Calculate checksum of data block manually?

I use bbed to check my database and find in the bad blocks, the computed checksum is different from the header value. Based on http://www.ixora.com.au/notes/cache_header.htm, the checksum is calculed with XOR algorithm. But when I calculate the data block checksum manually with XOR, the value does not match the computed value from bbed. What is the problem?

Things changed.
For which Oracle version did ixora run against?
Which is your Oracle version?
The supported way to find & report bad blocks is to invoke the dbv utility.

Satellite Pro U200 - Bad Checksum (ROM (Data Block) ) error

Hello when i start my Toahiba Satellite Pro U200
I have a Error
Bad Checksum (ROM (Data Block) )
PRESS ANY KEY TO CONINUE.
Pleas Help

The most common cause for "Bad Checksum" errors is the CMOS battery malfunction on the motherboard.
The battery could be empty or could simply be dead. But its really not easy to say whats wrong exactly!
Therefore I would recommend firstly to access the BIOS and to set it to default settings. Dont forget to save the changes.
Furthermore you should connect the AC adaptor and should let it connected for about 24hours to recharge the CMOS battery.
Maybe it helps to get rid of this error message.
If it doesnt help, then you should contact a notebook technician!

How to calculate the 'real data of arrival' in PO item

Hi,
Confirmation control keys with control type u201CDAu201D are MRP relevant
1.     = New field time of transportation in calendar days
2.     = Confirmation control type u201CABu201D (order confirmation)
3.     = Confirmation control type u201CLAu201D (shipping notification)
4.     = Confirmation control type u201CDAu201D (Date of arrival)
When data 1-3 has been changed = 4 will be calculated again.
Program requirements to calculate the u201Creal data of arrivalu201D:
1.     When 1 >0 days then create 4 directly after placement of 2 (2 can be placed manually or automatically)
2.     4 must be calculated: AB delivery date 2 + calendar date amount 1 = arrival date 4 (MRP gets a confirmed delivery      date by vendor plus transportation time)
3.     When changes in 1 then change 4 (add calendar days to arrival date DA)
4.      When changes in 2 then change 4 = u201Cnewu201D delivery date 2 plus calendar days 1 = new arrival date 4
5.     When 3 u201CLAu201D is entered (manually/automatically) then calculate: shipping date LA 3 plus calendar days 1 = new arrival date in 4
6.     When 1 has been changed then calculate 4 new (Check is 2 existing then use 2, check is 2 + 3 existing then use 3)
7.     When 2 or 3 has been changed quantity then also update quantity in 4
8.     When 2 has been canceled then cancel 4, too
9.     When 3 has an inbound delivery document no. in place then copy the same no. in the inbound delivery field 4 and in the new column in MRP (MD04, see MRP view below)
i have a lot of confuseging in this lines of code,even where u write i don't know in BADI . we are implement in BADI only.
if possiable give me code for this requriment. . this line of code in which method we write,please guide me.............

Manipulating data from a ref cursor in the data block of a form

I am using Oracle Forms 10g. I have a ref cursor which returns columns A, B, C, D, E where B, C, D, E are values. The "Query Data Source Name" attribute in the datablock contains "CCTR_Extract_pkg.cctr_refcur". The "Column Name" attribute of item A contains "A", item B contains "B", etc. All of these columns are displayed on the form and it all works perfectly.
I have a new request, the users would like a 6th column displayed - column F - where it equals D - B.
Is there any way of doing this in the form only or do I need to change the ref cursor to accomodate the new column and then the form?
If it can be achieved in the Form (only) - then how do I reference the 2 columns?
Thanks in anticipation
Michael

Is there any way of doing this in the form only or do I need to change the ref cursor to accomodate the new column and then the form? The REF_CURSOR is the data source of your block so you will have to modify the CCTR_Extract_pkg package and cctr_refcur REF_CURSOR.
If it can be achieved in the Form (only) - then how do I reference the 2 columns?After you have modified your database package, I recommend you run the Data Block Wizard on your block and let Forms detect the 2 new columns. You can do this manually, but it is safer to let Forms do it for you. If you want to do it manually, open the Query Data Source Columns property and add your new columns.
Hope this helps,

Inserting multiple records in a data block

Hi, how do i insert multiple rows from a record group into a data block. Thanks

You do it manually. Copy the values and move to the next record in the record group and in the block.
You might like the concept of basing a block on a stored procedure better. Check out the stored procedure based block sample that comes with the Oracle Forms demos.

