Remove ADS Cache

weishengtay

i am using ads pop configuration for our system.

How do i remove cache ADS (downstream connectivity to ads), so every time downstream is subscribing a RIC, it will get a new image.

Hello @weishengtay

Thank you for contacting us. I found the ADS-cache related parameters on the ads_pop.cnf file as follows:

!++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
!
! *ads*${svc}*cacheLocation : ssl
!#help
!    cacheLocation: { ssl, srcApp }
!
!    Inidicates where the data cache will be maintained.
!    ssl    - The data cache will be maintained in the ads.
!    srcApp - The data cache will be maintained in the source application,
!              i.e, the ads will not cache data.
!
!    Note: Setting this parameter to srcApp has no affect on aggregated
!    services. To disable caching, use domainsCached and domainsNotCached.
!
!    Default value: ssl
!#end
!++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
!
! *ads*${svc}*cacheType : sinkDriven
!#help
!    cacheType: { sinkDriven, sourceDriven }
!
!    sinkDriven   - The cache content is determined by sink/network demand.
!                   A sink-driven server is allowed to add an item to its
!                   cache only upon the reception of an Open request.
!                   This type of server functions as an interactive datafeed
!                   handler and was formerly called a "Selective Cache" server.
!    sourceDriven - The cache content is determined solely by the source
!                   application/ datafeed. Network demand has no bearing on
!                   the contents of the cache. A source-driven server is
!                   allowed to add an item to its cache at any time.
!                   This type of server functions as a broadcast datafeed
!                   handler and was formerly called a "Full Cache" server.
!
!    Default value: sinkDriven
!#end

! [Source Service]
!++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
!
! *ads*domainsCached :
!#help
! domainsCached: Defines a list of domains for which caching is enabled.
!
! If domainsCached variable has entries, then any domain not in the list
! will not be cached.
!
! For example, to cache only level 1 data:
!      *ads*domainsCached: MARKET_PRICE
!
! If the variable domainsCached have entries then it takes precedence in
! the processing and the variable domainsNotCached is ignored.
!
! To enable caching for all domains:
!      *ads*domainsCached: ALL
!
!#end
!++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
!
! *ads*domainsNotCached :
!#help
! domainsNotCached: Defines a list of domains for which caching is disabled.
!
! If domainsNotCached variable has entries, then any domain other than the
! entries in the list will be cached.
!
! For example, to disable caching for level 2 data:
!     *ads*domainsNotCached: MARKET_MAKER, MARKET_BY_ORDER, MARKET_BY_PRICE
!
!#end
