cache request on python

Chris

I use CachedMessageSubscriptionRequest.cached_first to call cache data

but I got Fail on_completion
CacheRequestOutcomeListenerHandler:CacheRequestOutcome.FAILED, cache_request_id:3 exception:Unable to send cache request.
Caller Description: On cache request send. Error Info Sub code: [1]. Error: [Only SOLCLIENT_CACHEREQUEST_FLAGS_LIVEDATA_FLOWTHRU allowed with wildCard topic xxxx/xxxxxxx on session (c1,s1)_api]. Sub code: [SOLCLIENT_SUBCODE_PARAM_OUT_OF_RANGE]. Return code: [Fail]

What is this mean?

Hi Chris,

This indicates that the API did not get a response from the distributed cache.

• Have you configured theSolCache name correctly in the request?
• Is the SolCache up and active?
• Is your client on the same VPN as the SolCache

There could be other network issues at play as well but for starters these are the most common issues.

Hi Chris,

The PubSub+ API for Python only allows 'as_available' for wild-card topic subscriptions.

If you wish to received cached data before live data, (cached_first), you must use an exact match topic subscription without wildcards ('*' or ending in '>').

Hi Ranger,

Thanks for you answer.
I change the topic to specific subscription.

And the CacheRequestOutcomeListenerHandler's on_completion funcction get Fail.

The exception:"The cache request timed out, this error was generated from event: _SolCacheEventInfo:
Cache Event Type: _SOLCLIENTCACHEEVENT.SOLCACHE_EVENT_REQUEST_COMPLETED_NOTICE(0)
Topic: xxxx/xxxx/x/xxx/xxxx/xxx
Return Code: Incomplete(7)
Sub Code: SOLCLIENT_SUBCODE_CACHE_TIMEOUT(55)
Cache Request ID: 1
Cache Session ID: 2318934085456"

can you tell me why I get this? My topic is simple data I think it don't take much time but I got time out.

Hi Ranger,

Thank you so much. I figure out the problem I don't set the right SolCache name.
