Hi all,
I have a strange situation here, I got a Linux OEL 7.7 machine where Oracle software was installed, but not the database.

I have no info on how it was installed. I have user oracle ( and root if needed ).

My ORACLE_BASE, ORACLE_HOME are:


[oracle@MY_ORACLE_MACHINE oracle]$ echo $ORACLE_BASE
/u01/app/oracle
[oracle@MY_ORACLE_MACHINE oracle]$ echo $ORACLE_HOME
/u01/app/oracle/product/12.1.0.2/dbhome

I do NOT have any instance running:


[oracle@MY_ORACLE_MACHINE oracle]$ ps -ef | grep pmon
oracle   14183 10193  0 18:46 pts/0    00:00:00 grep --color=auto pmon

I have file /u01/app/oracle/product/12.1.0.2/dbhome/dbs/initMYDB.ora that contains:




db_name='MYDB'
memory_target=5G
processes = 300
audit_file_dest='/u01/app/oracle/admin/MYDB/adump'
audit_trail ='db'
db_block_size=8192
db_domain=''
db_recovery_file_dest='/u01/app/oracle/fast_recovery_area'
db_recovery_file_dest_size=2G
diagnostic_dest='/u01/app/oracle/diag'
dispatchers='(PROTOCOL=TCP) (SERVICE=MYDBXDB)'
open_cursors=300
remote_login_passwordfile='EXCLUSIVE'
undo_tablespace='UNDOTBS'
# You may want to ensure that control files are created on separate physical
# devices
control_files = (ora_control1, ora_control2)
compatible ='11.2.0'

So I go ahead and make sure the paths "/u01/app/oracle/admin/MYDB/" , "/u01/app/oracle/admin/MYDB/adump" and "/u01/app/oracle/fast_recovery_area" exist:

[oracle@MY_ORACLE_MACHINE dbs]$ mkdir -p /u01/app/oracle/admin/MYDB/
[oracle@MY_ORACLE_MACHINE dbs]$ mkdir -p /u01/app/oracle/fast_recovery_area/MYDB
[oracle@MY_ORACLE_MACHINE dbs]$ mkdir -p /u01/app/oracle/admin/MYDB/adump
I also created a folder for my data files:

mkdir -p $ORACLE_BASE/ORADATA/MYDB


Now I want to create a database.

I decide that

- My log files will be stored in /u01/app/oracle/fast_recovery_area/MYDB
- My datafiles will be stored in /u01/app/oracle/ORADATA/MYDB

So I am starting the database in nomount with the new pfile:


[oracle@MY_ORACLE_MACHINE dbs]$ export ORACLE_SID=MYDB
[oracle@MY_ORACLE_MACHINE dbs]$ sqlplus / as sysdba

So now I want to create my controlfiles and database, so I go:


SQL> CREATE DATABASE MYDB
  2     USER SYS IDENTIFIED BY Newproj2020
  3     USER SYSTEM IDENTIFIED BY Newproj2020

           GROUP 2 ('/u01/app/oracle/fast_recovery_area/MYDB/redo02.log') SIZE 100M,
  5    6             GROUP 3 ('/u01/app/oracle/fast_recovery_area/MYDB/redo03.log') SIZE 100M
  7     MAXLOGFILES 5

 16     SYSAUX DATAFILE '/u01/app/oracle/ORADATA/MYDB/SYSAUX01.DBF' SIZE 100M REUSE
 17  AUTOEXTEND ON
 18  NEXT 10M MAXSIZE 200M
   DEFAULT TEMPORARY TABLESPACE tempts1
      TEMPFILE '/u01/app/oracle/ORADATA/MYDB/temp01.dbf'
      SIZE 20M REUSE
 19   20   21   22     UNDO TABLESPACE UNDOTBS
 23        DATAFILE '/u01/app/oracle/ORADATA/MYDB/undotbs01.dbf'
 24        SIZE 200M REUSE AUTOEXTEND ON NEXT 5120K MAXSIZE UNLIMITED;

Database created.

SQL>



I check that it is open:

SQL> select open_mode from v$database;

OPEN_MODE
--------------------
READ WRITE

SQL>

But when I try to query DBA tables - I get a strange error... and I have checked that I am user SYS:


SQL> select table_name from dba_tables;
select table_name from dba_tables
                       *
ERROR at line 1:
ORA-00942: table or view does not exist


SQL> show user
USER is "SYS"
SQL>

What am I missing, why do I have a problem accessing DBA views ?

Will appreciate some advice. Thanks very much in advance
Andrey

You have to run scripts to create them. Have you read the docs? You seem to be here,

That helped to solve the issue.

And yes, I've read some parts of it but I admit I got a little hasty and impatient about reading it all,
partially because I wasn't sure I can find a step by step explanation to the style of installation I did.

I promise to improve Smile

Great thanks for the help.
Have a nice day.

Andrey
