CLOB column resize

Hi,
Below question is for oracle 11g database on RHEL.
we are having a CLOB column of 8K. Now the developer is asking to get that increase to 32k how can i make that?
As i know we cannot change "chunk" size once after it is created. I thought we need to recreate a new table with chunk 32k and then export/import the data from old table and drop that old table.
But, the point where i'm struck is ,
the DB_BLOCK_SIZE is 8k. So, can we create a new table with 32k chunk size. Does it conflict?
If thats not possible, i thought an alternative of recreating a tablespace with 32k. I heard that, we can create new tablespace with different db_block_size.. i'm not sure if i'm right? and if you don't mind can you just explain me the lob in-line and out-line.. i read the documents but, i didn't get that well
Can you please suggest me the better way and correct me if i'm wrong..

How to alter LOB storage definition.
You may use the following to alter the table and the associated LOB allowing for more extents:
alter table owner.table_name
modify LOB(lob_column_name)
(storage (next 100M MAXEXTENTS 1000));
Example:
User is getting the following error:
APP-FND-00565: The export failed in APP_EXPORT.DUMP_DATA
PL/SQL ERROR: ORA-01691: unable to extend lob segment APPLSYS.SYS_LOB0000033586C00004$$ by 311075 in tablespace APPLSYSD
Looking at tablespace APPLSYSD I can see that it does have room to extent at datafile level for another 800 MB. And TEMP has plenty of room as well.
Using the SQL provided in this page: Looking at the LOB:
SYS_LOB0000033586C00004$$
It looks like Column FILE_DATA of datatype LOBSEGMENT in table APPLSYS.FND_LOBS has grown to be 5 GB in size and was trying to extent itself grabbing another 2.3 GB (NEXT_EXTENT is 2548301824) which of course it could not do, I modified it so it can extent only by another 100 MB.
SQL> alter table APPLSYS.FND_LOBS modify lob (FILE_DATA)
(storage (maxextents 1000 next 100M));
Table altered.

I know there was a problem in 6i where you would get a crash if your query returned more than {Max Length} characters of the field representing the CLOB column.

Error reading data from CLOB column into VARCHAR2 variable

Hi all,
Am hitting an issue retrieving data > 8K (minus 1) stored in a CLOB column into a VARCHAR2 variable in PL/SQL...
The "problem to be solved" here is storing DDL, in this case a "CREATE VIEW" statement, that is longer than 8K for later retrieval (and execution) using dynamic SQL. Given that the EXECUTE IMMEDIATE statement can take a VARCHAR2 variable (up to 32K(-1)), this should suffice for our needs, however, it seems that somewhere in the process of converting this VARCHAR2 text to a CLOB for storage, and then retrieving the CLOB and attempting to put it back into a VARCHAR2 variable, it is throwing a standard ORA-06502 exception ("PL/SQL: numeric or value error"). Consider the following code:
set serveroutput on
drop table test1;
create table test1(col1 CLOB);
declare
cursor c1 is select col1 from test1;
myvar VARCHAR2(32000);
begin
myvar := '';
for i in 1..8192 loop
myvar := myvar || 'a';
end loop;
INSERT INTO test1 (col1) VALUES (myvar);
for arec in c1 loop
begin
myvar := arec.col1;
dbms_output.put_line('Read data of length ' || length(myvar));
exception when others then
dbms_output.put_line('Error reading data: ' || sqlerrm);
end;
end loop;
end;
If you change the loop upper bound to 8191, all works fine. I'm guessing this might have something to do with the database character set -- we've recently converted our databases over to UTF-8, for Internationalizion support, and that seems to have changed underlying assumptions regarding character processing...?
As far as the dynamic SQL issue goes, we can probably use the DBMS_SQL interface instead, with it's EXECUTE procedure that takes a PL/SQL array of varchar2(32K) - the only issue there is reading the data from the CLOB column, and then breaking that data into an array but that doesn't seem insurmountable. But this same basic issue (when a 9K text block, let's say, turns into a >32K block after being CLOBberred) seems to comes up in other text-processing situations also, so any ideas for how to resolve would be much appreciated.
Thanks for any tips/hints/ideas...

