BC4J under TOMCAT 403 Insert/Update probs
Hi,
My JSP application works fine in JDeveloper 9i (9.0.2). Deployed under Tomcat 4.0.3 everything is ok too except when I try to update/insert records.
I get
Class oracle/jbo/AttributeDef violates loader constraints
The problem seems to be in the SetAttribute datatags in the Row component when updating/inserting.
Anyone had teh same prob? What lib/jar whatever am I missing?
All help will be very much appreciated
Thnx
Eric
Problem solved. I copied all the jar's which should be (according the JDev help) in the lib directory under Tomcat home to the application specific WEB-INF/lib directory.
Regards
Eric

BC4J/UIX Multi Entity insert/update
Hi!
Problem
Is it possible to insert simultaneously both master and detail BC4J row with single UIX page? I would like to use standard UIX if possible with minimal java, but examples with java would be also helpful.
Example
This seems to be a very simple situation. Has anybody solved it?
In my case I have one generic Document table and additional attributes tables for different kinds of documents like for instance LicenseDocument. Those tables are connected with Document table with 1 to 0..1 relationship and their foreign key to the Document table is also their primary key.
I like the way that BC4J Tester works and I don't know how to make UIX work the same way.
When I use BC4J Tester it assigns the Document table inserted but not yet committed rows primary key (DBSequence) column temporary negative values and I can insert child records that are associated with it. After commit the Document primary key is fetched from the database sequence and all the foreign keys in other tables get updated accordingly.
When I use UIX I don't get those temporary IDs and so I can't create child records before the master record is committed. This is not good as I can't roll back the whole creation of the LicenceDocument.
References
I started by posting this topic to UIX forum (BC4J Multi Entity insert/update but maybe someone here knows the solution.
Thanks in advance!
Mihkel N�ges
[email protected]I managed to workaround the issue in UIX by not using DBSequence type but fetching the sequence value in EntityImpl create method (as in Steve Muench's Techiniques demo project http://radio.weblogs.com/0118231/stories/2003/07/11/codeSampleIllustratingVariousBc4jProgrammingTechniques.html ):
DocumentImpl.java:
protected void create(AttributeList attributeList)
super.create(attributeList);
// Do this last so we don't waste any sequence numbers unnecessarily
SequenceImpl seq = new SequenceImpl("DOCUMENT_ID_SEQ",getDBTransaction());
setId(seq.getSequenceNumber());
For some reason the sequence gets asked twice for every row creation. Thats not a big problem, but in the SequenceImpl javadoc this is discussed and as I understand it should not happen. -
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.
java.lang.NullPointerException
oracle.jdbc.ttc7.TTIoac oracle.jdbc.ttc7.TTCAdapter.newTTCType(oracle.jdbc.dbaccess.DBType)
oracle.jdbc.ttc7.NonPlsqlTTCColumn[] oracle ....................
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.

Search criteria for insert/update bdoc
Hi All,
In our set up we have ecc to crm replication of BP. If one goes and checks the extension data of a stuck bdoc it has an Object Task- Insert or Update.
Can someone help me with search criteria so that i can pull out bdocs which have an Insert as the Object task ??
We have search criteria for errored/intermediate state bdocs; for inbound vs outbound; bdoc type etc etc..
Need one based on Insert/Update Task so that any new data replication if stuck with its very first bdoc( Insert type) can be immediately queried.
Regards
AbhinavHello Abhinav,
I do not think that we have such a search criteria to search for BDocs based on the Task Type, which comes under the
data part of the BDoc.
One alternative way is to find out in which table these data gets stored and write a program to fetch the revelent Bdocs.
Hope thisl helps!

Please help!!!
ARFor TomCat 3.2.2 you will need to modify tomcat.bat so that also *.zip is added to the classpath. (look for the line that adds *.jar, duplicate it and change .jar in .zip)
In TomCat 3.2.3 this is changed. (For 3.2.3 they changed Tomcat.bat so it now adds *.* from tomcat/lib to the classpath) -
Custom tag fails to under Tomcat 5.0.16
I have just upgraded to Tomcat 5.0.16 from 4.1.x.
Any JSP page that contains a custom tag fails to build; error message:
org.apache.jasper.JasperException: /jsp/CustomReport.jsp(62,20) Unknown attribute type (String) for attribute name.
The tags work under �Tomcat 4.x�. All other pages build and function correctly.
Specs:
Java 2 version: 1.4.2_03
Tomcat 5.0.16 or Tomcat 4.1.xTry updating your web.xml to use the Servlet 2.4 schema. You will have to change your tld declarations to sit inside the new <jsp-config> tags but see if it works for Servlet 2.4. Could be a backwards compatible bug?

