catpatch.sql有可能运行很慢

估计你没有重新启动数据库到migrate模式下~

按照acheng170的方法作，把数据库关了，然后startup migrate，保证只有你自己可以连入，然后再运行catpatch.sql

During an upgrade from release 9.2.0.1 or later, the catpatch.sql script can take a long time if there are statistics for the SYS schema. Delete the statistics on all of the objects in the SYS schema, and then recollect the statistics after normal database open, if necessary.

To drop and re-create the statistics, enter the following commands in SQL*Plus:

SQL> EXECUTE DBMS_STATS.DELETE_SCHEMA_STATS('SYS');

SQL> EXECUTE DBMS_STATS.GATHER_SCHEMA_STATS('SYS');
