Accessing Postgres from Oracle using DG4ODBC and psqlodbc very slow

I have set up DG4ODBC on a Windows 2003 32-bit 11g Oracle database to access a Windows 2008 64-bit 9.1 Postgres database, using the psqlodbc driver (32-bit).
I am able to issue queries, but they are very slow. The reason is that the where clause of the query is being removed somewhere along the line (I have seen the actual queries run by Postgres using pgAdmin server status screen), and all the rows in the table are retrieved from Postgres. Naturally with tables bigger than a few rows that means doing a full table scan in Postgres, as well as transferring lots of bytes through the network.
For instance, if I query from Oracle like this: select * from "dps_user"@pg where "id" = '2423', the sql run at Postgres is this: select * from dps_user, which retrieves all rows on the table! When I get the query result in Oracle, I only get the row with id 2423, so I assume that Oracle gets the whole table, and does the filtering at its end.
In a 32-bit Windows XP separate machine I have set up the same psqlodbc driver, and I have run the same query using Microsoft Query. In this case, the query run in Postgres contains the where clause, and therefore it is much faster because a unique index scan is performed in Postgres, and only one row is transferred back to Microsoft Query.
Could you help me, please?
Thanks a lot,
Carlos

Hi Mike,
Thanks a lot for your help. The gateway version must be 11.2.0.3 since the Oracle database has patchset 11.2.0.3 applied.
This is the ini file once I changed the trace level:
HS_FDS_CONNECT_INFO = pg
HS_FDS_TRACE_LEVEL = 255
I tried this query:
select *
from dps_user
where id = 'W106606';
Where dps_user is a view on the Oracle database which translates to this:
CREATE OR REPLACE FORCE VIEW dps_user (ID,
login,
first_name,
last_name,
lastactivity_date,
registration_date,
email,
email_status,
receive_email
AS
SELECT "id", "login", "first_name", "last_name", "lastactivity_date",
"registration_date", "email", "email_status", "receive_email"
FROM "dynamo_web"."dps_user"@pg.es.lladro.com;
The generated trace file is:
Oracle Corporation --- JUEVES MAY 09 2013 18:13:35.968

11.2.0.3.0

Accessing mysql database from oracle using dg4odbc

I've been trying to create a database link from a MySQL database to Oracle using the Oracle dg4odbc gateway. I downloaded and installed DataDirect's ODBC package which includes mysql ODBC library (ddmysql24.so) and a generic ODBC libary (libodbc.so). After creating the DSN in odbc.ini, I tested it and it can connect to the mysql database. Then I created the init{SID}.ora file in hs/admin directory, added dg4odbc lines in the listener.ora, and added lines in tnsnames.ora. Then I tnspinged the new SID with success. Finally, I created the database link. However, when I tried to access the database link using the commands "select * from mdl_user@moodle;", I got the ORA-28500 error like the following:
ERROR at line 1:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[DataDirect][ODBC 20101 driver][20101]You have an error in your SQL syntax;
check the manual that corresponds to your MySQL server version for the right
syntax to use near '"mdl_user"' at line 1
ORA-02063: preceding 2 lines from MOODLE
My mysql database is utf8 by default. Do I have to use latin1?
It seems to me that the dg4odbc translates the sql commands incorrectly (having double quotes around the selected table).
Any help is greatly appreciated.
Jeffrey

The syntax error occures for example when MySQL isn't running in ANSI mode and thus does not allow double quotes around the objects. DG4ODBC 11.1.0.6 by default always adds double quotes to table/column/view names.
A quick test to check if you hit the double quote issue would be to set the MySQL DB into ANSI mode:
- Open SQL*Plus
- execute:
DECLARE
ret integer;
c integer;
BEGIN
c := DBMS_HS_PASSTHROUGH.OPEN_CURSOR@moodle;
DBMS_HS_PASSTHROUGH.PARSE@moodle(c, 'SET SESSION SQL_MODE=''ANSI_QUOTES'';');
ret := DBMS_HS_PASSTHROUGH.EXECUTE_NON_QUERY@moodle(c);
dbms_output.put_line(ret ||' passthrough output');
DBMS_HS_PASSTHROUGH.CLOSE_CURSOR@moodle(c);
END;
- Now run your select statement
=> if it now works, you can permanently change the MySQL config to be ANSI compliant or you can apply the 11.1.0.7 patchset to DG4ODBC.

