c++ - another mysqld process using the same InnoDB data or log files -

-

i have mysql server running on linux system. i'm running 1 c++ prog building data base current date , time stamp. i'm trying run process in c++ accessing different db i'm having error.

error below:

innodb: check not have mysqld process innodb: using same innodb data or log files innodb: unable lock /var/lib/mysql/ibdata1, error: 11

please can explain whats going wrong in here

thanks

this page: http://dev.mysql.com/doc/refman/5.0/en/external-locking.html

talks "external locking" can turned on or off myisam databases support multiple servers on 1 set of data. not seem apply innodb however. , page: http://book.opensourceproject.org.cn/lamp/mysql/mysql5cert/opensource/0672328127/ch42lev1sec1.html

says it's not possible innodb because can done on read-only filesystems, , innodb not work on those.

so seems answer cannot it, 2 reasons: first because still populating db while wanting read it, , second because using innodb rather myisam.
