Indicator: SUBSCRIPTION_CACHE_STATUS
Definition
Description
This indicator shows the status of the provisioning data cache and its subcaches in each instance of the SAP CC Core Server system. This data cache includes master data related to end customers (subscriber data) of a service provider: subscriber accounts with prepaid and postpaid accounts, provider contracts (and subscriptions) with allowances and relating counters. Only the rater instances and the updater instances of the SAP CC system manage this specialized data cache.
Note
SUBSCRIPTION_CACHE
is the technical name of the
provisioning data cache
managed by SAP Convergent Charging.
Monitoring
You monitor the remaining free memory (
fmem
) and the data objects already removed from the data cache (
rmv
) to determine
if you must increase the cache size (see the
SUBSCRIPTION_CACHE_SIZE
parameter).
Syntax
The SUBSCRIPTION_CACHE_STATUS indicator includes the following information elements:
-
i: The subcache number or '-' (minus) for the whole data cache -

hit: The total number of cache hits since the start of the SAP CC system instance -
put: The number of data objects put in the cache since the instance started -
