From ca0c96fc8925d36ea0c5121520bf7d8f12ad90a5 Mon Sep 17 00:00:00 2001 From: Monty Date: Thu, 22 Mar 2018 20:03:54 +0200 Subject: Adjust table_open_cache to avoid getting error 24 (too many open files) MDEV--15609 engines/funcs.crash_manytables_number crashes with error 24 (too many open files) MDEV-10286 Adjustment of table_open_cache according to system limits does not work when open-files-limit option is provided Fixed by adjusting tc_size downwards if there is not enough file descriptors to use. Other changes: - Ensure that there is 30 (was 10) extra file descriptors for other usage - Decrease TABLE_OPEN_CACHE_MIN to 200 as it's better to have a smaller table cache than getting error 24 - Increase minimum of max_connections and table_open_cache from 1 to 10 as 1 is not usable for any real application, only for testing. --- mysql-test/r/connect.result | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-) (limited to 'mysql-test/r/connect.result') diff --git a/mysql-test/r/connect.result b/mysql-test/r/connect.result index 315aea0ef46..cb66ff483e1 100644 --- a/mysql-test/r/connect.result +++ b/mysql-test/r/connect.result @@ -147,7 +147,7 @@ drop table t1; CREATE USER mysqltest_u1@localhost; GRANT USAGE ON *.* TO mysqltest_u1@localhost; -SET GLOBAL max_connections = 3; +SET GLOBAL max_connections = 10; SET GLOBAL event_scheduler = ON; # -- Waiting for Event Scheduler to start... @@ -191,6 +191,13 @@ event_scheduler mysqltest_u1 mysqltest_u1 mysqltest_u1 +mysqltest_u1 +mysqltest_u1 +mysqltest_u1 +mysqltest_u1 +mysqltest_u1 +mysqltest_u1 +mysqltest_u1 root # -- Resetting variables... -- cgit v1.2.1
