I don’t remember that from 7.6.03, but it’s been over a year since I was 
testing that version.  I am used to seeing (on MANY 7.6.04.01 mid-tiers) the 
flush cache actually trigger the prefetch (like the dialog box says it will) on 
a server that has any cache already – usually from a preload.  It looks like 
now (7.6.04.03) you have to preload again after the flush to get it to go, or 
log in as a user and only get a partial prefetch pertinent to that user.  No, 
clicking on Sync after Flush had no effect.

BTW, changing the 'Authentication Chaining Mode' to Off does NOT stop the 
thread deaths on the AR Server (and yes I restarted the AR server just in 
case), but it adds an entirely new dysfunctional family of ERROR (623) 
Authentication Failed errors to the mid-tier logs for the improper user name, 
as well as a lot of RPC timeout errors.  While this is going on, the mid-tier 
is unusable.  It was so bad on the last two tests that I finally stopped the 
tomcat.

BTW, the only way I have seen to clear out the improper form login names from a 
mid-tier (the Jsmith versus jsmith variety) is to remove that server completely 
from the server list, then add it back.  When LDAP lets Jsmith log in, it 
permanently poisons the cache.

I’m not getting anywhere with the SP3 mid-tier and SP1 AR Server, so I will 
switch over to a complete SP3 environment and do the same sort of testing.

I noticed that in 7.6.03 too – for some reason the customer I am at is using 
7.6.03 despite the general BMC Support advise not to stay there and move up to 
7.6.04. It’s a project they wish to embark on later.

Anyways the cache items sit at 0 until a user logs in even if that means a user 
may or may not log in for an hour... I could run a quick test again to verify 
it..

It looks like something changed in 7.6.04 SP3 – now when you click Flush Cache 
it does zero out all of the files in the \cache folder like SP1, but it no 
longer starts an immediate, complete prefetch – just sits there with nothing in 
the cache.  It did not prefetch until I tried to log in as support staff to 
that mid-tier, at which point the user gets a spinner for several minutes and 
the mid-tier finally BEGINS to prefetch the cache from persistent file.  
Subsequent actions like opening an Incident from the console trigger additional 
prefetch activity – while the user watches the stupid “Loading” spinner.  And 
this is somehow an improvement?.....NOT!  The entire point of preloading and 
prefetching is so that the users NEVER see a delay in loading forms in the 
mid-tier.  Now I REALLY don’t know what settings to use on the mid-tier caching.

I am going to test your note about 'Authentication Chaining Mode' = off as 
well.  We have used that set to ARS – AREA since version 5.1.2 (2003) and 7.1 
(2008) and used it on 7.6.04 in 2011 and knew of no reason to change it.  
Someone in support mentioned that to me last month (setting it to off), but I 
blew it off because he was also telling me that our LDAP server shouldn’t have 
whitespace in the name of a path (Directory Users) that has existed in LDAP 
since it was installed (Novell Identity Manager – in production since at least 
2002).


5. I have noticed that LDAP Authentication doesn't work if we have given any 
WHITESPACE in AREA-LDAP entries in ar.cfg file. Though you have not given any 
WHITESPACE in AREA-LDAP entries, but unfortunately we have one WHITESPACE in 
below entry (ou=Directory Users).

   AREA-LDAP-Bind-User: uid=<username>,ou=Directory Users,o=unt It might be 
single structure name on LDAP Server, but while defining the same structure 
name in ar.cfg file, unfortunately a single WHITESPACE comes.

To avoid this issue, kindly rename the structure name on LDAP Server so that it 
does not contain any WHITESPACE.

Somehow I don’t think our directory services people are going to change their 
decade old LDAP server configuration, which they tell me meets normal LDAP 
standards, just because BMC has figured out how to choke on it.  They actually 
laughed at the comment.

Back to testing… if the 'Authentication Chaining Mode' setting is actually the 
problem now, with 7.6.04 mid-tiers, then I don’t expect that applying SP3 is 
going to have anything to do with correcting it.

I had one of my servers that was restored from production, and 2 days later, 
some form changes we had made in the release were still not sync’d on that 
server…a quick flush of the cache made everything right…so there is obviously 
something not working properly in the Check Interval….have had several such 
situations in the past, so our standing practice is to flush the web cache 
every time we do a deploy ☺

LJ,

Automatic flush based on Definition Change Check Interval parameter works well 
for me :)

Yes, but anyone that has worked with the product for a sufficiently long time 
knows that doesn’t work properly.  I have a migration process that I fire and 
when the process is over, I want it to automatically flush the cache on the 
configured web servers.

Hi LJ,

The cache is automatically flushed based on Definition Change Check Interval  
parameter in the mid tier config page under Cache Settings.

I’m wanting to automate the cache flush and didn’t find anything in the manuals 
about how to go about automating it…any suggestions are appreciated.
