Table Sequence

Hi All,
I am using Oracle 10g Release 2 & Toad 6.4.7.1 g. In my toad table showing in zigzag way mean the entire table not coming in a alphabetical order. But, no problem in Oracle 10g Release 1.
How can I resolve this problem in Release 2 and what is the possible to show all the tables in alphabetical order?
Regards
Mani

This problem means relative to Toad, no ?

Shared-table-sequence in atg

HI guys,
What is shared-table-sequence attribute for table tab why we should use and when
I have gone through the document but i didnot get exactly
Please any one please give me clear picture on this

Hi,
Like Nitin Dubey said it's used in many to many relationship.
Typically used only in versioned repositories, this attribute is set to an integer between 1-9, which specifies the relationship of this table to other tables in a many-to-many relationship.
In a two-sided many-to-many relationship, the table with the ‘second’ side should set this attribute to 2; the table with the ‘first’ side should set this attribute to 1.
In a versioned repository, set this attribute to 1 for the table that contains the asset_version column; set it to 2 for the table that contains the sec_asset_version table.
For more information look this doc: Oracle ATG Web Commerce - <table>

How do I know about the whole tables, sequences, triggers of the specific D

Hello,
I can check the whole tables of the db users with select * from tab; BUT can I know the whole META DATA of tables, sequences, triggers, procedures of a specific user?

Oracle doesn't expose the metadata just like that but shows it in the various columns of various views based on the object type, for example like for tables, it would be in the user_tables and so on. If you are interested in knowing about the metadata of a specific object, you should use dbms_metadata package.

Table Sequence number

Hi All,
I have a scenario which goes like this:
We have a common table(Table1) in our DB which maintains the sequence numbers(we are not using oracle supplied db sequence).
For every transaction we are using the current sequence number from the table Table1 and put in Table2, while saving
we increment that number by 1 in Table1 for next transactions use. For every transaction the sequence number should be unique.
At any point of time a record with same sequence number should not be inserted in Table2.
In Table2 this sequnce number is not a unique column.
To achieve this, we are checking using view object whether current sequence num already exists in Table2 before saving.
If exists we refresh with new number from Table1. In normal scenario this works fine.
But if concurrent users are accessing, there are cases where same sequence number getting inserted in the Table2
with a time difference of 2 seconds or so(very short span, hence programmatic check fails).
We are unable handle this case using programmatic check of records in table.
Cany any one suggest the best solution possible to tackle this scenario.
Thanks,
Sanjaykar

sanjaykar,
Unless you use locking on the "sequence number generator" table, you WILL at some time get duplicates when two people try to insert at nearly the same time. Sounds like you are going for the infamous "gap-free sequence." My honest and not sarcastic nor facetious suggestion would be to go with a sequence number and abandon your approach.
However, if you insist, you can do this by locking the row in the sequence generator table. You can do this in Oracle by using the FOR UPDATE clause of the SELECT statement like this:
select current_value
from my_sequence_table
where sequence_name = 'foobar'
FOR UPDATEThat will lock the row. You can then increment the number, specify it as your key value, update the current_value in your sequence table and commit. If another user jumps in around the same time, the SELECT FOR UPDATE will block, as the row is already locked. However, I cannot stress enough that if you are looking for a high-performance application, one that lets more than one person work at the same time, this is a horrible idea. Just pop over to http://asktom.oracle.com and search for gap-free sequences to read plenty of long discussions why.
Best,
John

Round table sequence model

Hello All,
I am going to ask your advice.
I have a test station controlled by 2 PCs. The task of this station is to make some electrical tests on electronic sensors. The machine has a round table. There are a load position, a barcode reading position, measuring position 1, measuring position 2, print pos. and unload position. The table rotates when all of the positions finished the current operation. The supervisor PC controls the barcode reading, printing, communication with traceability system. The tester PC controls the test measurement positions.
When the supervisor and the tester PC also send a signal to the test station, the station rotates the table and send a signal about the rotation. Beside this there are some signals from the station which have to be watched. (Emergency stop, station error)
I am going to modify the system.
I am going to make an application based on TestStand which can control this cell and make the measurements only with one PC and one application, since it can improve the stability and robostness of system.
I plan 3 layers.
- User interface where the user can see the state of units, barcodes, actual state of robot and so on.
- TestStand layer: A sequence and a model file which manages the UUTs
- Measurement layer: A CVI dll which makes the measuremens and pass the measured values to the testStand layer.
I think the base of the used sequence model file will the Parallel Model, since max. 6 units are present on the table.
My questions are around the communication between the test station and the PC.
How can i listen to the station signals continously and respond to the signal changing?
Which is the simplest way to start a Testsocket execution after every rotation?
If You have some ideas please do not hesitate to write them.

