Import parametes and insert into database table suggestions

experts need suggestions
created a table with 3 fields.
zstable.
field dataelement type length
kunnr kunnr      char 10       key field
name   dname      char   30      key field
aedat aedat        dats 8
aenam aenam       char 12
now i am creating a function modlue with two input parameters
1)kunnr
2)name
i want to update this two fields into table zstable.
1. so suggest me the best way to do this.
Delcarations in import options which one of the below is best and why?
name type char30
kunnr type kunnr
or
name like zstable-name
kunnr like zstable-kunnr
or
kunnr type zstable-kunnr
name type zstable-name.
2. inserting into table
the data that we recieve from the import parameters need to be inserted into the zstable.
please suggest me the appropriate statement waht i need to code for this.
insert kunnr name into zstable.
can i ignore the third field as it is not the key field?
3. before inserting do i need to check whether kunnr and uname is initial ie import parametrs?
4. suppose if i delcared two input parameters in function module zfuntion say vbeln and posnr.
and source code
insert vbeln and posnr into zstable.
now i am calling from the program
zreport.
call function 'ZFUNCTION'.
EXPORT
NAME =
KUNNR =
Will the above statement updates the blank records into the table zstable?.

Hi,
1) I think the best is either refer directly to data element or to table field. This is beacuse once any change is made to this data element it will automatically reflect in your parameters. For table fields it is a bit less safier but still correct. Golden rule - always try to refer to DDIC components like data elements.
name type dname
kunnr type kunnr
2) You need to provide all key fields. I recommend to use MODIFY as it would hanlde both INSERT (if yet no such record exists ) and UPDATE (if already exists).
data: wa_zstable type zstable. "declare work area
wa_zstable-kunnr = kunnr. "pass parameters here
wa_zstable-name = name.
modify zstable from wa_zstable.
3) good practise, for this use
if kunnr is initial and
   name is initial.
"modify ...
endif.
"or if parameters are set as OPTIONAL, then use
if kunnr is supplied and
   name is supplied.
endif.
4) No, the statment you want to use
insert vbeln and posnr into zstable.
is only used for FIELD GROUPS, not DB table. Please refer [INSERT|http://help.sap.com/abapdocu/en/ABAPINSERT_DBTAB_SHORTREF.htm] for correct syntax.
You can alternatively use somthing like
UPDATE zstable SET vbeln = ...
                                        posnr = ...
                                 WHERE ...
This will update fields VBELN and PONR for all records fullfilling WHERE condition. These however musn't be key fields, only non-key fields can be udpated.

Its very urgent:how to insert data into database tables

Hi All,
I am very new to oaf.
I have one requirement data insert into database tables.
here createPG having data that data insert into one custom table.
but i dont know how to insert data into database tables.
i wrote the code in am,co as follows.
in am i wrote the code:
public void NewoperationManagerLogic()
ManagerCustomTableVOImpl vo1=getManagerCustomTableVO1();
OADBTransaction oadbt=getOADBTransaction();
if(!vo1.isPreparedForExecution())
vo1.executeQuery();
Row row=vo1.createRow();
vo1.insertRow(row);
in createPG processrequest co:
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
super.processRequest(pageContext, webBean);
ManagerInformationAMImpl am=(ManagerInformationAMImpl)pageContext.getApplicationModule(webBean);
am.NewoperationManagerLogic();
process form request:
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
super.processFormRequest(pageContext, webBean);
if(pageContext.getParameter("Submit")!=null)
ManagerInformationAMImpl am=(ManagerInformationAMImpl)pageContext.getApplicationModule(webBean);
am.getOADBTransaction().commit();
please help with an example(sample code).
its very urgent.
thanks in advance

Hi ,
1.)You must have to create a EO based on custom table and then VO based on this EO eventually to save the values in DB
2.) the row.setNewRowState(Row.STATUS_INITIALIZED); is used to set the the status of row as inialized ,this is must required.
3.) When u will create the VO based on EO the viewattributes will be created in VO which will be assigned to the fields to take care the db handling .
You must go thtough the lab excercise shipped with you Jdeveloper ,there is a example of Create Employee page ,that will solve your number of doubts.

Inserting Multiple Rows into Database Table using JDBC Adapter - Efficiency

I need to insert multiple rows into a database table using the JDBC adapter (receiver).
I understand the traditional way of repeating the statement multiple times, each having its <access> element. However, I am just wondering whether this might be performance-inefficient, as it might insert records one by one.
Is there a way to ensure that the records are inserted into the table as a block, rather than record-by-record?

