Hi Team,
I am using Postgresql 7.4 version. We are willing to update the version to the latest. Can you pls give some guidelines and provide the link to the software to download. Is it free downloadable or commercial, pls advice us. Secondly, we found there is very less performance with the current version. So, we started to do "VACUUM VERBOSE ANALYZE" daily with the help of Cron jobs scheduler. We don't find any effective performance increase in the Database. So, we concentrated on configuration file. In our configuration file "postgresql.conf" where found the following entries commented. And "max_connections = 100", we found that at one particular peak period/timings of the day, the transactions are failing due to database updation. Can you pls suggest us to get rid of this problem. Our ideas on this :- 1) Upgrade to latest version 8.0 2) Increase the "Max_connections" value to 200. 3) Change the configuration file by un-commenting the following parameters. Please advice on this and correct me if I am wrong in the above approach. # QUERY TUNING #----------------------------------------------------------------------- ---- # - Planner Method Enabling - #enable_hashagg = true #enable_hashjoin = true #enable_indexscan = true #enable_mergejoin = true #enable_nestloop = true #enable_seqscan = true #enable_sort = true #enable_tidscan = true # - Planner Cost Constants - #effective_cache_size = 1000 # typically 8KB each #random_page_cost = 4 # units are one sequential page fetch cost #cpu_tuple_cost = 0.01 # (same) #cpu_index_tuple_cost = 0.001 # (same) #cpu_operator_cost = 0.0025 # (same) # - Genetic Query Optimizer - #geqo = true #geqo_threshold = 11 #geqo_effort = 1 #geqo_generations = 0 #geqo_pool_size = 0 # default based on tables in statement, # range 128-1024 #geqo_selection_bias = 2.0 # range 1.5-2.0 # - Other Planner Options - #default_statistics_target = 10 # range 1-1000 #from_collapse_limit = 8 #join_collapse_limit = 8 # 1 disables collapsing of explicit JOINs Regards, G.