Data block wizard breaks master-detail

I've encountered the following situation, and I'm wondering if it's a known bug or if I'm doing something wrong:
1. Open the data block wizard on an existing block that is the "detail" block of a master-detail relationship.
2. Add one new field to the block. No other changes are made.
3. When the form is recompiled and run, the master-detail relationship is broken. The detail block contains all the rows in the detail table. Clicking on the rows of the master block does not change the detail.
Adding a field to the block manually does not cause a problem. The relation is not impacted, and we see no property settings that are wrong. We tried downloading and installing all of the latest patches for forms 6i, and the problem occurs with that release as well. Any ideas?

I think you do something wrong because I add many fields many times and it works fine.
Thanks

Query Execution/Elapsed Time and Oracle Data Blocks

Hi,
I have created 3 tables with one column only. As an example Table 1 below:
SQL> create table T1 ( x char(2000));
So 3 tables are created in this way i.e. T1,T2 and T3.
T1 = in the default database tablespace of 8k (11g v11.1.0.6.0 - Production) (O.S=Windows).
T2 = I created in a Tablespace with Blocksize 16k.
T3 = I created in a Tablespace with Blocksize 4k. In the same Instance.
Each table has approx. 500 rows (So, table sizes are same in all the cases to test Query execution time ). As these 3 tables are created under different data block sizes so the ALLOCATED no. of data blocks are different in all cases.
T1 = 8k = 256 Blocks = 00:00:04.76 (query execution time/elapsed time)
T2 = 16k=121 Blocks = 00:00:04.64
T3 = 4k = 490 Blocks = 00:00:04.91
Table Access is FULL i.e. I have used select * from table_name; in all 3 cases. No Index nothing.
My Question is why query execution time is nearly the same in all 3 cases because Oracle has to read all the data blocks in each case to fetch the records and there is a much difference in the allocated no. of blocks ???
In 4k block size example, Oracle has to read just 121 blocks and it's taking nearly the same time as it's taking to read 490 blocks???
This is just 1 example of different data blocks. I have around 40 tables in each block size tablespace and the result are nearly the same. It's very strange for me because there is a much difference in the no. of allocated blocks but execution time is almost the same, only difference in milliseconds.
I'll highly appreciate the expert opinions.
Bundle of thanks in advance.
Best Regards,

Hi Chris,
No I'm not using separate databases, it's 8k database with non-standard blocksizes of 16k and 4k.
Actually I wanted to test the Elapsed time of these 3 tables, so for that I tried to create the same size
tables.
And how I equalize these is like I have created one column table with char(2000).
555 MB is the figure I wanted to use for these 3 tables ( no special figure, just to make it bigger than the
RAM used for my db at the db startup to be sure of not retrieving the records from cache).
so row size with overhead is 2006 * 290,000 rows = 581740000(bytes) / 1024 = 568105KB / 1024 = 555MB.
Through this math calculation I thought It will be the total table size. So I Created the same no. of rows in 3 blocksizes.
If it's wrong then what a mes because I was calculating tables sizes in the same way from the last few months.
Can you please explain a little how you found out the tables sizes in different block sizes.Though I understood how you
calculated size in MB from these 3 block sizes
T8K =97177 BLOCKS=759MB *( 97177*8 = 777416KB / 1024 = 759MB )*
T16K=41639 BLOCKS=650MB
BT4K=293656 BLOCKS=1147MB
For me it's new to calculate the size of a table. Can you please tell me then how many rows I can create in each of
these 3 tables to make them equal in MB to test for elapsed time.
Then I'll again run my test and put the results here. Because If I've wrongly calculated table sizes then there is no need to talk about elapsed time. First I must equalize the table sizes properly.
SQL> select sum(bytes)/1024/1024 "Size in MB" from dba_segments> 2 where segment_name = 'T16K';
Size in MB
655
Is above SQL is correct to calculate the size or is it the correct alternative way to your method of calculating the size??
I created the same table again with everything same and the result is :
SQL> select num_rows,blocks from user_tables where table_name = 'T16K';NUM_ROWS BLOCKS
290000 41703
64 more blocks are allocated this time so may be that's y it's showing total size of 655 instead of 650.
Thanks alot for your help.

