Migration from WAS 3.5.4 to 4.0.1

[Shalini Komarla]

Hey All,
I am new to the newsgroup and this is my first posting. I'm hoping somebody can help me out here.
We're migrating from WAS 3.5.4 to 4.0.1 using the migration tool provided by IBM. I am getting an error 10 when I try and start the admin server. You will find an extract from the error file below.
- We are using DB2 7.3 (7.1.6)
- We are using JDBC 2.0
- The WAS 40 db is on a remote server

I'm not sure if this will help- but if you go to taskmgr- are there any java threads under the processes tab? If there are- kill em. Then try to restart.
I don't think that this is your problem- I think its a datasource issue. Can you look in the DB2diag.log- what does it tell you?

hi,try doing this.first install db and then WAS.am not sure whether this wud solve ur problem
cheers!!!

Hey Matthew,
There are no java processes running, thoug that was a good suggstion. The db2diag.log file also does not contain anything.
Any more ideas?

DB2 was already installed with WAS 3.5. I only needed to upgrade from 3.5.4 to WAS 4.0.1
Also, somebody brought this to my attention, thought I'd pass it along to you as well...
