How do I get ADH to keep the last image in cache when a service is disconnected

tbaker

I'm currently seeing ADH dropping items from the cache as soon as the NI provider disconnects. Has anyone got the ADH to preserve the last image in the cache when a provider is disconnected? Do you know what configuration I might be missing?

The relevant config is below. I've setup the service to autoExpire items after a day and have a cache size of 1000 items for REPUB. I'm only publishing a single RIC at the moment which I can subscribe to whilst the Provider is active. I get 'F10: Not In Cache' as soon as the provider disconnects.

*adh*REPUB*autoExpiryItemBaseline : update

*adh*REPUB*autoExpiryItemTimeUnits : days

*adh*REPUB*autoExpiryItemTimeout : 1

*adh*REPUB*autoExpiryMaxListSize : 0

*adh*hashTableSize : 300000

*REPUB*maxCache : 1000

As soon as the NI provider disconnects I get this message:

<rmds.1.adh.sourceSSLDistribution.sslDispatcher.REPUB: Info: Fri Mar 24 14:58:30 2017> Server "REPUB" stopped for RSSL application "REPUB:2" from instance "****.15". The application terminated the session. <END>

ADS log of a consumer connecting when the NI provider is offline:

<rmds.1.ads: Info: Fri Mar 24 14:58:35 2017> Open Failure for (REPUB:TEST) by (****) at (*.*.*.216) using appId () Text:(F10: Not In Cache)<END>

I found leaveInactiveItemsInCache configuration in ADH. I have tried it and it works.

*adh*leaveInactiveItemsInCache : True

The consumer got the following status message when the NI Provider disconnected.

StatusMsg
    streamId="5"
    domain="MarketPrice Domain"
    state="Open / Suspect / None / 'Application Inactive'"
    name="IBM.N"
    serviceId="4811"
    serviceName="API_SHOGUN_NI"
StatusMsgEnd

The new consumer got the cache image with Open/Suspect.
