We are facing a problem in Oracle Geodatabase, where we are unable to create feature dataset & classes/ with Arabic names. When I create feature dataset in Oracle Geodatabase its displaying following msg "It item was not found" but feature database is being copied there. but data is not copying after I rename feature dataset and again displaying message "It item was not found" and when i delete feature dataset so that delete easily but after i refresh in geodatabse then All feature dataset come again. Can you help me out in this problem?
You didn't provide any information on any of the software in use, but any modern software should be able to handle this, IF you've configured the database correctly.
What character set did you establish for the database? What NLS_LANG have you defined on the clients? Have you verified that you can use the desired character set from SQL*Plus on both the server and from clients?
You probably want to ask this question in an Oracle forum. If you do, be sure to provide complete software version information (e.g., "Oracle 184.108.40.206.6 server with 220.127.116.11.0 client")
PS: You're more likely to get responses to your questions if you don't mark them as answered (the green check) in the question.
Okay, so I believe that the WE8MSWIN1252 character set makes that database instance useless for international characters. You need to drop and recreate the instance, and choose the UTF-8 character set at creation. Then you need to set the NLS_LANG to the appropriate value before loading. Follow the Oracle documentation for international character set support.
Please can you tell me how can i change UTF-8 character and which one and also NLS_LANG which one i will use ? and can you send me any link for Oracle documentation for international character set support?
It's a option on the installation procedure (the advanced installation procedure).
After 25 years as an Oracle DBA, install has become a reflex; I'm not really capable of describing it to a novice. Besides, Oracle installation details are really outside the scope of these Esri forums.
If you are going to administer an Oracle geodatabase, you really ought to have some Oracle administration training. If Oracle training isn't possible, then I'd suggest using an RDBMS more suited to casual administration.
