標(biāo)題: 請(qǐng)問ASE15.0.1相對(duì)于ASE12.5.4有哪些實(shí)際功能的提升 [打印本頁] 作者: linda_bin 時(shí)間: 2006-12-30 09:11 標(biāo)題: 請(qǐng)問ASE15.0.1相對(duì)于ASE12.5.4有哪些實(shí)際功能的提升 在ASE15.0.1中增加了群集功能，請(qǐng)問這個(gè)功能是否好部署，好使用？另外就是ASE15.0.1是否對(duì)RS12.6
不支持，即RS12.6只能安裝在ASE15之前的版本上面？ASE15.0.1相對(duì)于以前版本，有哪些功能比較好用，在查詢速度上面是否有實(shí)質(zhì)性的提升？作者: 1017of 時(shí)間: 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 時(shí)間: 2006-12-30 11:32
這里我描述錯(cuò)誤了，ASE15.0.1是講述HA，其實(shí)我們期待的是真正意義上的負(fù)載均衡功能。另外至于查詢速度問題，這個(gè)我們?cè)谙惹皽y(cè)試使用的ASE15中，查詢速度并沒有所講述的那么快，而是耗時(shí)較長。最終給出我們打答復(fù)是需要將我們邏輯頁面大小全面提升到16k，盡管理由不是很充分，我們?nèi)栽谟^望中。另外對(duì)于ASE不兼容RS12.6的問題，我也有描述錯(cuò)誤，就是在創(chuàng)建RS復(fù)制服務(wù)過程中，直接在ASE上面來創(chuàng)建RSSD，是不會(huì)成功的，除非先在ASE上面創(chuàng)建名字為RSSD的數(shù)據(jù)庫，再創(chuàng)建RS服務(wù)時(shí)，把路徑改造剛才創(chuàng)建的RSSD上面作者: 1017of 時(shí)間: 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 時(shí)間: 2006-12-31 10:02