Hi Bhavesh/Kanwaljit,
If we have multiple ACCESS tags then what happens is that the connection to the database is made only once. But the data is inserted row by row.
Why i am saying this?
If we add the following in JDBC Adapter..logSQLStatement = true. Then incase of multiple inserts we can see that there are multiple
<i>Insert into tablename(EMP_NAME,EMP_ID) VALUES('J','1000')
Insert into tablename(EMP_NAME,EMP_ID) VALUES('J','2000')</i>
Doesnt this mean that rows are inserted one by one?
Correct me if i am wrong.
This does not mean that the transaction is not guaranted. Either all the rows will be inserted or rolled back.

Sumit

Inserting new records into database table at runtime

Hi all ,
How to insert new records into database table at runtime on click update?
Thanks.

Hi Sasikala,
Just for your understanding am giving a sample code snippet which you can use to read the contents of your Table UI element & save the data on to your database. Suppose you have a button up on pressing which you want to read the data from your screens table & save on to the database then you can proceed as shown below:
1) Obtain the reference of your context node.
2) Fetch all the data present in your table into an internal table using methods of if_wd_context_node
3) Use your normal ABAP logic to update the database table with the data from your internal table
In my example I have a node by name SFLIGHT_NODE and under this I have the desired attributes from SFLIGHT. Am displaying these in an editable table & the user would press up on a push button after making the necessary changes to the tables data. I would then need to obtain the tables information & save on to the database.
data: node_sflight           type ref to if_wd_context_node,
        elem_sflight           type ref to if_wd_context_element,
        lt_elements            type WDR_CONTEXT_ELEMENT_SET,
       stru_sflight           type if_main=>element_sflight_node,
       it_flights             type if_main=>elements_sflight_node.
"   navigate from <CONTEXT> to <SFLIGHT_NODE> via lead selection
    node_sflight_node = wd_context->get_child_node( name = 'SFLIGHT_NODE' ).
   lt_elements = node_sflight->get_elements( ).
"   Get all the rows from the table for saving on to the database
    loop at lt_elements into elem_sflight.
      elem_sflight->get_static_attributes( importing static_attributes = stru_sflight ).
      append stru_sflight to it_flights.
    endloop.
" Finally save the entries on to the database
    modify ZSFLIGHT99 from table it_flights.
    if sy-subrc eq 0.
endif.
However a word of caution here.... SAP doesn't ever recommend directly modifying the database through an SQL query. You would preferably make use of a BAPI for the same. Try go through Thomas Jung's comments in [here|modify the data base table which is comming dynamiclly;.

How can I insert into a table other than the default table in a form

Hi,
I want to insert into a table with some fields value of a form of another table. I have written insert code On successful submission of that form, but after submit it gives the following error
An unexpected error occurred: ORA-06502: PL/SQL: numeric or value error (WWV-16016)
My code is like this
declare
l_trn_id number;
l_provider_role varchar2(3);
l_provider_id varchar2(10);
begin
l_trn_id := p_session.get_value_as_number(p_block_name=>'DEFAULT',p_attribute_name=>'A_TRANSACTION_ID');
l_provider_id := p_session.get_value_as_varchar2(p_block_name=>'DEFAULT',p_attribute_name=>'A_PROVIDER1');
l_PROVIDER_ROLE := p_session.get_value_as_varchar2(p_block_name=>'DEFAULT',p_attribute_name=>'A_PROVIDER_ROLE1');
if (l_provider_role is not null) and (l_provider_id is not null) then
insert into service_provider_trans_records(service_provider_id,transaction_id,role_type_id)
values(l_provider_id, l_trn_id, l_provider_role);
commit;
end if;
end;
Where 'PROVIDER1' and 'PROVIDER_ROLE1' are not table fields.
How can do that or why this error comes ? Any idea?
Thanks
Sumita

Hi,
When do you get this error? Is it while running or while creating the form.
Here is a sample code which inserts a non-database column dummy into a table called dummy. This is done in successful procedure.
declare
l_dummy varchar2(1000);
begin
l_dummy := p_session.get_value_as_varchar2(p_block_name=>'DEFAULT',
p_attribute_name=>'A_DUMMY');
insert into sjayaram903_1g.dummy values(l_dummy);commit;
end;
Please check in your case if the size of the local variable is enough to hold the values being returned.
Thanks,
Sharmila

