[Sqlrelay-discussion] Problems getting SQLRelay to play nice with DBIx::Class & Mysql

[Tom H. <Tom...@bb...>]

Hi all, first post on this list.

I am looking to use SQLRelay as a db connection pooler for our
application server.=20

We use Perl/Catalyst/DBIx::Class for the application server and MySQL as
the backend database.

I have installed SQLRelay 0.38 with only Perl and Mysql support and it
has compiled and installed ok.

If I use sqlrsh I can connect to my database ok. I also successfully ran
a small test script using SQLRelay::Connection.

However when my application server tries to access the db via sqlrelay I
am having problems.

If I use the drop in replacement modules (for mysql v5.0) and leave my
DBI connection string as dbi:mysql.. I am getting the following errors.

"DBI Connection failed: DBD driver has not implemented the AutoCommit
attribute."
 and=20
"DBI Connection failed: Turning on AutoCommit failed"

If I change the connection string to DBI:SQLRelay.. I get the following
error:

"unknown database SQLRelay - using GenericSubQ dialect"

Can anyone advice what I am doing wrong?
Is DBIx::Class known to have problems with SQLRelay?



I also notice on the FAQ page a table showing why one should use SQL
Relay with different databases. For MySQL it says it does not overcome
Connection delays.

I plan to run SQLRelay on the server where my application holding a
number of connections with MySQL and then connect to SQLRelay via unix
sockets, which in my experience are much faster than TCPIP.

Will this work and will this also not give a performance improvement
over direct connections?


Many thanks, Tom
