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。
考虑到Sybase数据库的初学者或者没有购买原厂服务的Sybase客户情况,现提供SAP ASE/IQ/RS/SDK/SQL Anywhere/PB等产品的BUG信息。
在SAP Support Portal网站或者google上搜索Targeted CR List for ASE,可以看到针对不同版本的CR(CR表示Change Request)简单描述信息列表。
需要注意的是:Targeted CR List for ASE列出的CR虽然绝大多数是BUG,但有一些是更改需求。
以下提供SAP ASE/IQ/RS/SDK/SQL Anywhere/PB等产品的BUG信息!

Database recovery could have failed with assertion 201501 "Page for requested record not a table page or record not present on page". The problem would only have occurred in the event of the database server not shutting down cleanly while dbremote replication was taking place. It would also have been required that another connection revoked CONNECT or REMOTE from the remote user for which the transactions were being replicated. This problem has been fixed. The connection attempting to revoke permissions from the user for which replication is currently occurring will now receive an error indicating "Not allowed while user 'user_name' is actively replicating transactions". The connection attempting to REVOKE permissions will need to wait until replication completes (commit/rollback) before being able to revoke the permissions.
