Parameters

Name Meaning

Parameter 1

Indicates the alarm cause.

  • 0x00: The board is working properly.
  • 0x01: A database check is performed.
  • 0x02: A periodical database backup is performed.
  • 0x04: The system is running abnormally.
  • 0x08: The database data is inconsistent on the active and standby system control boards.
  • 0x10: Database incremental data fails to be backed up.
  • 0x20: Database incremental data fails to be backed up to the NVRAM.
  • 0x40: Database incremental data fails to be backed up to the flash memory.

Parameter 2

Indicates the errored data storage area.

  • 0x00: OSF1
  • 0x01: OSF2
  • 0x02: DRDB, indicating the reserved memory database
  • 0x03: MDB, indicating the memory database
  • 0x04: TDRDB, indicating the temporary memory database
  • 0x05: database on the CF card
  • 0x06: shared storage area
  • 0x0C: NVRAM storage area

Parameter 3

Indicates the ID of the errored database. Currently, the value ranging from 0 to 255 (that is, from 0x00 to 0xff) is supported.

  • 0x00: The entire storage area is faulty.
  • 0x01 to 0xff: The database with a certain ID is faulty.

Parameter 4

Indicates the details about alarm causes (Parameter 1).

  • When Parameter 1 is 0x01:
    • 0x01: An error occurs when a list file is generated in the storage area.
    • 0x02: An error occurs in database file verification.
    • 0x04: An error occurs in the database record header.
  • When Parameter 1 is 0x02:
    • 0x01: The flash memory space is insufficient, resulting in a database backup failure.
    • 0x02: Syserr check for a database fails.
  • When Parameter 1 is 0x10:
    • 0x02: Syserr check for a database fails.
  • When Parameter 1 is 0x20:
    • 0x01: The NVRAM is exhausted.
    • 0x02: Data headers saved in the NVRAM are abnormal.
  • When Parameter 1 is 0x40:
    • 0x01: The file system in the flash memory fails to generate a small file.

Impact on the System

The DBMS_ERROR alarm has the following impact on the system:

  • The backup of the active and standby databases fails.
  • The database cannot be restored by itself.
  • System configurations may be lost, the execution of some query and setting commands fails, and system functions may be unavailable.
  • If the alarm has been reported, new configurations may be lost after the device is powered off or reset.

Possible Causes

Possible causes of this alarm are as follows:

  • Cause 1: A database operation fails.
  • Cause 2: Data in the database is damaged.
  • Cause 3: A system control board is faulty.

Procedure

  1. This alarm can be cleared automatically. If the alarm persists after two hours, the automatic clear function fails and you need to manually clear it.
    1. If only the standby system control board has this alarm, warm reset the standby system control board only. For details, see Resetting Boards.
    2. If only the active system control board has this alarm, trigger an active/standby switchover. (A manual switchover is preferred. If the manual switchover fails, attempt to remove and then reinstall the active system control board to trigger a switchover.) Then reset the current standby system control board.

      NOTE:
      Manual switchover method: Log in to the NMS and double-click the target NE in the Main Topology. In the board layout diagram that is displayed, right-click the desired system control board and choose Configure Active/Standby Switchover from the shortcut menu. On the page that is displayed, click Query. Then check the value of SCC Board Backup Status. If data exists, select the board and click Working/Protection Switching to perform a manual switchover.

    3. If both the active and standby system control boards have this alarm, warm reset the active system control board to trigger an active/standby switchover. When the active system control board starts, perform a manual switchover. If the manual switchover fails, attempt to remove and then reinstall the board to trigger a switchover. After the switchover, reset the current standby system control board.
    4. Attempt to perform the preceding manual recovery operations one more time. If the alarm still persists, the board is faulty. Replace the faulty board. For details, see Parts Replacement.
  2. When the DBMS_ERR alarm occurs, contact Huawei technical support engineers.
