m using DB2 v8.1 on windows
running DB2start command gives this following error:
sql1032N no start databse manager command was issued

somewhere i read that changing the system password gives this error n so need to reset the password to the previous one.

I actually changed the password n have also resetted it to the previous one but still giving the same error

fire first below command.
db2admin start

@Pawan, if I am not mistaken db2admin is only required if using Control Center.
@Nittal, check the db2diag.log for info. The default path is: C:\Program Files\IBM\SQLLIB\DB2\db2diag.log

you have changed the password of the user running the service for this instance. check that this password is correct or have it reset or use a different user. password for service userid should not be changed

thanks, its working now. I tried in the morning but it gave me that error msg but when i tried again its working fine, dont know what when wrong, i din't tried any option
