SQL1397N failed to log on to the DB2 Service

When I started the command in the db2 command window today, I finally ran the following command: db2stop and then run db2start !!

When I started the command in the db2 command window today, I finally ran the following command: db2stop and then run db2start !!

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-> management tools-> services

2. Right-click several services in DB2 and choose Properties> log on. Change the user password to the new password.

Why? 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,

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,

Db2stop --- successful

Db2start --- successful

Done!
