Last updated on JULY 16, 2020

Applies to:

Information in this document applies to any platform.

Symptoms

On : 12.2.1.3.0 version, DIP Integration

Issue: Directory Integration Platform (DIP) 12c High Availability (HA) Installation - 2nd Node "wls_ods2" dipStatus shows as "Down"

Example Situation Description

 - Integrated with Oracle Unified Directory 12c HA Setup in this case (however the same issue can occur when using OID 12c as well).
 - Created DIP12c 2 managed servers (wls_ods1 and wls_ods2) by following the guide:

Fusion Middleware High Availability Guide (Release 12.2.1.3.0)
Chapter - 12 Configuring High Availability for Oracle Directory Services Components
https://docs.oracle.com/en/middleware/fusion-middleware/12.2.1.3/ashia/configuring-high-availability-oracle-directory-services-components.html#GUID-E03DBA73-41AC-4B7E-95E2-AE68C0021C92

 

https://docs.oracle.com/en/middleware/fusion-middleware/12.2.1.3/ashia/configuring-high-availability-oracle-directory-services-components.html#GUID-E03DBA73-41AC-4B7E-95E2-AE68C0021C92

 - After following all the steps in the guide, the primary "wls_ods1" DIP HA Node is working fine, but the 2nd Node "wls_ods2" is not working, and reports "Down" status. 


Example Environment Details

The environment involved may include the following Setup, and specific behaviors:

OUD Server Status

 - OUD 12c - 2 nodes, connected via a Load Balancer.
 - Both clear-text and SSL mode server-authentication works.
 - SSL connectivity works in server-auth mode via the Load Balancer when checking with the following command:

ldapsearch -h <HOSTNAME> -p <PORT_NO> -U 2 -W <PATH_to_PASSWORD_FILE> -P -b "" -s base "(objectclass=*)" namingContexts

wls_ods1 Status Example

$> ./dipStatus -h <HOSTNAME> -p <PORT_NO> -D weblogic
[Weblogic user password]
Connection parameters initialized.
Connecting at HOSTNAME:PORT_NO, with userid "weblogic"..
Connected successfully.

ODIP Application is active at this host and port.


wls_ods2 Status Example

$> ./dipStatus -h <HOSTNAME> -p <PORT_NO> -D weblogic
[Weblogic user password]
Connection parameters initialized.
Connecting at HOSTNAME:PORT_NO, with userid "weblogic"..
Connected successfully.

ODIP Application is down at this host and port.
