SIDADM rights on Linux

[Former Member]

Hi Girls and Guys,

I was wondering why we have to execute the change to SIDADM on linux always with "su - SIDADM" ?

What rights and what profile parameters are loaded when changing to SIDADM?

I know the bellow information's. But what is exactly happening when executing su - SIDADM?

DESCRIPTION

       Change the effective user id and group id to that of USER.

       -, -l, --login

              make the shell a login shell

       -c, --commmand=COMMAND

              pass a single COMMAND to the shell with -c and start a new session for it

       -C, --session-command=COMMAND

              pass a single COMMAND to the shell with -c and do not create a new session

       -f, --fast

              pass -f to the shell (for csh or tcsh)

       -m, --preserve-environment

              do not reset environment variables

       -p     same as -m

       -s, --shell=SHELL

              run SHELL if /etc/shells allows it

       --help display this help and exit

       --version

              output version information and exit

       A mere - implies -l.   If USER not given, assume root.

If you have any idea on what is loaded exactly let me know

Kind Regards

Andrei

Hi Andrei,

why we have to execute the change to SIDADM on linux always with "su - SIDADM" ?

IT is not required always. We normally do su - sidadm , becoz we login with our own id and then we perform switch user to sidadm or orasid

You can always make a direct login with sidadm user if you have the password.

When you login all the environment variables for this user gets loaded and shell prompt is set based on value in profile.

Hi Kori,

Thank you for the answer but if I log-in with the root and then make an "su SIDADM"  and try to execute R3trans -d it does not work. It gibes the bellow error. So what is exactly loaded when executing su - sidadm ?

serverSID:~ # su SIDadm

serverSID:t30adm 51> R3trans -d

This is R3trans version 6.24 (release 741 - 27.03.14 - 20:14:03 ).

unicode enabled version 2EETW152 Cannot open file "trans.log". : Permission denied

R3trans finished (0012).

Hi Andrei,

Looks like environment is not set correct for sidadm user.

please share output of command env after you login with sidadm.

Also share output of command ls -ltr under /home/t30adm.

Hi Andrei,

when you do "su sidadm", you basically become sidadm but without sidadm's environment, and without changing to sidadm's home directory. You stay in root's home directory where sidadm has no write permisssions - that's why you get a "permission denied" error.

When you do "su - sidadm", the login process looks up sidadm's home directory and shell in /etc/passwd. Usually this is /home/sidadm and C shell (csh). The C shell initialization files are .login and .cshrc under /home/sidadm. These files load other environment files such as .sapenv.csh and .dbenv.csh. You can see these "hidden" files with "ls -la /home/sidadm".
