.... Downgrade of database links with passwords is not supported.
WARNING: --> Deprecated CONNECT role granted to some user/roles.
.... CONNECT role after upgrade has only CREATE SESSION privilege.
WARNING: --> Database is using a timezone file older than version 14.

**********************************************************************
Recommendations
**********************************************************************
Oracle recommends gathering dictionary statistics prior to
upgrading the database.
To gather dictionary statistics execute the following commands
while connected as SYSDBA:
    EXECUTE dbms_stats.gather_schema_stats('DBSNMP',options=>'GATHER'
             ,estimate_percent=>DBMS_STATS.AUTO_SAMPLE_SIZE
             ,method_opt=>'FOR ALL COLUMNS SIZE AUTO'
             ,cascade=>TRUE);
    EXECUTE dbms_stats.gather_schema_stats('OUTLN',options=>'GATHER'
             ,estimate_percent=>DBMS_STATS.AUTO_SAMPLE_SIZE
             ,method_opt=>'FOR ALL COLUMNS SIZE AUTO'
             ,cascade=>TRUE);
    EXECUTE dbms_stats.gather_schema_stats('ORDPLUGINS',options=>'GATHER'
             ,estimate_percent=>DBMS_STATS.AUTO_SAMPLE_SIZE
             ,method_opt=>'FOR ALL COLUMNS SIZE AUTO'
             ,cascade=>TRUE);
    EXECUTE dbms_stats.gather_schema_stats('ORDSYS',options=>'GATHER'
             ,estimate_percent=>DBMS_STATS.AUTO_SAMPLE_SIZE
             ,method_opt=>'FOR ALL COLUMNS SIZE AUTO'
             ,cascade=>TRUE);
    EXECUTE dbms_stats.gather_schema_stats('WKSYS',options=>'GATHER'
             ,estimate_percent=>DBMS_STATS.AUTO_SAMPLE_SIZE
             ,method_opt=>'FOR ALL COLUMNS SIZE AUTO'
             ,cascade=>TRUE);
    EXECUTE dbms_stats.gather_schema_stats('XDB',options=>'GATHER'
             ,estimate_percent=>DBMS_STATS.AUTO_SAMPLE_SIZE
             ,method_opt=>'FOR ALL COLUMNS SIZE AUTO'
             ,cascade=>TRUE);
    EXECUTE dbms_stats.gather_schema_stats('CTXSYS',options=>'GATHER'
             ,estimate_percent=>DBMS_STATS.AUTO_SAMPLE_SIZE
             ,method_opt=>'FOR ALL COLUMNS SIZE AUTO'
             ,cascade=>TRUE);
    EXECUTE dbms_stats.gather_schema_stats('MDSYS',options=>'GATHER'
             ,estimate_percent=>DBMS_STATS.AUTO_SAMPLE_SIZE
             ,method_opt=>'FOR ALL COLUMNS SIZE AUTO'
             ,cascade=>TRUE);
    EXECUTE dbms_stats.gather_schema_stats('WMSYS',options=>'GATHER'
             ,estimate_percent=>DBMS_STATS.AUTO_SAMPLE_SIZE
             ,method_opt=>'FOR ALL COLUMNS SIZE AUTO'
             ,cascade=>TRUE);
    EXECUTE dbms_stats.gather_schema_stats('SYSTEM',options=>'GATHER'
             ,estimate_percent=>DBMS_STATS.AUTO_SAMPLE_SIZE
             ,method_opt=>'FOR ALL COLUMNS SIZE AUTO'
             ,cascade=>TRUE);
    EXECUTE dbms_stats.gather_schema_stats('SYS',options=>'GATHER'
             ,estimate_percent=>DBMS_STATS.AUTO_SAMPLE_SIZE
             ,method_opt=>'FOR ALL COLUMNS SIZE AUTO'
             ,cascade=>TRUE);

**********************************************************************
Oracle recommends reviewing any defined events prior to upgrading.

To view existing non-default events execute the following commands
while connected AS SYSDBA:
Events:
    SELECT (translate(value,chr(13)||chr(10),' ')) FROM sys.v$parameter2
      WHERE UPPER(name) ='EVENT' AND isdefault='FALSE'

Trace Events:
    SELECT (translate(value,chr(13)||chr(10),' ')) from sys.v$parameter2
      WHERE UPPER(name) = '_TRACE_EVENTS' AND isdefault='FALSE'

Changes will need to be made in the init.ora or spfile.

**********************************************************************
**********************************************************************
SYSAUX Tablespace:
[Create tablespace in the Oracle Database 11.2 environment]
**********************************************************************
--> New "SYSAUX" tablespace
.... minimum required size for database upgrade: 500 MB
.
SQL> exit
-bash-3.2$

2.根据检查结果进行相应修改

a.修改系统参数
SQL> alter system set compatible='10.0.1' scope=spfile;

System altered.
SQL> alter system set sga_max_size=1600m scope=spfile;

System altered.

SQL> alter system set db_cache_size=800m scope=spfile;

System altered.

SQL> alter system set shared_pool_size=500m scope=spfile;

System altered.

b.对赋予了connect角色的用户赋予权限
grant CREATE VIEW          to ept;
grant CREATE TABLE         to ept;
grant ALTER SESSION        to ept;
grant CREATE CLUSTER       to ept;
grant CREATE SESSION       to ept;
grant CREATE SYNONYM       to ept;
grant CREATE SEQUENCE      to ept;
grant CREATE DATABASE LINK to ept;

d.进行9208的补丁程序
SQL> spool cc.log
SQL> @/opt/oracle/product/9ir2/rdbms/admin/catpatch.sql

d.生成参数文件,关闭数据库
SQL>create pfile='/opt/oracle/initDB01.ora' from spfile;

去除参数
hash_join_enabled

3.从9ihome拷贝密码文件到11ghome，修改oratab
-bash-3.2$ cat oratab
#

# This file is used by ORACLE utilities. It is created by root.sh
# and updated by the Database Configuration Assistant when creating
# a database.

# A colon, ':', is used as the field terminator. A new line terminates
# the entry. Lines beginning with a pound sign, '#', are comments.
#
# Entries are of the form.:
# $ORACLE_SID:$ORACLE_HOME::
#
# The first and second fields are the system identifier and home
# directory of the database respectively. The third filed indicates
# to the dbstart utility that the database should , "Y", or should not,
# "N", be brought up at system boot time.
#
# Multiple entries with the same $ORACLE_SID are not allowed.
#
#
# *:/opt/oracle/product/9ir2:N
*:/opt/oracle/product/9ir2:N
#DB01:/opt/oracle/product/9ir2:N
DB01:/opt/oracle/product/11g:N

4.在11g下启动数据库，运行catupgrd.sql
-bash-3.2$ sqlplus /nolog

5.修改参数文件，丢弃两个参数，重新启动数据库，运行脚本utlu112s.sql
BACKGROUND_DUMP_DEST
USER_DUMP_DEST

SQL>startup pfile='/opt/oracle/initDB01.ora'
spool ss.log
SQL> @/opt/oracle/product/11g/rdbms/admin/utlu112s.sql

cat ss.log
有省略
