Backup validate check logical

hi,
An mssql dba asked me if oracle could do logical/physical corruption checking when performing backups. Im aware of BACKUP VALIDATE CHECK LOGICAL.
However, it doesn't create any backup. It just checks for corruption. If I remember, you can run BACKUP CHECK LOGICAL which will actually create the backup and check logical at the same time, but my question is...
Why would you not want one or both of these as standard? I get it that there's overhead, more so for VALIDATE, but would you really want backups that contain corruption? Even if you keep 30 days worth of backups, you could realise after 40 days that you had corruption, and not be able to restore.
Or is the reasoning behind not making it default, that you've got 'enough' backups that even if a datafile gets logical/physical corruption, you're bound to discover it before your backups become obsolete, and that it's then not worth the overhead of making it default?

You can have the settings with SET MAXCORRUPT FOR DATAFILE.
By default a checksum is calculated for every block read from a datafile and stored in the backup or image copy. If you use the NOCHECKSUM option, then checksums are not calculated. If the block already contains a checksum, however, then the checksum is validated and stored in the backup. If the validation fails, then the block is marked corrupt in the backup.
The SET MAXCORRUPT FOR DATAFILE command sets how many corrupt blocks in a datafile that BACKUP will tolerate. If a datafile has more corrupt blocks than specified by the MAXCORRUPT parameter, the command terminates. If you specify the CHECK LOGICAL option, RMAN checks for logical and physical corruption.
By default, the BACKUP command terminates when it cannot access a datafile. You can specify parameters to prevent termination, as listed in the following table.
If you specify the option ... Then RMAN skips...
SKIP INACCESSIBLE Inaccessible datafiles. A datafile is only considered inaccessible if it cannot be read. Some offline datafiles can still be read because they exist on disk. Others have been deleted or moved and so cannot be read, making them inaccessible.
SKIP OFFLINE Offline datafiles.
SKIP READONLY Datafiles in read-only tablespaces.

Backup validate check logical database

What is exactly the following RMAN command do? I want to know Is it doing a full backup or not?
rman> backup validate check logical database' . Kindly help me.

RMAN does not physically backup the database with this command. But it reads all blocks and checks for corruptions.
If it finds corrupted blocks it will place the information about the corruption into a view:
v$database_block_corruption;
Now we can tell RMAN to recover all the blocks which it has found as being corrupt:
RMAN> blockrecover corruption list; # (all blocks from v$database_block_corruption)
Use below link for reference.

BACKUP VALIDATE vs VALIDATE in checking logical/physical corruption

Hello all,
I am checking if our 10gR2 database has any physical or logical corruption. I have read in some places where they state that VALIDATE command is enough to check database for physical corruption. Our database was never backed up by RMAN specifically before. Are any configuration settings needed for running BACKUP VALIDATE command? The reason I am asking is because just the VALIDATE command returns an error and BACKUP VALIDATE command runs without error but it is not showing the
"File Status Marked Corrupt Empty Blocks Blocks Examined High SCN" lines.
I used the command in two different formats and both do not show individual data file statuses:
RMAN> run {
CONFIGURE DEFAULT DEVICE TYPE TO DISK;
CONFIGURE DEVICE TYPE DISK PARALLELISM 10 BACKUP TYPE TO BACKUPSET;
BACKUP VALIDATE CHECK LOGICAL DATABASE FILESPERSET=10;
RMAN> BACKUP VALIDATE CHECK LOGICAL DATABASE
RMAN> VALIDATE DATABASE;

However on a different database already being backed up by RMAN daily, BACKUP VALIDATE output shows list of datafiles and STATUS = OK as below:
List of Datafiles

File Status Marked Corrupt Empty Blocks Blocks Examined High SCN
How can we check every individual datafile status. Appreciate your responses. Thanks.

Hi,
After you have run:
BACKUP VALIDATE CHECK LOGICAL DATABASE You can use sqlplus and run:
select * from v$database_block_corruption.The output will tell you which block in which datafile is corrupt.

