm.com/support/docview.wss?rs=2239&uid=swg24019829
UDP and TCP Kernel Parameters:
Use NDD to ensure that the kernel TCP/IP ephemeral port range parameters are set to 9000-65500.
Let me check to see what my current values are:

Memory requirements: Oracle needs at least 4 GB of RAM, and yes we have 24 GB so we are good on that.
isvp17> lsattr -E -l sys0 -a realmem realmem 25165824 Amount of usable physical memory in Kbytes False
Swap requirements: For 4 GB to 8 GB Memory the swap requirement is 2 times the size of RAM, for 8 GB to 32 GB the requirement is 1.5 times the size of RAM, and if the Memory is more than 32 GB then the swap space required is 32 GB.
isvp17> lsps -a Page Space Physical Volume Volume Group Size %Used Active Auto Type Chksum hd6 hdisk0 rootvg 512MB 3 yes yes lv 0Ok, we not doing good in that front. We'll have to find a way to increase the size of swap from 512MB to
36GB.So let us see how this can be done on AIX 7.1 . There we go, I just added 3
isvp17> lsps -a Page Space Physical Volume Volume Group Size %Used Active Auto Type Chksum paging00 hdisk5 swap 36096MB 1 yes yes lv 0 hd6 hdisk0 rootvg 512MB 3 yes yes lv 0
Hardware mode: What next, ok we need to know what our hardware is in 32-bit or 64-bit mode.
isvp17> /usr/bin/getconf HARDWARE_BITMODE 64
/tmp size: Now what, yeah what is the disk space requirement. First off /tmp needs to be at least 1 GB. We are ok
with that.
isvp17> df -m /tmp Filesystem MB blocks Free %Used Iused %Iused Mounted on /dev/hd3 3584.00 3581.39 1% 41 1% /tmpSo what is the space required for the Oracle binaries, and it's datafiles? For Enterprise Edition 7.44 GB (just say 8 GB) is required, and for the data files require 1.55 GB ( you mean 2 GB).
Run Level: Oracle also needs the system run level to be 2. So, how do we find that in AIX

isvp17> /usr/sbin/no -o tcp_ephemeral_low=9000 -o tcp_ephemeral_high=65500 Setting tcp_ephemeral_low to 9000 Setting tcp_ephemeral_high to 65500 isvp17> /usr/sbin/no -o udp_ephemeral_low=9000 -o udp_ephemeral_high=65500 Setting udp_ephemeral_low to 9000 Setting udp_ephemeral_high to 65500 isvp17>The options you set with no must be done each time the system starts up. One way to do that is to edit /etc/rc.tcpip and insert your no commands just before the script starts running the server daemons.
Enable core file creation:

These values cannot exceed the "hard" limit value. To display and change the hard limits, you can run the ulimit commands using the additional -H command-line option.
