Hash_join_enabled=false in oracle 11g

Question

our database 11g, operating system : linux redhat5 datawareshousing database
our database size 4GB, temporary tablespace size 16GB, we have enough pga_aggregate_target space.
We got error message
ORA-01652:unable to extend temp segment by 128 in tablespace TEMP , to resolve it we have set the parameter hash_join_enabled=false
reference:-Re: ORA-01652:unable to extend temp segment by 128 in tablespace TEMP
we cannot tune the query, all queries are dynamic automated queries.
i know, hash_join_enabled is deprecated from oracle 10g onwards.
my question is,
is there any performance problem/issue setting the parameter hash_join_enabled=false for the database for future queries?
looking forward to your valueable inputs.

Rajesh Kumar

And how do you set this parameter in 11gRx?

If you disable hash joins you disable the join method most appropriate for DSS systems.
