Is it right to connect DB using SVRMGR. (I am a novice...) please HELP

Question

Hi every one.
My problem is combination of Oracle and SAP 4.6D.
After installing SAP i tried to make a client copy as i could not work on the '000 client. While doing client copy i get error message asking me extend Tablespace PSAPPOOLD.
I was asked by my friends to long on to DB and then type sysdba at cmd prompt and select option c (system administration).
I did the following steps, using SVRMGR i made "connect internal" then i logged on saying connect system/manager (as user name and password).
then i entered sapdba .....
By doing this nothing happened.
My Oracle is 8.0.5, the only thing i know to reach command prompt is SVRMGR although there is DBA studio under windows nt but i dont know how to use it much.
Please tell me how to connect to DB and how to get SAPDBA. (Please consider helping me keeping in view i am a biggenner and a novice).

For extending Tablespace PSAPPOOLD. You can follow the below steps.
c:\> set oracle_sid=<your_oracle_sid>
c:\> svrmgrl
SVRMGR>connect internal/<pwd>
You can resize the tablespace by two ways. Before that makesure you have suffice space on file system.
1. Increase the size of the existing datafile
2. Add new datafile to the tablespace
1. Increase the size of the existing datafile
SVRMGR> select file_name,bytes,maxbytes,autoextensible from dba_data_files where tablespace_name='PSAPPOOLD';
If the datefile is in autoextend mode then issue the following
SVRMGR> alter database datafile '<obsolute file_name from the above query>'
autoextend on maxsize <size>m;
If the datefile is NOT in autoextend mode then issue the following
SVRMGR> alter database datafile '<obsolute file_name from the above query>'
resize <size>m;
2. Add new datafile to the tablespace
SVRMGR> alter tablespace PSAPPOOLD add datafile '<obsolute new file_name >'
size <size>m;
