hi
what are the apps version local and remote database???
Snapshot too old errors occur because Oracle can 't reconstruct a consistent
image of a block for the purposes of a consistent read.
I feel at remote database, you are using UNDO, it will be rather easy to iincrease the undo retention time or increase the undo tablespace size.. if you are dealing with roll back segments, you may have rollback segments whose optimal values are too small...
increase roll back segments size and select again then