For those curious about this, here's the word from Oracle support (courtesy of Metalinks):
RESEARCH
========
Test the issue for different DB version and different characterset.
--Testing the following PL/SQL blocks by using direct assignment method(myvar := arec.col1;) on
different database version and different characterset.
SQL>create table test1(col1 CLOB);
--Inserting four CLOB data into test1.
declare
myvar VARCHAR2(32767);
begin
myvar := RPAD('a',4000);
INSERT INTO test1 (col1) VALUES (myvar);
myvar := RPAD('a',8191);
INSERT INTO test1 (col1) VALUES (myvar);
myvar := RPAD('b',8192);
INSERT INTO test1 (col1) VALUES (myvar);
myvar := RPAD('c',32767);
INSERT INTO test1 (col1) VALUES (myvar);
commit;
end;
--Testing the direct assignment method.
declare
cursor c1 is select col1, length(col1) len1 from test1;
myvar VARCHAR2(32767);
begin
for arec in c1 loop
myvar := arec.col1;
--DBMS_LOB.READ(arec.col1, arec.len1, 1, myvar);
dbms_output.put_line('Read data of length: ' || length(myvar));
end loop;
end;
The following are the summary of the test results:
===================================
1. If the database characterset is WE8ISO8859P1, then the above direct assignment
method(myvar := arec.col1;) works for database version 9i/10g/11g without any
errors.
2. If the database characterset is UTF8 or AL32UTF8, then the above direct assignment method(myvar := arec.col1;) will generate the "ORA-06502:
PL/SQL: numeric or value error" when the length of the CLOB data is greater
than 8191(=8K-1). The same error can be reproduced across all database versions
9i/10g/11g.
3. Using DBMS_LOB.READ(arec.col1, arec.len1, 1, myvar) method to read CLOB data into a VARCHAR2 variable works for both WE8ISO8859P1 and UTF8
characterset and for all database versions.
So - it seems as I'd surmised, UTF8 changes the way VARCHAR2 and CLOB data is handled. Not too surprising, I suppose - may you all be lucky enough to be able to stay away from this sort of issue. But - the DBMS_LOB.READ workaround is certainly sufficient for the text processing situations we find ourselves in currently.

Split CLOB column to improve performance

Hi All,
We have a transactional table which has 3 columns and one among those is CLOB which holds XML data.Inserts are coming at 35K/hr to this table and data will be deleted as soon as job is completed. So anytime the total records in this table will be less than 1000.
The XML data contains binary info of images and the size of each XML file ranges any where between 200KB to 600KB and the elapsed time for each insert varies from 1 to 2 secs depending upon the concurrency. As we need to achieve 125K/hour soon we were planning to do few modifications on table level.
1. Increase the CHUNK size from 8KB to 32KB.
2. Disabling logging for table,clob and index.
3. Disable flashback for database.
4. Move the table to a non default blocksize of 32KB. Default is 8KB
5. Increase the SDU value.
6. Split the XML data and store it on multiple CLOB columns.
We don't do any update to this table. Its only INSERT,SELECT and DELETE operations.
The major wait events I'm seeing during the insert is
1. direct path read
2. direct path write
3. flashback logfile sync
4. SQL*Net more data from client
5. Buffer busy wait
My doubt over here is ,
1. If I allocate a 2G memory for the non default block size and change the clob to CACHE, will my other objects in buffer_cache gets affected or gets aged out fast?
2. And moving this table to a SECUREFILE from BASICFILE will help?
3. Splitting the XML data to insert into different columns in the same table will give a performance boost?
Oracle EE 11.2.0.1,ASM
Thanks,
Arun

Thanks to all for the replies
@Sybrand
Please answer first whether the column is stored in a separate lobsegment.
No. Table,Index,LOB,LOB index uses the same TS. I missed adding this point( moving to separate TS) as part of table modifications.
@Hemant
There's a famous paper / blog post about CLOBs and Database Flashback. If I find it, I'll post the URL.
Is this the one you are referring to
http://laimisnd.wordpress.com/2011/03/25/lobs-and-flashback-database-performance/
By moving the CLOB column to different block size , I will test the performance improvement it gives and will share the results.
We dont need any data from this table. XML file contains details about finger prints and once the application server completes the job , XML data is deleted from this table.
So no need of backup/recovery operations for this table. Client will be able to replay the transactions if any problem occurs.
@Billy
We are not performing XML parsing on DB side. Gets the XML data from client -> insert into table -> client selects from table -> Upon successful completion of the Job from client ,XML data gets deleted.
Regarding binding of LOB from client side, will check on that side also to reduce round trips.
By changing the blocksize, I can keep db_32K_cache_size=2G and keep this table in CACHE. If I directly put my table to CACHE, it will age out all other operation from buffer which makes things worse for us.
This insert is part of transaction( Registration of a finger print) and this is the only statement taking time as of now compared to other statements in the transaction.
Thanks,
Arun

How to read/write .CSV file into CLOB column in a table of Oracle 10g

I have a requirement which is nothing but a table has two column
create table emp_data (empid number, report clob)
Here REPORT column is CLOB data type which used to load the data from the .csv file.
The requirement here is
1) How to load data from .CSV file into CLOB column along with empid using DBMS_lob utility
2) How to read report columns which should return all the columns present in the .CSV file (dynamically because every csv file may have different number of columns) along with the primariy key empid).
eg: empid report_field1 report_field2
1 x y
Any help would be appreciated.

