Anyone have any luck getting this to work?

If so, can you post the code sample?
Nimbostratus
iControl.LocalLBRAMCacheInformationRAMCacheKey key2 = new iControl.LocalLBRAMCacheInformationRAMCacheKey();
LocalLBRAMCacheInformationRAMCacheEntry[] RamE;
Interfaces m_interfaces = new Interfaces();
m_interfaces.initialize(ipAddress, user, pass);
key2.maximum_responses = 500;
key2.profile_name = "";
RamE = m_interfaces.LocalLBRAMCacheInformation.evict_all_ramcache_entries(); <-- Not sure what to put here
I've tried entering the key2.maximum_responses and key2.profile_name, but get either invalid arguments, or method doesn't take x arguments.

It should work as long as your HTTP Profile Name and Partition match.

Thanks for the response. However, I don't think that's going to work. What we're trying to do is be able to query the ramcache entries for a specific profile, and only evict on the specified one, instead of clearing the cache for all profiles. Unless I'm misinterpreting your post?

There are three methods for doing this:
evict_all_ramcache_entries Resets/evicts all cache entries. BIG-IP_v9.0.5
evict_ramcache_entry Note: This function has been deprecated. Please use evict_ramcache_entry_v2. Resets/evicts the cache entries associated with the specified keys. Note: The "max_responses" field in each RAMCacheKey key is ignored in this method. BIG-IP_v9.0.5
evict_ramcache_entry_v2 Resets/evicts the cache entries associated with the specified keys. Note: The "max_responses" field in each RAMCacheKey key is ignored in this method.
The first takes no input and flushes the entire RAMCache.
The second was deprecated.

Parameter Type Description
keys RAMCacheKey[] The keys used to evict the RAM cache entries.
exact_match boolean Whether to look for an exact match for host and uri. If exact, you must specify host and uri in the key. If non-exact, host and uri can be a subset of the text in a matched entry during the search.
I haven't used this method yet but I am currently working on a thick client application for this and will post the method when I have it completed.

We figured this out, with the great wonder that is dubdub. I was instantiating the keys incorrectly, which was causing the error. While we did have to use the evict_ramcache_entry_v2 method due to the original one being deprecated, we were able to get this to work to specify which http_profile we wanted to clear the cache for.
LocalLBRAMCacheInformationRAMCacheKey prof_key = new LocalLBRAMCacheInformationRAMCacheKey();
LocalLBRAMCacheInformationRAMCacheKey[] keys = new LocalLBRAMCacheInformationRAMCacheKey[] { prof_key };
Interfaces m_interfaces = new Interfaces();
m_interfaces.initialize(ipAddress, user, pass);
prof_key.host_name = "";
prof_key.maximum_responses = 500;
prof_key.profile_name = "";
prof_key.uri = "";
m_interfaces.LocalLBRAMCacheInformation.evict_ramcache_entry_v2(keys, false);
Thanks for your help!
