当sa用户的密码忘记或sa用户被锁定时，可以使用如下方法进行解锁和重置sa用户的密码。
1. 关闭ASE数据库
isql
>shutdown
>go
2. 在RUN_servername文件中添加-T4044
-psa参数.
inspur5:/sybase/T66/ASE-16_0/install # pwd
/sybase/T66/ASE-16_0/install
inspur5:/sybase/T66/ASE-16_0/install # cat RUN_T66
#!/bin/sh

3. 启动ASE数据库，在启动的控制终端窗口中会显示新的密码
/sybase/T66/ASE-16_0/bin/startserver -f /sybase/T66/ASE-16_0/install/RUN_T66

4. 使用启动控制界面中的密码登录数据库，并解锁sa用户和重置sa的密码
inspur5:/sybase/T66/ASE-16_0/install # isql -Usa -Pqedahlqmtcypg6
-ST66 -X
1> sp_locklogin sa,'unlock'
2> go
Account unlocked.
(return status = 0)
1> sp_password qedahlqmtcypg6,ASE16_test,sa
2> go
Password correctly set.
(return status = 0)
5. 把RUN_servername文件中的-T4044
-psa参数移除后，重启ASE数据库即可正常使用sa登录.
inspur5:/sybase/T66/ASE-16_0/install # isql -Usa -PASE16_test -ST66 -X
1> sp_helpdb
2> go