If I understand you right, you want each row in your table to contain an emp_id and the complete text of a multi-record .csv file.
It's not clear how you relate emp_id to the appropriate file to be read. Is the emp_id stored in the csv file?
To read the file, you can use functions from [UTL_FILE|http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/u_file.htm#BABGGEDF] (as long as the file is in a directory accessible to the Oracle server):
declare
    lt_report_clob CLOB;
    l_max_line_length integer := 1024;   -- set as high as the longest line in your file
    l_infile UTL_FILE.file_type;
    l_buffer varchar2(1024);
    l_emp_id report_table.emp_id%type := 123; -- not clear where emp_id comes from
    l_filename varchar2(200) := 'my_file_name.csv';   -- get this from somewhere
begin
   -- open the file; we assume an Oracle directory has already been created
    l_infile := utl_file.fopen('CSV_DIRECTORY', l_filename, 'r', l_max_line_length);
    -- initialise the empty clob
    dbms_lob.createtemporary(lt_report_clob, TRUE, DBMS_LOB.session);
    loop
      begin
         utl_file.get_line(l_infile, l_buffer);
         dbms_lob.append(lt_report_clob, l_buffer);
      exception
         when no_data_found then
             exit;
      end;
    end loop;
    insert into report_table (emp_id, report)
    values (l_emp_id, lt_report_clob);
    -- free the temporary lob
    dbms_lob.freetemporary(lt_report_clob);
   -- close the file
   UTL_FILE.fclose(l_infile);
end;This simple line-by-line approach is easy to understand, and gives you an opportunity (if you want) to take each line in the file and transform it (for example, you could transform it into a nested table, or into XML). However it can be rather slow if there are many records in the csv file - the lob_append operation is not particularly efficient. I was able to improve the efficiency by caching the lines in a VARCHAR2 up to a maximum cache size, and only then appending to the LOB - see [three posts on my blog|http://preferisco.blogspot.com/search/label/lob].
There is at least one other possibility:
- you could use [DBMS_LOB.loadclobfromfile|http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_lob.htm#i998978]. I've not tried this before myself, but I think the procedure is described [here in the 9i docs|http://download.oracle.com/docs/cd/B10501_01/appdev.920/a96591/adl12bfl.htm#879711]. This is likely to be faster than UTL_FILE (because it is all happening in the underlying DBMS_LOB package, possibly in a native way).
That's all for now. I haven't yet answered your question on how to report data back out of the CLOB. I would like to know how you associate employees with files; what happens if there is > 1 file per employee, etc.
HTH
Regards Nigel

And i want to retrieve the values of tag
<ChannelID> and <v6:VID>
can somebody help, i have tried with extractvalue but not able to get the values

I have used the below two queries but not able to get the expected results. Both queries result into no values.
select xmltype(MED_REQ_PAYLOAD).extract('//ClientDetails/Org','xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" || xmlns="http://www.abc.com/gcgi/shared/system/header"').getStringValue() from ESB_OUTPUT_TEMP where SOAPACTION = '/SvcImpl/bank/alerts/v6_0_0_0/SOAPEndpoint/AlertsService.serviceagent/OpEndpointHTTP/AlertDeleteInq'
select EXTRACTVALUE(xmltype(MED_REQ_PAYLOAD),'/RqHeader/) from ESB_OUTPUT_TEMP where SOAPACTION = '/SvcImpl/bank/SOAPEndpoint/AlertsService.serviceagent/OpEndpointHTTP/AlertDeleteInq'
Well, for starters, both queries are syntactically wrong :
- non terminated string
- incorrect namespace mapping declaration
- unknown XMLType method "getStringValue()"
Secondly, all those functions are deprecated now.
Here's an up-to-date example using XMLTable. It will retrieve the two tag values you mentioned :
SQL> select x.*
2 from esb_output_temp t
3     , xmltable(
4         xmlnamespaces(
5           'http://schemas.xmlsoap.org/soap/envelope/' as "soap"
6         , 'http://www.abc.com/gcgi/shared/system/header' as "head"
7         , 'http://www.abc.com/gcgi/services/v6_0_0_0' as "v6"
8         )
9       , '/soap:Envelope'
10         passing xmlparse(document t.med_req_payload)
11         columns ChannelID varchar2(10) path 'soap:Header/head:RqHeader/head:ClientDetails/head:ChannelID'
12               , VID        varchar2(30) path 'soap:Body/v6:AlertDeleteInqRq/v6:Base/v6:VID'
13       ) x
14 ;
CHANNELID VID
HBK        20071209013112
You may also want to store XML in XMLType columns for both performance and storage optimizations.

