Response.write after insert/update
Hi
Could anyone please show me how to do a response.write message on the page after insert/update?
Wondering especially about the placement and the syntax of the response.
DWCS5, Access, Asp
Christian
I'm sorry to say I don't know how to test values in ASP, have just started to use it.
I didn't get it to work so I threw away the code and went for an ordinary text response on a second page.
Might as well get a book and read up on it

Bc4j bug at refresh after insert / update
having a table and a trigger on it that fills an attribute
in a 9i db. one can take the scott/tiger emp table and use the
following trigger:
create or replace trigger t_bri_emp
before insert on emp
for each row
declare
v_no number(7,2);
begin
select user_SEQ.nextval*100
into v_no
from dual;
:new.sal := v_no;
end;
then creating a bc4j project with an entity object based on this table (emp)
and a view object based on the created entity object.
!!!! when you create the bc4j project you must set the SQL Flavor to SQL92 or OLite
when you set the attribute settings, for the attribute the trigger is on (sal),
to refresh after insert / update or both in the entity object you get a
null pointer when you try to insert a new row and commit.

all can be reproduced just useing the wizard and start the bc4j project with the tester
any workaround ??Sven:
I looked into your issue. It turns out your problem is caused by a bug in the system (bug #2409955).
The bug is that for non-Oracle SQLBuilder, we are not processing refresh-on-insert and refresh-on-update attributes correctly. We end up forming an invalid SQL statement and the JDBC driver gives the obscure NullPointerException.
Thus, until 9.0.3, you should not use refresh-on-insert/update attributes on a non-Oracle SQLBuilder.
If you need the refresh-on-insert/update attribute, here is a possible workaround:
1. Whenever you invoke the tester, on the first panel, click on the 'Properities' tab. In the list of properties, you should find one for 'jbo.SQLBuilder'. It will say 'SQL92'. Remove it, so that it is empty. Run test tester. Then, the tester will use Oracle SQLBuilder which will handle refresh-on-insert/update attributes correctly for you.
2. For switching between Oracle SQLBuilder and SQL92 SQLBuilder, you can try the following:
2a) Locate bc4j.xcfg and your Project??.jpx under your 'src' directory.
2b) Make copies of these files.
2c) Edit them so that you have one set for Oracle SQLBuilder and one set for SQL92 SQLBuilder. For Oracle SQLBuilder, make sure these files do NOT have entries like:
<jbo.SQLBuilder>..</jbo.SQLBuilder> in bc4j.xcfg and
<Attr Name="_jbo.SQLBuilder" Value="..." /> in Project??.jpx
When there is no jbo.SQLBuilder entry, BC4J will default to Oracle.
For SQL92, make sure you have
<jbo.SQLBuilder>SQL92</jbo.SQLBuilder> in bc4j.xcfg and
<Attr Name="_jbo.SQLBuilder" Value="SQL92" /> in Project??.jpx.
Before you run, decide which SQLBuilder to use (for 9.0.2, with retrieve-on-insert/update attrs, you have no choice but to use Oracle SQLBuilder) and copy these files into your class path, e.g.,
<jdev-install-dir>\jdev\mywork\Workspace1\Project1\classes
When you get 9.0.3, then you should be able to switch between Oracle and SQL92 SQLBuilders freely.
Thanks.

(Automatic) Refresh of Cached object after insert/update
Hi,
(I am using Toplink 9.0.3 against an Oracle Database)
I am inserting and updating records in the database through objects registered in a TopLink UnitOfWork. I happen to know that certain database columns will get a (changed) values because of Database triggers.
Is it true that the only way to get these changed values reflected back to the TopLink cache is by explicitly executing a
session.refreshObject();
call for every object changed in the UnitOfWork?
Is there no way to inform TopLink (for example through the descriptors for the relevant classes) that for certain classes after the insert/update an automatic synchronization with the database must be performed?
I have not been able to find such a setting, but I may have overlooked it - I hope I did.
Thanks for your help,
Lucas Jellema (AMIS)In this case use a postMerge event -- it will get called after the merge of the cache and then you could update the object explicitly.
Ultimately, the way to achieve the behavior you're looking for is events or refreshing.

Refreshing the RowSetBrowser webbean after insert/update(?)
How do I refresh the RowSetBrowser web bean after inserting or updating and committing a record thru the EditCurrentRecord web bean?
I am unable to see the new record added in the RowSetBrowser unless I close the browser and re-enter.
Any advice would be appreciated!
nullafter you call to iniatialize() in the DWB, you can refresh the cache by calling
<%
dbw.getRowset().executeQuery();

Need user response(confirmation) before Insert, update or delete
Hi,
I want that before insert or update or delete etc., an alert is shown to the user and if the user click OK button then that action is performed on database otherwise not. I wrote following javascripts in a user interface template and then called this function but it did not work
function confirm_Modification_delete ()
if (confirm("Are you sure you want to remove this record?"))
return true;
else
alert("You click Cancel")
return false;
in the same way i also created insert or update alerts but when i clicked cancel even then they perform the insert or update or delete. How can i correct these scripts or get this functionality.
Thanks
Muhammad Ejaz
nullYOU CAN ADD THE FOLLOWING JAVASCRIPT CODE UNDER THE "onClick" EVENT FOR THE INSERT/UPDATE/DELETE BUTTONS...
var x=window.confirm('Do you want to proceed?');
if (!x)
return false;
IT WORKS FOR ME
I HOPE IT HELPS..