Inserting into a table which is created "on the fly" from a trigger

Hello all,
I am trying to insert into a table from a trigger in Oracle form. The table name however, is inputted by the user in am item form.
here is what the insert looks like:
insert into :table_name
values (:value1, :value2);
the problem is that forms does not recognize ::table_name. If I replace :table_name with an actual database table, it works fine. However, I need to insert to a table_name based from oracle form item.
By the way, the table|_name is built on the fly using a procedure before I try to insert into it.
Any suggestion on how can I do that? My code in the trigger is:
declare
dm_drop_tbl(:table_name,'table) // a call to an external procedure to drop the table
dm_create_tbl(:table_name,'att1','att2');
insert into :table_name
values (:value1, :value2);
this give me an error:
encounter "" when the symbol expecting one.....

Hi ,
You should use the FORMS_DDL built_in procedure. Read the on-line documentation of forms ...

Problem while inserting into a table which has ManyToOne relation

Problem while inserting into a table *(Files)* which has ManyToOne relation with another table *(Folder)* involving a attribute both in primary key as well as in foreign key in JPA 1.0.
Relevent Code
Entities:
public class Files implements Serializable {
@EmbeddedId
protected FilesPK filesPK;
private String filename;
@JoinColumns({
@JoinColumn(name = "folder_id", referencedColumnName = "folder_id"),
@JoinColumn(name = "uid", referencedColumnName = "uid", insertable = false, updatable = false)})
@ManyToOne(optional = false)
private Folders folders;
public class FilesPK implements Serializable {
private int fileId;
private int uid;
public class Folders implements Serializable {
@EmbeddedId
protected FoldersPK foldersPK;
private String folderName;
@OneToMany(cascade = CascadeType.ALL, mappedBy = "folders")
private Collection<Files> filesCollection;
@JoinColumn(name = "uid", referencedColumnName = "uid", insertable = false, updatable = false)
@ManyToOne(optional = false)
private Users users;
public class FoldersPK implements Serializable {
private int folderId;
private int uid;
public class Users implements Serializable {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Integer uid;
private String username;
@OneToMany(cascade = CascadeType.ALL, mappedBy = "users")
private Collection<Folders> foldersCollection;
I left out @Basic & @Column annotations for sake of less code.
EJB method
public void insertFile(String fileName, int folderID, int uid){
FilesPK pk = new FilesPK();
pk.setUid(uid);
Files file = new Files();
file.setFilename(fileName);
file.setFilesPK(pk);
FoldersPK folderPk = new FoldersPK(folderID, uid);
// My understanding that it should automatically handle folderId in files table,
// but it is not…
file.setFolders(em.find(Folders.class, folderPk));
em.persist(file);
It is giving error:
Internal Exception: java.sql.SQLException: Field 'folderid' doesn't have a default value_
Error Code: 1364
Call: INSERT INTO files (filename, uid, fileid) VALUES (?, ?, ?)_
_ bind => [hello.txt, 1, 0]_
It is not even considering folderId while inserting into db.
However it works fine when I add folderId variable in Files entity and changed insertFile like this:
public void insertFile(String fileName, int folderID, int uid){
FilesPK pk = new FilesPK();
pk.setUid(uid);
Files file = new Files();
file.setFilename(fileName);
file.setFilesPK(pk);
file.setFolderId(folderId) // added line
FoldersPK folderPk = new FoldersPK(folderID, uid);
file.setFolders(em.find(Folders.class, folderPk));
em.persist(file);
My question is that is this behavior expected or it is a bug.
Is it required to add "column_name" variable separately even when an entity has reference to ManyToOne mapping foreign Entity ?
I used Mysql 5.1 for database, then generate entities using toplink, JPA 1.0, glassfish v2.1.
I've also tested this using eclipselink and got same error.
Please provide some pointers.
Thanks

Hello,
What version of EclipseLink did you try? This looks like bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=280436 that was fixed in EclipseLink 2.0, so please try a later version.
You can also try working around the problem by making both fields writable through the reference mapping.

