Recently, my employer want me to pick up some jobs related to oracle 9ias development in the coming future. Since I have never used oracle products, it may a diffcult task to me.

I have the experience on using some RDBMS such as MS Access, MySQL and PostgreSQL.
And some server side script language: ASP and PHP.

I got a PC for the learning purpose: Win2K, 450mhz, 320MB RAM, 15GB harddisk.

I believed that I had installed too much Oracle packages to the PC, it is now too slow. (I'm not sure which package suited me)

What package should I install for learning FORMS & REPORTS?
BTW, Do I need to know JAVA/J2EE well for using FORMS & REPORTS?

Please advise. Thanks a lot.
