What needs to be done to shareplex when upgrading oracle database from 32 to 64 bit.
Shareplex is a 32 bit application so it needs the 32 bit libraries.
When 64 bit Oracle is installed, it installs the 32 bit libraries into the lib32 directory. As a 32 bit application, Shareplex needs to point to these 32 bit libraries.
Please make sure that the link in /var/adm/.splex/<SPLEXversion>/<ORACLEversion> is pointing to the 32 bit library (lib32) and not to 64 bit (lib).
Also check the LD_LIBRARY_PATH and make sure it points to 32 bit libraries first and then the 64 bit libraries
