Я недавно развернул FreeRadius 3.0.12, и у меня возникла проблема с количеством строк соединений, которые он делает с oracle DB. Я внес необходимые изменения в файлы oraclesql.conf и radiusd.conf.
См. содержание oraclesql.conf.
sql {
server = "<DB IP>"
login = "<LOGIN>"
password = "<Password>"
# Database table configuration
radius_db = "(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = <DB IP>)(PORT = <PORT NO.>)))(CONNECT_DATA = (SERVICE_NAME = SID)(SERVER=DEDICATED)))"
# If you want both stop and start records logged to the
# same SQL table, leave this as is. If you want them in
# different tables, put the start table in acct_table1
# and stop table in acct_table2
acct_table1 = "radacct"
acct_table2 = "radacct"
authcheck_table = "radcheck"
authreply_table = "radreply"
groupcheck_table = "radgroupcheck"
groupreply_table = "radgroupreply"
usergroup_table = "usergroup"
# Remove stale session if checkrad does not see a double login
delete_stale_sessions = no
# Print all SQL statements when in debug mode (-x)
sqltrace = yes
sqltracefile = ${logdir}/sqltrace.sql
# number of sql connections to make to server
num_sql_socks = 100
# number of seconds to dely retrying on a failed database
# connection (per_socket)
connect_failure_retry_delay = 60
Как видите, num_sql_socks = 100 установлено.

# Number of servers to start initially --- should be a reasonable
# ballpark figure.
start_servers = 25
# Limit on the total number of servers running.
#
# If this limit is ever reached, clients will be LOCKED OUT, so it
# should NOT BE SET TOO LOW. It is intended mainly as a brake to
# keep a runaway server from taking the system with it as it spirals
# down...
#
# You may find that the server is regularly reaching the
# 'max_servers' number of threads, and that increasing
# 'max_servers' doesn't seem to make much difference.
#
# If this is the case, then the problem is MOST LIKELY that
# your back-end databases are taking too long to respond, and
# are preventing the server from responding in a timely manner.
#
# The solution is NOT do keep increasing the 'max_servers'
# value, but instead to fix the underlying cause of the
# problem: slow database, or 'hostname_lookups=yes'.
#
# For more information, see 'max_request_time', above.
#

# Server-pool size regulation. Rather than making you guess
# how many servers you need, FreeRADIUS dynamically adapts to
# the load it sees, that is, it tries to maintain enough
# servers to handle the current load, plus a few spare
# servers to handle transient load spikes.
#
# It does this by periodically checking how many servers are
# waiting for a request. If there are fewer than
# min_spare_servers, it creates a new spare. If there are
# more than max_spare_servers, some of the spares die off.
# The default values are probably OK for most sites.
#
min_spare_servers = 10
max_spare_servers = 20
# When the server receives a packet, it places it onto an
# internal queue, where the worker threads (configured above)
# pick it up for processing. The maximum size of that queue
# is given here.
#
# When the queue is full, any new packets will be silently
# discarded.
#
# The most common cause of the queue being full is that the
# server is dependent on a slow database, and it has received
# a large "spike" of traffic. When that happens, there is
# very little you can do other than make sure the server
# receives less traffic, or make sure that the database can
# handle the load.
#
# max_queue_size = 65536
# There may be memory leaks or resource allocation problems with
# the server. If so, set this value to 300 or so, so that the
# resources will be cleaned up periodically.
#
# This should only be necessary if there are serious bugs in the
# server which have not yet been fixed.
#
# '0' is a special value meaning 'infinity', or 'the servers never
# exit'
max_requests_per_server = 0
# Automatically limit the number of accounting requests.
# This configuration item tracks how many requests per second
# the server can handle. It does this by tracking the
# packets/s received by the server for processing, and
# comparing that to the packets/s handled by the child
# threads.
#
# If the received PPS is larger than the processed PPS, *and*
# the queue is more than half full, then new accounting

Есть ли еще какое-то место, где мне нужно внести изменения, чтобы сформировать требуемое соединение. Мы будем очень признательны за любые рекомендации по этому вопросу. Спасибо
