Batch Insert Using Oracle

I am having a performance issue with network traffic. Can anyone tell me how to if possible to make batch inserts to a Oracle Database.
Thanks

Absolutely, It's called batching.
There is a code sample in
ORACLE_HOME/jdbc/demo/samples/oci8/basic-samples/SetExecuteBatch.java
The feature is not specific to the OCI driver, it works with the KPRB driver within JServer.

Batch Updates Using Oracle

Hi,
We are currently having problems saving data using Weblogic 6.1 sp1 and Oracle
8.1.6. we are using Weblogic JDBC Drivers for Oracle. The data we are saving is to
the extent of 25-50,00 records. When we are trying to this we are getting transaction
timeout errors since this saver process is taking more than 30 seconds which is out
rimeout limit.
Can we do this using Batch updates?? Any code snippets or pointers will be grealty
appreciated.
Thank YOu,
Sanjeev

Can you be more specific?
- What do you want to do exactly?
- What are your OS and Reports versions?
At first, it sounds a bit strange to use Reports for batch updates. A pl/sql procedure may be more suitable.
You can schedule a report in several ways, e.g. via CRON on Unix (see RWRUN command in the 9iDS Help)).
You can do the same via the database using the SRW package (see http://download-west.oracle.com/docs/html/A92102_01/pbr_evnt.htm#1005558 )
You can use the Reports Queue Manager.

Batch insert from object variable

Any way to do this excluding the foreach loop container? I have millions of rows and if it goes through them 1 by 1 it will take hours maybe days. How can you do a batch insert from an object variable without putting the sql task inside
a foreach loop container?
thanks,
Mike

I know how to use the dataflow task but it will not work with what I am trying to do as far as I know. The script I am running is against a netezza box that creates temp tables and then returns a data set that I store in an object variable.
I then want to take the data from that object variable and batch insert it into a table. The only way I can see this being done is by looping through the record set in a foreach loop while mapping the fields to variables and inserting records one
at a time like I am doing in the screenshot above. This takes way to long to do. I am trying to figure out a way to do a batch insert using the data in this object variable. Is this possible? I am using SSIS Version
10.50.1600.1
thanks,
Mike
Hi Mike,
Provide more details why you cannot use the data flow task for the processing.
Let me repeat . Loading millions of records in object variable will not work.

You'll get a faster, more effective response to your questions by including as much relevant information as possible upfront. This should include:

With APEX we're fortunate to have a great resource in apex.oracle.com where we can reproduce and share problems. Reproducing things there is the best way to troubleshoot most issues, especially those relating to layout and visual formatting. If you expect a detailed answer then it's appropriate for you to take on a significant part of the effort by getting as far as possible with an example of the problem on apex.oracle.com before asking for assistance with specific issues, which we can then see at first hand.

Can select, but cannot insert into oracle tables using php.

I am having trouble inserting data into a tables in oracle using PHP. I can insert into the tables using baninst1, but nothing else. I can't even insert using the tables' owner. Every time I try I get the ORA-00492 error of table or view does not exist. However, I can run a select statement just fine. So far, baninst1 is the only user that can actually do inserts. I've triple checked all the table grants and everything is fine. Also, I can copy/paste the exact insert statement into SQL*Plus and it works with the correct user. It doesn't have to be baninst1. I've tried everything I can think of. I've tried putting the table name in quotes, adding the schema name to the table, checking public synonyms, but everything appears to be ok. I would greatly appreciate any suggestions others may have.
I'm using PHP 5.2.3 with an oracle 9i DB.

Here is the code that doesn't work. It works only with baninst1, no other username will work and all I do is change the my_username/my_password to something different. This is one example function where I try to do an insert, but it doesn't work on any of the tables I try.
Thanks for looking.

