clarify starting/stopping database ora<sid>, <sid>adm, sqlplus, startsap

I confess we have a great deal of uncertainty about the consequences of running the Oracle Database as the ora<sid> user vs. the <sid>adm user, and similarly using simple sqlplus as ora<sid> vs startsap/stopsap as <sid>adm .

What is the potential harm if any in choosing to start/stop the database as ora<sid> using sqlplus, and is there a compelling arguement for using the startsap/stopsap utilities, especially running these as <sid>adm vs. ora<sid> ?

Any input on best practice is greatly appreciated. !!

Thanks in advance

Dave Hays

    As long as you start/stop in the correct order I dont see any problem.

    by default, user [sid]adm is not part of "dba" group, so, it might not be able to shutdown Oracle.

    so, if you put user [sid]adm part of group dba, it does not matter.

      Hi David,

      This is purely on the discretion of the person who has installed orset up the SAP system.

      sidadm and orasid users belong to different groups and enjoy different privileges according to that. Once SAP is installed both the users have changes in the enviornment settings as per the user group. SO no harm in using either of the users if you can perform the task succesfluuy.

      For best practices, you can check the SAP installation document for more information.

    You said you have observed great deal of uncertainity about the consequences

    of running them with different id's ...can you please specify what are those

    uncertainities you have observed.regarding startup and stop there will no

    problem on behalf of which userid you have choosen.I agree <sid>adm n ora<sid>

    has differences...but not in case of basic start and stop.

    • Hi Dave,

      As you said --you mostly support database,I would

      suggest you to carry on with <sid>adm.This is my expereince ..i would like

      to share with you.

      with admin userid

      when working in SAP 4.7EE with Oracle 8i,I observed a thing that when I go for

      start>run>(type as)BRTOOLS ,I didnt get any specifications BUT WITH

      with <sid>adm

      If I give BRTOOLS--I used to get options whether

      to start/stop DB,


      Add a tablespace...etc

      After this experience I came to know the importance of <sid>adm userid.

      As you said you concentrate more to support try to work with <sid>adm.

      Hope this answer helps,
