hi,
regarding Application SW, (Oracle,CAD Product,ecc) you must
read SW producer requirements.
In general the following commands give you an idea of
level and missing paches:
instfix -i | grep "AIX"
using first you see which is maximum ML applied; if
it is listed as
Not all filesets for 4330-09_AIX_ML were found.
use
instfix -i -k 4330-09_AIX_ML -c | grep ":-:"
The command
oslevel -r
give the maximum complete ML.
In AIX, pacthes are called ptf,apar,fix, depending from the moment: apar is the opend problem, the fix is the solution.
A Maintenance Level is seen as a fix and inside it has
a list of levels of fileset that belong to it.
When you do
instfix -i -k 4330-09_AIX_ML -c
the command checks lpp installed VS its list and
outs a full list with a sign + - = each fileset.
Grepping ":-:" you look for those have a lower level than requested.
The limit and the power of AIX vs Windows, is that you can
install only IBM-known devices and IBM knows its device-driver and put all-them on AIX CD . In the M.L. you find
the same lpp with a version higer:
bos.adt.debug 4.3.3.80 versus 4.3.3.0 in CD of AIX.
It is not completely true: if you have a AIX 4.3.3 very new,
you can find inside it, an already pacthed (4.3.3.56) lpp .
See in the CD (at the bottom) or in its box (in the back), a label as LCD4-0289-xx : xx may be 01 for 3-4 years old
CDs, 09-10 for recent ones.
