Sybase数据库技术,数据库恢复

 

随着Sybase被完全整合到SAP下，Sybase原来的支持网站被SAP Support Portal取代。
只有购买了SAP服务的用户才能使用账号登录SAP Support Portal进行介质下载、补丁升级、报Incident等。
目前，原Sybase所有产品（包括：Adaptive Server Enterprise、Sybase IQ、Replication Server、PowerDesigner等）的官方手册仍然可以从https://infocenter.sybase.com/help/index.jsp进行浏览或下载。暂不清楚该网站https://infocenter.sybase.com/help/index.jsp何时会被完全迁移到SAP Support上！
Sybase官方手册英文版有html和pdf两种格式，而中文版手册只有pdf一种格式。为了国内Sybase用户更方便、快捷地搜索Sybase常见产品的官方手册内容，特将中文版Sybase官方手册转为html格式！
Sybase产品官方手册中文版的html格式所有内容的版权归SAP公司所有！本博客站长是Sybase数据库的铁杆粉丝！

JDBCExamples 类 ‌ ‌ ‌

// An example class illustrating the use of JDBC facilities

// the serverMain method.
