How to solve the SQL1032N error in DB2

DB2It is very common to have problems during the operation process. In this case, some error codes will appearQL1032NErrors are one of them. The following describes how to solve the SQL1032N error in detail.

The error SQL1032N has been reported several times since DB2 was used. The error message is as follows:

11/21/2004 22:15:33 0 0 sql1_2c an unexpected system error occurred. SQL1032N has not issued a command to start the database controller. SQLSTATE = 57019.

After each problem, I went to the Internet to find a lot of information and asked a lot of people. I took some effort to get it done. The Cause and solution of several errors are different. After the solution, I only made a simple record. I always wanted to write them down, so it was convenient for me to come up with the same problem. People who looked around like me also wrote some nonsense, such as how to find errors, even useless work. The first SQL1032N error occurs. A DB2 instance suddenly fails to be started one day. The following error message is displayed when db2start is used:

11:28:39 0 0 sql1_2c an unexpected system error occurred. SQL1032N has not issued a command to start the database controller. SQLSTATE = 57019.

The first time I encountered such a problem, I thought it would be because the database was not ready. I tried any commands in a hurry, such as activating the database only for classes. I couldn't even start the instance, if you run these commands at that time, they will certainly not work.

Later, I suddenly found that when I started the machine, I was prompted that a service failed to start due to an error. Therefore, I thought that the DB2 instance service set to auto-start in the Window service was not started normally, I manually start it in the service, and the following error is prompted:

Windows cannot start the DB2-DB2-0 on your local computer. For more information, see System Event Logs. and refer to the specific service code-8000. view the event manager with such a record:

DB2-DB2-0 SERVICE stopped due to 4294959296 SERVICE error. Source service control event ID: 7024

After doing so much, all of them are useless. Only when you know that the service is unavailable, it means you are not looking for it.

Later, I found the reason through various inquiries: License expired.

Run db2licm-l on the db2cmd interface. It is obvious that the license has expired.

Knowing the cause, the rest is trying to solve the problem.

Summary: until now, in some forums, I often see people posting this kind of post, at least three times in two months. Therefore, if it is not possible to check whether permanent authorization is available, it is not a bad thing to use db2licm-l to check the situation. There is also a situation where, similar to the above, the above SQL1032N error occurs when the instance is started. The DB2-DB0 service cannot be started in Windows NT Service, and the prompt is:

Error 1069, Logon Failure error.

This error is simple. It is caused by an incorrect user name or password used to start the service. In service properties, select the login tab, select the user, and fill in the password to restart the service.

Summary: in this case, it usually happens when the user logs on to the NT System or changes the password of the DB2 user.

Through the above methods and the ability to easily solve the SQL1032N error phenomenon, the fault is solved, you can continue to work, if you encounter similar situations in the future, you can easily solve it, I hope you will be able to make some gains from the content mentioned above.