How to insert and view images from oracle using jsf

Can anyone please give me some code example or link of article explaining that how can i insert and view images to/from oracle using jsf?
Thanks in advance.

You mean you want to view image data stored in the database, right?
Create a servlet that streams the image data to the response (setting the appropriate content-type), then reference this servlet in your img tag. Here is an example:
http://balusc.blogspot.com/2007/04/imageservlet.html
Storage is something different. What exactly don't you understand there? Perhaps you want a file upload component?

After APTV and itunes upgrade on mac, streaming from itunes to Apple TV is very slow.

After APTV and itunes upgrade on mac to latest on 02/15, streaming from itunes to Apple TV is very slow. even 5 mins song takes 10-15 mins to start. Netflix/Youtube work fine on Apple TV. restarted Mac, router, modem, appletv. reset Appletv to factory setting and re-start.

Apple TV 2 does not appear in iTunes (exception being when connected via micro-usb for restore) as it has no sync capabilities.

Mac os x lion 10.7 on mac book pro not updating and running very slow

i am using mac os x lion 10.7
problem it is not updating and running very slow. How to improve?

If you don't already have a current backup, back up all data before doing anything else. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve your problem. The backup is necessary on principle, not because of anything suggested in this comment. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The procedure will help to identify which such modifications you've installed, as well as some other aspects of the state of the system that may be pertinent.
Don’t be alarmed by the seeming complexity of these instructions — they’re easy to carry out. Here's a brief summary: You copy a line of text from this web page into a window in another application. You wait about a minute. Then you paste some other text, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, paste again. That's all there is to it. Details follow.
You may have started the computer in "safe" mode. Preferably, these steps should be taken while booted in “normal” mode. If the system is now running in safe mode and is bootable in normal mode, reboot as usual. If it only boots in safe mode, proceed anyway.
Below are instructions to run a UNIX shell script. It does nothing but produce human-readable output. However, you need to be cautious about running any program at the behest of a stranger on a public message board. If you question the safety of the procedure suggested here — which you should — search this site for other discussions in which it’s been followed without any report of ill effects. If you can't satisfy yourself that these instructions are safe, don't follow them.
The script will line-wrap or scroll in your browser, but it's really a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it.
If you have more than one user, and the affected user is not an administrator, then please run the script twice: once while logged in as the affected user, and once as an administrator. The results may be different. The administrator is the user that is created automatically on a new computer when you start it for the first time. If you can't log in as an administrator, just run the script as the affected user. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign ($) or a percent sign (%). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.

Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter your password, the script will run anyway, but it will produce less information. In most cases, the difference is not important, so don't worry about it.
The script may take up to a few minutes to run, depending on how many files you have and the speed of the computer. Wait for the line "[Process completed]" to appear in the Terminal window.
You can then quit Terminal. The output of the script will have been copied to the Clipboard automatically. All you have to do is paste into a reply to this message by pressing command-V again.
Please note:
☞ This procedure is all copy-and-paste — type nothing in the Terminal window except your login password if and when prompted.
☞ Remember to post the output. It's already in the Clipboard when you see "[Process completed]" in the Terminal window. You don't have to copy the output; just paste into your web browser.
☞ If any personal information, such as your name or email address, appears in the output, anonymize it before posting. Usually that won't be necessary.

Healing brush/Clone stamp tool and others very slow processing

Healing brush/Clone stamp tool and others very slow processing. System resources monitor shows only 700MB (of 5GB allocated to Photoshop) RAM and 30% CPU is used to perform such tasks as healing brush. Process bar comes up and is painfully slow to complete the task. I don’t understand why does Photoshop not use all the resources available/allocated? No other programs are running at the time, I have tried all the suggestions on this forum and all over the Google. My brand new system is: Intel I7 4770K overclocked to 4.3GHz, 8GB 1600 RAM, Samsung PRO 120GB SSD system drive, 100GB scratch disk. The photos I usually work on don’t exceed 20MB in size. Any suggestion would be appreciated. Thanks

