Hi

INSERT INTO gtc_xm_heading_translations VALUES(‘anx1_title’,'ПРИЛОЖЕНИЕ I’,'Bulgarian’,'T’)

When i am trying to insert these values into table it’s showing language value like ‘??????????’ instead of ПРИЛОЖЕНИЕ..For all Bulgarian languages its showing values like this.Plz provide solution for this…

Besides a workaround such as
[code]
gpg --keyserver wwwkeys.eu.pgp.net --recv-keys 2E2BCDBCB38A8516
apt-key add /root/.gnupg/pubring.gpg
[/code]
is there any “official” solution to this?

It has a default SID which i named "trans1" during the installation of oracle. It is working fine. Now, I want to create new SID for another big project. How can I create,run and access in enterprise manager? Pliz help! Hello,

Unfortunately I'm not aware if Oracle internally supports any of the available protocols. If you don't know that (just like me) and need a quick solution, create <a href="http://en.wikipedia.org/wiki/Network_File_System_%28Sun%29" rel="nofollow">NFS</a> or <a href="http://en.wikipedia.org/wiki/Server_Message_Block" rel="nofollow">SMB</a> read/write shares (depending on your remote system), mount them and set the local path to the data files accordingly. @Vikas: Generally to access a disk on a remote machine, there should be some kind of protocol for communication.

So I had to dig into the documentation. It says this is total user(/non-system) data limit of the database. Unfortunately, I couldn't find any information about what "system" or "non-system" means. I made some experiments: <ul> <li>I listed all database users with their respective default tablespaces: <b>SELECT "USERNAME","DEFAULT_TABLESPACE" FROM dba_users;</b> The default HR user uses the "USERS" tablespace. </li> <li>I listed all datafiles with their respecive tablespaces: <b>SELECT "FILE_NAME","TABLESPACE_NAME","BYTES","MAXBYTES" FROM dba_data_files;</b> The USERS tablespace was created with 1Gb size and maximum size ot 5Gb. </li> <li>I tried resizing the datafile to something larger: <b>ALTER DATABASE DATAFILE '/usr/lib/oracle/xe/oradata/XE/users.dbf' RESIZE 5000M;</b> and I got an error message saying: "<i>ORA-12952: The request exceeds the maximum allowed database size of 4 GB</i>". However, I was allowed to resize it to 4000M. </li> <li>Ok. Let's say my users.dbf is 1Gb. I tried creating new datafile for this tablespace: <b>ALTER TABLESPACE USERS ADD DATAFILE '/usr/lib/oracle/xe/oradata/XE/users01.dbf' SIZE 4000M AUTOEXTEND OFF;</b> Same error (4+1 = 5). I was able to create a smaller than 3000M datafile. Dropped it. </li> <li>I tried creating a new tablespace: <b>CREATE TABLESPACE USERS2 DATAFILE '/usr/lib/oracle/xe/oradata/XE/users2.dbf' SIZE 1000M AUTOEXTEND OFF;</b> Successfully. I tried creating another one with 3000M size. Error (1+1+3 = 5).</li> </ul> I came to a conclusion it calculates the total size of user datafiles. However, I still don't have an idea what is the mechanism of distinguishing system and non-system tablespaces as I can easily change any users's default tablespace to SYSTEM, for example (something you shouldn't do generally)... I suppose you have to stick to the assumption above or do some further experiments if you want to cheat the database server. In the latter case, I would appreciate if you share your experience here.
