Tables with highest IO

Hello people,
Can you please provide a script that will display the tables with the highest physical read/write since a specific day.
(DBA_HIST_SEG_STAT, DBA_HIST_SYSSTAT ?)
Thank you in advance.

I have seen this table (v$segment_statistics), but my question is will this table give results based on historic data or based on live statistics?V$SEGMENT_STATISTICS is dynamic view, means it only holds the statistics from instance startup. If you wish to get the historic data, then AWR or Statspack. In this case yes, you can query DBA_HIST_SEG_STAT. The column of DBA_HIST_SEG_STAT will give you your answer something like this :
select PHYSICAL_READS_TOTAL,OBJ# from DBA_HIST_SEG_STAT order by 1;
I also need to have the tables ordered by reads - writes not for a specific table.So, order by value will not give you answer i.e. something like this ?
select object_name,owner,value
from V$SEGMENT_STATISTICS
order by value
where rownum<=10;
I think below link may also be of your interest :

Record with highest sy-tabix

Hi,
In an internal table I have 10 records for a field like
A
A
B
C
D
E
E
D
E
D
Is it possible to get the records D and E which has highest sy-index.
good solution will be rewarded.
Thanks and Regards,

just sort decending then fetch the first record then exit from loop.

Error while running spatial queries on a table with more than one geometry.

Hello,
I'm using GeoServer with Oracle Spatial database, and this is a second time I run into some problems because we use tables with more than one geometry.
When GeoServer renders objects with more than one geometry on the map, it creates a query where it asks for objects which one of the two geometries interacts with the query window. This type of query always fails with "End of TNS data channel" error.
We are running Oracle Standard 11.1.0.7.0.
Here is a small script to demonstrate the error. Could anyone confirm that they also have this type of error? Or suggest a fix?
What this script does:
1. Create table object1 with two geometry columns, geom1, geom2.
2. Create metadata (projected coordinate system).
3. Insert a row.
4. Create spacial indices on both columns.
5. Run a SDO_RELATE query on one column. Everything is fine.
6. Run a SDO_RELATE query on both columns. ERROR: "End of TNS data channel"
7. Clean.
CREATE TABLE object1

Thanks for help.

This error appears in GeoServer and SQLPLUS.
I have set up a completly new database installation to test this error and everything works fine. I tried it again on the previous database but I still get the same error. I also tried to restart the database, but with no luck, the error is still there. I geuss something is wrong with the database installation.
Anyone knows what could cause an error like this "End of TNS data channel"?

Error while importing a table with BLOB column

Also tell me "whether the BLOB is stored in different tablespace than the default tablespace of the user?"
Thanks in advance.

Hello,
U can either
1) create a tablespace with the same name in destination where you are trying to import.
2) get the ddl of the table, modify the tablespace name to reflect the existing tablespace name in destination and run the ddl in the destination database, and run your import command with option ignore=y--> which will ignore all the create errors.

Loop at table with unspecified type but with where-condition

Hi,
Doing a loop over an internal table with unspecified type and in addition using a condtion may be done as follows: Thereby the
condition would be "... WHERE parentid EQ i_nodeid" if the type of <it_htab> would be static. However dynamic specification of a component through bracketed character-type data objects is not possible.
FIELD-SYMBOLS: <it_htab> TYPE STANDARD TABLE,
                                <wa_htab> TYPE ANY,
                                <parentid> TYPE rsparent.
ASSIGN me->ref_htab->* TO <it_htab>.
LOOP AT <it_htab> ASSIGNING <wa_htab>.
    ASSIGN COMPONENT 'PARENTID' OF STRUCTURE <wa_htab> TO <parentid>.
    CHECK <parentid> EQ i_nodeid.
ENDLOOP.
Since you have to loop over the whole table and to check within the loop whether the condition is fullfilled, this is rather bad for performance.
Questions: Are there any tricks to do this better?
Best Regards and Thank you,
Ingo

only if you have the upcoming 7.0 EhP2 (Kernel 7.02 or 7.20) the following dynamic where works:
DATA cond_syntax TYPE string.
cond_syntax = `parentid = i_nodeid`.
LOOP AT <it_htab> ASSIGNING <wa_htab>
                       WHERE (cond_syntax).
in older releases you would have to use program generation to achieve a dynamic where... .

