Hi Alberto, With systemd it will be as easy as creating additional unit files ( one for > each memcached instance) with its corresponding config file. That should > allow to stop / start / restart each memcache instance individually while > also being systemd compliant. Thanks for the info and for the examples. It really does make sense the way you explain it. Thanks for letting me know!...

Hey guys, OK so I'm pretty familiar with how to edit an init script for memcached so that I can get multiple memcached 'buckets' when starting up the service. The init script would ususally have multiple lines such as these under the start function: # cache_block /usr/local/bin/memcached -d -m 128 -l `hostname -i` -p 11318 -u daemon -c 8172 -v 2>> /tmp/...

...ng sqlite3 as this app will be deployed in an environment where having a standalone app, easily launchable via Locomotive, will be necessary, but the server will not be under really high load. Anyways, to try to speed up the database reads I made my models subclasses of cached_model, and set up memcached. It''s clearly working, as I see the gets and puts in my log. However, cached_model and memcached have if anything slowed everything down. I''m still seeing SQL queries that seem extraneous. For example: Rendering gallery/browse MemCache Get (0.182419) active_record:Entry:6...

Hi all, I need to install the latest memcached version (1.4.20) on a number of machines in this environment. There are only rpm's of this app for RHEL 6. But we need to install the latest memcached on a number of RHEL 5 machines. To be specific, they are OEL 5.7 hosts. I've installed all of the developers tools that I would need. Bu...

Could someone please elaborate on the technical differences and practical impact of whether choosing memory-based tables in MySQL or using memcached. I got this far on my own: It seems that MySQL uses the NDB engine for transaction-safe memory access in a cluster. the memory storage engine seems to be faster but not synchronizable by any means in a cluster. memcached seems to be ultimately fast but requires extra effort in your code. Who...

Hi - Just downloaded and installed the memcache-client and cached_model gems and am trying to test it out on a development setup. I added this to my environment/development.rb CACHE = MemCache.new :c_threshold => 10_000, :compression => true, :debug => true, :namespace =...

...I''ve been using Mongrel for quite some time now but I ran into an issue that threw me back to lighttpd + fastcgi. The application in question was running fine in the production environment with SQLSessionStore and using a mongrel cluster behind a load balancer. However, by switching to a MemcacheSessionStore (using either memcache-client or Ruby-MemCache), users kept being logged out due to the fact that the processes lost their connection to the memcache server (they reconnected but the users were already "logged out"). The funny thing is that this behaviour didn''t occ...

Hi, I''m using mongrel-0.3.13.3 with memcache-client-1.0.3 for storing sessions. It was working fine with actionpack-1.12.0, but when I upgraded to actionpack-1.12.3, I started getting a "can''t convert String into Hash" error from memcache.rb from memcache-client. I was able to fix it by changing the way the MemCache objec...

I was just testing the memcache server on a Windows box and had set it up as a Windows Service and to my surprise (or my shock really) it was using 47+ meg of ram with no data even loaded in it yet. Has anyone else used the Windows port of memcached for their Rails projects and if so how much ram was it using? Does memcach...

Hi, Is anyone here running memcached + python2.6 + django setup on a CentOS 5.5?? Am trying to set one up here and have trouble with the python26-memcached installation. So far i have installed (via yum): 1.python26 2. python26-memcached 3. libevent 4. memcached-devel Now when i try to run `import memcac...

Hey guys, I'm trying use check_memcached.pl to monitor a couple of memcached services running on two ports. I have my command definition setup like this: # 'check_memcached' command definition define command { command_name check_memcached command_line $USER1$/check_memcached.pl -H $HOSTADDRESS$ -p $ARG1$ } And I have my...

I''m at the bloody forehead stage, so I figure it''s time to ask. After installing the robot coop''s memcache-client which everyone apparently recommends, it refuses to work because the rails cache.rb is invoking the read() method on the cache, which it _does not have_. Their library has get() and put() but no read() and write() as rails expects. What gives? Is everyone quietly writing wrapper librari...

After much effort I upgraded our fairly large Rails app from 2.1 to 2.3. After deployment yesterday I noticed an across the board increase in response times. It seems that every call to memcache now takes 10x longer than before. Here are some example numbers from my development log (below), with memcache running locally. We see similar scale of performance drop in production as well - average memcache call before 2ms, now 20ms. It adds up to a significant hit. Before Rails 2.3 upgrad...

Hi all - I am trying to get rails to use memcache for sessions and fragment caching. I''d also like to use the same connection for general caching of this and that. I''m following the instructions here: http://wiki.rubyonrails.com/rails/pages/HowtoChangeSessionStore and hitting a brick wall. I''m using the new memca...

Hello all, We know that memcached or memcached-client doesn''t support regex... But It seems it doesn''t support expire_fragment either :/ I''m trying to use expire_fragment with memcached as following : expire_fragment(:controller => ''home'', :action => :list_posts) But apparently...

Hi all. I am thinking about installing memcached with replication, I've found http://sourceforge.net/projects/repcached/files/repcached/2.2.1-1.2.8/ but it is for 1.2.8, and for Centos 6.3 memcached is in version 1.4.4. I do not want to use client side "replication" (writing to two memcached nodes at the same time) and haven't...
