Datafile name error
Oracle -18.104.22.168 64bit
My query goes like this.
a fellow dba has added a datafile to oracle database but when i query the name of datafile through views i get vierd characters
At oS level > /oracle/db/data10.dbf
At oracle SQL PROMPT on server > /oracle/db/data10^?^?.dbf
Through a other os via client > /oracle/db/data10.dbf=
nOW I WANT TO rename it . I cant take tablespace offline and do a rename because the name doesnt match if i copy. i tried to copy file by command
cp /oracle/db/data10.dbf /oracle/db2/data10.dbf
i get error >> no such file exists
if i use
cp /oracle/db/data10* /oracle/db2/data10.dbf
then it gets copied.
Now what the only option i think would be create a new controlfile and it wud a downtime..... which i strictly want to avoid.....
cant u advice me the best possible soln ......
Data file can be renamed or moved via 2 methods:
1. alter database command
do copy at os level
alter database rename file 'old' to 'new';
alter database open;
2. alter tablespace command
Take the tablespace offline;
(in another session move or rename the old datafile)
alter tablespace tablespace_name rename datafile 'old' to 'new' ;
alter tablespace tablespace_name online;
But my problem is that when i query i get the filename different in putty/at server/through a different machine....... so i fear that when i do a rename file "old" as "new" won't that give an error for file does not exists
when i took a controlfile trace it gives me the right name w/o junk characters ... so i thought that recreating controlfile wud do the trick.
If it gives an error, you can use the file number instead of file name
select file#,name from v$datafile
alter database rename file THE FILE# FROM THE PREVIOUS QUERY to THE NEW NAME
That cannot be mistaken
problem is, you've got non-printable characters in your file name. You could try using ctrl+v backspace to list out your files, but will be tedious to find the right combination.
IMHO, I'd just create a new tablespace, move the objects from DATA to it, slap the other DBA on the head, and forget about it.
Thanks for the Laugh!
