i am using mysql_server-4.1.23 and in the documentation of 4.1
(http://dev.mysql.com/doc/refman/4.1/en/dynamic-system-variables.html) , it is mentioned
innodb_thread_concurrency variable can be set at runtime.
but i am getting error when trying to set dynamically ..
mysql> SET GLOBAL innodb_thread_concurrency=4;
ERROR 1193 (HY000): Unknown system variable 'innodb_thread_concurrency'
still throws error when tried as set @innodb_thread_concurrency and set global
can you please let me know whether 4.1 documentation is misleading or this is a bug in
mysql-4.1 (as in, this variable cannot be set at run-time) ?
PS : i am able to set innodb_thread_concurrency variable at runtime in mysql-5.1 .. but
this is not an option for me now .. i have to go with 4.1 at this point ..
