Oracle Application Server Identity Management running in a highly available, active-active Identity Management Cluster (IMHA)
***Checked for relevance on 06-Jan-2014***
An SSO login via Portal or OIDDAS hangs:
- The Portal website displays but when clicking Login it takes a long time to display the SSO login page. Once the login page has appeared it is possible to enter the login details, but thereafter the browser permanently hangs
- Login via SSO welcome page is slow but it is successful
- Login via OIDDAS welcome page is unsuccessful; The SSO login page is displayed but after entering login details the browser permanently hangs.
The error_log of the active Identity Management (SSO) node (node1) has following entries
Executing 'opmnctl status' against the running OID and SSO instances shows all components to be 'Alive'.
If the HTTP Server of the active Identity Management (SSO) node is restarted login to SSO is successful in all cases
If the OID or SSO of node2 is stopped using opmnctl then the node1 works fine.
One of the nodes (host machines) of a high availability Identity Management Cluster is deliberately shutdown or unexpectedly crashes (without first cleanly shutting down the OracleAS processes.) The Single Sign-On functionality should nevertheless continue to work because the other node or nodes in the cluster remain up and running. As described above, in practice this is not always the case.
