Prevent remote database access

we cannot change easily our passwords and we must prevent remote access to SYS and SYSTEM accounts.
Is there a way to prevent remote database access on SYSTEM account without changing password ?

Hi,
Look for this tip in http://www.oracle.com/technology/oramag/code/tips2004/061404.html
I hope this helps

Remote database access via JDBC?

Hello,
Can anyone give me info on accessing remote databases (i.e. Microsoft
Access, etc) from Java programs (Servlets, JSP's, Classes) residing on the
iSeries (AS400) or perhaps any platform?
I currently have a couple of web applications set up on the Websphere App server that access DB2/400 database and I also have some Java Classes on PC's that access MS Access datafiles. I would like to begin writing the majority of my applications that run on the iSeries (or host system) that can remotely access other databases on our network.
Any info would be of great help to me.
Thank you
Don

I don't know of any existing Access JDBC drivers that support remote access, after all, the Access database itself is not remote access capable except via file sharing. One possibility is to look for a Type 3 JDBC driver that supports reuse of other Type 1 (ODBC bridge), Type 2 (Java/Native Mix) and Type 4 (pure Java)JDBC drivers on the server side.
If you were using WebLogic Server, I suppose you could use its remote JDBC facilities, but that won't help you.
One problem you will have to face is that Access JDBC drivers are not (if I recall) meant to be used in a multithreaded fashion. Good luck. By the way, it might be far simpler to port the Access database to DB2/400.

Publishing reports to Enterprise - Remote database access.

Enterprise newbie.
I can publish a report that accesses a database residing on the same server as Crystal Enterprise. Under the CMC, report process, database, I'm using the default report DB connections option. It runs fine in the user mode.
The Problem
Attempting to publish a report accessing a database not located on the same server as Crystal Enterprise, I get theis error: " There was an error retrieving data from the server: The database logon information for this report is either incomplete or incorrect. "
I've tried a number of variations on the process database setup and have established user accouts on the remote server, using that accout as the report user and pw under process - database.
Both reports created on my desktop with ODBC conections.
I think I am missing some page or cache server set-up. Any suggestions appriciated.
Paul

Hi,
If the ODBC connection is set up properly then make sure the servers in the CCM are running on the domain administrator account.
Please revert in case of any queries

Remote database access (db2)

How can i connect database remotely?
i can connect it locally but first time trying remotely

You probably are looking for a class 3 driver for DB2.
Check which driver you are using and set it right and correct the URL to also include the hostname for the remote DB2 instance.

PhpMyAdmin remote database access?

Hi
Our professor provided us a url to put our database there. netcentric.dlsu.edu.ph:8100/pma
The problem is, I can't access it through jdbc. My connection statement is this.
final String URL = "jdbc:mysql://netcentric.dlsu.edu.pht:8100/pma/webdeve2";
Connection conn = DriverManager.getConnection(URL, user, pass);
What should my url be? Thanks

The statement above certainly looked like a java and jdbc question.
>
final String URL = "jdbc:mysql://netcentric.dlsu.edu.pht:8100/pma/webdeve2";That looks like jdbc as well.
php on the other hand would look something like the following.
mysql_connect($dbhost, $dbuser, $dbpass)
So how did the question become solely about php?

Disabling remote database access encryption

We've setup an Oracle 9i enterprise db and client on two separate Linux machines in a lab environment. Applying sniffer to the network we see that the client attempts a non-encrypted connection but the db rejects the request and continues with the connection.
Is there any way to disable encryption? Our ultimate goal is to view the contents of SQL/TNS packets for development purposes.
Thanks in advance,
Chris

Thanks for the above pointer! So with the client initiating with 'accepted' and the server returning 'rejected' Table 2-1 describes OAS as being off by default.
The results of a sql log trace are the same as sniffer with samples of the payload below. Is this considered cleartext?
Thanks for all your help.