Load fact table with null dimension keys

Dear All,
We have OWB 10g R2 and ROLAP star schema. In our source system some rows don’t have all attributes populated with values (null value), and this empty attributes are dimension (business) keys in star schema. Is it possible to load fact table with such rows (some dimension keys are null) in the OWB mappings? We use cube operator in mappings.
Thanks And Regards
Miran

The dimension should have a row indicating UNKNOWN, this will have a business key outside of the normal range e.g. -999999.
In the mapping the missing business keys can then be NVL'd to -999999.

Can't update a sql-table with a space

Hello,
In a transaktion I'm getting some Values from a SAP-ERP System via JCO.
I update a sql-table with this values with a sql-query command.
But sometimes the values I get from SAP-ERP are empty (space) and I'm not able to update the sql-table because of a null-value exception. (The column doesn't allow null-values). It seems that MII thinks null and space are the same.
I tried to something like this when passing the value to the sql-query parameter but it didn't work:
stringif( Repeater_Result.Output{/item/SCHGT} == "X", "X", " ")
stringif( Repeater_Result.Output{/item/SCHGT} == "X", "X", " ")
this works but I don't want to have a "_"
stringif( Repeater_Result.Output{/item/SCHGT} == "X", "X", "_")
Any suggestions?
thank you.
Matthias

The problem is Oracle doesn't know the space function. But it knows a similar function: NVL --> replaces a null value with something else. So this statement works fine for me:
update marc set
LGort = '[Param.3]',
dispo = '[Param.4]',
schgt = NVL('[Param.5]', ' '),
dismm = '[Param.6]',
sobsl = NVL('[Param.7]',' '),
fevor = '[Param.8]'
where matnr = '[Param.1]' and werks = '[Param.2]'
If Param.5 or Param.7 is null Oracle replaces it with a space in every other case it is the parameter itself.
Christian, thank you for your hint with the space function. So I remembered the NVL-function.

Matthias

Hello Anybody, I have a question. Can any of you please suggest me how to make an xml file from the database table with all the rows? Note:- I am having the XSD Schema file and the resulted XML file should be in that XSD format only.

Hello Anybody, I have a question. Can any of you please suggest me how to make an xml file from the database table with all the records?
Note:- I am having the XSD Schema file and the resulted XML file should be in that XSD format only.

The Oracle documentation has a good overview of the options available
Generating XML Data from the Database
Without knowing your version, I just picked 11.2, so you made need to look for that chapter in the documentation for your version to find applicable information.
You can also find some information in XML DB FAQ

Creating table with null and not null values.

I have to create a table with 5 Null nd 5 Not Null fields.My questionis which fields are place first?Not or Not Null and why???

What you mean is: the person who asked you the question thought the order of columns was important, and wanted to see if you agreed. Or maybe they were just asking the question to see whether you thought it was important (as a test of your understanding of the database).
When I started out in Oracle I was told that it was good practice to have the mandatory columns first and then the optional columns. But if you do some research you find this: the impact of column ordering on space management is: empty nullable columns at the end of the table take up zero bytes whereas empty nullable columns at the middle of the table take up one byte each. I think if that saving really is important to you you need to spring for an additional hard drive.
Besides, even if you do organise your columns as you suggest, what happens when you add an eleventh NOT NULL column to your table? It gets tacked on to the end of your table. Your whole neat organisation is blown.
What does still matter is the positioning of large VARCHAR2 columns: they should be the last columns on your table in case they create chaining. Then any query that doesn't need the large columns can be satisfied without reading the chained block, something that can't be guaranteed if you've got columns after a VARCHAR2(4000) column. This doesn't apply to CLOBs, etc. which are stored separately anyway.

SRM MDM, Error, "Table with Code 'null' does not exist in repository"

Hi experts,
We has SRM MDM scenario, while doing OCI settings, we are able to connect with MDM repository but getting follwoing error message in portal, "java.lang.IllegalArgumentException: Table with Code 'null' does not exist in the repository 'Repository' or is one of the system table (e.g. Workflows) that is not exposed in repository schema"
Can You please suggest,
Thanks and Regards,
Munish