Thanks for the answer.
I have not mentioned the GPU because the processes I described (as far as I know) are not supposed to be using GPU resources. So far I have not been able to afford the GPU i want which is GTX770, so I use Intel 4600 built in graphics instead. To be honest I find, that 4600 graphics is quite powerful. I am able to play Mass Effect 3 on Full spec on max res without game slowing down. And Windows 7 64bit index score is 7.8 for the 4600 graphics. Overall index score is 7.8 on my PC righ now.
I'll try to get the Photoshop system info as soon as possible.
Thanks again.

firefox maxing my cpu and runs VERY slow i have reset firefox and re installed it, diddnt work i have googles searched about it and tryed so manny things to fix it but nothing works this is my last idea posting here

Did you do a clean reinstall and deleted the Firefox program folder?
*(32 bit Windows) C:\Program Files\Mozilla Firefox\
*(64 bit Windows) C:\Program Files (x86)\Mozilla Firefox\
Try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.
Create a new profile as a test to check if your current profile is causing the problems.
See "Creating a profile":

*http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues
If the new profile works then you can transfer some files from an existing profile to the new profile, but be careful not to copy corrupted files.

I'm having the same problem (iTunes 11.02!) .
I think this one isn't resolved because it IS rare: I've had iTunes on about 7 different machines (Mac and PC) since it begain (2001). In fact I maintain the same library without issues for over 10 years. Anyway this is the first time it's occurred (in my case it's happened on a pretty recent Mac Laptop). But as you may have discovered, google/bing searches for similar problems yeild VERY few results.
A guy at the Apple store was able to temporarily fix by doing some low level cache removal, that may give a glimpse to the reason, but is not a permanent fix.
I'm going to try a few things will report back if I have any luck**.
***If anyone else want to give it a try: Before starting bookmark the following: http://support.apple.com/kb/HT1391 this describes the location and purpose of most of the iTunes library files. And, any apple support docs on creating a new iTunes library... I'm unwilling to try the let iTunes "Keep iTunes Media folder organized " cause I have my own organization method.

Here is the details of my problem:
I have oracle 11g installed on machine1 (ubuntu 64bit) , and I have MonetDB installed on machine2 (ubuntu 64bit, ip= 192.168.56.101)
I need to access MonetDB database from oracle.
I followed the configurations steps but I get always the following error:
select "id" from "test"@monetdb;
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[unixODBC][MonetDB][ODBC Driver 11.11.11]Client unable to establish connection
{08001}
ORA-02063: preceding 2 lines from MONETDB
I installed unixODBC on the machine1 and I used MonetDB ODBC driver which generates the following odbc.ini file
[monetdb]
Description = MonetDB
Driver = /usr/lib64/libMonetODBC.so
Host = 192.168.56.101
Port = 50000

Here are my configurations:

Hi,
Firstly, try to configure your gateway listener on another port than 1521 as it is the default one for database. Don't forget to change also the port in TNSNAMES.ORA.
Then use the host machine or ip address rather than the local host in the LISTENER.ORA and TNSNAMES.ORA.
Avoid to use $ORACLE_HOME in the ENVS from LISTENER.ORA but use a complete PATH.
Then test your ODBC connection outside Oracle. What is the result?
Try to get result of the following commands on the Oracle machine1 :
$cd /usr/bin
$./odbcinst -q -d
$./odbcints -q -s
Change parameter in gateway init file:
HS_FDS_TRACE_LEVEL=DEBUG
Execute your SELECT statement:
select "id" from "test"@monetdb;
Get the gateway trace file in /u01/app/oracle/product/11.2.0/dbhome_1/hs/log and send us
Thanks

Migrate From MS Access 2003 to Oracle using Oracle SQL Developer 3.0

Hello All,
I am trying to migrate Access DB .mdb using the Oracle SQL Dev 3.0 Data Migration Wizard, everything go very nice and smooth until the Capture Step, for sure am using the online mode, in the Capture Step the list of available databases is empty and a Msg Box saying that the DB list should have at leats one database selected, so I don't know what's that mean or how to fix this.
in my .mdb file I have four tables and I can copy the data to Oracle using the Right click and copy to Oracle Function, but it really takes much time.
Any help would be really appreciated and thanks in advance.
yours,
Hussein

