I'm having some issues with my NVarchar2 columns that I want to solve
My current NLS_CHARACTERSET is 'AL16UTF16', and therefore I can only create NVarchar2 columns with an maximum extension of 2000 bytes. But I do need a column with 4000 bytes length. How can I create an 4000 NVarchar2 column?
(I do not want to use a CLOB column...only a NVarchar2)
we have an environment with many Oracle databases in different versions (v8, V9, V10 and V11). Besides that, there are many versions of the Oracle Client in use, ranging from V6 to V11. Many of the clients have a TNSnames.ORA and as was to eb expected, many of these are old as well with a lot of (by now) invalid information in there.
Is there any reasonable maximum size to the TNSnames.ORA file?What are the consequences from going over the max size? Are there alternatives to using TNSnames.ora which you would recommend?

I'm currently doing migration from Oracle 10gR2 RDF to Oracle 11gR2 Semantic Technology.I followed the steps on the documentation and successfully created the network using the following:
-----
EXECUTE SEM_APIS.CREATE_SEM_NETWORK('rdf_tblspace');
CREATE TABLE rdf_network_trace (id NUMBER, triple SDO_RDF_TRIPLE_S);
--Created SEQUENCE andTRIGGER FOR rdf_network_trace id
[code]....
when I looked at my Node Ids, they were like +635762253807433724+, +6118969225776891730+. The problem is, I am not the one who is assigning Node Ids, They were automatically generated when inserting TRIPLE data to the rdf table.
Did I miss something when I created my network?
I have a table which have almost 90000 rows.
1. The datatype of some columns is NVARCHAR2. I want to change it to VARCHAR2 and NUMBER for some.
I have written a trigger & procedure to call a webservice from pl/sql procedure. Everything was working fine until I was told to use nchar & nvarchar2 instead of varchar2 as per requirement. Now I am not able to run the procedure and getting errorcode with return response from server.
I didn't changed the width of columns but only datatype. What precautions do I need to take in code while doing this and what could have caused the error only by converting the data type.
have a performance problem with a simple query, for example:
SELECT *

I need to improve the performance of the query. How I can improve it?

how to check the maximum space ever used for TEMP. I want to know it because I need to resize the TEMP and I want to know how small it can be. As I can see from a documentation hURL....max_size is max number of extens ever used in a segment

I want to find the the latest compid for individual types 1 and 2 only within a list of ids. Latest compid is defined as the compid associated with the latest end date (null is treated as the latest end date).
So in the above example for rel_type = 1, compid : 12 is latest, for rel_type : 2, compid : 6 is latest.
Datatype for the tables are :
Id : Number
compid : Number
Rel_Type : Number
enddt : Date
