I'm using DB2 9.7 LUW with AIX 6.1. Right now I'm using Data Studios freeware and Control Center. I'm looking for a tool that would work well with DB2 Administration and also include ERD Diagrams (if possible). What about IBM Optim for Database Administrator?

Tell me what you use and how much you like it. Let me know the link where to review also, if possible.

Thank you.
