My Oracle Support Doc ID 1445965.1 "Advice For the PeopleSoft Oracle DBA" is the first place you should look.
_unnest_subquery = false
_gby_hash_aggregation_enabled = false.
Parameters to avoid:
optimizer_index_cost_adj - leave at default.
optimizer_index_caching - leave at default.
db_file_multiblock_read_count - unset, dynamically calculated.
cursor_sharing - leave at default of 'exact'.
optimizer_features_enable - leave at default of Oracle version.
Aside from these parameters, look at implementing pscbo_stats (MOS Doc Id 1322888.1)
