What is cache in ClearCache and DoNotCache?

In an application that subscribes to MarketPrice instruments using EMA Java, I would like to preserve for a later use the Data I receive via Refresh and Update messages.

Are fragmented ANSI Page images supported by the ADH cache?
We encode into a standard buffer size of 1490 bytes - to reduce the memory footprint of the app (buffers are pre-allocated) and reduce the need for further packet marshalling. However we have noticed that When ANSI images are fragmented across two messages only the 2nd part appears to be cached and late joiners only get a…

totalCountHint incorrectly set by API for multi-part refresh
The documentation for RsslMap indicates totalCountHint should contain an approximate total for the entire map across a multi-part response. When specifying a hint of zero or none at all the library automatically fills in the count of each single refresh instead. Is this expected?

RsslMap not sent as encoded
I encode a RsslMap in a particular order, e.g. 912810RN0=TWEB 912810RP5=TWEB 912810RQ3=TWEB 912810RS9=TWEB I feed this into a value-add payload cache (rsslPayloadEntryApply) and extract (rsslPayloadEntryRetrieve) on each client request. With RSSL tracing enabled though the ordering is different: <mapEntry flags="0x0"…

ADS not updating it's cached image for a replaced Map Entry
Hi, Both the RFAJ v7.5 and UPAJ v8.0 Developer Guides document that an ADD Action on an OMMMapEntry (OMMMapEntry.Action.ADD in RFA terms) is used to add or replace an entry. We are using this Action to affect a Map Entry replace however, it seems as though the ADS (v2.5.0.L1 in our case) is instead ignoring the update and…

How to query the Coherence cache for metrics?
Regarding Coherence cache metrics, how can I find the key size? The key size is a wrapped java object, for example a 32 character guid. When the POF wrapper is put on it, it ends up being 35 bytes. To be perfectly accurate you would have to query in cache and grab metrics around its key size. POF isn’t fixed, a different…
