Just noticed MR(media recovery lock ) in our database,further check showd all datafiles had this lock since our database was shutdown abortly but was startup gracefully.

we know we can see lock mode held in session can be analysed using LM column in v$lock.But i confused in seeing LM column it all shows in numbers from 0 to 6.
eg
0,'None(0)',
1,'Null(1)',
2,'Row Share(2)',
3,'Row Exclu(3)',
4,'Share(4)',
5,'Share Row Ex(5)',
6,'Exclusive(6)')
Due to improper documentations of a certain project, I need to drop a DEFAULT tablespace of a newly created instance including it's associated datafiles by using this command:
"DROP TABLESPACE <tablespace name> INCLUDING CONTENTS AND DATAFILES;"
The default tablespace name is QWER (qwer01.dbf) and I added 2 datafiles in it, re: OPD_SML01.dbf & EXYT_SML01.dbf.
Do I have to do it online or offline?
Can we add a datafile mapped to a shared network drive in windows server.

I.
1.Shutdown 2008 server.
2.Copy D: image with GHOST to USB, network.
3.Connect new D, create RAID.
4.Restore image to D.

3.SHUTDOWN NORMAL or (IMMEDIATE)?
4.Copy files *.dbf at OS level from d: to ... USB disk, network.

Table D-7 shows a hierarchical file mapping of a sample OFA-compliant installation with two Oracle home directories and two databases. The database files are distributed across three mount points, /u02, /u03, and /u04. URL....
why three mount points (/u02, /u03, and /u04) for datafiles? don' understant this. isn't it better to store all datafiles in one mountpoint?
I have checked the space of my tablespaces/datafiles in my database. I have 8 GB space left in my database server. I cant add more hard-disk as there is no slot left. We r planning to buy a new server with latest config.
My question is, how can we know upto what size our database can increase and when a datafile need to be added in advance. Sometimes even though datafiles have space left,it shows errors abt extents cannot be extended. We have coalesce the tablespaces and added a new datafile.
I am facing an issue while rebuilding a DR (Physical Standby) site using RMAN.Rman is failing to restore all the datafiles to the stanby site.
There are 403 datafiles that should be restored among which after restoring 50-60 datafiles the channel is abruptly getting terminated.Please note this exercise is not new I have done this many times (once a year after a DR testing) and the same script is being used.The rcv file is as follows

run {

exit

The trace file says "krso_proc_add: Detected dead process 13828326; subsuming V$MANAGED_STANDBY slot

I have also started RMAN debug tracing and the trace is also scanned as it is huge.I have seen the following in the trace error 3015 signalled during compilation..I do not find any specific oracle error to check on .
The only change that happened is that the Primary production server has been moved to a new datacentre and after its move all the connections seems to be working fine.
We have two tablespace xyz_ts & pqr_ts having 167 datafiles . We have to reduce this number of files. These tablespace having 580 GB size .
View 1 Replies View Related would want to check which tables located in which datafiles.
Tried with this command:
select B.FILE_NAME from dba_segments a, dba_data_files b
where a.header_file=b.file_ID and segment_name='TABLE_NAME'
Seems like it only shows 1 datafile. Some tables are large and i suppose it's resided in more than 1 datafile.
what's the difference between having BIG datafile (32GB) vs many small datafiles (4GB) replacing a Big one.
View 3 Replies View RelatedWe have lost some datafiles and some archivelogs. We have backup of whole database taken on Dec 20 and archivelogs until Dec 23.So we dont have 1 day worth of archivelogs which can lead to incomplete recovery.
Now question is do we need to restore all datafiles or only lost datafiles for incomplete recovery since we dont have all archivelogs ? lost datafiles belong to different tablespaces.
Datafiles which are still intact are with current SCN and we restore lost datafiles only and recover unitl our last available archivelog it will have different SCN. Will we be able to open database or we need to resotre whole database for this scenario?

Does it work with copying datafiles from 10g2 to 11g2? I want to move one huge tablespace (which contains one table) from 10g2 to 11g2, what is the best method to do that?
Basically , we have a large index tablespace , whose data files already spans multiple mount points , and has been extended with a new data file on a wrong mount point by mistake , Can we relocate this last datafile extension , to a different mount point while the DB is online ? Is there any special consideration for index datafiles (If such classification is correct ) or is it just like any other Oracle non-system datafile ?
What will be the effect on the normal data tables which are using this index if they are being accessed during the exercise? This is a 2 node Oracle 9i 9.2.0.8.0 RAC on Veritas Cluster .

11.2.0.2 on Solaris..I have such a large post on a very basic space calculation.
We have several tablespaces starting with WLMCS in our DB..I just wanted to calculate the total space consumed in the disk by all these tablespace combined .When I queried DBA_DATA_FILES.MAXBYTES and DBA_DATA_FILES.USER_BYTES , I've noticed that ,
When AUTOEXTEND is NO: MAXBYTES is 0 for these datafiles . But USER_BYTES won't be 0 for these files
When AUTOEXTEND is YES: MAXBYTES will be a non-zero value for these datafiles . USER_BYTES won't be 0 either for these files-- Not including datafile names for better readability.
SYS > select tablespace_name, maxbytes/1024/1024, user_bytes/1024/1024, autoextensible from dba_data_files where tablespace_name like 'WLMCS%';
TABLESPACE_NAME MAXBYTES/1024/1024 USER_BYTES/1024/1024 AUT

[code]....
11 rows selected.To calculate the space consumed , I made 2 assumptions.Are the below 2 assumptions right?
Assumption 1. Whenever MAXBYTES = 0 , USER_BYTES should be considered for the space calculation.
Assumption 2. Whenever you have non-zero values for both MAXBYTES and USER_BYTES , MAXBYTES should be considered for the space calcuation.I did the calculation (adding up of) based on the above assumptions. Is this calcualtion Correct ?