Extract logic/tables/sequence?

Hello,
I'm curious about the sequence in which different kinds of extraction take place leading to data loading into the BW system (either master- or trans. data).
Is this a correct assumtion:
1. Masterdata: during execution of the info package, the function module (alternatively, a view is used as source and no function module is needed) of the called data source goes into the source tables (ex. MARA), returns the data via the rules of the extract structure (incl. appends/user exits).
2. Trans. data init:during execution of the info package, the function module (alternatively, a view is used as source and no function module is needed) of the called data source goes into the source tables (GLPCA), returns the data via the rules of the extract structure (incl. appends/user exits). After the load, a delta table is generated. Within f.e. SD, you have to generate and fill a setup table in order to be able to load th init.
3. Trans data delta: new postings are added to the delta table (in PCA this happens automatically while in f.e. SD, you have to schedule this procedure) from which the new postings are fetched (via function module or view) on execution of the info package in BW.
Is this the way it works in general? Are there any good documents on this topic? Please mail to [email protected]
Regards,
F C

1. For master data like material, the exractors behave all most the same way.
2. For transaction data, it is diferent for LO comapred to non-LO extractors. for LO transaction data, there are some extra steps you need to do like fillng the set up tables, choosing a delta method, V1,V2, V3.
3. For delta, like I said in 2 above, it is slighly different for LO extractors.
There is lots of info on this subject in SDN. Search with key word LO or cockpit will be very useful.

Oracle jdbc creating a table, sequence and trigger

I'm trying to create a table with a sequence and with a trigger for that sequence. When I do this within Oracle Express edition I have the following SQL statements. Which DO run correctly inside Oracle Express using the same user I log in with JDBC.
CREATE table "TEST" (
"ID" NUMBER(10) NOT NULL,
"NAME" VARCHAR2(20),
constraint "TEST_PK" primary key ("ID")
CREATE sequence "TEST_SEQ"
CREATE trigger "BI_TEST"
before insert on "TEST"
for each row
begin
if :NEW."ID" is null then
select "TEST_SEQ".nextval into :NEW."ID" from dual;
end if;
end;
So now what I do is put each of these into a List of Strings and execute 1 by one like this:
List<String> commands = new ArrayList<String>(4);
commands.add("Create table ...");
commands.add("Create sequence ...");
commands.add("Create trigger...");
st = con.createStatement();
for (String command : commands) {
st.execute(command);
etc...
But I get an error with the trigger statement. "Error with Oracle command: ORA-00942: table or view does not exist"
It seems to me that Oracle has not yet seen the new table at this point. or maybe my user can create tables but not triggers? If that's the case why did it work in the express application itself?
TIA

If that's the case why did it work in the express application itself?No, DDL commands cause an explicit commit. As soon as you invoke them, the change is permanent. If it was a rights problem, you'd get a different ORA error stating that, it won't silently fail.
Lets not assume it is anything difficult, perhaps there is simply a typo in a name somewhere?

Export tables, sequence, and package question

Hi all,
I've export table like: exp username/password file=export.dmp log=export.log tables=A statistics=none.
The export statement above just export only the table "A" structure not the table "A" data. So, how can I move all the data from table "A" to table "B".
How do I export the sequence, and package and its data also?
Thank you very much
Kevin

Can you create a DBlink in order to do the insert into B select * from A.
Also, you can use the SQL*Plus Copy command.
Here are some links for COPY command:

Open Interface Table Sequence

Hi,
We are attempting to build a custom interface for receiving transactions and have the following requirements:
We want to create receiving transaction for the PO line
We want to create a lot for the items in the inventory
We have seen that there is the receiving open interface and also the mtl transaction interface that can probably do this together but want to know the tables to populate. Specifically, is there a link between he receiving transaction's line number and the lot that is created for it ?
Regards.

As Sam said, there is no API for the table - you need to SQL*Loader or inserts (via SQL script or PL/SQL or whatever).
We have a number of processes that generate transactions for Projects where we use Stored PL/SQL based concurrent programs which insert records into PA_TRANSACTION_INTERFACE_ALL.

