IBM ODM Rules 8.7 - Can you say "Doh" ?

I saw this exception today: -

The initialization of the model failed.
A resource provider error occurred during the loading.
Failed to load the repository.

I realised that I was missing a table or two ( RULEAPPS and RULESETS to name but two ), but I was 100% sure I'd created everything.

I checked my notes: -

db2 connect to RESDB
db2 create bufferpool BP32K size 8000 automatic pagesize 32K
db2 -tvf C:\IBM\ODM87\executionserver\databases\trace_db2.sql
db2 -tvf C:\IBM\ODM87\executionserver\databases\repository_db2.sql
db2 -tvf C:\IBM\ODM87\executionserver\databases\xomrepository_db2.sql
db2 -tvf C:\IBM\ODM87\executionserver\databases\decisionrunner_db2.sql


( For the record, I'm installing ODM Rules 8.7.0.0 on Windows Server 2008 R2 )

Can you see what I did wrong ?

Yes, when I connected to DB2, I did not specify a user - on the Windows platform, the command will use the ID that's currently logged in - Administrator in my case - which means that all objects are created with the schema of ADMINISTRATOR rather than, as required, DB2INST1.

Once I realised what I'd done wrong, I dropped the DB: -

db2 drop db RESDB

and recreated everything BUT with the correct schema: -

db2 connect to RESDB user DB2INST1
db2 create bufferpool BP32K size 8000 automatic pagesize 32K
db2 -tvf C:\IBM\ODM87\executionserver\databases\trace_db2.sql
db2 -tvf C:\IBM\ODM87\executionserver\databases\repository_db2.sql
db2 -tvf C:\IBM\ODM87\executionserver\databases\xomrepository_db2.sql
db2 -tvf C:\IBM\ODM87\executionserver\databases\decisionrunner_db2.sql

I'm sure I could have also used this: -

db2 set current schema DB2INST1

but that's not important right now.
