"no support for dlopen()" . How does this apply to Windows clients? We always build first on Windows and once we have no errors of any kind we build on Linux if the application exists for that platform (what MONyog does and SQLyog does not) and fix what issues may occur there. This issue has occurred with SQLyog (and as such for a Windows client). I am not coder/developer myself, but on Windows I think we have no other option than statically linking? We could of could compile the API as a .dll, but we don't (because we had a lot of problems with it earlier). -- Peter On Thu, Jun 6, 2013 at 3:25 PM, Sergei Golubchik <serg(a)mariadb.org> wrote: > Hi, Peter! > > On Jun 04, Peter Laursen wrote: > > We have the same problem.

[Maria-discuss] New Question: 100% RAM and Swapping
by AskMonty KB 05 Jun '13

Hello, A new question has been asked in "MariaDB community" by danezpz: -------------------------------- Hi, Having recently converted our cPanel servers from MySQL to MariaDB we're having issues with MariaDB using 100% of a servers RAM and swap when a customer optimises a table. This doesn't happen under normal circumstances and only when an optimize is run. Any ideas what's cause this? The servers have 16GB RAM and use the following my.cnf: http://paste2.org/P3cZzBHN Using MariaDB 5.5.30 Any help would be appreciated Thanks -------------------------------- To view or answer this question please visit: http://kb.askmonty.org/en/100-ram-and-swapping/

[Maria-discuss] New Question: Schema Missing after upgrading from MySQL 5.5.8 to MariaDB 5.5.31
by AskMonty KB 05 Jun '13

05 Jun '13

Hello, A new question has been asked in "Getting, Installing, and Upgrading MariaDB" by reustmd: -------------------------------- My OS is Windows 7 64-bit. I used the MariaDB msi installer. I uninstalled MySQL and installed MariaDB. I then launched sqlyog and it only found the standard mysql schemas (e.g., information_schema, mysql, performance_schema). My application schema appears to be missing. I also tried running "mysql_upgrade --verbose" and that didn't seem to help. Should I have to do something else? Thanks! -------------------------------- To view or answer this question please visit: http://kb.askmonty.org/en/schema-missing-after-upgrading-from-mysql-558-to-…

We have the same problem. We cannot test either. But we have a few user reports. We will discuss what we can do. Is there any parameter or compile-time option we should be aware of? Any specific documentation somewhere? Anything? -- Peter On Tue, Jun 4, 2013 at 2:19 PM, Sergei Golubchik <serg(a)mariadb.org> wrote: > Hi, Peter! > > On Jun 04, Peter Laursen wrote: > > For clarity: a 'dummy' parameter doing nothing does not solve our > > problem.

For clarity: a 'dummy' parameter doing nothing does not solve our problem. We actually want to build clients that can (also) connect to Oracle MySQL Enterprise servers configured to make use of Oracle's PAM implementation. -- Peter On Tue, Jun 4, 2013 at 11:05 AM, Peter Laursen <peter_laursen(a)webyog.com>wrote: > yes .. in the Connector/C.

[Maria-discuss] Clear-text plugin
by Peter Laursen 04 Jun '13

This is a continuation of https://mariadb.atlassian.net/browse/CONC-25. We requested support for the clear-text plugin (or a workaround of any kind) that would allow a client compiled with the MariaDB connector to use PAM authentication with MySQL Enterprise servers from Oracle. I will not dispute Sergei's opinions about Oracle's implementation. But I believe it misses the point. The question is if the MariaDB connector should be a replacement for the C-IPA from Oracle. And the question is nothing else than that. Not the quality of solutions bundled with Enterprise servers from Oracle. I would like to hear opinions not only from 'core developers' like Sergei, but also from wider circles in MariaDB organization (management, marketing) as well as the user community. For us the problem is like this: We introduced support for the clear-text plugin in SQLyog 11.1. In 11.12 beta2 we replaced Oracles connector with MariaDB (and had to removed it again). We had a few crashes and memory leaks with mariaDB Connector but that is getting in control now (ther were bugs in both the API and in oru code). We probably could patch the MariaDB code without much problems to support the full-text plugin - but we don't have a MySQL Enterprise server to test with and we cannot release without proper testing. We have already started getting complaints from users/customers about that what we introduced in 11.1 has been removed in current development tree. It seems that we have quite a lot of customers using Oracle's Enterprise servers wiht Oracle's PAM authentication. A solution/workaround would very much be appreciated. Regards Peter Laursen Webyog
