不支持，即RS12.6只能安装在ASE15之前的版本上面？ASE15.0.1相对于以前版本，有哪些功能比较好用，在查询速度上面是否有实质性的提升？作者: 1017of 时间: 2006-12-30 09:49
first of all,I never heard cluster package or function has been added to this version.it is said that would be available up to version 15.1.
secondary,I still never heard rs 12.6 would not be supported by ase 15.if that's true,it would be so bad.
last,according to handbooks of ASE 15,query plan and optimizer had been redesigned,and it will provide powerful engine than before.And more practical partition functionality came true.作者: linda_bin 时间: 2006-12-30 11:32
这里我描述错误了，ASE15.0.1是讲述HA，其实我们期待的是真正意义上的负载均衡功能。另外至于查询速度问题，这个我们在先前测试使用的ASE15中，查询速度并没有所讲述的那么快，而是耗时较长。最终给出我们打答复是需要将我们逻辑页面大小全面提升到16k，尽管理由不是很充分，我们仍在观望中。另外对于ASE不兼容RS12.6的问题，我也有描述错误，就是在创建RS复制服务过程中，直接在ASE上面来创建RSSD，是不会成功的，除非先在ASE上面创建名字为RSSD的数据库，再创建RS服务时，把路径改造刚才创建的RSSD上面作者: 1017of 时间: 2006-12-30 12:50
I am not familiar with RS,so no more things can be exchanged with you.
query efficency depends on many factors.I don't know what exactly changes have been made in ASE,but it seems they just improve their optimizer and something correlated.these changes can not make all be done.different problems need different ways.finding the root problem is the gate to the heaven.作者: linda_bin 时间: 2006-12-31 10:02
