how does lslpp == list software products???


Just getting started with AIX surely they could have thought of an acronym that is a bit more self explainatory than this:


lslpp Command

Purpose

Lists software products.

</moan>

thats my big gripe at the moment with AIX. the commands dont make sence. and why do they require so many switches to do the things that people use the most?

lslpp = “list licensed program products”

To me it makes sense, but then I have been working with AIX for 10 years. What command(s) do you believe require so many options?

Which version of the C compiler am I currently using ?
whant is my asynchronous I/0 driver ?
lslpp -l gives you the answer.

I have exactly the same problem with Linux. I know I need to use rpm in order to know if I correctly installed the kernel sources, but it's rpm -hUV or rpm --something ?
If you are familiar with AIX you find it easy and you feel Linux rather tough...

i made another post about producing a cdrom fs a couple of days ago. _that_ is a lot of commands.

I know, and can now appreciate a bit more after reading, that the smitty crcdrfs will do the same thing these days.

I just dont like feeling over whelmed.

Is there a lot of money in AIX? We have had really hard time finding an AIX person, so i decided to do it.

You will find the number of administrators for the commercial Unix variants (AIX, Solaris, HP-UX) is greater for Solaris and HP-UX than AIX, because Sun has the most machines installed worldwide. Solaris and HP-UX are more “Unix”-like and you will find similarities with BSD and/or Linux, unlike AIX.

IBM pSeries servers have more power than comparable Sun servers, but IBM has a larger price tag, too, which might be a reason there are not as many installed systems. However, when you get to large companies, like my previous company, which was a Fortune 400 company, they will have multiple vendors (they had AIX and Solaris) but will lean more toward one (they leaned toward AIX). It is even a more narrowly defined field for AIX if you include the SP2, which I have worked on for over 5 years. There are even fewer SP/PSSP administrators than AIX administrators.

The pay for an AIX administrator would be the same pay that a Solaris administrator makes, though I saw a survey once that had a Solaris admin making more than AIX (probably because there is more work in administering Solaris servers), but really it will be the same. Where you will make more with AIX is going the SP route, where there are fewer installed systems, but the complexity is greater and the systems cost a lot more. Also, the workload on SP systems are normally mission-critical and are not transparent to the company’s business, thus downtime equals large losses. One system at my former company (the Fortune 400 company) had losses of $1+ million per hour of downtime. For those types of systems companies will pay more for a knowledgeable and skilled administrator.

Bottom line – yes there are AIX admins who do make money, but they are more skilled (SP/Regattas, mission-critical, etc.) but they are fewer than Solaris/HP-UX and the money will be about the same (unless you go SP, etc.).

A way of managing anything up to several hundred servers from a single control workstation, using special software called PSSP which runs on top of AIX.

SP is IBM Scalable Power Parallel systems. I don’t believe they are making them anymore because of the pSeries “Regatta” partitioned systems. However, because of the cost that companies have spent on them, I am sure they are not just going to dump them to move to a Regatta, as long as they are getting use out of the nodes.

The SP consists of a frame that has up to 16 nodes inside, each of which runs its own AIX operating system. There are high, wide, and thin nodes which take up 4, 2, and 1 slot, meaning you can mix the type of nodes in a frame. The control workstation is used to manage the frames. There can be multiple frames and up to 256 nodes (I believe, I don’t think it is 512), but there can be more going through IBM and have them custom design it. There is also a high-speed switch used for interconnection.

There are also SP systems on the Top 500 Supercomputer list.

And nowardays CSM clusters are to be used for much the same purpose as pssp before. Even if all the functionallity arent there yet.
Personnaly I think it was good to leave "special" hardware as the SP-nodes/frames and go for a was to cluster the regular IBM hw. I do miss PSSP though.
