Hi All,

I have installed IS 8.5 with one error occurred during the installation.

com.ibm.is.install.exception.InstallException: CDIIN4358E: DB2 could not be started: db2start returned an exit code of -1.

I let the installation go through. But when I login to my workstation, an error in the title pop-out.

Can anyone help me to fix this error?

Thanks in advance.

Set DB2INSTANCE environment variable.

Hi Ray,

It looks like DB2instance variable has set as DB2 and I can see the instance appearing in the DB2 database tree structure.

The error just pops up when I first log in the workstation. It has not stopped my working so far.

I modified DB2intance variable name a few times to try getting ride of the error, but it still not working.

Any other suggestions?

Thanks,

Have you re-booted after changing the environment variable? Often this is required on Windows systems.