BLOB insertion in Oracle 10g database using ojdbc14 (10g drivers)

Hello!
I have a situation where I am trying to insert a blob data into oracle 10g database using oracle thin
10g drivers, ojdbc14.jar in weblogic 8.1 sp2. I have the following error happening very intermittently.
java.sql.SQLException: OALL8 is in an inconsistent state.
And this is leading to the "No more data to read from socket" error when I am trying to
insert the BLOB into the database. I have gone through the bug list of SP2 and have realised there is the
following issue fixed in SP3.
CR124933
An Oracle BLOB sometimes used a pooled connection after the connection pool determined that
the connection was available for reassignment.
Code was added to ensure the BLOB is completely processed before closing the pool connection or
ending the transaction.
I believe the problem arises when we try to insert BLOB into database using a refreshed connection
from the pool.We have upgraded weblogic 8.1 from SP2 to SP4 service pack inorder to come over the above problem.
But this still continues to behave intermittently.
We put ojdbc14.jar in our classpath and Weblogic startup classpath looks like the following :-
WLS_CLASSPATH=${WLS_DOMAIN_DIR}/appslib/server.jar:$PRE_CLASSPATH:${WLS_WEBLOGIC_HOME}/server/lib/weblogic.jar:
${WLS_WEBLOGIC_HOME}/server/lib/ojdbc14.jar:${WLS_WEBLOGIC_HOME}/server/lib:${WLS_JAVA_HOME}/lib/tools.jar:
${WLS_JAVA_HOME}/jre/lib/rt.jar:${WLS_WEBLOGIC_HOME}/server/lib/webservices.jar:${WLS_CONFIG_DIR}:
${WLS_CUSTLIB_DIR}:${WLS_BIN_DIR}:$POST_CLASSPATH
export WLS_CLASSPATH
CLASSPATH=${WLS_CLASSPATH}:${APP_CLASSPATH}
export CLASSPATH
After upgrade to SP4, there are new ojdbc14_g.jar(debug jar) and orai18n.jar jars in the ${WLS_WEBLOGIC_HOME}/server/ext/jdbc/oracle/10g directory added.
Please let me know if I need to update classpath with the new 10g jars in the ext/lib directory or any suggestions
to insert BLOB using the ojdbc14 10G drivers, Weblogic 8.1 environment would be appreciated.
Following is the stack trace of the errors that I recieve:
<Oct 6, 2005 1:29:36 PM EDT> <Error> <JDBC> <BEA-001112> <Test "select count(*) from DUAL" set up for pool

Here is my code in C#, can you guys help me with insert statement:
string oradb = "Data Source= oraDB;User Id=sm;Password=mypassword;";
OracleConnection conn = new OracleConnection(oradb);
conn.Open();
OracleCommand cmd = new OracleCommand();
cmd.Connection = conn;
cmd.CommandText = "Insert into USER.EMPLOYEE VALUES (tbEmployeeName.Text, lbEmployeeGender.Text)";
int rowsUpdated = cmd.ExecuteNonQuery();
if (rowsUpdated == 0)

Thanks!Hi,
You'll want to read up on using parameters (also known as bind variables) - these are critical for scalability in an OLTP-type system and helping guard against SQL Injection attacks. There's many sources out there, but here's a link to the Parameter Binding section in the ODP.NET Developer's Guide which is probably a good thing to become familiar with:
http://docs.oracle.com/cd/E11882_01/win.112/e23174/featOraCommand.htm#i1007242
Here's your sample using bind variables:
string oradb = "Data Source= oraDB;User Id=sm;Password=mypassword;";
OracleConnection conn = new OracleConnection(oradb);
conn.Open();
OracleCommand cmd = new OracleCommand();
cmd.Connection = conn;
// Perform insert using parameters (bind variables)
cmd.CommandText = "Insert into USER.EMPLOYEE VALUES (:1, :2)";
// Here's one way to use parameters aka bind variables:
// Create parameters to hold values from front-end
cmd.Parameters.Add(new OracleParameter("1",
                                       OracleDbType.Varchar2,
                                       tbEmployeeName.Text,
                                       ParameterDirection.Input));
cmd.Parameters.Add(new OracleParameter("2",
                                       OracleDbType.Varchar2,
                                       lbEmployeeGender.Text,
                                       ParameterDirection.Input));
int rowsUpdated = cmd.ExecuteNonQuery();
if (rowsUpdated == 0)
MessageBox.Show("Record not inserted");
else
MessageBox.Show("Success!");
conn.Dispose();
// don't forget to perform any clean-up as necessaryNote that I've just typed this into a text editor and not verified, so please excuse any typos you may find.
Also, I've allowed the default of OracleCommand.BindByName=false as I prefer that, though others certainly prefer setting it to "true". See the docs for what this means if you are not sure.

