Hi ALL,
Ive been using postgres for 3 years and now we are having problems with
its
performance.
Here are some givens..
We have 260 subscription tables per Database.
We have 2 databases.
Our main client has given us 250,000 mobile numbers to
deactivate.
--
We we are experiencing
91,000 mobile numbers to deactive it took a week to finish for
1 DB only
the second DB is still in the process of deactivating
Algorithm to deactivate:
we loaded all subscription tables names into a table
we loaded all mobile numbers to deactivate into a table
SQL:
update SUBSCRIPTIONTABLE set ACTIVEFLAG='Y' where mobile_num in
(select
mobile_num from LOADED_MOBILE_NUMBERS)
the script was made is "C"
COFIG FILE:
# This is ARA nmimain
tcpip_socket = true
max_connections = 150
superuser_reserved_connections = 2
port = 5433
shared_buffers = 45600
sort_mem = 40000
max_locks_per_transaction=128
#fsync = true
#wal_sync_method = fsync
#
# Locale settings

# (initialized by initdb -- may be changed)
LC_MESSAGES = 'en_US.UTF-8'
LC_MONETARY = 'en_US.UTF-8'
LC_NUMERIC = 'en_US.UTF-8'
LC_TIME = 'en_US.UTF-8'
.. DB is being vaccumed every week
my box is running on a DUAL Xeon, 15K RPM with 2 G Mem.
that box is running 2 instances of PG DB.
TIA,
