oracle9i的erp数据库无法正常关闭的解决方法。

场景:
[oraprod@erpdb1 ~]$ ./stopdb.sh

You are running addlnctl.sh version 115.3

Shutting down listener process PROD ...

addlnctl.sh: exiting with status 0

You are running addbctl.sh version 115.7

Shutting down database PROD ...

hang住在此，不能继续正常关闭。

1)查看alert日志。看到如下语句 ：
[oraprod@erpdb1 bdump]$ tail -f alert_PROD.log
Completed checkpoint up to RBA [0x210fb.2.10], SCN: 0x094a.f71170bc

Active call for process 22809 user ‘oraprod‘ program ‘oracle@erpdb1.arp.cn (TNS V1-V3)‘
Active call for process 31347 user ‘oraprod‘ program ‘oracle@erpdb1.arp.cn (TNS V1-V3)‘
Active call for process 437 user ‘oraprod‘ program ‘oracle@erpdb1.arp.cn (TNS V1-V3)‘
SHUTDOWN: waiting for active calls to complete.

发现有三个用户保持连接导致，数据库无法正常关闭。先直接杀掉进程。
kill -9 22809
kill -9 31347
kill -9 437

数据库正常关闭。
