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/mysqld--help.result | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'mysql-test/r/mysqld--help.result') diff --git a/mysql-test/r/mysqld--help.result b/mysql-test/r/mysqld--help.result index e84921bfa0a..7b78eae185e 100644 --- a/mysql-test/r/mysqld--help.result +++ b/mysql-test/r/mysqld--help.result @@ -1438,9 +1438,9 @@ sync-master-info 10000 sync-relay-log 10000 sync-relay-log-info 10000 sysdate-is-now FALSE -table-cache 431 +table-cache 421 table-definition-cache 400 -table-open-cache 431 +table-open-cache 421 tc-heuristic-recover OFF thread-cache-size 0 thread-pool-idle-timeout 60 -- cgit v1.2.1
