APAR NUMBER:  PJ30419                         
PRODUCT:  z/TPF
FUNCTIONAL AREA:  CONTINUOUS DATA COLLECTION (CDC)
SHIPPED IN PUT:  1
 

ABSTRACT:
CDC cannot be configured to run with multiple processors in a loosely
coupled complex when using a remote MQSeries server. It is unable to
define remote queues for different CPUs.

COMMENTS:
Continuous data collection (CDC) can be configured to use an external
MQSeries server. When doing so, it uses a transmit queue, a sender
channel, and a remote queue definition. In a loosely coupled
environment, CDC needs to define each one of them for every CPU in the
complex. The examples that are provided in the documentation defined a
remote queue with the same name for each processor because CDC writes
to the same queue when it is using a remote MQSeries server or when it
is using the z/TPF Queue Manager. However, in a loosely coupled
environment, MQSeries will not allow multiple definitions of the same
queue name on different CPUs.
 

SOLUTION:
CDC now uses a uniquely named queue per processor: CDCRTQ. (for
example, CDCRTQ.A, CDCRTQ.B, and so on). This is true even in an
environment that is not loosely coupled. This change also requires
users to download the latest version (Version 1.3) of the CDC client at
http://www.ibm.com/software/htp/tpf/download/tools.htm. The CDC client
also contains a fix for the DASD I/O charts for the Subsystem tabs.
Previously, the systemwide DASD I/Os were shown instead of the
subsystem-specific value.
 
COREQS:
None.
 

MIGRATION CONSIDERATIONS:
