Displacement of the LOB segments.
Is there a a way to move LOB segment, keeping the segment of the table? The statement:
ALTER table < tab > move lob (< lob >) store as (tablespace < TBS >)
moves not only the LOB segment, but also table segments, so consumes a lot of resources, needs to rebuild indexes etc.
Thank you.
If you move the lob segment, then the data of the line must change because the lob is in a different place. There is no way around that. The row stores a pointer to LOB. Oracle has decided to implement this in a way that makes all change of rowid (you can't influence that).
So, as I said - it's life.

Calculate the free space of the lob segment / reclaim space?
Friends...
DB: 11 GR 2
OS: Linux
I am trying shrink lob segment and recover the free space between the business segments.
This area in Oracle DB is new to me so try to learn and to shrink the segment.
I went through various metalink doco (386341.1) but not be able to get answers for below...
Issues related to the:
1. how much free space is available in the lob segment?
2 can I assume 'no LOB DATA' as the free space currently and even will be recovered once the segment will be shrunk?
3. no disadvantage of using "ALTER TABLE... SHRINK SPACE.
4. is it true if storage segment is 100 GB as many redo will be generated when trying to alter table... shrink the space?
I'm following the steps below.
1 find Segment name-> sys_lob123
2. find the size of storage - > 100 GB
3. find the size of the LOB data-> 70
4. find the size of the data not LOB-> 30
2. the storage size
Select 'storage' from dba_extents bytes
where nom_segment = 'sys_lob123. '
100 GB
3. the size of the LOB
Select dbms_lob.getlength (col_lob) in the table_lob;
70 GB
4. the size of the LOB data not
100-70 = 30 GB (i.e. #3 - #2)
Thanks in advance and enjoy your time looking into this...
Use DBMS_REDEFINITION to reorganize the LOB segment, it is the best way to retrieve a LOB segment space. Also use the clause "MEANS of COMPRESS" and SECURE LEADER, creating the temp table. There is no reason that you can use the BASIC FILE. It's online process, which means that your app can stay up to... However, make sure that monitor you the database when executing redef, as it can cause conflicts and slow down your application, in which case you must kill the reorg...
If this process is not feasible or overwhelms you, "ALTER TABLE MOVE" is another option.
With 'Displacement of Alter table', you need to rebuild all indexes after you move the LOB segment. Don't forget this is an offline process and your application needs a time out while you do this.

Oracle only allows LOB to be stored in a separate tablespace as the corresponding table provided that they are defined as the LOBs explicitly during the creation of the table, unlike the LOB created by oracle internally because of the column datatype being ANYDATA as in this case.

I am trying to write a PL/SQL procedure that will move all my lob segments in a tablespace again (this is for when a dev environment is created... lots of storage & compaction of the things endure us in the production takes place then!)
I know that the SQL is:
But I want to build these declarations programmatically by querying views user_ or all_. I don't know where to start. If I look in WHERE USER_SEGMENTS, I see segments with names like SYS_LOB0000048001C00017$ $... but I don't know what the table in order to begin to construct the statement "alter table...". ». (In other words, I think I reason that the command ' alter table SYS_LOB0000048001C00017$ $ move lob... ") ("wouldn't be correct).alter table X move lob (name-of-lob) store as tablespace NEWTBS;
Similarly, the SQL will require me to know the name of the lob, I think, and that should be the name of the column in the table. But what view will allow me to extract this information, so I can complete my little building SQL?
Can someone point me in the right direction please?
Oh, and also: in WHERE USER_SEGMENTS, I see that I have «LOBSEGMENT "and types of segment"LOBINDEX"... assuming that the above SQL moves lob segments, how can I move the index business?»I think that you are looking for the table USER_LOBS (or ALL_LOBS or DBA_LOBS). Who has the TABLE_NAME, COLUMN_NAME and nom_segment. So I expect that you are looking for something like (not tested)
FOR x IN (SELECT * FROM user_lobs) LOOP EXECUTE IMMEDIATE 'ALTER TABLE ' || x.table_name || ' MOVE LOB (' || x.segment_name || ') STORE AS TABLESPACE newtbs'; END LOOP;Justin

Truncate table removes the corresponding LOB segment of the table or not?

I have little table with BUSINESS segments, if I pull the table truncated on the table it will purge the LOB segment as well?

It will not erase the LOB segments, but it must release the majority of the allocated space.

Looks like you chunk's size 16 k - Oracle seems to watch only the headers of piece in this code; so you expect the segment number raw blocks to be twice the space 'blocks', as this report if you are using a size of 8 KB block and a fragment of 16 k size.

My database is oracle11g.
I have the table with a CLOB column. Should I keep the LOB segment in the same tablespace or different tablespace?
What are the advantages and disadvantages if we keep the LOB segment in tablespace even?
What are the advantages and disadvantages if we keep the LOB segment in tablespace different?
I would strongly appreciate it if one can provide comments?
ConcerningSB: You may want to reconsider this answer? I'd do it.
Ok does not solve you your answer so I'll. The answer whether if LOB segments must be stored in a different tablespace reports to a number of issues, among them the size of the LOB, he enters the same block perfectly the LOB data not, and if you wondering other than the LOB columns often and only need to access the LOB on rare occasions.
If the LOB is stored out of line, then Oracle does not grant it if it is not needed.
If the LOB is stored in the same tablespace is not relevant. Especially if your data is striped and mirrored as is almost all of the data of these days.

ORA-01691: impossible to extend the confusions of lob segment
Hi all
11.2.0.1 64-bit
on DELL R610
It seemed oracle missed
I am inserting a large table with LOB pictures with 300,000 lines. I expect not to occupy the 40G drive. So I created 3 data files on the USERS tablespace where my diagram
by default. From Oracle or the server or according to which of them is the culprit has the limit of 32G per data file even if they are the two 64-bit. This, I do not understand why? I thought
Only 32-bit OS and Oracle 32bin has limited the maximum size of 32G on each data file? But I found out that now that he has failed on two platform.
So what I've done is create another 2 data files in the USERS tablespace. Then I insert again, but still, I got ORA-1691. I can see that
/oradata/USERS1.dbf a 32G size feel we reach the limit, but I don't understand why he did not move for the next 2 dbfs? who were intact
/oradata/users2.dbf has 2G (original intact)
/oradata/users3.dbf has 2G (original intact)
Is oracle not smart enough to see that there are other available data files?
Please help me shed some light on this confusion
Thank you very much
zxy
Look for error messages in the alert.log
Is your LOB segment in tablespace even?
The data files are set to AUTOEXTEND ON?

Error code 70879003: cannot lock the memory segment.
Hi guys,.
I am trying to build a program runs on a windows CE of touch screen system and tested the majority of individual components to see that they work on the system and they have all been successful, however when I build and try to run the entire program, I am presented with a popup box saying:
App failed. Error code 70897003. Cannot lock the memory segment.
The program then stops completely. I tried to search the web and the forums, but this specific error code is not mentioned anywhere, and the information that I have known impossible to segment errors memory locking has not been very useful and how to solve this problem.
Any suggestion or help would be very appreciated.
OK, so I solved the problem myself, it turns out that's not at all a problem of backend, in my front panel I accidentally overlapped 2 resulting in a being placed inside the other tab controls. Move them so they are not stacked and the problem is solved.
So moral of the story if someone gets this error in the future, check your tab controls are not overlapping / stacked.
