[teiid-issues] [JBoss JIRA] Resolved: (TEIID-1204) Re-enable failover support

[ https://jira.jboss.org/browse/TEIID-1204?page=com.atlassian.jira.plugin.s... ] Steve Hawkins resolved TEIID-1204. ---------------------------------- Resolution: Done Re-enabled failover support with in a way that will work regardless of whether global sesisons are used. Will update the docs to indicate that failover is applicable to: 1. connection time 2. post-connection if it's an admin (such as adminshell) or autoFailover is true. Post-connection failover works by sending a ping at most every second to test the connection prior to use. If it fails a new instance will be selected prior to the operation being attempted. The previous approach would retry, which is not appropriate for non-idempotent operations. As before this is not true "transparent application failover" we will not restart the transaction/query/recreate session scoped temp tables, etc. In both of the scenarios servers are connected to using a random selection policy. As part of the load balancing issue, I look at introducing a programatic way to configure selection. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
