Event ID 8198 — Server for NIS Functionality -- Push Service

Updated: December 16, 2008

Applies To: Windows Server 2008 R2

red

Server for NIS synchronizes and propagates NIS map changes to UNIX-based NIS subordinate (also known as slave) servers. The NIS master server supports the following transfer modes:

  • Periodic transfer of NIS maps
  • On-demand transfer of NIS maps to subordinate servers

Typically, NIS maps are transferred to subordinate servers upon change by using the make utility. The Windows-based NIS server does not use make; instead, the server pushes immediately.

Subordinate NIS servers can request transfer of maps at any time. Server for NIS Server Functionality -- Push Service provides information to help you interpret system messages indicating the functional state of the NIS map push service.

Event Details

Symbolic Name: MSG_PUSH_STOPPED
Message: Server for NIS yppush service has stopped.

Diagnose

An error occurred while the Server for NIS service was running. Server for NIS service failures typically occur for one or more of the following reasons:

  • Cannot communicate with Lightweight Directory Access Protocol (LDAP) service
  • Insufficient memory

The following procedures can help you diagnose the cause of the problem.

Cannot communicate with LDAP service

To verify LDAP health:

  1. Open the Services snap-in.
  2. Verify that the LDAP service is running.
  3. If the service is running, refer to the resolver, "Start the domain controller service."

Insufficient memory

To verify virtual memory:

  1. Right-click My Computer and then click Properties.
  2. On the Advanced tab, in the Performance area, click Settings.
  3. On the Advanced tab of the Performance Options dialog box, in the Virtual Memory area, view the amount of virtual memory allocated on the machine.
  4. Click Change to view the maximum allowable virtual memory.
  5. If necessary, change allocated virtual memory to the size recommended in the Total paging file size for all drives area of the Virtual Memory dialog box.
  6. If virtual memory use is set to maximum, perform the steps in the resolver "Correct memory error."

Resolve

To resolve this issue, use the resolution that corresponds to the cause you identified in the Diagnose section. After performing the resolution, see the Verify section to confirm that the feature is operating properly

Cause

Resolution

Cannot communicate with LDAP service

Start the domain controller service

Insufficient memory

Correct memory allocation error

Start the domain controller service

Server for NIS was unable to communicate with the LDAP service. Possible causes of this error can be either of the following:

  • The server on which Server for NIS is running is no longer an Active Directory Domain Services domain controller.
  • The LDAP service is not running.

To resolve this problem:

  1. Open the Services MMC snap-in (Services.msc) by clicking Start, pointing to Administrative Tools, and then clicking Services.
  2. Verify that the Active Directory Domain Services domain controller service is running.
    • If the domain controller service does not exist, the computer is probably not a domain controller.  Server for NIS can run only on an Active Directory Domain Services domain controller. To promote the computer to a domain controller, see the Active Directory Domain Services Help. Run the dcpromo utility and view the Help available with the dcpromo wizard.
  3. If the service is not running, double-click the service in the results pane.
  4. On the General tab of the Properties dialog box, set Startup type to Automatic. Click OK.

Correct memory allocation error

Memory allocation has failed in Server for NIS. This can occur if the Windows Server operating system has insufficient virtual memory. Try closing some applications and programs that are not required and are using large amounts of virtual memory, and then restart Server for NIS. If this fails to correct the problem, try restarting the computer.

If the problem persists, verify that the computer is not configured to use the maximum amount of virtual memory:

  1. Right-click My Computer and then click Properties.
  2. On the Advanced tab, in the Performance area, click Settings.
  3. On the Advanced tab of the Performance Options dialog box, in the Virtual Memory area, view the amount of virtual memory allocated on the machine.
  4. Click Change to view the maximum allowable virtual memory.
  5. If necessary, change allocated virtual memory to the size recommended in the Total paging file size for all drives area of the Virtual Memory dialog box.
  6. If you have changed the allotted virtual memory amount, click Set, and then click OK.

Verify

Server for NIS push service functionality can be verified by pushing maps to subordinate servers.

To test the functionality of the push service, change a map entry for an NIS user (you can use the users nisadmin or AdminUI for the purposes of your test). Wait for the refresh interval to elapse, and then view the NIS map stored on a UNIX-based subordinate of the master server. If your changed values are reflected in the NIS map stored on the UNIX-based NIS subordinate server, then the Server for NIS master server is functioning as expected.

In the absence of any of the following error messages, the push service is functioning normally. If any of these messages occur, the push service can continue working, but warning conditions exist.

  • IDMU Server for NIS event 8198
  • IDMU Server for NIS event 12288
  • IDMU Server for NIS event 12289