Problem while accessing object in remote database

Hi All,
We have a procedure "UPDATE_CONV_DETAILS" created in the remote databse in the "apps" schema. The synonym for the procedure is created in the billing schema(present in the remote database). A dblink is created the local database through which we are tring to access the remote object "UPDATE_CONV_DETAILS".
Dblink script:
create public database link PRE_TO_CEL
connect to BILLING
identified by BILLING
using 'MAP1';
When trying to access the object from the local machine using the schema name.object_name it works fine:
SQL> DESC APPS.UPDATE_CONV_DETAILS@PRE_TO_CEL
PROCEDURE APPS.UPDATE_CONV_DETAILS@PRE_TO_CEL
Argument Name Type In/Out Default?
IN_MOBILE VARCHAR2 IN
IN_SERVICE_CODE VARCHAR2 IN
IN_STATUS VARCHAR2 IN
OUT_ERROR_CODE NUMBER OUT
But when trying the access the same object using the synonym_name it gives the error:
SQL> DESC UPDATE_CONV_DETAILS@PRE_TO_CEL
ERROR:
ORA-04043: object APPS.UPDATE_CONV_DETAILS does not exist
Regards,
Kirti

You have two schema.
apps
billing
both reside in remote database.
there on procedure and on procedure u create one synonym and u want to access it.
ur remote database name is "map1"
on ur local database ur create one dblink to access remote database.
ORA-04043: object string does not exist
Cause: An object name was specified that was not recognized by the system. There are several possible causes:
- An invalid name for a table, view, sequence, procedure, function, package, or package body was entered. Since the system could not recognize the invalid name, it responded with the message that the named object does not exist.
- An attempt was made to rename an index or a cluster, or some other object that cannot be renamed.
Action: Check the spelling of the named object and rerun the code. (Valid names of tables, views, functions, etc. can be listed by querying the data dictionary.)

ORA-28150 when accessing data from a remote database

Portal Version: Portal 3.0.9.8.0
RDBMS Version: 8.1.6.3.0
OS/Vers. Where Portal is Installed:: Solaris 2.6
Error Number(s):: ORA-28150
I have a problem with using a database link to access a table in
a remote database. So long as the dblink uses explicit logins
then everything works correctly. When the dblink does not have a
username then I get the ORA-28150 message. The database link is
always public. A synonym is created locally that points to a
synonym in the remote database. I am using the same Oracle user
in both databases. The Oracle portal lightweight user has this
same Oracle user as its default schema. The contents of the
remote table are always visible to sqlplus, both when the link
has a username and when it doesn't have a username.
All the databases involved are on the same version of Oracle.
I'm not sure which Oracle login is being used to access the
remote database, if my lightweight user has a database schema
of 'xyz' then does portal use 'xyz' to access the remote
database? I would be very grateful for any help or pointers that
might help to solve this problem.
James
To further clarify this, both my local and remote databases
schemas are owned by the same login.
The remote table has a public synonym.
The link is public but uses default rather than explicit logins.
The local table has a public synonym that points to the remote
synonym via the database link.
If I change the link to have an explicit login then everything
works correctly.
I can view the data in the remote database with TOAD and with
sqlplus even when the database link has default login rather
than explicit login.
This seems to point to Portal as being the culprit. Can anyone
tell me whether default logins can be used across database links
with portal?
TIA
James

One way to do this is by creating a database link and joining the two tables directly. But this option is ruled out. So please suggest me some way of doing this.Thus you MUST use two connection strings.
Thus you are going to be either constructing some intricate SQL dynamically or you are going to be dragging a lot of data over the wire and doing an in memory search.
Although realistically that is what the database link table would have done as well.
Might be better to look at moving the table data from one database to the other. Depends on size of course.

Connect to a remote MS Access database using RmiJdbc

Hello,
I want to access a remote MS Access database from oracle stored procedures.
Does anyone know how i can load the RmiJdbc driver using the loadjava command or with any other way.
Because when i try to load RmiJdbc.zip using the loadjava command I am getting the error:
ORA-29533:attempt to overwrite class or resource string while defining or compiling scott.TestClient
this error is occured for multiple files...
I don't know how to delete this classes.
Because this error occured and the first time i tried to load Rmijdbc driver.
and when i use the dropjava command to drop it,and then load it again the same error occures.
Can anyone help me how to load this driver?
Please answer because i need it as soon as possible.

