Categories / Groups & Packages in RHEL

[jmgmad]

I´m using Red Hat Enterprise Linux (RHEL) version 5.

I´m SAP administration system, and I ´m stuck in prerequisite check, what I have to ensure, before installation of sap system, is check if the S.O. red hat have installed some things that are required... which are some package and groups/categories... I don´t have any experience in Linux and so I ask for help please how can I know, from Terminal command line which packages are installed in this S.O. and more I want to know what´s mean "Categories / Groups", because I read in a sap note that mandatory to have installed some categories / groups which are for instance:

- Servers/Printing Support
- Base System/Base
- Base System/X Window System
- Development/Legacy Software Development
- Development/Development Libraries (for Oracle databases)
- Development/Development Tools (for Oracle databases)


What´s this and how can I check if it all exist in my Linux?


Can you help me please!... Thank you.

If SAP has an rpm package, you can install it with the YUM package manager and it will deal with dependencies for you. So, use the command: yum install sap-package.rpm
where "sap-package.rpm" is the SAP rpm file, if it exists, to install SAP. Any dependencies should be resolved by YUM for you, installing what is needed.

As for checking if certain packages are installed on your system, use the command: yum list installed
That will list all installed packages on your system. You can direct the output of that to a file and then look for the packages you need there. If they aren't there, then you can install them. In any case, USE the YUM command to install packages in Red Hat systems, including Fedora, CentOS, RHEL, et al.

Hello Rubberman,

Thanks for your reply.

You´re right, but my doubts are not these, are not at that level, I already knew how can I check which packages are installed, I used this two commands:
yum list | grep installed
or
yum list | grep installed | more

Actually my problem is not that but to know which categories or groups were chosen during installation, this is very important because, for example, SAP recommends adding these two groups when used as oracle database:

- Development Libraries (for Oracle databases)
- Development Tools (for Oracle databases)

I don´t know because I didn´t installed the red hat system was someone else, this is in fact the main problem and so I don´t know what groups were chosen in the installation process and I need to know how to check which are installed because if this are not installed I have to install them because they are mandatory for install a sap system over this RHEL + Oracle DB 10.2g...

Do you understand what is, in fact, my main problem?


So can you help me...?!

Not sure I quite get yet what your real problem is - probably a language thing. Unfortunately, I don't speak/read Portugese, though I am fluent in Spanish. Anyway, from what you are saying, you are uncertain whether or not those Oracle components are installed. If Oracle Enterprise is already on the system, then run the Oracle installer to make sure those development tool components are also installed besides the standard database and such. Is that what you are having a problem with? Getting to and running the Oracle installer? Remember, Oracle has its own installer and does not go through the standard system package tools.

Hello Rubberman,

Ofcourse that I know there is a Oracle installer, and I have that DVD!

Even so, I have to make sure before installing the database that the operating system is in fact prepared to receive it (oracle). But I don´t know if this is really a problem for not being able to install the database. This may be just a matter of optimizing the system...!


But what I wiil do now is install the database and then see if there is any error with respect to this!


Thank you

Well, in your original posting, you mention the mandatory things you need installed on the system, to wit

- Servers/Printing Support
- Base System/Base
- Base System/X Window System
- Development/Legacy Software Development
- Development/Development Libraries (for Oracle databases)
- Development/Development Tools (for Oracle databases)

Ok. The first 3 items are likely installed on your system if you can boot, print, and get a GUI such as KDE or Gnome. The 4th item, Development/Legacy Software Development means (as far as I can tell) do you have the gnu compiler suite installed. If you can compile a c and c++ program, then the answer is yes. As for the last 2 items, those are Oracle-specific issues I think, and should be installable either via the standard Oracle installer UI, or otherwise. You will want the OCI (Oracle Call Interface) headers and libraries installed, as well as Embedded SQL preprocessor stuff, etc. As I recall, these are optional packages you can select to install from the Oracle Installer UI.
