Chuck,

 

1)       Witango uses persistent restarting, which loads all variables back in from a cache file written out. You can disable this feature in the witnago.ini file. It is normally better to leave it active, and to call a load domain variables type TAF using the startupurl, but note that the startupurl is not functioning properly in early builds of 5.5. Persistent restart also applies to user and custom scopes.

 

2)       If you tested the taf at one domain, and the cron calls another, it is possible for this to happen. This is because in 5.5 the cache is domain aware. Calling @PURGECACHE at one domain, will only clear files at that domain unless you apply the domain=all attribute, which requires the configpasswd to be set.

 

3)       You need to construct a few helper files which will use the force_server_argument to execute the needed function on all your services. This is usually done with a taf that will pass whole requests on to each service using the @URL command. I’ve made variations on this as a TAF and as a custom tag.

Witango 5.5

1. Restarting Witango after an abnormal shutdown reinitializes old domain variables in all the domains.

How’s the best way to make sure domain variables are all cleared on restart no matter how it shut down?    

 

2.  Modified an application that a cron uses and purged the cache for that domain.  Ran the job manually and it was fine.

When the cron ran, it used the old version of the taf again.  How can I prevent this?

 

3. Two servers with load balancing.  The applications for a domain are cached on both servers and the same for domain variables, I think.

Any easy way that when you say “purge”, it purges that domain of both/all servers of variables or applications, depending on what your purging?

 

Any input from people that have dealt with these issues would be appreciated.

 

Thanks,

Chuck Lockwood
