[OpenSIPS-Users] Opensips caching

[Ben Newlin]

Hi,


Since upgrading to 2.4.4 we are seeing the following logs scrolling nearly continuously on our servers:


ALERT:core:pv_get_param: BUG: invalid parameter type 1836017711

ERROR:core:comp_scriptvar: cannot get left var value

WARNING:core:do_action: error in expression at opensips.cfg:583
ALERT:core:pv_get_param: BUG: invalid parameter type 1836017711

ERROR:core:comp_scriptvar: cannot get left var value

WARNING:core:do_action: error in expression at opensips.cfg:583
ALERT:core:pv_get_param: BUG: invalid parameter type 1836017711

ALERT:core:pv_get_param: BUG: invalid parameter type 1836017711

ERROR:core:comp_scriptvar: cannot get left var value

WARNING:core:do_action: error in expression at opensips.cfg:439



It seems to be related to our use of the json module. We often pass json variable types as parameters to other routes and I believe the errors are caused by that. But it’s hard to say as there are a few different script lines referenced in the errors, but some of them point to return statements and other code sections that don’t really make sense. For example, line 583 referenced in the error above is:

  return(-1);

Any ideas?

No, the dynamic routing module will cache the entire configuration and only read from memory. It must be reloaded when the configuration changes. It’s very quick.

I believe that dynamic routing runs a SQL query every time, I don't think that can be cached, but if you do your own logic in opensips, you should be able to use cashedb_memcached

In the script you have multiple caching options, cache_store and cache_fetch from cachedb_mamcached work without external servers like cachedb_mongo that requires mongodb or other nosql modules.

Hello everyone

what is the best way to implement the caching in opensips. I am doing following

we have a rate table with NPANXX with rate per minute. Every time when we do outbound calls we get NPANXX of dialed number and search it in database. Since in this way it will create a load on cpu for each select query.

Can anyone help me in this also let me know if there is any caching functionality is available in opensips ?
