Scenario: Oracle Application have two Server. One Server have Forms node, Reports node, Conucrrent node, Admin node, Apache node. Second Server have all node other than concurrent node. One Server went down due to some hardware issues. We have to change the concurrent node to Second Server. Solution: Navigate to Concurrent -> manager -> Define. query the concurrent manager change the primary node to Second server name. Bounce the concurrent manager in second server, check the concurrent manager has started or not. Note: If you configure printer on first server, you need to change that into second server. Copy the /etc/hosts, /etc/profile, /etc/printers.conf from first server to second server. Bounce the concurrent manager and check the printer is enabled or not by check like below $lpstat printer name