Bulk insert into oracle using ssis

Hi ,
Can someone please suggest me the way to Bulk insert data into oracle database? I'm using oledb which doesnt support bulk insert into oracle.
Pls note I cant use Oracle ATTUnity as it requires enterprise edition but i have only Standard edition and hence that option is ruled out.
Is there any other way that I can accompolish BULK insert?
Please help me out.
Thanks,
Prabhu

Hi Prabhu,
I am very late to help you solve the query but following is the solution to 'Bulk Insert into Oracle' that worked for me.
To use below code for SSIS 2008 R2 in a
Script Task component you would need following API references.
Prerequisites:
1. C:\Program Files (x86)\Microsoft SQL Server\100\SDK\Assemblies\Microsoft.SQLServer.DTSRuntimeWrap.dll
2. Install "Oracle Data Provider For .NET 11.2.0.1.0" and add a reference to
Oracle.DataAccess.dll.

How to insert data from *.dmp file to oracle 11g using Oracle SQL Develope

hi
i backup my database using PL/SQL developer and made *.dmp file
how to insert data from *.dmp file to oracle 11g using Oracle SQL Developer 2.1.1.64
and how to make *.dmp file from sql*plus ?
thanks in advance

Pl/Sql developer has a config window, there you choose the exec to do the import/export.
Find it and his home version, it may be exp or expdp, the home version is the version of the client where the exp executable is.
Then use the same version of imp or impdp to execute the import, you do not need to use Oracle SQL Developer 2.1.1.64. If you want to use it, you must have the same version in the oracle home that exp/imp of sql developer use.

Big performance drop migrating to Kodo 4.1 (Why would Kodo refuse to batch inserts in certain tables)

Hello,
While migrating from Kodo 3.4 to Kodo 4.1, I noticed significant drop in
insert performance. I traced it down to some strange batching behavior.
While most of the PCs were committed with batched inserts one particular
class refused to batch and would insert row by row resulting in 10 times
performance drop.
There is nothing special about the class. Its hierarchy is mapped on base
its table except for one of the lowest members which is mapped vertically.
Thank you very much

This case is being handled elsewhere, but for the benefit of others:
Kodo 4 works around a date/timestamp batching bug in some Oracle drivers

Abe could you get a bit deeper into it ?
It sounds like kodo 3 was batching that rows and had no problem with it ?
We only ship with the suggested oracle driver 10.2.0.1.0.
50% of our customers use oracle, so it would be a pity if performance
drops.
Alex ... it sounds like you successfully migrated to kodo4.
Could you give a short summery on how 'difficult' it was in the end ?
From the docs it sounds very easy (except the sentence 'Many
confniguration
properties and defaults have changed.') but from the newsgroups it sounds
as if
you'd struggle a bit.
I'm about to schedule our migration for the first quarter of 2007 and any
hint
helping use to estimate the time will help us.
If you compare with migration from kodo 2 to 3 ... is it easier or worse ?

How to control number of records in batch insert by eclipselink

Hi,
We are using eclipselink(2.2) to persist objects and we use following configuration -
<property name="eclipselink.jdbc.batch-writing" value="Oracle-JDBC" />
<property name="eclipselink.jdbc.batch-writing.size" value="5" />
however the number of records inserted is much more than 5( I have seen 5000 records being inserted ). How can we control the number of records inserted once?
Thanks.

Binding can be configured using the "eclipselink.jdbc.bind-parameters" property, and is on by default - it should be on for jdbc batch writing.
Batch writing defaults to 100 statements, so I am not sure why it would include all statements in one batch unless it is not batching at all. If you set the logs to finest or all it should print of the values it is using for each property, and also show the SQL and statments it is executing. Can you turn on logging and post portions of the logs, particularly the part showing the transaction in question (though maybe only 6 lines of consecutive inserts).
Logging is controlled through the "eclipselink.logging.level" properties.
Best Regards,
Chris

Are batch inserts supported in cx_oracle?

Oracle's JDBC package provides for batch inserting to increase performance. I've used it in writing an ETL tool in Java. I would like to do the same in Python, but I can't find anything that mentions the same batch insert capability in cx_oracle. Any ideas?

Have you tried http://www.oracle.com/technology/pub/articles/prez-python-queries.html?
Look for "Many at Once" section.
