Server Administration :: How To Know Character Set As Single Character Or Multi Character

Sep 26, 2013

how do we know database character set is either single character set or multi character set?

While changing character-set from AL32UTF8 to WE8MSWIN1252 got "ORA-12712: new character set must be a superset of old character set".

Below are steps taken to resolve the issue -

ALTER DATABASE CHARACTER SET WE8MSWIN1252;

i got this error: ORA-12712: new character set must be a superset of old character set

below are the commands executed by me:

SQL> SHUTDOWN IMMEDIATE;
SQL> CONNECT SYS/password AS SYSDBA;
SQL> STARTUP MOUNT;
SQL> ALTER SYSTEM ENABLE RESTRICTED SESSION;
SQL> ALTER DATABASE OPEN;
SQL> ALTER DATABASE CHARACTER SET INTERNAL_USE WE8MSWIN1252;
SQL> SHUTDOWN;
SQL> STARTUP;
SQL> QUIT;

And its working...

I have not done it in proper order. Neither have done ccsscan. Still, no user reported any issues. Do my changes truncated the data?

Inserting Character From Extended ASCII Character Set?

Mar 8, 2007

I'm trying to insert a character from the extended ascii character set. Specifically, there's a company that has an accented e (�) in the name. Right now, the company name doesn't have the e at all, accent or no accent. So I'm trying to do an update, something like

update table1 set company_name='blah�" where company='blah'

It runs, but doesn't do the update. Even when I try to forcefully do an insert (instead of an update) I get nowhere; the accented is simply dropped. So the basic question is, how do you insert extended ascii characters into oracle?

Globalization :: Character Encoding - LATIN-1 Character In UTF-8 DB?

Feb 9, 2013

I am using C++ OCI LIB, to insert some report data from remote OCI client to oracle 11 server. This data is read by another process to create the report.The DB CHARSET is UTF-8. But the report tool expects the data to be ISO08859-1 encoded. So while inserting the data into the database i specify the following LANG and CHARSET for my table colulmn in client:

The TARGET DB CHARSET is UTF-8
NLS_LANG=AMERICAN_AMERICA.WE8ISO8859P1
size_t csid = 871; // UTF-8
OCIAtrSet((void *) bnd1p, (ub4) OCI_HTYPE_BIND,
*(void *)&csid*,
(ub4) 0,
(ub4)OCI_ATTR_CHARSET_ID, errhp);

This solution works for almost every case of ASCII and Extended ASCII Charest but we are facing issues if we have few specific characters to be inserted.f we are trying to insert single beta character [β] through client, the data goes empty to the column.

Beta Character details:
DEC     OCT     HEX     BIN     Symbol           Description
223     337     DF     11011111     ß     Latin small letter sharp s - ess-zed

DB Output after insert single β:
select rawtohex(NAME) from PERSONS where EID=333;

RAWTOHEX(NAME)
---------------------------

But if the string is *"ββ"* everything work fine:
DB Output for "ββ":
select rawtohex(NAME) from PERSONS where EID=333;

RAWTOHEX(NAME)
---------------------------
DFDF

I was trying to connect to SQL server from Oracle using Oracle heterogeneous services (HS).But I found that I do not have HS installed on my system. It was mentioned in Oracle website that we need to run 'caths.sql' script under the path $ORACLE_HOME/rdbms/admin.

But I do not have any such folder(rdbms) in my $ORACLE_HOME.What does it mean? And how can I install HS alone on my system(Since I already have oracle)

Heterogeneous Connectivity :: Change When Moving System Using Gateway ODBC?

Jan 27, 2013

Oracle 11gR2
Linux 6.x
Sybase 12 (on Windows)
unixODBC 3.2.x
Sybase Client 12
------------------------

Given the following files or structures that are important to the proper operation of the ODBC Gateway connecting to a remote Sybase database:

listener.ora
tnsnames.ora
initmydblink.ora ( my version of the initdg4odbc.ini )
dblink (not a file but the dblink in the Oracle database)
odbc.ini
odbcinst.ini

What files (and what properties within those files) may/must be changed if the remote Sybase db and system is different (i.e. the Sybase database source has been changed to something 'new')? For example, I can that the odbc.ini file is going to have to be alterer to point to the new database server IP address, database port, database name?

Memory Of Each Connection?

Currently weblogic has 120 concurrent connections to the database.There is a requirement to scale up the number ofconcurrent connections to 300.We have did some study and quite be quite sure that the current sga and pga is required. (the additional connections will be firing the same sql which is very well tuned.

However each additional connection to the database will take up additional memory just for the connection?Will is be using the memory in the PGA? Or outside the PGA for the connection overhead?We are not using MTS.