Chris

Record not inserting into the table through Forms 10g

Hi all,
I have created a form in 10g(10.1.2.0.2) based on just one table that has 4 columns(col1, col2, col3, col4).
Here col1, col2 and col3 are VARCHAR2 and col4 is date and all the columns are not null columns(There are no primary and foriegn key constrains, which means duplicates are allowed).
My form contains 2 blocks where block 1 has one text item (col1) and 3 buttons (Delete, Save, Exit).
And block2 is a database block and has col2,col3,col4 which are in tabluar layout frame displaying 10 records.
When the form is opened the cursor has to be in block1.col1 for querrying. Here i enter a value in col1, and then when I click on col2 in the block2, then I put execute_query in new_block_instance of block2, which displays the records.
The block2 properties are not updatable, insertable and query is allowed.
Everything is working good until here. But here in the block2 when I want to insert another record into the table, by navigating all the way down to the last empty record and entering the new values for col2, col3 and col4 And then Ctrl+S will display the message "*FRM-40400: Transaction complete: 1 record applied and saved.*" But actually the record is not inserted into the table.
I also disabled the col4 by setting the Enabled property to No, since while inserting new record the date have to be populated into it and it shouldnt be changed by the user. And im populating the sysdate into the new record by setting Intial Value property to *$$DATE$$*.
And another requirement which I could not work arround here is that, the col3 also should be populated with the username of the user while inserting.
please help me...

Hi Sarah,
I do not want to update the existing record. So I kept Udate Allowed to No in property palette for the items in block2.
Do I have to do this property at block level also?
I'm inserting a new record here.

Fetch data from one table and insert into two tables in desired format

I have similar to the following data in a table and it is not normalized. The groupID is being used to group two records of similar nature.
DECLARE @OldDoc TABLE (oldDocID INT, groupID INT, deptID INT)
INSERT INTO @OldDoc (oldDocID, groupID) VALUES (1, NULL, 111),(2,NULL,111),(3,1,111),(4,NULL,333),(5,1,222),(6,NULL,333),(7,2,222),(8,2,333),(9,NULL,111),(10,3,222),(11,NULL,333),(12,3,444)
I need to process the data from the above table (@OldDoc) and write into two new tables (@NewDoc and @NewDocGroup) as follows.
oldDocID should be stored as newDocID when inserting to @NewDoc table. Only records with groupID NULL and one record (first one) per group should be considered (For example, oldDocID 5 is not considered as 3 and 5 belong to the same groupID 1) for insertion.
DECLARE @NewDoc TABLE (newDocID INT)
INSERT INTO @NewDoc (newDocID) VALUES (1),(2),(3),(4),(6),(7),(9),(10),(11)
All records from @OldDoc should be considered for insertion into @NewDocGroup table. OldDocID is inserted as NewDocID and deptID is as-is. Instead of groupID, the ID of the first record in the
group should be considered as parentNewDocID (For example, 3 is considered as parentNewDocID for newDocID 5 as 3 and 5 belong to the same groupID in @OldDoc table) for the newDocID.
DECLARE @NewDocGroup (newDocID INT, parentNewDocID INT, deptID INT)
INSERT INTO @NewDocGroup (newDocID, parentNewDocID, deptID) VALUES (1,1,111),(2,2,111),(3,3,111),(4,4,333),(5,3,222),(6,6,333),(7,7,222),(8,7,333),(9,9,111),(10,10,222),(11,11,333),(12,10,444)
How do I accomplish the above using SQL ? Thanks for the help.

>> I have similar to the following data in a table and it is not normalized. The group_id is being used to group two records [sic] of similar nature. <<
Rows are not records. Tables have to have a key by definition. You do not do math with identifiers, so they should not be numeric. Let's ignore that error for now. In short, you are posting garbage. If you had followed Forum Netiquette, would you have posted
this?
CREATE TABLE Old_Documents
(old_doc_id INTEGER NOT NULL PRIMARY KEY,
group_id INTEGER,
dept_nbr INTEGER NOT NULL
REFERENCES Departments (dept_nbr));
INSERT INTO Old_Documents(old_doc_id, group_id, dept_nbr)
VALUES (1, NULL, 111),
(2, NULL, 111),
(3, 1, 111),
(4, NULL, 333),
(5, 1, 222),
(6, NULL, 333),
(7, 2, 222),
(8, 2, 333),

