A change to this parameter does not take effect until you use the -SET SYSPARM command to bring it online. Even if you start or restart Db2 after changing the value, the change is not honored until you issue the -SET SYSPARM command.

In Db2 data sharing, all members must use the same setting. When changing the setting of ENCRYPTION_KEYLABEL for a data sharing group, make the change on all members before running the -SET SYSPARM command on any member.