i an developing a bc4j JSP application.
in my form i have html drop down,poplutaed with values by using show value data tag.
The drop down box contains "decription" field.
now while inserting/updating,i want to find the corresponding desc_id and insert /update this desc _id in another table.
how do i do this?
Please help
MonaliTo update/insert data, you can use ExecuteSQL data tag.
Like example:
<%
String desc = request.getParameter("desc");
String desc_id = request.getParameter("desc_id");
%>
<jbo:ExecuteSQL appid="id" > update table set desc=<%= desc %> where desc_id=<%= desc_id %>
</jbo:ExecuteSQL>
Hope this help. -

cannot be the full story you tell. The exception is thrown in the context of a prepareForDML, which is called on entities for the Create / Update and Delete use case. I also see a failed rollback. So there must be something you do before this happens during a page refresh

Stats on Inserts/Updates/Deletes
What's the best way to figure out how many insert/update/delete transactions my 10g Grid is processing over a given period (e.g. an hour) of time?
I want to come up with an automated procedure for collecting these stats (and possibly logging them
to a file).
I have Grid Control running, but in poking around under 'Performance' I don't see any metrics like this.http://hostname:port/em

Array Insert/Update/Select in JDBC
I've been using array processing in ODBC, OCI, and Pro*C for years and desperately need to do so in JDBC. I've thus far been unsuccessful and am beginning to doubt that it's supported which to me is unfathomable. I've likewise found many like inquiries on the net - none of which were addressed. There have been many respondants who don't undertstand what array processing is and mistake it for batch SQL statements. They are not the same. Batched SQL statements are seperate statements which are executed in a single call to the database engine. What I'm taking about is using a prepared statement and binding primitive arrays to the statement. A single statement is executed and the contents of the arrays passed to the database. I've conducted tests years ago and array insert/update is many times faster than batch statements. Does anyone know whether or not JDBC supports array processing? If anyone's interested, I can provide snippets via email which illustrate how this is done in ODBC and other API's.
Thanks.You referred me to
http://java.sun.com/products/jdbc/download.html. The
only reference I found to arrays were SQL Arrays - not
what I'm talking about. See prior C/ODBC snippet. Do
you know how to do this in JDBC?You are talking about passing an array as a single parameter to and from the underlying database correct? (And that has nothing to do with batch processing.)
If so in section 16.4 "Array Object"..... looking at that section gives the following reference....
The Array object returned to an application by the ResultSet.getArray and
CallableStatement.getArray methods is a logical pointer to the SQL ARRAY
value in the database; it does not contain the contents of the SQL ARRAY value.
The above has nothing to do with batch processing (although presumably one could use it in a batch process but then one can use String as well.)
Of course perhaps there is something in there that says that only applies to batch processing. If so could you please point out the section and quote the text. -
Confirmation before insert, update or delete
Hi,
I want to create something like alert which before insert or update or delete ask me to do that. I mean that if i am going to insert a record, it will ask me "Are you sure you want to insert record", and provide two buttons OK and cancel. If i press cancel then it will not let me do that. I tried confirm function of javascript but even when i clicked cancel it went to insert the record. How can i achieve this functionality.
ThanksYOU 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..

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

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

Inserted | updated | deleted | merged
Hello,
If a table has been set to update/insert and a row arrives with a matching column then the corresponding row in the target table is updated. In the job details window shouldnt it show a 1 under the updated section. My question really is, what does the merged tab indicate ?
ThanksHi,
As per my knowledge
If map runs in row based mode-- insert,update tabs are filled
If map runs in set based mode- merge will come
Row Based mode: In the pl/sql pkg generated by the map
insert and update operation will happen for each row
For insert/update option --First insert statement will run if the record exists then exception will come , then in the exception block update statment will be there and thee the record will be udpated..
For update/insert option -- First it tries to update the record.. if it doestnt find the record it raises an exception , in the exception block insert statment will be ther
that will insert the record..
In Set based Mode:
Instead of separate insert/update statements one merge stament will be there it will run...
So set based mode is faster than row based mode..
If any errors comes, then its difficult to find the source record causing the error in set based mode as it is in merge statment
but it is easy in row based as it will do insert/update for each record --- each record will be inserted in the audit tables.
Hope this will give u an idea
Than you -
