Providing logical member name in JDBC_PING ------------------------------------------ Key: JGRP-2362 URL: https://issues.jboss.org/browse/JGRP-2362 Project: JGroups Issue Type: Feature Request Affects Versions: 4.0.17, 4.0.18, 4.0.19, 4.1.0, 4.0.20 Reporter: S Pokutniy Assignee: Bela Ban Priority: Minor Fix For: 4.1.2 When using JDBC_PING and logical names instead of UUIDs and one of the cluster member crashes or get killed and this member is not coordinator then its database set still remains in the database as long as coordinator changes (independently from remove_old_coords_on_view_change /remove_all_data_on_view_change). If the the cluster is then restarted the old dataset makes connect() much slower (+30 seconds), as the members seem to be tryting to connect to it. Parameter remove_all_data_on_view_change seems to be the solution but it does not work as long as coordinator does not change, so practically the same as remove_old_coords_on_view_change. The only solution seems to be to provide an appropriate delete statement in parameter initialize_sql, which would delete old entry, for example like this: delete from JGROUPSPING where ping_data like '%logical name%'. However, this is neither really quick nor the ideal solution, as ping_data's datatype is bytea or bit varying. It would be great to have also logical name in JGROUPSPING, which is instead per default in insert(). This is also easy to implement as there is access to this information in PingData.
