The HADR_TARGET_LIST parameter enables HADR to run in multiple standby mode. Which of the following statements are TRUE if HADR is active? (Choose two.)
You cannot change the principal standby of the primary without first stopping HADR on the primary. Additionally, you cannot dynamically update the HADR_TARGET_LIST configuration parameter for a standby unless you've enabled the HADR read standby feature.
The correct answers are D,E. REFERENCE : https://www.ibm.com/support/knowledgecenter/en/SSEPGG_11.1.0/com.ibm.db2.luw.admin.config.doc/doc/r0059281.html Although you can update the value of the hadr_target_list parameter and have the changes take effect while the database is online, there are some restrictions if HADR is active: 1/ You cannot change the principal standby of the primary without first stopping HADR on the primary. 2/ You cannot remove a standby from the list if it is connected to the primary. To disconnect a standby, deactivate it. Then, you can remove it from the primary's target list. 3/ You cannot dynamically update the hadr_target_list configuration parameter for a standby unless you enabled the HADR reads on standby feature. 4/ You cannot remove the primary database from the target list of a standby if the standby is connected to the primary. 5/ The target list must contain IP addresses that are either IPv4 or IPv6, but not a combination of the two. 6/ You cannot dynamically update the hadr_target_list configuration parameter if you are using the Db2 pureScale Feature.
