[Maria-discuss] Easy way to see different users@hosts connected to all databases?
by Tanstaafl 18 Jun '14

18 Jun '14

Is there a simple command I can issue to see a list of the current users@hosts connected to all of the databases of a running mariadb server? I'm trying to troubleshoot a problem where an update from 5.5.30 to 5.5.37 recently caused all of the connections from my groupware host to start coming from a different hostname, and so were being denied. I need to be able to see if changes that I make change the hostname being used. Thanks, Charles

[Maria-discuss] New Question: Does Mariadb has a comparison with PostgreSQL ?
by AskMonty KB 18 Jun '14

18 Jun '14

Hello, A new question has been asked in "MariaDB Documentation" by mayuraviraj: -------------------------------- PostgreSQL maintain a page which compare it with MySQL (https://wiki.postgresql.org/wiki/Why_PostgreSQL_Instead_of_MySQL:_Comparing…) Why not mariadb maintain a such information ? It will be very valuable for DBAs and developers ? Also I think it will help mariadb to evolve in certain new areas with the light of PostgreSQL. -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/does-mariadb-has-a-comparison-with-postgresql/

Hi, I'm trying to get innodb_use_atomic_writes = 1 working on an ext4 on top of LVM on a ioDrive device with a RHEL6 kernel 2.6.32-358.6.2.el6.x86_64 and getting the following error. Which bit(s) need to change to get it working? 140611 7:43:46 InnoDB: Operating system error number 25 in a file operation. InnoDB: Error number 25 means 'Inappropriate ioctl for device'.

+ Torben, Dan Hello, DirectFS name has been deprecated and the new name for the Flash aware filesystem from Fusion-io is NVMFS (NonVolatile Memory FileSystem). NVMFS a fully POSIX compliant filesystem is currently in EA (early access) and can be obtained by signup for the program (by reaching out to Torben/Dan cc-ed ). Please note NVM Compression (page-compression) solution stack uses POSIX interfaces only, and is not “directly" dependent on opennvm intrefaces.

But the short answer is that directfs/nvmfs isn't opensource - you only get this if you have a fusion-io card Found this in one of the fusion-io's blogs : " We plan to release directFS as an open source file system to demonstrate the usage and benefits of native interfaces." http://www.fusionio.com/blog/under-the-hood-of-the-iomemory-sdk Best, Nirbhay Fusion-io itself is a commercial product, so nvmfs/directfs is likely from them only (and is probably closed source). I take it others can implement it, but haven't (yet?) ? MariaDB's initial implementation of it is here: http://lists.askmonty.org/pipermail/commits/2013-March/004529.html (and I presume this was then ported to Percona Server as well -- http://www.percona.com/doc/percona-server/5.6/performance/atomic_fio.html) It seems the magic is at: #define DFS_IOCTL_ATOMIC_WRITE_SET _IOW(0x95, 2, uint) I found a presentation that talks about it (nothing about the filesystem itself being opensource): http://www.slideshare.net/fusionio/perconalive-accelerating-mysql-in-open-s… And for reference some older blog posts: https://blog.mariadb.org/significant-performance-boost-with-new-mariadb-pag… https://blog.mariadb.org/mariadb-introduces-atomic-writes/ And attached for brevity, is a short chat I had with Jan Lindström who works on the fusion-io code now: 11:42 < bytee> jplindst: our fusion-io work, is based on the open APIs at http://opennvm.github.io/ correct? 11:46 < jplindst> bytee: To be totally honest, I have no idea what are the API at the http page you mentioned, I have used standard POSIX interfaces to access FusionIO storage, thus you will need FusionIO SSD card and NVMFS file system 11:47 < bytee> jplindst: nvmfs file system - where does one get it ? from fusion-io ? 11:47 < jplindst> bytee: FusionIO card is naturally commercial product, nvmfs to current my understanding does not work with any other device 11:48 < bytee> jplindst: ok, likely because others haven't implemented it 11:48 < jplindst> bytee: correct 11:49 < jplindst> bytee: If you have the card you should have the file system module 11:50 < bytee> jplindst: thanks 11:51 < jplindst> bytee: Last time we did discuss with FusionIO the actual file system was not yet open source 11:51 < jplindst> bytee: not sure if that has been changed now that announcements are out 11:51 < bytee> jplindst: doubt there is, from what i gathere I hope this helps cheers, -colin > > On Tue, Jun 10, 2014 at 5:18 PM, Daniel Black <daniel.black(a)openquery.com<mailto:daniel.black@openquery.com>> wrote: > > Thanks Colin.

[Maria-discuss] Mariadb 10.0.11 "ERROR 2013 (HY000): Lost connection to MySQL server during query". Help fixing?

I'm running Mariadb 10.0.11 on linux/64.

Guys, i'm with a "newbie" question I need to swap a primary key value, for example: create table test ( id int not null default 0, other varchar(255) not null default '', primary key(id) ); insert into test (1,'a'); insert into test (2,'b'); now i want that (2,'b') becomes (1,'b') and (1,'a') becomes (2,'a') the point is, how to do this, with only one UPDATE without duplicate column id value? and without delete values? -- Roberto Spadim