Cannot change default passivation table/sequence (PS_TXN, PS_TXN_SEQ)

Hi All , i have the following problem:
I'm preparing the ADF/ADF Faces Application to run in failover mode.
One of the problems which i have is that after turning-on the Application Modules failover mode,
the application performance decrease significantly. I found-out that the Application passivates very intensively using (PS_TXN) table
(there are entered more than 30 records per user, only by navigatiing between 2-3 pages).
To increase the performance I'm trying at least to separate the Application Modules to use different tables for passivation.
I'm trying to do that by changing jbo.txn_table_name and jbo.txn_seq_name per different application modules.
However the Application continue using PS_TXN only.
Can somebody give an advice ?
Thanks in advance,
Krasimir

OK, this clears things up a bit.
If you set jbo.dofailover="true" this means that each time an application module is returned to the application module pool in managed state (default state) it gets saved in the db in the ps_txn table. This is the reason why you see so many entries in the table (essentially it's like working without pooling, well, not quite but in a way).
Fail over has the advantage that the state of the module can be reconstructed (even on an other server in the cluster) at any time. Disadvantage is that it take time to store the data in the ps_txn table.
We turned this feature off for all non critical apps as the unscheduled server downtime is <1%. In case of a failure the loss of data is tolerable to our users (their decision).
If I remember correct, you can move all state related stuff into an other db (using an other connection) by setting the jbo.server.internal_connection="conn_to_db" parameter in the configuration of your application. After setting this up the ps_txn table should be created in the other schema.
You should see a better performance this way. If this fulfill your needs is an other question.

Bug jdev 10.1.3 production: sequences showing up as tables

Hello,
A bug I have found: when I generate a script to create database objects (tables & sequences) and choose in the wizard to execute against the DB connection, the sequences are showing up under the "tables" folder in the connection browser (Oracle DB). After I disconnect and re-browse, they are in the correct "sequences" folder.

Could you provide more detailed steps to reproduce?

SEQUENCE TABLE QUESTION

For the sequencing processing, i tell TopLink to use Native Sequencing in my mapping file. When i generate it, TopLink write in the file :
<uses-native-sequencing>true</uses-native-sequencing>
<sequence-table>SEQUENCE</sequence-table>
<sequence-name-field>SEQ_NAME</sequence-name-field>
<sequence-counter-field>SEQ_COUNT</sequence-counter-field>
But my SEQUENCE TABLE name is USER_SEQUENCES (ORACLE SYSTEM TABLE) with SEQUENCE_NAME and LAST_NUMBER as fields.
I can not rename this table in "SEQUENCE" like TopLink want.
How can i do without modify the mapping file ?

I have the proof that TopLink use the sequence-table, sequence-name-field, sequence-counter-field when i use Native Sequencing. TopLink generates :
<uses-native-sequencing>true</uses-native-sequencing>
<sequence-preallocation-size>1</sequence-preallocation-size>
<sequence-table>SEQUENCE</sequence-table>
<sequence-name-field>SEQ_NAME</sequence-name-field>
<sequence-counter-field>SEQ_COUNT</sequence-counter-field>
SEQUENCE is not found when i commit a record -> error
If i modify the XML file with :
<uses-native-sequencing>true</uses-native-sequencing>
<sequence-preallocation-size>1</sequence-preallocation-size>
<sequence-table>USER_SEQUENCES</sequence-table>
<sequence-name-field>SEQUENCE_NAME</sequence-name-field>
<sequence-counter-field>LAST_NUMBER</sequence-counter-field>
USER_SEQUENCES exist, it works !!
Here is my code when i log to my server :
private static ServerSession launchServer() {
if (_server == null) {
String fileName =
Configuration.getInstance().getProperty(
"project.mapping_file");
if (new File(fileName).exists()) {
Project builderProject = XMLProjectReader.read (fileName);
_server = (ServerSession) builderProject.createServerSession (1, 50);
_server.useExclusiveReadConnectionPool(1, 1);
_server.logMessages();
try {
_server.login();
} catch (DatabaseException e) {
} else {
throw new RuntimeException(
"Fichier " + fileName + " n'existe pas...");
} else {
throw new RuntimeException("M�thode static StarServerSession.launchServer() ex�cut�e deux fois...");
return _server;
My code to acquire a client session :
public void open() throws DBException {
try {
clientSession = DBServerSession.server.acquireClientSession();
} catch (DatabaseException e) {
throw new DBException(
DBException.DATABASE_EXCEPTION_ERROR_CODE,
e.getDatabaseErrorCode(),
e.getMessage());

