No start database manager command was issued. SQLSTATE=57019

Question

I am new to DB2 and I have installed DB2 9.7.

I created an instance which is shown below

[sathish@oc3855733574 ~]$ db2ilist
sathish

Settings of /etc/services is shown below

DB2_sathish     60000/tcp
DB2_sathish_1   60001/tcp
DB2_sathish_2   60002/tcp
DB2_sathish_END 60003/tcp
DB2_TMINST      50000/tcp

But, when I start using 'db2start' it throws the following error

07/31/2015 10:26:20     0   0   SQL1042C  An unexpected system error occurred.
SQL1032N  No start database manager command was issued.  SQLSTATE=57019

I installed DB2 using 'root' and starting 'DB2' from 'instance' (sathish in this case)

Any help or URL link will be of great use

Thanks Sathish Kumar

Answer 1

I had a look into db2diag.log file and I got a unusual hack from one of the website

I followed the steps mentioned below and it worked

a)   db2trc on -f db2trace.out
b)   db2start
c)   db2trc off

Answer 2

This problem generally occurs if you have recently changed the password of the account which is the owner of that db2 instance what you need to do is go to services-> properties of the db2 instance -> and then from log on part select local system account

This looks like something is wrong with the installation. There should be some hints on what DB2 ran into in the db2diag.log file (look under ~/sqllib/db2dump/db2diag.log).

What you could do if the db2diag.log does not provide a clue is to verify your installation is correct. DB2 includes a tool for that named "db2val". Here is the link to the documentation of db2val for version 9.7. Just run "db2val" as the instance owner and check the output.
