From Array Suite Wiki
Default value = libsqlite3.so.0
This is the path to the libsqlite3 library file.
This is usually located in /usr/lib/libsqlite3.so or /usr/lib64/libsqlite3.so but may be different for each system (i.e it could be libsqlite3.so.0 or libsqlite3.so.0.8.6).
Set this to the correct full path to ensure that ArrayServer finds the sqlite3 library if using Sqlite as the database for ArrayServer.