I need to write a trigger that if some columns of the master table have changed, the trigger will first insert the change to a copy table. Later on, if there are more changes to the master of the same row, it will compare the new value to the old value and delete the same row in the copy table and insert the latest change. I have wrote the following trigger. Some how when I run it, it has compilation error. Does anyone have any idea on how should I approach this?
create or replace trigger TRITON.AFTER_INSERT_UPDATE_ITM001100after insert or update on TRITON.TTIITM001100for each rowdeclarev_reflag char(1);beginv_reflag:='0';if (:new.T$ITEM != :old.T$ITEM or :new.T$DSCA != :old.T$DSCA) then

This is simple SQL statements, not PL/SQL.
Use EXECUTE IMMEDIATE for executing it.

No database update after insert / update
Dear all..
I have created a small report for storing additional invoice text into a z-table. These invoice text could have the lenght of 2560 character and are needed for EDI transmission.
Directly after saving - I can view them. After some hours I am always getting empty fields wenn I try to view the data. ... for me it looks like that the table entries are buffered but nor really stored into database. Does a commit work solves this problem ?
Thanks in advance
Jürgenhi,
you say :
Directly after saving - I can view them.
how? with se16 or program?

Using Database Change Notification instead of After Insert Trigger
Hello guys! I have an after insert trigger that calls a procedure, which in turn is doing an update or insert on another table. Due to mutating table errors I declared the trigger and procedure as autonomously transactional. The problem is, that old values of my main tables are inserted into the subtable since the after insert/update trigger is fired before the commit.
My question is how can I solve that and how could I use the change notification package to call my procedure? I now that this notification is only started after a DML/DDL action has been commited on a table.
If you could show me how to carry out the following code with a Database Change Notification I'd be delighted. Furthermore I need to know if it suffices to set up this notification only once or for each client seperately?
Many thanks for your help and expertise!

Sebastian

Updating row after insert that causes trigger
Hi,
I have a table which one of the columns is a sequence number which each time a new row is written I want to automatically write to this sequence column the latest number (which is maintained using an Oracle sequence). I decided to use a trigger which works great:
CREATE OR REPLACE TRIGGER pre_insert_trg before insert ON INCOMING
for each row
BEGIN
SELECT INCOMING_SEQ.NEXTVAL
INTO :new.SEQ
FROM DUAL;
END;
The problem is I have many multi-threaded processes writing to this table and the sequence number gets allocated before the row is committed which means although thread 1 may write first it may commit after thread 2 which has a later sequence number which has the result that sequence number 2 may be shown before 1. The problem is much larger when dealing with many threads with 100's of messages a second and so I would prefer the seq to be added AFTER the insert (once committed), e.g.
CREATE OR REPLACE TRIGGER post_insert_trg after insert ON INCOMING
for each row
BEGIN
SELECT INCOMING_SEQ.NEXTVAL
INTO :new.SEQ
FROM DUAL;
END;
Trying to create this trigger results in a "ORA-04084: cannot change NEW values for this trigger type". Is there a way to update a column for the row which caused the trigger? If I try and remove the :new. I then get errors when inserting about mutating table (which I understand the DML locking but need a way round)
Many thanks,
JohnOff hand I think the only way you can do what you say you want to do is to replace the sequence with a code table. A transaction locks the code table, gets the next value from it and unlocks the code table at the end of the transaction. This ensures that the sequence number is always assigned in transaction completion order (or rather the transactions always complete in sequence assigned order). It is basically what java does with its synchronize statement.
The only drawback with this approach is that it completely shags the performance of the sort of multi-threaded environment you've just described. :P
So you need to decide what's more important: having stuff inserted into a queue in sequence order or having a multi-threaded system running quickly. I really don't see how you can acheive what you're attempting in a genuinely concurrent environment; you'll have to introduce an artificial serialism (ie bottleneck) somewhere.
If you do crack this please tell me how: I would be interested in ordering multiple AQs in the fashion you described.