See XML updating functions : http://docs.oracle.com/cd/E11882_01/appdev.112/e23094/xdb04cre.htm#i1032611
For example :
UPDATE my_table t
SET t.my_clob =
      XMLSerialize(document
        insertChildXML(
          XMLParse(document t.my_clob)
        , '/Activity/Spawned'
        , 'Activity'
        , XMLElement("Activity", 'Some GUID')
WHERE ...
;Although it works, there's overhead introduced by parsing the CLOB, then serializing again.
Is there any chance you can change the CLOB to SECUREFILE binary XMLType storage instead?
You would then be able to benefit from optimized piecewise update of the XML and improved storage.

Limitation for CLOB columns? - ORA-01704: string literal too long

Hello!
I'm trying to update a CLOB column with more than 35000 characteres, but I get "ORA-01704: string literal too long".
The code:
declare
l_clob clob;

returning test into l_clob;
dbms_lob.write( l_clob, length('A...here 35000xA...A'), 1,'A...here 35000xA...A');
end;
Is there any limitation for CLOB columns?
Thanks for help.

Getting an error while selecting from table having CLOB column.

Hi All,
I have below table created in My oracle database version Oracle Database 11g Enterprise Edition Release 11.2.0.1.0.
CREATE TABLE my_clob -- Dummy table created
(DataBody CLOB);
Current Database Character set - WE8MSWIN1250.
On the front end of my application, I have one form through which I can save/edit data in the above table. If I'm creating one new entry in the above table then it first check with existing record to avoid the duplicate entry and the this point application create the below select statement on the above table and return the error "ORA-00932: inconsistent data types: expected - got CLOB".
I can not change the sql statement.
SELECT * FROM my_clob WHERE databody IS NULL OR databody ='';
Even when I run the same statement on my DB server I’m getting the same error. Shown below
SQL> SELECT * FROM my_clob WHERE databody IS NULL OR databody ='';
SELECT * FROM my_clob WHERE databody IS NULL OR databody =''
ERROR at line 1:

Is there anything with OraOLEDB which causing this error? Please help me out to get rid of this error.
Thanks,

You cannot compare directly a CLOB column with a VARCHAR2 column. In your case you don't need to do such comparison because Oracle consider zero length strings as null values:
SQL> create table my_clob(data int, databody clob);
Table created.
SQL> insert into my_clob values(1, null);
1 row created.
SQL> insert into my_clob values(2, '');
1 row created.

Reading Xml file from clob column in the staging table

Hi,
I am trying to poll the staging table with the database adapter which has CLOB column type containing XML file. How do I extract the XML file from CLOB and map the fields to the another variable with definite schema.
Thanks,

1) when you create DBAdapter on a table which having the clob column watch closely the created xsd for the DBAdapter the clob cloumn element should be a String data type
2) create xsd for Xml File and create variable for the xsd element
3) use ora:parseEscapedXML("yourDBAdapterclobElement") to XmlFileVarilable

How do you select a clob column in an SQL query report?

I must be missing something fundamental as there is practically no help on this on the forum.
All I want to do is ...
select numcol,aclob_col from table
in an SQL Query report.
Sounds easy??? I get no data appearing in the clob column. Doesn't work in SQL Workshop either. What's the catch??
regards
Paul P

Paul,
It works when I try it. What version of Application Express, what is the table DDL, the exact query, and how much data is in the clob columns?

Setting Line Terminator for a CLOB column by script

Hello Everyone,
I have a CLOB column in my table that receives external data (more than 400 sources).
The GUI application displays it in different ways because of the multiple incoming Line Terminators.
Here is the weird thing:
In SQL developper 3.1.06. In the Preferences->Environment I selected as Line Terminator: Carriage Return and Line Fe(Windows)
Once I committed the changes the data was properly displayed in the application (apparently was also re-coded).
My Question is:
How can I setup this property on the column or table to fix the issue??
(I'm looking for a DDL script or something alike).
Thanks in advance.

If that's the case, What is the SQL DEveloper doing then??
I tested and looks like is a global parameter, not sure if works only for the table. (That what I need).
If is possible to setup this feature from the GUI it should be a way to do it running a Script.
Right????No.
Tables don't have any concept of "lines".
CLOB's don't have any concept of "lines".
"lines" only exist in the context of the data you are providing, but that's not of concern to the database.
So it looks like, what SQL Developer is doing (I assume as I don't use it), is to have a setting such that when it comes to display character data from VARCHAR2's or CLOB's it determines if there are CR/LF or just LF characters (as per the setting) and then uses those as line terminators for displaying the data in it's own interface. Thus it sounds like an interface specific setting, or to put it bluntly, it's something that is a part of SQL Developer to control how it displays things.
Have you tried querying back the raw version of the data from the database to see that it still has the CR/LF characters in it? It should.
I think you'll find the setting is a "display" setting, not a "alter my data" setting.
