Parameter

Description

Specifies the service for which the alarm is generated.

RoleName

Specifies the role for which the alarm is generated.

HostName

Impact on the System

The OLdap resources are abnormal and the Manager authentication service is unavailable. As a result, security authentication and user management functions cannot be provided for upper-layer web services. Users may be unable to log in to Manager.

Possible Causes

The LdapServer process in Manager is abnormal.

Procedure

  1. Check whether the LdapServer process in Manager is in the normal state.

    1. Log in to the active management node.
    2. Run ps -ef | grep slapd to check whether the LdapServer resource process in the ${BIGDATA_HOME}/om-0.0.1/ directory of the configuration file is running properly.

      You can determine that the resource is normal by checking the following information:

      1. Run sh ${BIGDATA_HOME}/om-0.0.1/sbin/status-oms.sh. You can view that ResHAStatus of the OLdap process is Normal.
      2. Run ps -ef | grep slapd. You can view the slapd process occupying port 21750.

  2. Run kill -2 PID of LdapServer process and wait 20 seconds. The HA starts the OLdap process automatically. Check whether the status of the OLdap resource is in the normal state.

    • If yes, no further action is required.
    • If no, go to Step 3.

  3. Collect fault information.

    1. On MRS Manager, choose System > Export Log.
    2. Contact technical support engineers for help, detail see technical support.
