How can WebSphere Service Registry & Repository (WSRR) information be pre-loaded into the IBM Integration BUS (IIB) cache before sending any messages to the message flow?
A. By subscribing to WSRR notifications.
B. Adding predefinedCacheQueries to a custom policy within WSRR.
C. By using the predefinedCacheQueries parameter in the Configurable Services for the broker.
D. WSRR data cannot be loaded into the IIB cache without sending a message that accesses the WSRR node.
Correct Answer: C
Explanation/Reference:
Explanation:
Enabling cache preloading
After the query file is created and placed on the server, configure the broker to use the text file at execution group start up. The change properties command will be used to achieve this and is accomplished by running the following command:
Command to enable preloading of the WSRR cache from file
mqsichangeproperties <broker_name> -c ServiceRegistries -p
"<wsrr_query_text_file>" -o DefaultWSRR -n predefinedCacheQueries
Replace <broker_name> with the name of the broker that is being used. Replace <wsrr_query_text_file> with the absolute file path location and name of the query file.