(12, 3, 444);
>> I need to process the data from the above table (Old_Documents) and write into two new tables (New_Documents and New_Documents_Groups) as follows. <<
Just like punch cards and mag tape data processing! Being old and being new are a status, not another kind of entity. But that is how mag tapes work. And you even use the verb "fetch" from tape files. This design flaw is called attribute splitting.
Do you have a Male_Personnel and Female_Personnel table? NO! It is just Personnel!
>> old_doc_id should be stored as new_doc_id when inserting to New_Documents table. Only records [sic] with group_id NULL and one record [sic] (first [sic; no ordering in a table] one) per group should be considered (For example, old_doc_id 5 is not considered
as 3 and 5 belong to the same group_id =1) for insertion. <<
Think about your punch card mindset. Why did you physically materialize that redundant New_Documents table? Let me answer that: this is how you work with punch cards! In SQL we use a VIEW:
CREATE VIEW New_Documents (new_doc_id)
AS
SELECT old_doc_id
FROM Old_Documents;
>> All records [sic] from Old_Documents should be considered for insertion into New_Documents_Groups table. The old_doc_id is inserted as new_doc_id and dept_nbr is as-is. Instead of group_id, the ID [sic: which identifier??] of the first [sic: tables
have no ordering like a deck of punch cards] record [sic] in the group should be considered as parent_new_doc_id (For example, 3 is considered as parent_new_doc_id for new_doc_id 5 as 3 and 5 belong to the same group_id in Old_Documents table) for the new_doc_id.
<<
Why not use 5 as the parent? My guess is that you are trying to form equivalence classes. See:

Trigger a process when a record is inserted into database

Hi, could someone tell me how to do the following (if it's possible):
when a record is inserted into a table in a database,
I want it to somehow trigger an action which will put an item into user's To-Do inBox of the WorkSpace,
the user can then open the form in the To-Do and use it to view the data in the newly inserted record.
this "user"'s login ID is part of the inserted record.
thanks

Mmm, trigger? I don't know of a way.
But I supposed you could have a process that has a timer that peroidically queries the database for changes and then do the same thing.
You could also perhaps write a Service and then use the Java API to start a process?
Maybe take a look here

Insert into two tables, how to insert multiple slave records

Hi, I have a problem with insert into two tables wizard.
The wizard works fine and I can add my records, but I need to enter multiple slave table records.
My database:
table: paper
`id_paper` INTEGER(11) NOT NULL AUTO_INCREMENT,
`make` VARCHAR(20) COLLATE utf8_general_ci NOT NULL DEFAULT '',
`model` VARCHAR(20) COLLATE utf8_general_ci NOT NULL DEFAULT '',
`gsm` INTEGER(11) NOT NULL,
PRIMARY KEY (`id_paper`)
table: paper_data
`id_paper_data` INTEGER(11) NOT NULL AUTO_INCREMENT,
`id_paper` INTEGER(11) NOT NULL,
`value` DOUBLE(15,3) NOT NULL,
`nanometer` INTEGER(11) NOT NULL,
PRIMARY KEY (`id_paper_data`)
I need to add multiple fields "value" and "nanometer"
Current form looks like this:
Make:
Model:
Gsm:
Value:
nanometer:
I need it to look like this:
Make:
Model:
Gsm:
Value:
nanometer:
Value:
nanometer:
Value:
nanometer:
Value:
nanometer:
and so on.
The field "id_paper" in table paper_data needs to get same id for entire transaction. Also how do I set default values for each field "nanometer" on my form the must be different (370,380,390 etc)?
Thanks.

Hi experts,
Im using ADDT to design a page that needs to insert one record into a master ALBUMS table, along with three records into a GENRES table, all linked by the primary, auto-incremented ALBUMS. ALBUM_ID.
Ive tried many different ways of combining the Insert into Multiple Tables wizard and the insert record wizard with Link Transactions, all with no luck. Either only the album info gets inserted, or a ALBUM_ID cannot be null error from MySQL. Here is the structure of the tables
ALBUMS
ALBUM_ID, INT(11), Primary, Auto_Increment
alb_name, varchar
alb_release, YEAR
USER_ID, int
alb_image, varchar
GENRES
ALBUM_ID, int, NOT NULL
GENRE_ID, int, NOT NULL
ID, int, primary, auto-increment

Constantly inserting into large table with unique index... Guidance?

