Building MQTs --> deadlock

Hallo everyone,

I have 3 Tables:
1. Table_01 --> fact table
2. Table_02 --> fact table
3. Table_03 --> dimension table

Aim:
Building of MQT_Table_01 and MQT_Table_02

I have successfully built a MQT on Table_01. The computing of MQT on Table_01 involved Table_03. It means, in order to build Table_01, db2 needs to read Table_03. MQT for Table_02 needs also Table_03

I recognize, if I paralelly build MQT_Table_01 and MQT_Table_02, db2 runs into deadlock. I thought, it might be because of the parallel read transactions in Table_03. But is it really the reason? I am thinking, if db2 just reads, it should be okay? There is no exclusive lock, isnt it?:shocked:

Thank you for the comments.

Regards,
Ratna
