as/400 using os/400 which is similiar with aix but totally different. Forget them if you didn't work for them before.

完全不一样。 没用过OS/390,用过一点点 MVS/IMS , 完全不同于OS/400. 想学习 IMS 我有 PC上的模拟器。 600多兆,应用不太多。可以学个初步。

我如何能得到您所说的IMS PC上的模拟器呢? 谢谢!

Many developers like RPG for OS400. It's easy compare with UNIX. MVS, VMS and VM are very difficult for beginners. The developer should learn CICS. Visualage make it easier.

OK! Do you know anything about IBM CPCS?

Check Processing Control System(CPCS), I heard that system running in Central Bank of China, but never used it. Pls read books at given link.

Yes, I have viewed that web-site already. I just want to discuss something with you. Thank you all the same.

Finally, found a mainframe professional! Are you system administrator or developer? I would like to discuss some system issues with you.

恐龙级的系统,应该进博物馆,该考古学研究的了。如果不熟悉30年前的办公室环境,你连联机帮助都看不懂。

界面环境相似,但是在基本概念以及管理方面的差别比较大!

差别大了,基本是两个不兼容系统。一般mainframe指运行OS/390(z/OS)的体系结构,AS/400属于midrange(小型机),运行OS/400。我也是OS/390系统管理员。

在国内的?加拿大的?加拿大还有多少公司用mainframe的?

many big companies use mainframe. and the programmers are getting older. :)

能否详细介绍点情况?在国内做mainframe的,不过倒真的没想到在这里能找相关的工作的。

I am not a mainframe programmer, but I do know many governments, big retailers, banks they use mainframe. try do some cold calls.

很多Mainframe系统都外包(outsourcing)给专门服务公司(IBM,EDS等), 例如CIBC, Scotia Bank, TD, etc...这导致了mainframe的工作机会很少.

我一直以为OUTSOURCING是只外包系统管理和硬件维护.不知道你说的是否包括软件应用开发?

部分是包括的。国内很多银行的软件开发都是包给大公司的。

对,很多包给ibm什么的。

我现在在加拿大。这里几乎所有大公司都使用mainframe. 特别是金融行业或传统行业。不过没有听说有VSE系统的。

那这里的应用反而是比国内大了。请问是否知道这里的mainframe是用什么语言做开发的?
-cuptea(一壶茶);

就我所知,大多数应用很有些年头了,无一例外使用COBOL,基于IMS或者DB 2数据库。新的应用也有使用Java和C的。现在的OS/390有部分符合UNIX的POSIX标准,跟AIX相似.
-hunterz(Hunter);

(#953782@0)

这么说来,我找工作的希望还是很大了。我做了3年的mainframe,熟悉cobol, jcl, db2, ims, 不过对cics不熟悉。
可是我接到的phone interview都是中介的,而且也没有下文了。
能找到工作吗?

VSE is an old mainframe OS of IBM, now it 's placed by Z/VM