Hello all;
So here is my world. We have central to our data monitoring system an oracle database running Oracle Standard One (please don't laugh... I understand it is comical) licensing.
This DB is about 1.7 TB of small record data.
One table in particular (the raw incoming data, 350gb, 8 billion rows, just in the table) is fed millions of rows each day in real time by two to three main "data collectors" or what have you. Data must be available in this table "as fast as possible" once it is received.
This table has 6 columns (one varchar usually empty, a few numerics including a source id, a timestamp and a create time).
The data is collect in chronological order (increasing timestamp) 90% of the time (though sometimes the timestamp may be very old and catch up to current). The other 10% of the time the data can be out of order according to the timestamp.
This table has two indexes, unique (sourceid, timestamp), and a non unique (create time). (FYI, this used to be an IOT until we had to add the second index on create time, at which point a secondary index on create time slowed the IOT to a crawl)
About 80% of this data is removed after it ages beyond 3 months; 20% is retained as "special" long term data (customer pays for longer raw source retention). The data is removed using delete statements. This table is never (99.99% of the time) updated. The indexes are not rebuilt... ever... as a rebuild is about a 20+ hour process, and without online rebuilds since we are standard one, this is just not possible.
Now what we are observing is that the inserts into this table
- Inserts are much slower based on a "wider" cardinality of the "sourceid" of the data being inserted. What I mean is that 10,000 inserts for 10,000 sourceid (regardless of timestamp) is MUCH, MUCH slower than 10,000 inserts for a single sourceid. This makes sense to me, as I understand it that oracle must inspect more branches of the index for uniqueness, and more different physical blocks will be used to store the new index data. There are about 2 million unique sourceId across our system.
- Over time, oracle is requesting more and more ram to satisfy these inserts in a timely matter. My understanding here is that oracle is attempting to hold the leafs of these indexes perpetually buffers. Our system does have a 99% cache hit rate. However, we are seeing oracle requiring roughly 10GB extra ram per quarter to 6 months; we're at about 50gb of ram just for oracle already.
- If I emulate our production load on a brand new, empty table / indexes, performance is easily 10x to 20x faster than what I see when I do the same tests with the large production copies of data.
We have the following assumption: Partitioning this table based on good logical grouping of sourceid, and then timestamp, will help reduce the work required by oracle to verify uniqueness of data, reducing the amount of data that must be cached by oracle, and allow us to handle our "older than 3 month" at a partition level, greatly reducing table and index fragmentation.
Based on our hardware, its going to be about a million dollar hit to upgrade to Enterprise (with partitioning), plus a couple hundred thousand a year in support. Currently I think we pay a whopping 5 grand a year in support, if that, total oracle costs. This is going to be a huge pill for our company to swallow.
What I am looking for guidance / help on, should we really expect partitioning to make a difference here? I want to get that 10x performance difference back we see between a fresh empty system, and our current production system. I also want to limit oracles 10gb / quarter growing need for more buffer cache (the cardinality of sourceid does NOT grow by that much per quarter... maybe 1000s per quarter, out of 2 million).
Also, please I'd appreciate it if there were no mocking comments about using standard one up to this point :) I know it is risky and insane and maybe more than a bit silly, but we make due with what we have. And all the credit in the world to oracle that their "entry" level system has been able to handle everything we've thrown at it so far! :)
Alright all, thank you very much for listening, and I look forward to hear the opinions of the experts.

Hello,
Here is a link to a blog article that will give you the right questions and answers which apply to your case:
http://jonathanlewis.wordpress.com/?s=delete+90%25
As far as you are deleting 80% of your data (old data) based on a timestamp, then don't think at all about using the direct path insert /*+ append */ as suggested by one of the contributors to this thread. The direct path load will not re-use any free space made by the delete. You have two indexes:
(a) unique index (sourceid, timestamp)
(b) index(create time)
Your delete logic (based on arrival time) will smatch your indexes as far as you are always deleting the left hand side of the index; it means you will have what we call a right hand index - In other words, the scattering of the index key per leaf block is certainly catastrophic (there is an oracle iternal function named sys_op_lidbid that will allow you to verify this index information). There is a fairly chance that your two indexes will benefit from a coalesce as already suggested:
           ALTER INDEX indexname COALESCE;This coalesce should be investigated to be done on a regular basis (may be after each 80% delete) You seem to have several sourceid for one timestamp. If the answer is yes you should think about compressing this index
    create index indexname (sourceid, timestamp) compress;
or
    alter index indexname rebuild compress;     You will do it only once. Your index will have a smaller size and may be more efficient than it is actually. The index compression will add an extra CPU work during an insert but it might help improving the overal insert process.