Operate on a Tabular Data Block as a table?

hi
i was wondering if it is possible to query a tabular displayed data block like is done with tables. and do updates and inserts. so just to be clear, i dont want to query/insert/update the database table but the values in the form display items. i'm using oracle forms 9i
the main reason im asking this is because i want to use vaules in different records in the tabular displayed data block to make validations in the same data block... before the form is commited of course
thanks
venom_zx

You cannot query or manipulate blocks like table.
But you can manually navigate to each record in the block and validate before they are commited to the base table.

Relationship between a data block and latch

Hello Experts,
I have just read an article about indexes and full table scan by Richard Foote. http://richardfoote.wordpress.com/2009/04/16/indexes-on-small-tables-part-i-one-of-the-few/
I thought each block required only one latch for each operation. However, I don't undersand that why a single block required 2 latch? The qoute is the following,
Note that yes indeed, there were 4 consistent gets performed and that none of the consistent gets were the “cheaper” consistent gets examinations. Therefore, the 4 consistent gets used in performing the FTS of the one block table required 4 x 2 = 8 latches.
Can anyone explain the above quote please?
Thanks in advance.

Hello Sir,
I have just read Memory Architecture document, buffer states part, I know the meaning of dirty buffers. However, when we just SELECT any table, the corresponding data blocks that read into memory from disk, are they considered as clean buffers? Because as far as I understand from dirty buffers, these are modified buffers. And maybe the manual should have used "clean" instead of "free"?
The database uses a sophisticated algorithm to make buffer access efficient. Pointers to dirty and nondirty buffers exist on the same least recently used (LRU) list, which has a hot end and cold end. A coldbuffer is one that has not been recently used. A hot buffer is frequently accessed and has been recently used
Also the above statement is excerpt from Oracle Memory Architecture document, does the nondirty buffers refer to data blocks that move to the memory in SELECT query?
Thanks a lot for your remarkable thoughts.

Data block corrupted on standby database (logical corruption)

Hi all,
we are getting the below error on our DRSITE,it is MANUAL PHYSCIAL STANDBY DATABSE...
The following error has occurred:
ORA-01578: ORACLE data block corrupted (file # 3, block # 3236947)
ORA-01110: data file 3: '/bkp/oradata/orcl_raw_cadata01'
ORA-26040: Data block was loaded using the NOLOGGING option
I have checked in the Primary database, that there are some object which are not being logged into the redo logfiles.....

so the main problem is in the OM_EMPOYER tables if i would delete the indexes from that table recreate it again with the logging clause,and then apply the archvied logs to the DRSITE.WILL THE problem will resolve.
Pls suggest me...

Hi..
Firstly how did you confirm that it was that index only.Can you post the output of
SELECT tablespace_name, segment_type, owner, segment_name
FROM dba_extents WHERE file_id = 3 and 3236947 between block_id
AND block_id + blocks - 1;
This query can take time, if are sure that its the index don't fire this command .
Secondly, when you will drop and recreate the index, it will be logged into the redo logfile.This information will be be logged in to an the archivelog file as its the replica of the redo logfile. Then when you apply this archive log maually, it will drop that index and then recreate it using the same sql.

Data Block

Hi,As we all know data block is a combination of the sparse Dimension. IF i make a level 1 member of a sparse dimenison as a Dynamic Calc. Then i wanted to know how essbase will create a data block for that block. If if we perform calculation on it then will it work as usual as dynamic calc property results or will it be differ.

If a sparse member is dynamic - a block will not be created for it - even if you calculate that dimension.Regards,Jade-----------------------------Jade ColeSenior BI ConsultantClarity [email protected]

Single and Multiple Records On Same Data Block?