Backup validate command

I have few questions to clear my confusion.Can anyone please clarify it.
1)Does Backup validate check logical database plus archivelog all takes same time as real backup?
2)does database needs to be in archivelog mode?
3)can this validate command run mount state?
Thanks

Here is a simple illustration for you;

Backup blocks all check logical validate database

Hello,
From Metalink : How To Use RMAN To Check For Logical & Physical Database Corruption [ID 283053.1]
The following example shows how to validate all datafiles:
run {
allocate channel d1 type disk;
backup blocks all check logical validate database;
release channel d1;
Does this following command just check for corruption , or is it actually trying to backup the datafiles to the disks ?
Thanks

Hello,
The BACKUP VALIDATE statement is used for checking Block Corruption not for running a Backup.
You'll have more detail on the following links:

Hope this help.

Best practise: validate/check backups are good

Hello all
Oracle 10g on Linux, Veritas NetBackup for Oracle - Release 6.5
How do you ensure that backups taken with rman are good?
Some ideas to discuss:
- restore/recover backups to a clone database after backup
- using command "validate backupset" (question remains: how to determine last written backupsets?)
see also Metalink 466221.1
Thanks Casi

RMAN has this capability built-in. Very simply:
BACKUP VALIDATE DATABASE;but there are numerous variations many of which I have captured here:
http://www.morganslibrary.org/reference/rman.html
at page bottom under the heading "Validate"
Equally important keep you eye on:
gv$backup_corruption
gv$copy_corruption
and
gv$database_block_corruption

Restore Validate Database vs Backup Validate Database

Hi,
I want to add the following sentence after taking the backup using following command (backup as compressed backupset database plus archivelog;)
restore database validate;
or
backup validate database;
which one is best?

It depends on what you are trying to accomplish, as per documentation:
http://download.oracle.com/docs/cd/B19306_01/backup.102/b14194/rcmsynta009.htm#sthref141BACKUP .. VALIDATE: Causes RMAN to scan the specified files and verify their contents, testing whether this file can be backed up. RMAN creates no output files. Use this command periodically to check for physical and logical errors in database files.
http://download.oracle.com/docs/cd/B19306_01/backup.102/b14194/rcmsynta051.htm#sthref796
RESTORE... VALIDATE causes RMAN to select existing backups that it would use to perform a RESTORE operation, and scan them all to ensure that they are present and free of corruption.>
Guessing what you're trying to do, I recommend:
backup check logical as compressed backupset database plus archivelog;
restore validate database;
CHECK LOGICAL. Tests data and index blocks that pass physical corruption checks for logical corruption, for example, corruption of a row piece or index entry. If RMAN finds logical corruption, then it logs the block in the alert.log and server session trace file. HTH

PERFORMING A TEST BACKUP (VALIDATE BACKUP) USING RMAN

제품 : RMAN
작성날짜 : 2002-05-30
PERFORMING A TEST BACKUP (VALIDATE BACKUP) USING RMAN
=====================================================
PURPOSE
RMAN을 이용하여 Test Backup을 수행하기 위한 정보를 제공한다.
EXPLANATION
8.1.7 부터 RMAN에서 BACKUP command에 VALIDATE keyword를 사용할 수 있게 되었다
이 명령의 수행은 다음과 같은 작업을 수행한다.
- Datafile의 physical and logical corruption을 check한다.
- 모든 database file들이 존재하는지, 그리고 올바른 위치에 있는지를 검증한다.
RMAN은 실제적으로 backupset을 생성하지 않는다 그러나 그것들이 backup될 수
있는지 없는지를 결정하기 위해서 기술된 file들을 scan한다.
BACKUP VALIDATE 는 backup job을 수행시 수행되는 것을 제외하고는
RESTORE VALIDATE와 거의 비슷하다.
EXAMPLE
아래와 같은 command들을 수행하여 backup하고자 하는 database file과 archived redo
log들이 실제로 backup될 수 있는지를 검증할 수 있다.
RUN {
ALLOCATE CHANNEL ch1 TYPE 'sbt_tape';
BACKUP VALIDATE
DATABASE
ARCHIVELOG ALL;
Note: MAXCORRUPT or PROXY parameter는 VALIDATE option과 함께 사용할 수 없다.

RMAN Parallel Backup Validate

Hi,
OS= Solaris 10
Database = 10gR2
I am using following script to validate the physical and logical corruption in the database through RMAN:
rman target /
RMAN> RUN {
CONFIGURE DEVICE TYPE DISK PARALLELISM 8;
ALLOCATE CHANNEL d1 DEVICE TYPE DISK;
ALLOCATE CHANNEL d2 DEVICE TYPE DISK;
ALLOCATE CHANNEL d3 DEVICE TYPE DISK;
ALLOCATE CHANNEL d4 DEVICE TYPE DISK;
BACKUP VALIDATE DATABASE;
RELEASE CHANNEL;
My machine has 4 CPUs.
I just want to verify that will the above RMAN script open up 4 channels in parallel and validate the database?

