multiple domain names mapped to a single IP
Hi, Is there any pros and cons to multiple domain names mapped to a single IP work in MySQL client server setup like in case of httpd webserver there is a concept of VHost having multiple domain names mapped to a single IP? For example :- int-mysqldbserver1.example.com :- 192.168.0.11 int-mysqldbserver2.example.com :- 192.168.0.11 Will there be a issue when i point full qualified domain name in the application which uses mysql client program since both domain names are pointing to the same IP? Any help will be highly appreciable. Regards, Kaushal

Please help me understand about pros and cons of this feature. That very much depends on your workload. I'd say if you're only running MySQL on that host, chances are that it's going to be beneficial. Best you can do is benchmark with production loads - it varies with exact processor type, architecture, versions and build options of all software, et cetera. Hi Johan, Any benchmarking tool you would suggest ? Regards Kaushal -- Bier met grenadyn Is als mosterd by den wyn Sy die't drinkt, is eene kwezel Hy die't drinkt, is ras een ezel

MySQL (mysql-5.0.54)
Hi I am not able to restart MySQL Database Server (mysql-5.0.54) on Gentoo, I see the below information in the mysqld.err file ## 06 6:30:13 [Warning] No argument was provided to --log-bin, and --log-bin-index was not used; so replication may break when this MySQL server acts as a master and has his hostname changed!! Please use '--log-bin=mysqld-bin' to avoid this problem. 080506 6:30:13 - mysqld got signal 4; This could be because you hit a bug. It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail. key_buffer_size=0 read_buffer_size=262144 max_used_connections=0 max_connections=100 threads_connected=0 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 76800 K bytes of memory Hope that's ok; if not, decrease some variables in the equation. thd=(nil) Attempting backtrace. You can use the following information to find out where mysqld died. If you see no messages after this, something went terribly wrong... frame pointer is NULL, did you compile with -fomit-frame-pointer? Aborting backtrace! The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains information that should help you find out what is causing the crash. ## Any ideas Thanks and Regards Kaushal

B) Depending on the OS, this may never complete, as files may constantly still be written to C) Depending on the OS, cp may not be able to take all of those directories for those 1000's of databases as arguments D) If you were doing that, you'd use 'cp -r' The other thing of course is that to copy the files through the filesystem, you have to stop mysql from running so you don't corrupt anything which means your whole database system can't be used. For MyISAM files, mysqlhotcopy of the slave is a workable solution. It's fast, it locks the tables only while copying, and you end up with the same set of files as a cp-based option.