Hi all,
Im using forms 6i with db 9i.
Im having a nested table which contains a column of datatype TYPE(table of varchar2(100)).
Now i want to create a data block based on the nested table.
So, I want only one column should be multirecord in the block.
When i set the block level NO OF RECORDS PROPERTY to multiple, then all the items in the block getting changed as
multi records.
Is that possible to have multirecord for a particular field OR how to fix this issue?
Regards
Sankar MN
Edited by: SankarMCA on Oct 17, 2010 9:55 PM

Hi Baiq,
Thanks for your responses. I moved the multirecord item into a separate block(control block) and it worked.
But still im having a doubt regarding this.
How can we map a db column which has datatype of TYPE(Collection) to a particular item in forms?
Because when i try to create a new datablock based on that table im not able to move that collection column from
the available columns to database items in the datablock wizard. It seems like disabled and tree node structure and
im not able to select the same.
Next thing, Even though we assigned those column manually, How the commit_form save that multirecord column
with multiple values?
So kindly let me know how to solve this case if possible.

Upload data from microsoft access to oracle form(in data block)

Hi all,
Any one can help me, how we can upload data from access file to developer form(in data block).
as
we upload data from text file to developer form(in data block) using some packages.
Thank's in advance

Hi Zuhair,
If you give details of the problems you are still having then we should be able to get SQL*Developer to work.
However, if you don't want to use SQL*Developer then the following options are taken from note 393760.1 available in Metalink if you have access to that -
1. Use a gateway that supports the non-Oracle database or generic connectivity if a third party ODBC driver is available to do a -
'create Oracle_table as select from non_oracle_table@database_link'
for each table. You would then have to manually create all the other objects (views, indexes, stored procedurs etc) and permissions etc that existed in the non-Oracle database.
2. Use the SQL*Plus COPY command to copy data from the non-Oracle database to the
Oracle database using a gateway or generic connectivity. The syntax is as follows:
COPY FROM username/password@oracle_sid -
INSERT destination_oracle_table -
USING query;
The following example selects all rows from the EMP table in the non-Oracle database and
inserts them into the local Oracle EMP table:
COPY FROM SCOTT/TIGER@ora10 -
INSERT EMP -
USING SELECT * FROM SCOTT.EMP@gateway;
where "gateway" is the database link created for the gateway.
3. Load the non-Oracle data into flat files and use SQL*Loader to put the data into Oracle tables. Again manual
work is required for the other objects.
4. Contact the Oracle Product Technology Services (PTS) group for assistance. See the webpage -
http://www.oracle.com/technology/tech/migration//workbench/index_sqldev_omwb.html
5. Use a third party migration tool. See -
http://www.oracle.com/technology/tech/migration/isv/third_party.html
6. Use JDBC to connect to the non-Oracle database and Java in the Oracle database. This method will work but it is not suppported by the JDBC team.
=========
The amount of work involved will depend on the number and size of Access tables that you want to migrate.

Mike

Now, when I update a table field in the form and call the update stored procedure, this procedure takes the updated values in considerations, updates some more fields, and remove some records.
It is working as it should, except for two details :
1- I don't see the values updated by the procedure in the Form;
2- even though some records were removed from the table by the procedure, I still see all my records.
Is there a way to display the returned table?
And, is there any documentation about data block based on stored procedures, what are the required signatures and limitations of those stored procedures, what a lock procedure is supposed to do (mine does 'null;' ...), how to map a collection type defined in Oracle to a Form data block ? Any link will be appreciated, I have found half a dozen page vaguely detailing this on Google, but nothing that can compare to a usual Oracle manual. Maybe I have missed something.
Thank you for your help.

Yes, I was hoping to use these procedures to map the collection type returned to the database to the block data. I guess I was wrong. Except for the initial query and reading some other information from the database, I don't have to use these procedures as I do not write anything to it.
Thank you for your help, I will go on from there.
So, it means that I will have to iterate through my collection inside Forms and manipulate my data row by row. Or, is there a way to pass an Oracle collection type between the database and the Forms client and have it displayed without having to iterate through the rows and mapping each field?

Calculate checksum of data block manually?
