Dear Experts,
I am now performing a test unicode conversion in a Sandbox system. This is ERP 6.0 EHP 6 on oracle 12c and Solaris.
I don't have a second test system for the target DB, so I successfully did the export and then I deleted the source system, in order
to use it for the import. When uninstalling the source system, I told SWPM to not touch the DB, as I wanted to leave the binaries
and not go through the hassle of reinstalling oracle. Then I have deleted all the data files, control files, online and offline redolog files,
just as it is being done for a refresh.
Unfortunately, this is NOT enough, as SWPM tells me: SAPinst has detected an existing DB and suggests me an MCOD installation:
At that point I selected to drop the old DB and I went on. BUT several screens later, it is proposing me code page 1100 and when
I type 4103 there, it's saying, that 4103 is not possible for non-unicode systems !!!
In answer to this, I have restored the controlfiles, I have started the DB in mount mode and I have dropped the DB:
$ sqlplus / as sysdba
SQL*Plus: Release 12.1.0.2.0 Production on Tue Jul 28 12:05:11 2015

Connected to:
Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production
With the Partitioning, OLAP, Advanced Analytics and Real Application Testing options
SQL> select status from v$instance;
STATUS
------------
MOUNTED
SQL> alter system enable restricted session;
System altered.
SQL> drop database;
Database dropped.
But then, it AGAIN said that SAPinst has detected an existing DB !!! I went and renamed the inventory file:
$ /oracle/oraInventory/ContentsXML
$ mv inventory.xml inventory.xml.bak
And STILL no luck !! Please kindly advise on how to inform SWPM, that the DB has already been dropped!
Because the only thing I can think of right now is to restore the old DB and drop it with SWPM !!
PLEASE I count on your support! Thanks a lot in advance!