Just to clarify:
You have created the migration repository and start the migration using Tools => Migration => Migrate
- now you've selected the repositiry
- specified a project
- selected the source database
=> you've choosen the ONLINE Mode
==>> and now you don't see your MS Access database in the "Connection" List
Is this correct?
If the steps you're doing match the steps I've posted above, then please be aware for MS Access migrations you need to choose the OFFLINE method. The MS Access source database information is collected by the MS Access Exporter available from Tools => Migration => MS Access Exporter
Once you've created the XML/OCP file you specify this newly created file during the OFFLINE migration mode.
If your steps differ from mine, please post yours more detailed.
Thx.

Problem copying data from postgres to Oracle via dg4odbc

Hi All,
I am trying to migrate data from a postgres moodle database to an oracle one. I have set up dg4odbc and it is mainly working, except when I try to insert select for some tables only.
Eg.

Migrate from Access 97 to Oracle using Migration Work Bench to mi

When I try to use Migration work bench to migrate an Access 97 database to Oracle using OWB I get "failed to truncate Source Model ORA-00942 tables or view does not exist" error message and I could not go further.
This happens during clearing the Source Model. Doe any one know what is this error means or any one had this problem before.
Thanks
Myl

Hi Njha,
Did you create the Source Model using OMWB and then delete the tables in the OMWB repository manually ? Or is there a chance that the tables in your repository could have been corrupted in some way ? The OMWB is simply trying to truncate the tables it filled when a previous attempt was made to capture the source model before it re-populates the tables with data from your subsequent attempt at a capture. If the tables it is trying to truncate have been deleted or are corrupt, this error will be displayed.
A workaround to your problem would be to drop the schema you are using for the OMWB repository and create a new one.
I hope this helps,
Tom.

How to access MYSQL from Oracle 10g and vice versa

I will like to know how do I create a database link between Oracle 10g and MYSQL database on windows. I have been saddled with responsibility of ensuring the communications between the 2 databases and I have searched everywhere on google, I could not find anywhere where this is explain explicitly and made work.
THank you

In general Oracle offers 2 different products to connect from an Oracle database to a MS SQL Server. The first product is for free and it is called
As DG4ODBC is a generic connectivity based on ODBC it allows you to connect to many foreign databases as long as you have a suitable ODBC driver.It for example allows you to read from text files but also connect to foreign databases like MS SQL Server or IBM DB2. Due to this wide variety of foreign data sources tha capabilities of DG4ODBC are very limited. It only supports a few Oracle functions that it can directly map to foreign database equivalents. All other functions will be post processed. Post processing means that ALL records from the foreign table(s) will be fetched into the Oracle database and the result is then processed locally - so depending on the amount of data stored in the foreign database it might take a while.
To be complete here some notes to follow up:
This Oracle support note describes possible options you have to connect to a foreign database:
Document 233876.1 Options for Connecting to Foreign Data Stores and Non-Oracle Databases - For example - DB2, SQL*Server, Sybase, Informix, Teradata, MySQL
So you see, to connect from Oracle to MySQL you need to use the Database gateway for ODBC release 11.2 (HSODBC which was shipped with 10g was desupported in march 2008).
The Database Gateway for ODBC 11.2 (=DG4ODBC) license is included in the Oracle database license and it allows you to connect with a suitable 3rd party ODBC driver to a foreign database.
For your MySQL connection you only need to download and configure the MySQL ODBC driver from the MySQL web site. Once you can connect with the ODBC driver you could then download and configure DG4ODBC.
As you didn't post on which platform your Oracle database is installed, here 2 notes for common platforms:
How to Configure DG4ODBC on 64bit Unix OS (Linux, Solaris, AIX, HP-UX Itanium) to Connect to Non-Oracle (Doc ID 561033.1)
How to Configure DG4ODBC (Oracle Database Gateway for ODBC) on 64bit Windows Operating Systems to Connect to Non-Oracle Databases Post Install (Doc ID 1266572.1)
- Klaus

Accessing Postgres from Oracle using DG4ODBC and psqlodbc very slow
