datastore cache to XCache - boost your vBulletin · **Released**: 03-02-2007

(note: do not apply this patch on vBulletin 3.7 as it's included already)
This patch allow you to use XCache as a datastore cache in vBulletin. This is definitely your choice if you have installed and enabled XCache on you server already.

Take care that this is a beta version and was not heavily tested. And i'm not familiar with vBulletin source code as i just started reading it today, but i don't have any difficulty reading it thanks to my years of php skill

Take aware that some vB plugin is not compatible with vB_datastore_*, not just vB_datastore_XCache. So, in case you find vB_datastore_XCache won't work, you'd better try datastore to file or memcache. If one of the others works but not vB_datastore_XCache, do report it to me so i can fix it.

Pre-requirement

a working php installtion
a working vBulletin 3.6.5 installtion
a working XCache installtion
set "xcache.var_size = 10M" or so in php ini

Install the modification
for those of you who can't run "patch", u may patch the file manually

download Attachment 61372 (class_datastore_xcache.php)
save the file as vBulletin.3.6/upload/includes/class_datastore_xcache.php
open vBulletin.3.6/upload/includes/class_datastore.php in your favor editor
add a line in class_datastore.php (see below)
update upload/includes/config.php to enable it (see below)

example class_datastore.php after modification:

PHP Code:


			
        }

        return true;

    }

}



// add class_datastore_xcache, enable it in config.php

require_once(DIR . '/includes/class_datastore_xcache.php');

example config.php after modification:

PHP Code:


			


    // vB_Datastore_Filecache  - for using a cache file

// $config['Datastore']['class'] = 'vB_Datastore_Filecache';

$config['Datastore']['class'] = 'vB_Datastore_XCache';

    // vB_Datastore_Memcached - for using a Memcache server

    // It is also necessary to specify the hostname or IP address and the port the server is listening on

Trouble Shooting
q. i have multiple vBulletin instance installed, the seems to mix data after install this plugin
a. this applies to apc too because, if you wanna fix it, try
open class_core.php, look for:
$this->prefix =& $this->registry->config['Datastore']['prefix'];
and modify to:
$this->prefix = $this->registry->config['Datastore']['prefix'] . $_SERVER['SERVER_NAME']; // or HTTP_HOST

q. Warning: unserialize() expects parameter 1 to be string, array given in $a.php on line $b
a. upgrade your plugin/hack that $a.php belongs to, e.g. vbjournal/vbgallery etc. OR open $a.php and locate at line $b, remove unserialize call, e.g.:
replace $var = unserialize($this->data);
with $var = $this->data;
be careful do not remove the whole line, just the unseralize( and )

if u run out of memory- while cacher requaired more memory- in the page u will see OOMs.
to solve it- u just have to increase allocated RAM. as it fit for ur need

mm do u mind to post ur var.cache list's screen shot -how come ur site got that much

:erm: varbiable to be cached

,i know TAZ ..
either ur using temp.cache hack by lendy ?

---
and yes we are using vbseo3 gold + xcache+datastore (this hack) no problem at all

Yes, I'm running lendy's Template Cache. The var list is well over 300 entries long - too long to post.

Right. Though you can also just increase the xcache.size and the xcache.var.size to fix the problem if you haven't maxed it out.

The default is set to xcache.size=32M and xcach.var.size=0M.

My board requires that my xcache.size=140M and my xcache.var.size=2M. I also have my count set to 2 for the number of processors.

As you can see, even though my xcache.size is 140MB and the xcache.var.size is 2MB (even though the variables get most of the hits), this is still way less than the 4GB of system RAM on my server. You do not necessarily need to upgrade your server to fix your OOM problem but simply change a couple of variables in your php.ini.

This is causing errors in vbjournal
https://vborg.vbsupport.ru/showthrea...96462&page=109

I get this when I go to "my journal" area

Warning: unserialize() expects parameter 1 to be string, array given in /journal.php on line 115

Warning: Cannot modify header information - headers already sent by (output started at /home/user/public_html/includes/class_core.php:3118) in /includes/functions.php on line 2801

If I go to journal index I get this

Warning: unserialize() expects parameter 1 to be string, array given in /journal.php on line 115

Yup, this doesn't work with VbJounal.. Also has problems (still) with vbgallery (or photopost vbgallery or whatever). I asked a few times what actions can be done code-wise to fix similar problem with mods, but I received no response. It's too bad because this does help a lot.

I'm Using this hack for quite a long time now, and in the last few days the board seem to be slowing down with no reason, what do i Need to watch in the XCache fields? do i need to increase a var in the settings?
I'm using orban's temp' cach hack, i know that it's in the grave yard but its' working fine for me..

my board is running on C2D server with 2 GB ram.
