SQL1397N failed to log on to the DB2 Service

The following command was run in the db2 command window today:

Db2stop

Then, when we enter db2start, an error is returned !!! "SQL1397N failed to log on to the DB2 service"

Why is the Instance suspended after it is started?

I checked the information on the Internet and said that the password has been changed by the db2admin user. Let's use the following method.

1. Start-> Control Panel-> Administrative Tools-> Services 2. Right-click several services in DB2, choose Properties-> log on, and change the user's password to "new password". login? I have recently changed my password! Try it first! Find one of the db2 services. After completing these two services, start the "db2 --- db2copy1 -- db2" service and report an error !!!! The command db2start is useless and cannot be started. I suddenly thought that I disabled the db2admin account yesterday due to a windows login problem. Why? Find the db2admin account and enable it! Then, use another method to open the "db2 --- db2copy1 -- db2" service. properties ---> log on to the user and select "Local SYSTEM account" for the application. Right-click "db2 --- db2copy1 -- db2" and start! ------ Success !!!! Return to the Command window and run db2stop --- successfuldb2start --- successful!