Extremely slow inserts/updates reported after HW upgrade...
Hi gyus,
I'll try to be as descriptive as I can. It's this project in which we have to move circa 6 mission critical (24x7) and mostly OLTP databases from MS Windows 2003 (DB on local disks) to HP-UX IA (CA metrocluster, HP XP 12000 disk array) - all ORA10gR2 10.2.0.4. And everything was perfect until we moved this XYZ database...
Almost immediately users reported "considerable" performance degradation. According to 3rd party application log they get almost 40 secs. instead of previously recorded 10.
We, I mean Oracle and HP specialists, haven't noticed/recorded any significant peeks/bottlenecks (RAM, CPU, Disk I/O).
Feel free to check 3 AWR reports and the init.ora at [http://www.mediafire.com/?sharekey=0269c9bc606747b47f7ec40ada4772a6e04e75f6e8ebb871]
1_awrrpt_standard.txt - standard workload during 8 hours (peek hours are from 8-12AM)
2_awrrpt_2hrs_ca.txt - standard workload during 2 peek hours (8-10)
3_awrrpt_2hrs_noca.txt - standard workload during 2 peek hours (10-12) with CA disk mirroring disabled
Of course, I've checked the ADDM reports - and first, I'd like to ask why ADDM keeps on reporting the following (on all database instances on this
cluster node):
FINDING 1: 100% impact (310 seconds)
Significant virtual memory paging was detected on the host operating system.
RECOMMENDATION 1: Host Configuration, 100% benefit (310 seconds)
Is it just some kind of false alarm (like we use to get on MS Windows)? Both nodes are running on 32gigs of RAM
with roughly more than 10gigs constantly free.
Second, as ADDM reported:
FINDING 2: 44% impact (135 seconds)
Waits on event "log file sync" while performing COMMIT and ROLLBACK operations
were consuming significant database time.
we've tried to split CA disk mirroring, using RAID 10 for redo log file disks etc. etc. No substantial performance gain was reported from users (though I've noticed some in AWR reports).
Despite confusing app. users' feedback I'm nearly sure that our bottleneck are redo log file disks. Why? Previously (old HW) we had 1-3 ms avg wait on log file sync and log file parallel write and now (new HW, RAID5/RAID10 we've tested both) - it's 8 ms or even more. We were able to get 2ms only with CA switched off (HP etrocluster
disk array mirroring).
And that brings up two new questions:
1. Does redo log group mirroring (2 on 2 separate disks vs. 1 on 1 disk) have any
significant impact on abovementioned wait events? I mean what performance gain
could I expect when I drop all "secondary" redo log members?
2. Why do we get almost identical response times when we run bulk insert/update tests (say
1000000 rows) against old and new DB/HW?
Thanks in advance,
tOPsEEK

SQL merge and after insert or update on ... for each row fires too often?
Hello,
there is a base table, which has a companion history table
- lets say USER_DATA & USER_DATA_HIST.
For each update on USER_DATA there has to be recorded the old condition of the USER_DATA record into the USER_DATA_HIST (insert new record)
- to have the history of changes to USER_DATA.
The first approach was to do the insert for the row trigger:
trigger user_data_tr_aiu after insert or update on user_data for each rowBut the performance was bad, because for a bulk update to USER_DATA, there have been individual inserts per records.
So i tried a trick:
Instead of doing the real insert into USER_DATA_HIST, i collect the USER_DATA_HIST data into a pl/sql collection first.
And later i do a bulk insert for the collection in the USER_DATA_HIST table with stmt trigger:
trigger user_data_tr_ra after insert or update on user_dataBut sometimes i recognize, that the list of entries saved in the pl/sql collection are more than my USER_DATA records being updated.
(BTW, for the update i use SQL merge, because it's driven by another table.)
As there is a uniq tracking_id in USER_DATA record, i could identify, that there are duplicates.
If i sort for the tracking_id and remove duplicate i get exactly the #no of records updated by the SQL merge.
So how comes, that there are duplicates?
I can try to make a sample 'sqlplus' program, but it will take some time.
But maybe somebody knows already about some issues here(?!)
- many thanks!
best regards,
FrankHello

Capturing value in after insert or update row level trigger
Hi Experts,
I'm working on EBS 11.5.10 and database 11g. I have trigger-A on wip_discrete_jobs table and trigger-B on wip_requirement_operations table.When ever i create discrete job, it inserts record in both wip_discrete_jobs and wip_requirement_operations.
Note:2 tables are like master-child relation.
Trigger-A: After Insert.Row Level trigger on wip_discrete_jobs
Trigger-B:After Insert,Row Level trigger on wip_requirement_operations
In Trigger A:
I'm capturing wip_entity_id and holding in global variable.
package.variable:=:new.wip_entity_id
In Trigger B:
I'm using the above global variable.
Issue: Let's say i have create discrete job,it's wip_entity_id is 27, but the global variable is holding the previous wip_entity_id(26),not current value.It looks like before trigger A event is complete, trigger B is also in process, i think this could be the reason it's not storing the current wip_entity_id in the global variable.
I need your help how to have the current value in the global variable so that i can use that in the trigger B.
Awaiting response at the earliest.

ThanksMy head hurts just thinking about how this is being implemented.
What's stopping you from creating a nice and simple procedure to perform all this magic?
Continue with the global/trigger magic at your own peril, as you can hopefully already see ... nothing good will come from it.
