How Find space Used by Tables and Indexes

Dear All(s)
How i check space used (and number of rows) by each table and index in schema. ( can i check current space utilization and sysdate-date past in time)
How i can check used, and free space for each database and tablespace.
Thanks

You can always use the search feature

How to identify frequently accessed tables and indexes

Hi,
Could some one give me the exact queries to identify the frequently accessed Tabels and Indexes
Regards
Naveen

Hi,
depends from your definition of "frequently accessed" but i this you can use a query like this:
select owner,object_name, sum( value)
from V$SEGMENT_STATISTICS
where OBJECT_TYPE='TABLE'
and owner='NAVEEN_4_EX'
and STATISTIC_NAME in ('logical writes','logical reads')
group by owner,object_name

How to manage the space between a table and its title?

Have tables where titles are very close to the main text and need a couple of points to separate these elements. How to reshape this space?
1. Titles were separated by a return that is not visible... (any code is revealed by ID)
2. When a Return is inserted after the title, nothing happens aparently, but this return is now visible and could be used as a «paragraph space after» value:
3. A solution could be Grep to catch the end of paragraph assigned to titles to insert a return;
but Grep only catches the right border of the table (the yellow mark shows the big blinking cursor);
Grep cannot see the end of paragraph in the tables's title.
It another method?
Basically, how to modify the space between a table and ists title

I think you and Bob are not in synch here.
Bob suggested that you could use paragraph spacing, but for that to work you do need to use separate paragraphs for the title and table, which you don't seem to be doing. Using GREP to find the end of the paragraph only works if there IS and end to the paragraph. As far as I know there is now meta-character to use in Find/Change that would allow you to find a table and insert a paragraph break ahead of it, but I bet it could be scripted.
I'm not quite sure what you were trying to find in the GREP you posted. Did you actually have a paragraph return inserted already after the title? In that case you only need to redefine the style for that paragraph to add the space (or redefine the style for the paragraph that holds the table itself). You don't need the GREP. But the reason it does nothing is that you've found a location -- the end of the paragraph, but haven't found any actual text to modify. To do anything you would need to use something like .$
But back to NOT having a separate paragraph... If you put the cursor in any table cell and go to Table Options > Table Setup tab you'll see fields to set space before and after the table that should do what you want. That was the second part of what he posted.

How can I use Hash Table when processing the data from cdpos and cdhdr

Hello Guru,
I've a question,
I need to reduce the access time to both cdhdr and cdpos.
Because may be I'll get a huge number of entries.
It looks like that by processing cdhdr and cdpos data will take many secondes,
it depends on how many data you need to find.
Hints : Putting instructions inside a form will slow down the program?
Also, I just want use Hash table and I need to put a loop-instruction going on the hash-table in form.
I know that it's no possible but I can declare an index inside my customized hash table.
For example :
DO
READ TABLE FOR specific_hash_table WITH KEY TABLE oindex = d_oindex.
Process data
d_oindex += 1.
UNTIL d_oindex = c_max_lines + 1.
Doing this would actually not necessary improve the performance.
Because It looks like I'm having a standard table, may be there's a hash function, but it could be a bad function.
Also I need to use for example COUNT (*) to know how many lines I get with the select.

How to find schema of a table and a view

Hi,
I have an old form which uses one table and one view. I know its database. Now I'm making another form in some other database and want to use the old form but for that I need to know the schema of that table and the view so that I can give the schema name and db link to connect (meaning schema.table_name@dbname). How do I find out the schema for that table and view.
I did a search by using "select owner from all_objects where object_name = tablen" and it says PUBLIC. There's no schema called Public. I can see Public Synonyms but cannot find that table and view in it. So please help. I'm trying since long to find its schema.
Thanks.

