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.

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。

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：

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> spool full_jvminst.log
SQL> startup mount

。。。。。。。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。
