• List of PT TABLES, which contain the digital certificate

  Team,

  We have set up free sign certicate in our environment.

  So, can someone share the list of the PT TABLES, which contain the digital certificate.

  Because, we do not have to refresh the environment and I don't want to lose the digital certificate after the update.

  Thank you

  Take a look at the following.  I did something similar in refresh scripts

  • PSCERTDB - raw certificate data
  • PSCERTDEFN - certificates
  • PSCERTDEFNDEL - certificates delete record.
  • PSCERTISSUER - the issuer of the certificate

  Then, you can be your RETENTION policy. You see for the segments of BUSINESS that they won't go to the TRASH as such. They remain in the LOB segment in order to be able to FLASHBACK. Look at the documentation... I don't know what version you're on, but check this one.

  http://www.Stanford.edu/dept/ITSS/docs/Oracle/10G/AppDev.101/b10796/adlob_ta.htm#1015810

  Check it out...

  RETENTION
  As an alternative to the PCTVERSION parameter, you can specify the RETENTION setting in the clause of the CREATE TABLE or ALTER TABLE statement LOB storage. In doing so, configure the LOB column to store old versions of LOB data for a period of time, rather than using a percentage of the table space. For example:

  CREATE TABLE ContainsLOB_tab (n NUMBER, c CLOB)

  (c) STORE AS SEGNAME of LOB (TABLESPACE lobtbs1 CHUNK 4096

  RETENTION

  NOCACHE LOGGING

  STORAGE (MAXEXTENTS 5)

  *);*

  The RETENTION setting is designed for use with the undo features of the database, such as Flashback Query of Versions. When a LOB column has the property of RETENTION set, old versions of LOB data are kept for the duration specified by the parameter UNDO_RETENTION.

  Noted that in what concerns the RETENTION setting:

  Undo SQL is not enabled for LOB columns as it is with other data types. You must set the property of RETENTION on a column LOB using SQL cancel the LOB data.

  You cannot explicitly set the value of the RETENTION setting. The shelf life of determined by the parameter UNDO_RETENTION LOB versions.

  Use of the RETENTION parameter is supported only in Automatic Undo Management mode. You must configure your table for use with automated cancel before you can configure RETENTION on a LOB column.

  The LOB storage clause can specify RETENTION or PCTVERSION, but not both.

  So your LOB is probably hanging out until you hit the UNDO_RETENTION... even while they will not be deleted but be reused "I think."

• 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.

• Question by adding the LOBs-ORA-06502: PL/SQL: digital error or value

  Hello
  
  I'm using Oracle 11 g.
  
  I have a requirement in which I need to add LOBs and I must insert the LOB in a table column. I am facing problem when the data exceeds certain limits. My program works like the following:
  
  (Please note that my program logic is given below, not the exact program)

  Can you please specify what environment you run this?

  I modified your code as follows

  The code executed successfully until the length has been<= 32767="" i.e="" (="" until="" for="" i="" in="">

  In addition, you must use the function APPEND to concatenate variables clob.

  Please check the maximum size by default for varchar2 or dbms_output in your server since you get the error for just the loop in the range (FOR i IN 1,100).

  And Yes, Siva comments are valid.

• 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.

• How to use the LOB data type?

  There is no LOB = 1 attribute; Please, delete it from your definition ODBC to avoid potential errors.

  LOB support has been added in the major version 11.2.2 TimesTen. So you use 11.2.1 LOB is not available. If you want to use LOB data, then you must upgrade to 11.2.2.

• How to make the sum of hours which is the varchar2 data type in oracle

  Hi my table is like this
  emp_ngtshthrs (empno number (10), nightshifthrs varchar2 (20));
  
  now I want sum employee nightshifthrs how do the sum hours, it's my hours 01:00, 05:00, 08:00, 10:00, 07:00 and 09:00
  I want the sum type varchar2 hours how to do? and I want to display the sum is greater than 24:00

  Well, first of all you have posted your question in the wrong forum. You should have posted your question in the forum SQL and PL/SQL .

  The second problem I see is that you are being too generic when you have your employees enter their night shift hours worked. If you are able, I recommend that you change your table to record hours separately from minutes and make columns of type NUMBER instead of the VARCHAR2() type. Then, you can simply use arithmatic to total the hours and minutes worked.

  If you are locked in your table and cannot change it, you can convert characters to numbers and then perform your basic arithmatic on values. For example:

    1  with tab1 as (
    2  select 10 as empno, '01:00' as nightshifthrs from dual union all
    3  select 10 as empno, '05:00' as nightshifthrs from dual union all
    4  select 10 as empno, '08:00' as nightshifthrs from dual union all
    5  select 10 as empno, '10:00' as nightshifthrs from dual union all
    6  select 10 as empno, '07:00' as nightshifthrs from dual union all
    7  select 10 as empno, '09:00' as nightshifthrs from dual)
    8  select sum(to_number(replace(nightshifthrs,':','.'))) AS hours_worked
    9* from tab1
  SQL> /
  
  HOURS_WORKED
  ------------
            40
  SQL> 
  

  Of course, if your users can and do enter the minutes, then which complicates the example I provided. You will need to convert the decimal minute, sum the amount, then convert the decimal time and add this to your hours. For example:

    1  with tab1 as (
    2  select 10 as empno, '01:15' as nightshifthrs from dual union all
    3  select 10 as empno, '05:00' as nightshifthrs from dual union all
    4  select 10 as empno, '08:30' as nightshifthrs from dual union all
    5  select 10 as empno, '10:00' as nightshifthrs from dual union all
    6  select 10 as empno, '07:45' as nightshifthrs from dual union all
    7  select 10 as empno, '09:00' as nightshifthrs from dual)
    8  select sum(to_number(substr(nightshifthrs,1,2))) + SUM(to_number(SUBSTR(nightshifthrs,4,5)))/60
    9* from tab1
  SQL> /
  
  HOURS_WORKED
  ------------
          41.5
  SQL> 
  

  I hope this helps.

  correct syntax is
  ALTER TABLE.

  MOVE the LOB ()
  STORE AS (tablespace );

  Where is a name of the / columns LOB, not the name of the segment. Moving type LOB data will move its indexes as well.

  Tried on google but have not found any useful information.
  
  Share your ideas.
  
  Thanks in advance.

  The new layout BI Publisher Editor to create reports which have an available interactive output type. The interactive Viewer allows to popup details, tables scrollables, filtering the table, table sorting and filtering through the various components of the report.

  So, if you are interested in providing this kind of functionality, you can design reports with the layout editor.

  Table dropped.
  

  If you want to be able to move the segment to a different tablespace to the table, I guess that's not possible. 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.

• Movement of the LOB Segment

  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:

  alter table X move lob (name-of-lob) store as tablespace NEWTBS;

  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).
  
  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;