The document is in different database and used by other schemas as well from that database.
.Net is GUI.Daniel raised a very important point. Moving that document via another database doubles the network load for that operation. And doubles the performance impact on the client.
Is this in any way a sensible thing to do? Most definitely not.
Assuming that the client cannot reach the remote database containing the documents, and that can only be done via the local database, then you need to look at options such as materialised views. Replicate the remote content from the remote database to the local database at regular intervals.
As the data set is large (containing LOB documents), consider fast incremental refreshing (and not pull the entire data set across with each refresh).
Yes, you can write PL/SQL code that grabs the remote document and copies it into a local LOB and then dish that up to the client. But the impact of this on the network and performance are major concerns that need to be thoroughly evaluated first.

PERFORMANCE while accessing remote database DB2 on AS/400 using WAS

Subject: PERFORMANCE while accessing remote database
We have IBMWebSphere Application Server Standard Edition 3.5.3 running on
AS/400 iSeries Server (V4R5, test)and local DB2 Database.
I am using AS/400 Developer Kit for Java JDBC Driver(type2, com.ibm.db2.jdbc.app.DB2Driver)
to talk to local database. The performance was very good.
When I try to access remote database (every thing same as local) which is on another AS/400
machine of V4R4 (we use it for production, remote database) using IBM Toolbox for Java JDBC driver
(com.ibm.as400.access.AS400JDBCDriver, type 4 driver), I can see 30to40%decrease in performance.
Here we have WAS on previous V4R5 AS/400 machine.
My questions are
Is the performance decrease is due to
1. the driver I am using? if it is Is there any other alternative drivers to access
remote database to boost performance?
2. the release difference of local(V4R5) and remote data base(V4R5)
3. Currently most uses remote database while we do this testing. Is that the cause?
or Is there any other cause or Drivers etc??? Suggestions and help is most welcome.
Thank you.

What about
4. the data has to travel across the network.

How to access remote database using applet

hi all,
I want to know how to access remote database using applet,
Please help me anybody.
Regards
Jesu

If the database is on a public server, you probably can't access it directly (security wise). You can make your applet talk to a server-side application, which makes the database calls on behalf of the applet. But even in an intranet environment this setup is often preferable, because you don't need to distribute a JDBC driver to all your clients.

WebSphere V5 accessing remote database

Sorry to post IBM product specifice question here. I didn't know where else to put it.
I need to deploy J2EE appl using CMP beans to WebSphere Application Server version5 to use remote database(DB2) within LAN.
I have no idea to where to begin and what to look for.
Can anyone guide me here?

You need to configure that database as a data source in Websphere using the admin tool. Check the help for details.

How prevent REMOTE LISTENER register on SCAN LISTENER

Hi All,
Oracle Database 11.2.0.3
How prevent remote registration on SCAN Listener?
I need to know if there is a way of prevent one instance register on listener using remote_listener parameter without affect incoming connection of client.
These parameter below is not enough to meet my tests:
tcp.validnode_checking = YES
tcp.excluded_nodes = {list of IP addresses}
tcp.invited_nodes = {list of IP addresses}The tcp.excluded_nodes and tcp.invited_nodes parameters deny and enable specific client IP addresses from making connections to the Oracle listener.
Levi Pereira

Yes, I posted about that 4 days ago:
Re: Local Listener Validity in 11gR2
I have not yet had an opportunity test it, have you successfully tested the procedures? Basically it forces all registration event to occur over IPC/TCPS. I have seen the original test case for this, and while yes, it is true that you can connect if this is not in place, it is a very complex man-in-the-middle vulnerability requiring access to your [hopefully firewalled] database server.