Hi ,
Isn't it peculiar that i have declared a public synonym on table BIOGR as user523269 does.... and the sql statement:
select owner from all_objects where object_name='BIOGR' works.... whereas of user523269 does not...?????
SQL> select * from dba_synonyms where table_name='BIOGR';
OWNER SYNONYM_NAME TABLE_OWNER TABLE_NAME DB_LINK
PUBLIC BIOGR HIS BIOGR Regards,
Simon

Space Allocated and Space used for Table.

Hi,
Is there any way, we can find Space Allocated and Space used for Table wise.
I know USER_TABLESPACES help use to find table space wise. But I would like to know, the space utilized by each table in the specific table space.

Check this link from Tom Kyte about it.

How to partition tables and indexes in this scenario?

So our situation is pretty simple. We have 3 tables.
A, B and C
the model is A->>B->>C
Currently A, B and C are range partitioned on a key created_date however it's typical that only C is every qualfied with created date. There is a foreign key from B -> A and C -> B
we have many queries where the data is identified by state that is indexed currently non partitioned on columns in A ... there are also indexes on the foreign keys that get from C -> B -> A. Again these are non partitioned indexes at this time.
It is typical that we qualify A on either account or user or both. There are indexes (non partitioned) on these
We have a problem now because many of the queries use leading wildcards ie. account like '%ACCOUNT' etc. This often results in large full table scans. Our solution has been to remove the leading wildcard but this isn't always possible.
We are wondering how we can benefit from partitioning and or sub partitioning table A. since it's partitioned on created_date but rarely qualify by that.
We are also wondering where and how we can benefit from either global partitioned index or local partitioned indexes on tables A. We suspect that the index on the foreign key from C to B could be a local partitioned index.
I am also wondering what impact pushing the state from A that's used to qualify A down to C would have any advantage.
C is the table that currently we qualify with the partition key so I figure if you also pushed down the state from A that's used to qualify the set of C's we want based on the set of B's we want based on the set of A thru qualfying on columns within A.
If we push down some of those values to C and simply use C when filtering I'm wondering what the plans will look like compared to having to work all the way up from the bottom to the top before it begins qualifying A.

We are wondering how we can benefit from partitioning and or sub partitioning table A. since it's partitioned on >created_date but rarely qualify by that. Very good question. Why did you partition on it? You will never have INSERTS on these partitions, but maybe deletes and updates? The only advantage (I can think of) would be to set these partitions in a read only tablespace to ease backup... but that's a weired reason.
we have many queries where the data is identified by state that is indexed currently non partitioned on columns in >A ... there are also indexes on the foreign keys that get from C -> B -> A. Again these are non partitioned indexes at >this time.Of course. Why should they be partitioned by Create_date?

We have a problem now because many of the queries use leading wildcards ie. account like '%ACCOUNT' etc. This >often results in large full table scans. Our solution has been to remove the leading wildcard but this isn't always possible.I would suspect full index scan. Isn't it?
We are also wondering where and how we can benefit from either global partitioned index or local partitioned >indexes on tables A. We suspect that the index on the foreign key from C to B could be a local partitioned index.As A is not accessed by any partition, why should C and B profit? You should look to partition by the key you are using to access. But, you are looking to tune your SQLs where the access is like '%ACCOUNT' on A. Then when there is a match. ORACLE joins via your index and nested loop (right?) to B and C.
I am also wondering what impact pushing the state from A that's used to qualify A down to C would have any >advantage.Why should it. It just makes the table and indexes larger => more IO.
C is the table that currently we qualify with the partition key so I figure if you also pushed down the state from A >that's used to qualify the set of C's we want based on the set of B's we want based on the set of A thru qualfying >on columns within A.If the access from A to C would be .. AND A.CREATE_DATE =C.CREATE_DATE and c.key like '%what I want%' which does not qualifify for a FK ;-) then, as that could be resulting in a partition scan, you could "profit". But, I'm sure that's not your model.
If we push down some of those values to C and simply use C when filtering I'm wondering what the plans will look >like compared to having to work all the way up from the bottom to the top before it begins qualifying A.So you want to denormalize A,B,C and into one table? With the same access is like '%ACCOUNT' you would get a full scan on an index as before, just the objects would be larger due to redundance and harder to maintain. In the end you would have a bad and slower design.
Maybe you explain what the problem is.
Full index scan can not be avoided, but that can be made faster by e.g. parallel query, and then the join to B and C should be a "snip" if you just identify a small subset of rows in these tables.