DB Version: 10gR2, 11GR2
Is the following command meant to check block corruption in the original datafile or is it meant to check if the rman backup of this file is fit for restore?
backup validate datafile 1;The equivalent of the above command in 11g is
validate datafile 1;Right?

Both are true.
The VALIDATE command is to check for corrupt blocks and missing files, or to determine whether a backup set can be restored.
If the backup validation discovers corrupt blocks, then RMAN updates the V$DATABASE_BLOCK_CORRUPTION view with rows describing the corruptions. After a corrupt block is repaired, the row identifying this block is deleted from the view.
Oracle 11g,
The options in the VALIDATE command are semantically equivalent to options in the BACKUP VALIDATE command.

Please validate my logic performance point of view:

Please validate my logic performance point of view:
logic I wrote :
   LOOP AT i_mara INTO wa_mara.
*-----For material description, go to makt table.
      SELECT SINGLE maktx
        FROM makt
        INTO l_maktx
       WHERE matnr = lwa_mara-matnr
         AND SPRAS = 'E'.
      IF sy-subrc = 0.
        wa_mara-MAKTX = l_maktx.
      ENDIF.        " IF sy-subrc = 0.
*-----For Recurring Inspection, go to marc table.
      SELECT prfrq
        FROM marc
        INTO l_prfrq
        UP TO 1 ROWS
       WHERE matnr = lwa_mara-matnr.
      ENDSELECT.
      IF sy-subrc = 0.
        wa_mara-prfrq = l_prfrq.
      ENDIF.          " IF sy-subrc = 0.
      MODIFY TABLE i_mara FROM wa_mara
             TRANSPORTING maktx.
      CLEAR : wa_mara.
   ENDLOOP.   " LOOP AT i_mara INTO wa_mara.
Or is it better below : ?
To SELECT all the maktx values from makt and all prfrq values from marc
in two internal tables and
Loop at i_mara.
LOOP at all maktx itab
and pass corresponding maktx values into i_mara table
and pass corresponding prfrq values into i_mara table
ENDLOOP.
OR
is there any better performance logic you suggest ?
THANKS IN ADVANCE.

ok this is very funny so if someone gets a good way to code he should wait till he gets 1198 points till he write a performance wiki
so that means ppl who has high SDN points only can write wiki
for your information wiki definition is
[http://en.wikipedia.org/wiki/Wiki |http://en.wikipedia.org/wiki/Wiki]
its all about contribution and sharing.
did you try that code on a production or a Quality server. If you did you wont say that coz the results i have shown in that blog is what i my self tested on a Quality system of our client.
and for your information i did my internship at a SAP AFS consultancy firm and i created the account at that time. I have joined that company and now working as a developer over there.
if you have worked on a client system development on SD and MM you will know that most of the time
we use header and item tables like
likp,lips
vbak,vbap
vbrk,vbrp
most of the time we come across nested loops with smiler kind of condition.
in this Q he has MATNR as reference.
if you see it properly you can see both tables are sorted.
and the select statement is for all entries.
for your information there can be a delivery document item with out a header if you are aware of DB concepts in that case there will be a foreign key error.
ok lets think about a situation like that even in that case if there ant any header data then simply the client wont request for that record.( you would know if you have worked with clients )
last but not least i dont care about my points rate at SDN i just wanted to share what i know coz anyway i have a very good job here. dont try to put down ppl just because they are new.
Thomas Zloch : i never told its my code i saw it some where then i checked and i bogged it so that i can get it when i want and i saw it in se30 ( its not se38 ) but i know most of ABAP developers dont check it much so i just wanted to help.
Rui Pedro Dantas   : ya your correct we dont need to use it most of the time since sorted table is easy but there are programs which works with bulky data load we can use it in places like that. Thanks for talking the truth

sorry if i said anything to hurt anyone.

