升级数据字典，解决ORA-01092: ORACLE instance terminated. Disconnection forced问题。

升级数据字典，，解决ORA-01092: Oracle instance terminated. Disconnection forced问题。

在Oracle 实例关闭的情况下，Oracle 软件从10.2.0.1 升级到 10.2.0.5 之后，存在的数据库也要升级。

此时启动实例会报错 ORA-01092: ORACLE instance terminated. Disconnection forced

SQL> alter database open;

ERROR at line 1:

ORA-01092: ORACLE instance terminated. Disconnection forced

第一步，通过startup upgrade启动实例

SQL> startup upgrade;

ORACLE instance started.

Variable Size 100664456 bytes

Database mounted.

Database opened.

第二步，升级数据字典和实例等。

SQL>@ORACLE_HOME\rdbms\admin\catupgrd.sql

分钟左右

升级完毕显示如下：

第三步，shutdown 实例。Startup实例

第四步，再次编译无效的应用对象

DOC> The following PL/SQL block invokes UTL_RECOMP to recompile invalid

DOC> objects in the database. Recompilation time is proportional to the

DOC> number of invalid objects in the database, so this command may take

DOC> a long time to execute on a database with a large number of invalid

DOC> objects.

DOC>

DOC> Use the following queries to track recompilation progress:

DOC>

DOC> 1. Query returning the number of invalid objects remaining. This

DOC> number should decrease with time.

DOC> SELECT COUNT(*) FROM obj$ WHERE status IN (4, 5, 6);

DOC>

DOC> 2. Query returning the number of objects compiled so far. This number

DOC> should increase with time.

DOC> SELECT COUNT(*) FROM UTL_RECOMP_COMPILED;

DOC>

DOC> This script automatically chooses serial or parallel recompilation

DOC> based on the number of CPUs available (parameter cpu_count) multiplied

DOC> by the number of threads per CPU (parameter parallel_threads_per_cpu).

DOC> On RAC, this number is added across all RAC nodes.

DOC>

DOC> UTL_RECOMP uses DBMS_SCHEDULER to create jobs for parallel

DOC> recompilation. Jobs are created without instance affinity so that they

DOC> can migrate across RAC nodes. Use the following queries to verify

DOC> whether UTL_RECOMP jobs are being created and run correctly:

DOC>

DOC> 1. Query showing jobs created by UTL_RECOMP

DOC> SELECT job_name FROM dba_scheduler_jobs

DOC> WHERE job_name like 'UTL_RECOMP_SLAVE_%';

DOC> 2. Query showing UTL_RECOMP jobs that are running

DOC> SELECT job_name FROM dba_scheduler_running_jobs