How to find last accessed/updated tables and the query text?

I am using :
Oracle8i Enterprise Edition Release 8.1.7.4.0 - Production

JServer Release 8.1.7.4.0 - Production
How to find last accessed/updated tables and the query text?
Regards
LEE1212

Check DBA_TBALES view there you find one date column that indicate last update
One option is as follows:
(1) Turn the auditing on: AUDIT_TRAIL = true in init.ora
(2) Restart the instance if its running.
(3) Audit the table:
     AUDIT INSERT,SELECT,DELETE,UPDATE on TableName
     by ACCESS WHENEVER SUCCESSFUL
(4) Get the desired information using :
     SELECT OBJ_NAME,ACTION_NAME ,to_char(timestamp,'dd/mm/yyyy , HH:MM:SS')
     from sys.dba_audit_object.

Script to find out table and index candidates to keep in the buffer pool

I am looking for a script to find out tables and indexes to keep in the buffer pool.
Could you help me on this ?
thanks...
Markus

this is more of a open question. As you know ur data well. We do not know whats ur data. cachin tables in buffer pool is okay, but it might age out after not being used...instead you can use the KEEP POOL...to cache small tables/popular tables into the keep pool...as keep pool guarantees full caching .....
here are some links on keep pool cacheing

Hi All,
For several transactions we have caprtured all the filed names along with the technical names.
Ex : in VA03 - in the initial screen ,postal code field is there.When i see F1 help for that field i could see POST_CODE2 as its technical name.
But i want to see the actuall DDIC table field which corresponds to this field that is LFA1-PSTLZ.
Like wise there are so many T-codes for which i need do the same thing.But for some transactions i am unable to find out the database tables and the corresponding fields.Please suggest any other easier way to do this.
Is there any way to find out all the DDIC tables and fields that gets updated for a Tcode?
Please help me out in this.

DB02 = Missing Tables and Indexes = Unknown objects in ABAP Dictionary = DB views

Hi SAP Gurus,
on our SAP NetWeaver 7.x BW (based on AIX/Oracle) I find via transaction DB02 (path = Diagnostics => Missing Tables and Indexes) under "Unknown objects in ABAP Dictionary" under DB views a BW object /BI0/.....
When I make a double click on the object, I am getting the popup window "Display not possible for this object":
How can I identify the object and clarify with the BW application expert, if needed, how to resolve this object?
I searched already via RSA1 for the object, but I wasn't able to find anything so far ...
Thanks for your help and ideas.
Best regards
Carlos

Hello Carlos
The database view in question is a temporary database object created during a query execution.
Please read this SAP note 449891 - Temporary database objects in BW 3.x to understand what that view is all about and impact if those views are removed.
The SAP notes 449891 and 1139396 suggests to run the report SAP_DROP_TMPTABLES to drop these temporary objects. Whether the objects are still required or not is a question to be put across to the BW team. If the temporary objects are removed when they are used by a query, then the query will fail.
Have a nice day

Generate the tablespace clause for tables and indexes

How can I make Designer generate the tablespace clause for the create table and create index statements?
I assigned tables and indexes to Tablespaces objects in designer but they don't seem to have any effect on the generator.
I am using the latest version of Oracle Designer.
Thanks

Guess I am not real clear what you want.
In the DB admin tab you will need to create the tablespace with the data file.
Then you need to assign the table space to the table.
You will need to generate from the DB Admin tab.
Hope this helps.