Dw cs5 with existing wordpress site hosted on yahoo need help connecting to existing remote database

I am having trouble establishing a database connection. I can connect with test databases but am having trouble using dreamweaver wtih my existing wordpress website. Am I able to use dreamweaver to edit and live view my changes before uploading the changed files to my live site? Am I able to access my existing wordpress database with dreaweaver? I have imported it to my testing server/database but still seem to be having trouble establishing a connection with it (think maybe my folder hierarchy might be off).
macintosh HD/Applications/MAMP/htdocs/nwm/wp/index.php
"nwm" is the name of the folder that I have copied all of my site files to and the folder I have dreamweaver pointing to. "wp" is what I have all of the wordpress files in (the ones I copied from my yahoo server - including all my current theme files etc.)
I am trying to put the info into the mysql connection dialog box:
Connection Name: Testing (i am assuming this name is for my benefit only and doesn't actually matter)
MySQL Server: mysql
User Name: *****
Password: *****
Database: wp
and am getting this message
MySQL Error#: 2013
Lost connection to MySQL server at 'reading initial communication packet', system error 61
did some google seaches of the error. Tried turning off the firewall, and the advance tab allow mysql incoming (there were 2 one was allow one was not allow. I changed both to allow)
Cant really find anything on yahoo to help me out. Looked in phpmyadmin database named wp: wp_users to get the username and password (which due to previous look for help - I think the password was encrypted cuz it looked like a bunch of mumbo jumbo and am fairly certain I know the correct password).
Any help would be greatly appreciated!! I spent $50 on live chat last night trying to resolve the issue only to find out at the end that the guy really didn't understand my problem and doesn't have dreamweaver. I have also watched countless videos on Lynda.com and have been thru forum after forum. While this problem is only a couple weeks old since I just got CS5. I have been having trouble making any headway learning php since I cant seem to make it past the set up parts. I have done the php / mysql essential training on lynda.com with relative success except that I really dont want to work with any more exercise files so I didn't go on to the beyond the basics. I recently went thru most of the Dreamweaver CS5 and Wordpress 3. Also did the first 4 chapters of Dreamweaver CS5 with PHP and MySQL. I need to start integrating things into my live sites. I am also trying to work my way thru the learning php, mysql, javascript book by o'reily media by robin nixon (as fun as reading a math text book) can't get thru it since I can't relate any of it to my current sites/needs
I am on MacBookPro OSX 10.6.6
Installed MAMP to specification on all 20 tutorials I have tried including lynda.com
Tested the testing server and is working
Just installed dreamweaver cs5
have been using wordpress online to create and edit posts (recently upgraded to 3.? whatever the latest update was online which I believe update the files on my yahoo server?)
Have also installed wordpress on my computer (several times thru each tutorial trying to get this right.)
Am I expecting the impossible?

If wordpress controls it's own connection why am I unable to use the live view. I have synced the remote site to my local computer so all the files should be just as they are online with the exception of the DB which contains most of the content.
I have done all of those steps. I have even exported the database from inside internet phpmyadmin and imported into computer phpmyadmin. When I hit live view I get one of couple of errors.
1. "One is that the dynamic related files could not be displayed due to an internal server error"
At some point I was able to view some sample files inside dreamweaver. But I would like to be able to view my real site files. I was able to "connect" to the local databases (not the copy of my real one - I think that maybe that was because it is somehow nested inside another db an am going try to reimport to new location). And then I changed the host/username/password trying to deal with the internal server error. Now instead I get the cannot connect to the database Error 2016 or whatever from the origianl post. Also, I am using yahoo if that matters and all I can find about what their server name is: mysql - is that correct?
I have been thru this so many times with so many different tutorials I am losing track of what is what.
2. Can I access my remote database within dreamweaver? I do not want to create dummy files (seems to be a waste of time). And while if it had worked exporting/importing a duplicate on to my computer would have satisfied me for a little while it also seems some what counter productive. Since every post and page is different if I were doing a daily updates etc how would I be able to change the formating or design of them if I can't access the remote files. Would I re- import everytime I want to work on it to get current database?
I am trying to be clear. I listed all the specs I could think as listed in your "how to get help fast post" (yes I read that at least twice too) of all of the steps and possible reasons for my problems. I also thought that the forum was on a seperate site so I didn't think it would count as a duplicate. I am frustrated to tears and am feeling incredibly stupid that after all this time and all these tutorials yes you are right I obviously am not understanding what is going on which is why I am on this forum.