Weblogic Eclipselink Sequence Table Connection Pool Sequence Separate transaction while JTA on main transaction

Hi,
And thanks in advance for your support.
In weblogic 12, managing to get the eclipse link connection sequencing mechanism when one uses Tables for sequencing entity ids seems to be complicated.
QUICK REFERENCE:
http://www.eclipse.org/eclipselink/api/2.5/org/eclipse/persistence/config/PersistenceUnitProperties.html
The concept:
While having EJB, MDBs etc... run on a JEE container, be it glassfish or weblogic, it should be possible to have the main thread transaction be managed as part of JTA global transactions by the contianer.
Namely, pumping messages to JMS queues, persisting entities etc.
Meanwhile, it should be also possible to as the transaction is on going write and update entity ids from sequencing tables.
For this very purpose, eclipse link provides persistence.xml properties, such as the now deprecated eclipselink.jdbc.sequence-connection-pool" value="true", to fullfill this very purpose.
This option greatly avoids dead longs, by allowing eclipse link to fetch a non JTA managed connection, pseudo "two phase locking read table update table" go to the datbase and fetch a new sequence.
The same mechnism under JTA is a disaster. A transaction that creates ten different entities, might do ten reads and updates on this table, while mean while a competing transaction might be trying to do the same. It is guaranteed dead lock with minimal stress on the environment.
Under glassfish, for example, tagging a persistence.xml with :
<persistence-unit name="MY_PU" transaction-type="JTA">
 <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
 <jta-data-source>jdbc/DERBY_DS</jta-data-source>
 <non-jta-data-source>jdbc/DERBY_DS</non-jta-data-source>
 <properties>
 <property name="eclipselink.jdbc.sequence-connection-pool" value="true" />
 </properties>
</peristence-unit>
does miracles, when entities are using TABLE sequencing.
Under weblogic, say you are using the Derby embedded XA driver with two phase commit, deploying the applicaiton immediately leads to:
Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.3.3.v20120629-r11760): org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: java.sql.SQLException: Cannot call commit when using distributed transactions

at org.eclipse.persistence.internal.sequencing.ClientSessionSequencing.getNextValue(ClientSessionSequencing.java:70)
at org.eclipse.persi
While weblogic is right that their might be a distributed transaction ongoing, it is mistaken in the fact tha tthe connection requested by eclipse link for generating the ID should be part of the global transaciton.
Eclipse link provides other ways to attempt to configure the sequencing mechanism, by sating for example a non-jta transaction.
I have attempted also using these properties both withe original data DERBY_DS that uses the XA driver, and later with a new data source i created on purpose to try to work around the sequencing contengy.
For example:

 
This new DERBY_SEQUENCING_NON_JTA is explicitly configured to use a NON_XA driver with global transactions flag set to disabled.
Regardless, the only thing I get out of this is that the application is deployed and super fast, up to the point where i stress it with a system test that introduces some degreee of concurrency, and then I see the dead locks on the sequencing table.
Meaning that the ongoing transactions are holding tight to their locks on the sequencing table.
Is this a known issue?
Is there something I am missing in the configuration?
It really should not be this diffcult to get eclipse link to run its sequence reads and updates on a separate transaction of the main JTA transaction, but so far looks impossible.
Exception [EclipseLink-4002] (Eclipse Persistence Services - 2.3.3.v20120629-r11760): org.eclipse.persistence.exceptions.DatabaseException

Many thanks for your help.

Are you calling the cmp bean code and your new Sql code under a same transactional context?
The following setting
"rollbackLocalTxUponConnClose=true"
will make the connectionpool to call the rollback method on the connection object before keeping it back in the pool. In your sql code if you are calling connection.close() , then your entire transaction will be rolled back.
CMP bean requires a transactional connection while communicating with the database.
What is the sequence of code execution?
I think you must be calling sql code first and then cmp bean code later.
You may avoid this problem in this way. This is my guess based on my understanding on your code execution.
1. set rollbackLocalTxUponConnClose=false
Execute the sql code and cmp code in a single transaction (in a single session bean method with cmt or bmt transaction ). Specify tx.rollback if it is bmt. or call tx.setRollbackOnly() if it is a cmt. In this way you will have control to roll back the transactions.
Hope this helps you.
bmt-> bean managed transaction
cmt-> container managed transaction.

Seshi.
