Connect fail after upgrade db from 11.1.0.6 to 11.1.0.7

 Hi guys,

   My OS is Linux 32.

   Today I upgrade db from 11.1.0.6 to 11.1.0.7 with steps bellow:

   1. Download the patchset 6890831 from MOS.

   2. Extract this patchset, and run runInstaller to upgrade.

   3. Processing of upgrade success.

   4. I startup my db and received error: ORA-39700: database must be opened with UPGRADE option

   5. I use STARTUP UPGRADE and can start my db.

   6. When use "conn / as sysdba" ==> connect OK, but with "conn sys@develop as sysdba" ==> connect fail with error: ORA-12526: TNS listener: all approriate instances are in restrict mode.

   7. I edited tnsname.ora file by add the "UR=A" and can connect to db with sysdba user (conn sys@develop as sysdba == > OK).
