4.1 TADDM 7.2.1 streaming deployment
The TADDM streaming environment offers several key advantages over previous single system or
enterprise sync-mode TADDM configurations. Using a TADDM streaming 7.2.1 environment
(shown in Figure 1: TADDM 7.2.1 Streaming configuration with TBSM) workload is distributed
while operating from a single database. TADDM 7.2.1 single system (not shown) and streaming
environments can run concurrent discoveries and IDML book loads. The discovery management
console is streamlined to provide only discovery related tasks. And the data management portal in
this configuration is dedicated to display the configuration management data that is collected by
TADDM discovery and loaded by the IDML books. The primary storage server is dedicated for
display by the AlwaysBusyStorageServer=true property in the
%TADDM_HOME%/etc/collation.properties file. The image below shows how this property setting
removes a data management portal from the group of storage pool members.
With TADDM 7.2.1 you no longer have to use application templates or application descriptors to
define business applications. Using the data management portal, you can now use the grouping
composer by clicking Discovery > Grouping Composer to define collections, access collections
and business applications. If running a standalone TADDM environment you can use the Grouping
Composer to define business services, however in an environment with TBSM, use TBSM for
business service creation.
TADDM 7.2.1 also introduces improvements to its state event capabilities with new sendOriginGuid
and sendCauses attributes.
In this solution guide TBSM is assumed to be connected to an event object server, and both TADDM
and IBM Tivoli Monitoring are also configured to send events to the EIF probe that is associated
with this object server.
If you have Tivoli Monitoring agents deployed across your enterprise you should consider
performing your discovery through Tivoli Monitoring. Tivoli Monitoring discovery simplifies the
need to manage your access control list.