Hi everyone,
Sudhanshu and Anshuk:- Thanks for your response, let me try and explain the real scenario in details:-
We have deployed the SRM-MDM Catalog Search UI in Portal.
We tried accessing the http://<Portal Host>:<Portal Port>/SRM-MDM/SRM_MDM
Then we got a screen (Search UI App screen), where in we have provided the MDM Server name, then the MDM Server Password, then presses the Connect button, then below this, it displayed the Repository name created in the MDM. We have selected the Repository, then provided the Credentials of a User (Name: T_CORP) in MDM which has "Catalog Manager", and the "UI Configuration Manager" Roles. Please note that these Role names were created by us in MDM. Is it the right procedure or do we have any standard Roles delivered by SAP in MDM to map? If any standard Roles are available, where we need to check these.
Once the Credentials of MDM User is provided, and then selected the "Login" button.
Then we are getting the below error.
"java.lang.IllegalArgumentException: Table with Code 'null' does not exist in the repository 'Repository' or is one of the system table (e.g. Workflows) that is not exposed in repository schema"
Please clarify; we are not configuring any values in iViews. Where we need to do this, I mean name of the iView, and what values do we need provide generally? We are just running the Search UI App application; I don't think it is an iView, because the URL shows the Application name details, etc...
Please guide us, how to fix this Error.
Thanks and Regards,
Munish

Excel Table with Data Connection Manual Text Entry Misaligned After Refresh

Greetings!
I have an Excel 2010 workbook that includes a table linked to my SharePoint 2013 site by a data connection. The SharePoint list feeds the table standard information that's managed on the SharePoint site, but I need the user of the Excel workbook to be able
to enter text manually in the workbook to associate local information with the line-items coming from the SharePoint list. To do this, I've added extra columns to the end of the table.
The user can enter information in the appropriate cells in the "extra" columns at the end of the table, but when I refresh the data connection, the addition of a new list item on the SharePoint side results in the user's manually entered text getting
out of alignment with the row it's supposed to be associated with.
Example
Column 1(SP)
Column 2(Extra)
Row 1
Item 1
Row 2
Item 2
Text entered for Item 2
Row 3
Item 3
Then, if I add a new item to the list in SharePoint, for example, something that would appear between the original items 1 & 2, after refreshing the table, I get the following:
Column 1(SP)
Column 2(Extra)
Row 1
Item 1
Row 2
New Item 1.5
Text entered for Item 2
Row 3
Item 2
Row 4
Item 3
The table's data connection is set to insert rows for new items, and I could swear I had this working properly once upon a time...but I can't seem to make it work now.
Any thoughts on what would cause this?
Thanks in advance!

Yes, it is. I realized after posting the first time, that I'd assigned the question to the Visio forum. I wasn't sure how to reassign to the correct (Excel) forum, so I re-posted over there:

Issue in retrieving all the records from ADF Table with multiple row

Hi,
As per my requirement, I need to fill the table with multi selected LOV values and when user clicks on commit, I need to save them to database.
I am using ADF 11g, Multi select table. Using the below ADD method, I am able to add the records but if user clicks on cancel, I need to remove those from view and clear the table as well.
But the Issue I am facing is, in my cancel method, always I am getting half of the records. Lets assume table contains 100 records but in my cancel method, I am getting only 50 records.
Please let me know what is the issue in my source code.

Takes long time to drpo tables with large numbers of partitions

11.2.0.3
This is for a build. We are still in development. No risk of data loss. As part of the build, I drop the user,re-create it, re-create the objects. Allows us to test the build all the way through. Its our process.
This user has some tables with several 1000 partitions. I ran a 10046 trace and oracle is using pl/sql to do loops to do DML against the data dictionary. Anyway to speed this up? I am going to turn off the recyclebin during the build and turn it back on.
anything else I can do? Right now I just issue 'drop user cascade'. Part of is the weak hardware we have in the development/environment. Takes about 20 minutes just to run through this part of the script (the script has alot more pieces than this) and we do fairly frequent builds.
I can't change the build process. My only option is to try to make this run a little faster. I can't do anything about the hardware (lots of VMs crammed onto too few servers).
This is not a production issue. Its more of a hassle.

Support Note 798586.1 shows that DROP USER CASCADE was slower than dropping individual objects -- at least in 10.2 Not sure if it still the case in 11.2

It seems the query ask for database to using hashed table. would that be it will burden the database ? and impacted to others sap process ?
Please advise
Thank You and Best Regards

you can only argue coming from measurements and that is not the case.
Coming from the code, I see only that you do not understand it at all, so better leave it as it is. It is not a hash table, but a hash join on these table.
