      public void setMaxSerial(BigInteger serial) throws EBaseException
      Set the maximum serial number.
      Parameters:
      serial - maximum number
      Throws:
      EBaseException - failed to set maximum serial number
    • getNextMaxSerial

      public BigInteger getNextMaxSerial()
      Get the maximum serial number in next range.
      Returns:
      maximum serial number in next range
    • setNextMaxSerial

      public void setNextMaxSerial(BigInteger serial) throws EBaseException
      Set the maximum serial number in next range
      Parameters:
      serial - maximum number in next range

      public BigInteger getMinSerial()
      Get the minimum serial number.
      Returns:
      minimum serial number
    • setLastSerialNo

    • getIDGenerator

      public Repository.IDGenerator getIDGenerator()
    • setIDGenerator

      protected void setIDGenerator(Repository.IDGenerator idGenerator)
    • setIDGenerator

    • initCache

      protected void initCache() throws EBaseException
      init serial number cache
      Throws:
      EBaseException
    • peekNextSerialNumber

      public BigInteger peekNextSerialNumber() throws EBaseException
      Peek at the next serial number in cache (does not consume the number). The returned number is not necessarily the previously emitted serial number plus one, i.e. if we are going to roll into the next range. This method does not actually switch the range. Returns null if the next number exceeds the current range and there is not a next range.
      Returns:
      serial number
      Throws:
      EBaseException - failed to retrieve next serial number
    • setTheSerialNumber

      public void setTheSerialNumber(BigInteger num) throws EBaseException
      Updates the serial number to the specified in db and cache.

      Parameters:
      num - serial number
      Throws:
      EBaseException
    • getNextSerialNumber

      public BigInteger getNextSerialNumber() throws EBaseException
      Retrieves the next serial number, and also increase the serial number by one.
      Returns:
      serial number
      Throws:
      EBaseException - failed to retrieve next serial number
    • getRangeLength

      public BigInteger getRangeLength()
    • getRandomLimit

      public BigInteger getRandomLimit(BigInteger rangeLength)
    • checkRange

      protected void checkRange() throws EBaseException
      Checks if the given number is in the current range. If it does not exceed the current range, return cleanly. If it exceeds the given range, and there is a next range, switch the range. If it exceeds the given range, and there is not a next range, throw EDBException. Precondition: the serial number should already have been advanced. This method will detect that and switch to the next range, including resetting mLastSerialNo to the start of the new (now current) range. Postcondition: the caller should again read mLastSerialNo after calling checkRange(), in case checkRange switched the range and the new range is not adjacent to the current range.
      Throws:
      DBException - thrown when range switch is needed but next range is not allocated
      EBaseException
    • setMinSerialConfig

      public abstract void setMinSerialConfig() throws EBaseException
      Sets minimum serial number limit in config file
      Throws:
      EBaseException - failed to set
    • setMaxSerialConfig

      public abstract void setMaxSerialConfig() throws EBaseException
      Sets maximum serial number limit in config file
      Throws:
      EBaseException - failed to set
    • setNextMinSerialConfig

      public abstract void setNextMinSerialConfig() throws EBaseException
      Sets minimum serial number limit for next range in config file
      Throws:
      EBaseException - failed to set
    • setNextMaxSerialConfig

      public abstract void setNextMaxSerialConfig() throws EBaseException
      Sets maximum serial number limit for next range in config file
      Throws:
      EBaseException - failed to set
    • getNextRangeDN

      public String getNextRangeDN()
    • getNextRange

      public String getNextRange() throws EBaseException
      Gets start of next range from database. Increments the nextRange attribute and allocates this range to the current instance by creating a pkiRange object.
      Returns:
      start of next range
      Throws:
      EBaseException
    • hasRangeConflict

      public boolean hasRangeConflict() throws EBaseException
      Determines if a range conflict has been observed in database. If so, delete the conflicting entries and remove the next range. When the next number is requested, if the number of certs is still below the low water mark, then a new range will be requested.
      Returns:
      true if range conflict, false otherwise
      Throws:
      EBaseException
    • getNumbersInRange

      public BigInteger getNumbersInRange()
    • checkRanges

      public void checkRanges() throws EBaseException
      Checks to see if a new range is needed, or if we have reached the end of the current range, or if a range conflict has occurred.
      Throws:
      EBaseException - failed to check next range for conflicts
    • setEnableSerialMgmt

      public void setEnableSerialMgmt(boolean value) throws EBaseException
      Sets whether serial number management is enabled for certs and requests.
      Parameters:
      value - true/false
      Throws:
      EBaseException - failed to set
    • getLastSerialNumberInRange

      public abstract BigInteger getLastSerialNumberInRange(BigInteger serial_low_bound, BigInteger serial_upper_bound) throws EBaseException
      Throws:
      EBaseException
