Troubleshooting Component Connectivity Issues

I get the following error message in the Data Flow Management view:
Administrator tool request to the Administrator Daemon timed out. Verify that the Administrator Daemon is up, verify the connectivity between the Administrator tool and Administrator Daemon.
This error might occur if the interface used for communication among the EDS components is configured incorrectly.
The interface might be configured incorrectly when you install the components in a multihome machine. To resolve this error, perform the following steps:
  1. Verify that the networkInterface property is configured correctly in the configuration files of the Administration components, the EDS Node, and that the clientPortBindAddress property is configured correctly in the Apache ZooKeeper configuration file.
  2. Restart all the components.
    On Windows, open a command prompt window and navigate to the cli/bin directory. Uninstall the Administrator Daemon, LBMRD, UMESTORED, and Apache ZooKeeper services, and then install them again.
    To uninstall the components, run the following command:
    admin_service.bat uninstall
    To install the components, run the following command:
    admin_service.bat install
I get the following error message in the Data Flow Management view:
Unable to communicate with Apache Zookeeper. Verify that Apache Zookeeper is up, and verify the connectivity between the Administrator Daemon and Apache Zookeeper.
This error occurs in the following situations:
  • Apache ZooKeeper is down.
    Navigate to the following directory:
    <ZooKeeper installation directory>\bin
    To verify the status, run the following command:
    ./zkServer.sh status
    If Apache ZooKeeper is not running, use the following command to start it:
    ./zkServer.sh start
  • The Administrator Daemon is configured incorrectly.
    Navigate to the following directory:
    <EDS installation Directory>/admind/config/
    Verify that the zkservers field in the admind.cnf file is pointing to correct Apache ZooKeeper server URL.
I am unable to change the network interface.
This issue might occur after you connect to a new network.
Perform the following steps to set up the network interface after you connect to a new network:
  1. Edit the networkInterface field in the admind.cnf, lbmrd.xml, and umestored.cfg files to replace the IP address with the IP address of the new connection.
    By default, the files are in the following directory:
    <EDS Installation Directory>/admind/config
  2. On Windows, stop the following services:
    • Informatica ADMIND Service
    • Informatica LBMRD Service
    • Informatica UMESTORED Service
    • Informatica EDS Nodes
    • Informatica Zookeeper Service
  3. Stop the Informatica domain.
  4. Update the networkInterface field in the following files to include the new IP address:
    • mnm.cnf located at <EDS Installation Directory>/mnm/config
    • node.cnf located at <EDS Installation Directory>/node/config
  5. Update the clientPortBindAddress field in the zoo.cfg file to include the new IP address.
    By default, zoo.cfg is installed in the following directory:
    <EDS Installation Directory>/zookeeper/conf
  6. Restart the EDS components.
When I start or stop a remote node, I get the following error message:
Passwordless ssh connection between the machines <host name> & <remote host name> is not enabled. 
Enable passwordless connection and try installation again.
This issue occurs if you have not configured passwordless SSH connections.
Before you run the remote installation, enable passwordless connection between the machines where you installed the administration components and the machines where you installed the EDS Nodes.
For more information about configuring passwordless SSH connections, see the Installation and Configuration Guide.
The Administrator tool shuts down unexpectedly after a period of inactivity and I get the following error in the tomcat log file:
2015-02-25 05:51:23,505 ERROR [Domain Monitor] [DOM_10095] The master gateway data in the domain configuration repository was updated during the last refresh time interval 100001.

This error occurs if there is a connectivity issue.
To resolve this error, perform the following tasks:
  1. In the Administrator tool, click the Domain tab.
  2. In the Domain Navigator panel, select the Domain.
  3. Click Properties tab.
  4. Edit the Custom Properties.
  5. In the dialog box that appears specify the name as MasterDBRefreshInterval and the value in seconds. The default value is 8 seconds.
    Informatica recommends that you specify a high value.
  6. Click OK.
  7. Restart the domain.
