o The CREATE ODATA PRODUCER statement incorrectly states that the
  SERVICE ROOT clause is optional. This clause is required.


o The documentation about updating the DBD::SQLAnywhere Perl Driver
  is incorrect. For information about updating the driver, refer to
  %SQLANY17%\SDK\Perl\readme.txt.


o  UltraLite New Feature - A new parameter named 'kdf_iterations' is now available when you are
   using database encryption. The value is the number of iterations (in thousands)
   of the "key derivation function". This value is the database encryption
   passphrase (the DBKEY parameter) that is processed on database startup. The key
   derivation function makes it more difficult to access an encrypted database by
   prolonging each attack attempt. The default iteration count values are
   30 (thousand) on Mac OS X and 5 (thousand) elsewhere.

   There are two cases when an explicit setting is required:

   1. You are using a very slow device and UltraLite takes too
      long to start with encryption. For example: kdf_iterations=1

   2. You are using a high-end computer and want added security. For
      example, when running on a Windows or Linux desktop: kdf_iterations=100

   This parameter is specified only at database creation.

o In rare cases, SQL Anywhere hangs when starting up on Windows 7 or
  Windows 2008 R2. If it does, then get the following hot fix from Microsoft:

MobiLink
--------

o MobiLink 服务器需要 ODBC 驱动程序才能与
统一数据库通信。可通过以下链接找到推荐用于所支持的统一数据库的
ODBC 驱动程序:

o 有关 MobiLink 支持的平台的信息，请参见:
    http://scn.sap.com/docs/DOC-35654


Relay Server
------------

o Using the Relay Server with Apache 2.4 is not recommended as it
  triggers the behavior identified in Apache Bugzilla issue 53555 (see
  https://bz.apache.org/bugzilla/show_bug.cgi?id=53555).
  Apache 2.2 is the recommended version.


管理工具
--------

o 要针对管理工具启用 Java Access Bridge，
  请编辑辅助功能属性文件并取消最后两行的注释。

  文件显示形式如下:
  #
  # Load the Java Access Bridge class into the JVM
  #
  #assistive_technologies=com.sun.java.accessibility.AccessBridge
  #screen_magnifier_present=true

o Plug-ins may fail to load after you reinstall - If you have previously
  installed and used SQL Central, and then reinstall SQL Anywhere to a
  different installation directory, then the plug-ins do not load.

  请执行以下步骤来修复此问题:
    1. 打开 SQL Central，然后选择“工具”>“插件”。
    2. 注销原有插件。
       从列表中选择 SQL Anywhere 插件然后单击“注销”。
       重复此步骤，直到注销全部 SQL Anywhere
       插件。
    3. 重新启动 SQL Central。插件完成注册。

Relay Server
------------

o When used with Apache 2.4, under some conditions the Relay Server triggers
  the behavior identified in Apache 2.4 Bugzilla issue 53555 (see
  https://bz.apache.org/bugzilla/show_bug.cgi?id=53555). For this reason it is
  recommended to use Apache 2.2 rather than Apache 2.4 in production
  environments.
