Having issues after installing Essbase V9.3.1,configuring the SQL interface

Question

I am having issues after installing Essbase V9.3.1 and configuring the SQL interface. we are using UNIX/AIX box for our Essbase server and UDB DB2 9.1 SP6 as our SQL Interface.
When tried to run an ESSCMD script to perform BUILDDIM operation on Essbase application using the load rule (with the SQL interface), got the error as recorded in the application log file and is attached at the bottom and the .odbc.ini file on the server looks as follows.
Can somebody tell me whether .odbc.ini needs any correction or what else should I do to correct the issue and able to work thru using SQL interface? Appreciate any help provided in this regard. Thanks,
.odbc.ini

I had similar errors when first setting up the SQL interface. Are you on a 64 bit operating system on the essbase server? If so Essbase needs to use the 32 bit odbc driver, not the default 64 bit driver.
The 32 bit driver is still available here SysWOW64\odbcad32.exe <-----This is the 32 bit (Use)
The Administrative tools by default uses system32\odbcad32.exe <----This is the 64 bit (Don't Use)
Once I opened the 32 bit driver interface directly and set it up the errors went away.
