Hello,

How i can improve performance to get information from views (user_ and all_) faster?

My applications use user_tab_columns view and similar to get information about database schema.

sho parameter target:

archive_lag_target                   integer     0

db_big_table_cache_percent_target    string      0

db_flashback_retention_target        integer     1440

fast_start_io_target                 integer     0

fast_start_mttr_target               integer     0

memory_max_target                    big integer 21056M

memory_target                        big integer 21056M

parallel_servers_target              integer     384

pga_aggregate_target                 big integer 5000M

sga_target                           big integer 15040M

Physical memory on server 32GB.