Parameter ' check logical ' question

Hello,
in the rman backup and recovery reference 10gR2, it says for the check logical parameter for backup:
If the initialization parameter DB_BLOCK_CHECKSUM=TRUE, and if MAXCORRUPT and NOCHECKSUM are not set, then specifying CHECK LOGICAL detects all types of corruption that are possible to detect.
But there is no description for the alternative of DB_BLOCK_CHECKSUM=FALSE.
Now Ct. wants to know: What does check logical check if this parameter is not set to true?
Ct. wants to check all kinds of corruption which is checkable by rman.
regards
Ulli

Without the CHECK LOGICAL clause, RMAN will perform 2 types of validation in the cache layer of the datablock: block checksum and head/tail verification. When you add CHECK LOGCIAL clause, we perform additional checks in the transaction and data layer of the block which will add to the the processing time.
However, a delay of 3.2 times seems a bit of higher side. You might want to check for the CPU/IO utilization on the machine. If you have idle CPU, you may consider adding more channels. Look out for v$backup_async_io.LONG_WAITS, if the number is high, IO is slow.
It is also possible that due to the additional checks, RMAN is not able to fill the output buffer as fast as earlier. In that case, consider increasing multiplexing (FILESPERSET / MAXOPENFILE)

How to set value from LOV only as a default reference not enforce validate check?

In jdev 11.1.2.3,
By creating List of Value(LOV) for an attribute of a VO, I can get default value for the current VO's attribute from the lookup table, but it will also enforce a validate check for that value.
If I input a value which is not in the lookup table, then errors will raised.
Now I hope I can get default value from LOV, and can also input some new value (and this new value can be insert into the lookup table by a database trigger) for the attribute/field without failure to pass the check.
Any one can help?
Thanks!

Hi, Arun
Your suggestion let me get to know how to create a new record in the customeActions facet of inputComboBoxListOfValues, which I donot know before. It's great. and thank you very much.
However, my current issue is a different requirement, let me describe it clearly as:
I have a formlayout to input a field value which can be from a lookup table, or if this value is not in the lookup table then it can also be input without raising value validation check failure.and this new value can be added to the lookup table at the same time.
for example, there is a FK attribute deptno in the EMP table, in a form for editing EMP attributes, user can input deptno value which is already in the DEPT lookup table by selecting from a LOV. also can input some new value which cannot be selected from the LOV, and this new deptno value will be posted to database both in EMP and DEPT table.
The issue is, after create a LOV for deptno attribute in EMP VO, there will be a enforced value validation check, so new values cannot be input in EMP unless it is input into DEPT first.
(http://docs.oracle.com/cd/E37975_01/web.111240/e16182/lists.htm#BABBJFBB)
List of values are designed to return valid values only. As a result, validation rules defined on data source view object attributes will be suppressed.
My question is: how to disable this enforced value validation for a LOV-enabled field?
(There is other means to ensure user will input valid value for this field, for example ask him to double input.)
Thanks again!

Epub with fix layout and the apple validate check... :-(

Hi
I made a fix layouted epub. So good so far. The most platforms still accept it, except apple (like almost). After using the EPUB Validator (beta) I get an result which I cannot fix.
f.e:
in OEBPS/content.opf
element "dc:date" not allowed here; expected the element end-tag or element "dc:contributor", "dc:coverage", "dc:creator", "dc:description", "dc:format", "dc:identifier", "dc:language", "dc:publisher", "dc:relation", "dc:rights", "dc:source", "dc:subject", "dc:title", "dc:type", "link" or "meta"
or here
OEBPS/Text/79607-9783941484870-ebook-1.xhtml
Obsolete or irregular DOCTYPE statement. External DTD entities are not allowed. Use '<!DOCTYPE html>' instead.
that error repeats through all the xhtml files
at the end:

Validated using EpubCheck version 3.0.1.
for me it looks for a misstake into the export programm of ID.
What can I do? I'm using ID CC 2014 actual version
Thanks and regards from Germany.

Hi Steve,
thanks for this information. In the meantime i fix my problems by myself. The export of Indesing makes no mistakes. My problem was that I start the ebooks with Sigil after export. And Sigils rewrite some codes. That brought the errors by the validate check.
Thanks for reading my problem. Perhaps that can help anybody.

Backup validate :Error

Hi Expert,
while executing backup validate database archivelog all in one of the server i received this

What this means and is it any major concern?
Thanks
Shaan

this means you didn't have any archives and rman is unable to validate them.
RMAN does not actually produce backup sets, but rather reads the specified files in their entirety, to determine whether they can be backed up and are not corrupted.
