关于oracle invalid components问题的解决(28天)

升级生产的DB，有一些预检查条件，这些需要提前修复，以便在升级的时候不会成为影响进度的绊脚石。

生产中的components有一些显示是invalid状态，从dba_registry中可以查到。

select comp_id,comp_name,status,version from dba_Registry;

还有一些显示是loading.

COMP_ID                        COMP_NAME            VERSION                        STATUS
------------------------------ -------------------- ------------------------------ -----------

                               log Views
CATPROC                        Oracle Database Pack 10.2.0.1.0                     VALID
                               ages and Types
JAVAVM                         JServer JAVA Virtual                                LOADING
                                Machine

让我百思不得其解。

如果显示是Loading，很可能是安装JVM的时候失败。我上次的日志如下。安装没有成功。

                                Machine

生产环境中有的组件显示是invalid，有的组件显示是loading.

对于这种情况，联系之前的系统迁移，原因是之前系统在Unix下，迁移到linux的时候，先用传输表空间（sys下的Objects就没有导出）,在迁移后就留下了隐患。尽管之后又用goldengate来做同步，但是那部分objects还是没法同步导致的。

现在来修复一下这个问题，对于invalid，loaded，loading的修复如下：

SQL> select count(*),owner,status from all_objects where object_Type like 'JAVA%' group by owner,status;
  COUNT(*) OWNER                          STATUS
---------- ------------------------------ -------
     11999 SYS                            VALID

--这个数据明显和预计的差别很大。

需要卸载重新安装。

步骤如下：

ORACLE instance shut down.
SQL> spool full_rmjvm.log
SQL> set echo on
SQL> startup mount
ORACLE instance started.

JAVAVM                         JServer JAVA Virtual Machine                       REMOVED
spool off;

查看日志，看有没有其他的错误。如果没有继续下面的步骤。

SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> set echo on
SQL> spool full_jvminst.log
SQL> startup mount

。。。。。。。很多日志。。。。。
SQL>@?/xdk/admin/initxml.sql
。。。。。。。很多日志。。。。

在执行的时候会耗费一些时间，开另外一个窗口查询dba_registry,就能够看到状态的变化。

check spool log . 看有没有关联的ora-错误。

最后如果没问题，证明这些组件都已经成功安装，重启数据库。
