Post upgrade

• $ cat /etc/oratab
  test11g:/orasw/app/oracle/product/11.2.0:N
• remove the spfile from $ORACLE_HOME/dbs
• remove the and recreate the link to init.ora in $ORACLE_HOME/dbs
• modify the init.ora to add compatible=11.2.0.3.0 (to use oracle 11g features)
• Copy some configures from old Oracle Home

$ cp /orasw/app/oracle/product/10.2.0/network/admin/listener.ora /orasw/app/oracle/product/11.2.0/network/admin/
$ lsnrctl start

• Make sure no application opens files at old Oracle Home

# lsof | grep "/oracle/product/11.2.0"

• Recreate EM DB control repository:

$ . oraenv

ORACLE_SID = [test11g] ?

$ which emctl

/orasw/app/oracle/product/11.2.0/bin/emctl

$ emca -config dbcontrol db -repos create

Possible issues

• For error "The Upgrade Assistant failed in bringing up the database . Oracle Home obtained from file /etc/oratab was used to connect to the database. Either the database is not running from Oracle Home or the correct Initialization Parameter file (pfile) was not found."

Try to remove files on:
$ORACLE_BASE/cfgtoollogs/dbua

And re-try.

• The 11g oraenv may not be working for 10g databases if you have both 10g and 11g databases on the same server. If so you can copy the oraenv from 10g home to /usr/local/bin.
