Java EMA: Problem subscribing to realtime and delayed ticker at same time

I'm able to subscribe to delayed names like /IBM.N and /SPY.P, but if I try to subscript to SPY.P, I cannot subsequently subscribe to /SPY.P when the user I'm subscribing with isn't permissioned for real-time.

What I'm seeing is that I try to subscribe to "SPY.P", and I get back a NotAuthorized status in onStatusMsg. When I receive that, I call OmmConsumer.unregister(handle) to unregister the SPY.P subscription, and then attempt to subscribe to "/SPY.P".

However, the consumer thinks I'm just trying to subscribe to SPY.P - I get a second NotAuthorized error and msg.getName() is "SPY.P", whereas it should be "/SPY.P". How can I successfully do this, or do I just have to do something like open up a second consumer for delayed subscriptions?

(I did try creating a second OmmConsumer just for delayed subscriptions, as a workaround, but then the delayed subscription on the second consumer results in a "Received an item event without user specified pointer or stream info" ItemCallbackException.

Looking for any advice on how to handle this.

Thanks,

Shawn

From my test, this problem has been solved in Elektron SDK - Java - 1.1.1.E2. You can download it from here.

Please try it and let us know the result.

My code may be too simple. Please see the attached file. consumerjava.txt

If I use EMA Java 1.1.1.E2, the output is:

StatusMsg
    streamId="5"
    domain="MarketPrice Domain"
    state="Closed / Suspect / Not entitled / 'Access Denied: User req to IDN for Exch - NYS'"
    name="IBM.N"
    nameType="1"
    serviceId="2115"
    serviceName="API_ELEKTRON_EPD_RSSL"
StatusMsgEnd
RefreshMsg
    streamId="6"
    domain="MarketPrice Domain"
    solicited
    RefreshComplete
    state="Open / Ok / None / 'All is well'"
    itemGroup="00 01"
    permissionData="03 08 43 40 17 c0"
    name="/IBM.N"
    nameType="1"
    serviceId="2115"
    serviceName="API_ELEKTRON_EPD_RSSL"
    Payload dataType="FieldList"

From the output, it can subscribe to /IBM.N when IBM.N is access denied.

However, if I use the same code with EMA Java 1.1.1.L1, I get this output.

StatusMsg
    streamId="5"
    domain="MarketPrice Domain"
    state="Closed / Suspect / Not entitled / 'Access Denied: User req to IDN for Exch - NYS'"
    name="IBM.N"
    nameType="1"
    serviceId="2115"
    serviceName="API_ELEKTRON_EPD_RSSL"
StatusMsgEnd


StatusMsg
    streamId="6"
    domain="MarketPrice Domain"
    state="Closed / Suspect / Not entitled / 'Access Denied: User req to IDN for Exch - NYS'"
    name="IBM.N"
    nameType="1"
    serviceId="2115"
    serviceName="API_ELEKTRON_EPD_RSSL"
StatusMsgEnd

The subscribed item will always be IBM.N.

Could you please share your code?
