Question about secuting connection to the database

Hi.
I need to fix an Oracle Consulting custom solution that became incompatible with the new version of the application.
What's the catch:
this solution is basically a SQL*Plus script that resides on the filesystem and performs a bunch of commands to generate and load data from Views.
My difficulty with this is that one of those commands is a CONNECT.
I'm concerned about the security implications of performing an "open connect" via SQL*Plus command like this.
My questions are:
1) Is there a way to secure the SQL*Plus session so that its commands are not visible via a Trace or something else?
2) What's the best way for me to perform that CONNECT command in a secure way, so that the user and password do not become visible?
Thank you.

I do not see the problem.. SQL*Plus is a client like any other client. VB. Java. Delphi.
Such clients will also make use of a connect string to Oracle. In some cases they will prompt for username and password from the end-user - assuming Oracle schema authentication is used. In many cases they will automatically (via an internal hardcoded connect string) connect to an app schema and then use a USERS table to authenticate the end-user (and thus not use Oracle security).
The biggest concern in this case is making this connect string visible. EXEs and DDLs can be dumped and ASCII strings extracted - and with it, potentially hardcoded username and passwords.
In case of a SQL*PLus script, this is in clear text in the actual script itself. But unlike a VB EXE that runs in the wild (on some client PC somewhere), I would assume that in your case this maintenance process runs from a secure o/s account on a server.
In that case, all that is needed to revoke read/write access to that script from all other o/s users on that server.
Of course, this assumes that the actual SQL*Plus script uses the CONNECT command and not the sqlplus command line - as command line switches are visible via process monitors.
Another option is not to use Oracle schema authentication for that maintenance process, but o/s authentication. In which case only that o/s user can logon to that schema and execute code. Thus no username and password to protect as the o/s account itself provides the protection.

Connection to the database (beginner's question)

I do not quite understand the relation between "@connect alias" and actual TNS name. The documentation tells that the syntax should be:
connect user/pass[@connect_alias] as sysdba
I have TNS names defined myora01 and global one myora01.home.net. Are one these two names suppose to be a "@connect_alias"? Well, it does not work this way:
connect user/pass@myora01 as sysdba;
ERROR:
ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
Where is my mistake?

LeonidIf you use the syntax "sqlplus scott/tiger" (or within sqlplus, "conn scott/tiger"), you are asking to connect to a local (on the same machine) database instance identified by the value of the environment variable ORACLE_SID. Tnsnames.ora is not involved.
If you use the syntax "sqlplus scott/tiger@mydb" (or within sqlplus "conn scott/tiger@mydb") you are asking to connect to the database (local or remote) identified by the "mydb' entry in your tnsnames.ora file.
=================================
Assume you have the following in your tnsnames.ora:
{code}
larry =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = myhost)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = curley)
{code}
Now, when you issue a connect, say like this:
{code}
$> sqlplus scott/tiger@larry
{code}
tns will look in your tnsnames.ora for an entry called 'larry'. Next, tns sends a request to (PORT = 1521) on (HOST = myhost) using (PROTOCOL = TCP), asking for a connection to (SERVICE_NAME = curley).
Where is (HOST = myhost) on the network? When the request gets passed from tns to the next layer in the network stack, the name 'myhost' will get resolved to an IP address, either via a local 'hosts' file, via DNS, or possibly other less used mechanisms. You can also hard-code the ip address (HOST = 123.456.789.101) in the tnsnames.ora.
Next, the request arrives at port 1521 on myhost. Hopefully, there is a listener on myhost configured to listen on port 1521, and that listener knows about SERVICE_NAME = curley. If so, you'll be connected.
A couple of important points.
First, the listener is a +server side only+ process. It's entire purpose in life is the receive requests for connections to databases and set up those connections. Once the connection is established, the listener is out of the picture. It +creates+ the connection. It doesn't +sustain+ the connection. One listener, running from one oracle home, listening on a single port, will serve multiple database instances of multiple versions running from multiple homes. It is an unnecessary complexity to try to have multiple listeners. That would be like the telephone company building a separate switchboard for each customer.
Second, the tnsnames.ora file is a +client side+ issue. It's purpose is for addressess resolution - the tns equivelent of the 'hosts' file further down the network stack. The only reason it exists on a host machine is because that machine can also run client processes.
What can go wrong?
First, there may not be an entry for 'larry' in your tnsnames. In that case you get "ORA-12154: TNS:could not resolve the connect identifier specified" No need to go looking for a problem on the host, with the listener, etc. If you can't place a telephone call because you don't know the number (can't find your telephone directory (tnsnames.ora) or can't find the party you are looking for listed in it (no entry for larry)) you don't look for problems at the telephone switchboard.
Maybe the entry for larry was found, but myhost couldn't be resolved to an IP address (say there was no entry for myhost in the local hosts file). This will result in "ORA-12545: Connect failed because target host or object does not exist"
Maybe there was an entry for myserver in the local hosts file, but it specified a bad IP address. This will result in "ORA-12545: Connect failed because target host or object does not exist"
Maybe the IP was good, but there is no listener running: "ORA-12541: TNS:no listener"
Maybe the IP was good, there is a listener at myhost, but it is listening on a different port. "ORA-12560: TNS:protocol adapter error"
Maybe the IP was good, there is a listener at myhost, it is listening on the specified port, but doesn't know about SERVICE_NAME = curley. "ORA-12514: TNS:listener does not currently know of service requested in connect descriptor"

Unable to connect to the database to product shared services

Hi
I got an error in configuring shared services with the Oracle server database
"" Unable to connect to the database to product shared services ""
I created a database that is working properly when accessed by a client.
I typed everything in config utility, Does we need to take care of any other servies?
I appreciate if any one help with this.

Version: Hyperion System 9 and Oracle 9i

John is of course correct that XP is not a supported environment for Essbase 9.3.x.
Having said that, I have successfully installed Shared Services, Essbase, and EAS on multiple XP laptops. I have done so with 9.2 (painful) and 9.3.1 (just about painless) although always against SQL Server. This is strictly for development/kick the tires work, never as a production environment.
Planning has quite an issue with XP (and Vista) although I have heard that there is a Windows Registry fix for this.
Of course Oracle support is going to gong you if you call up with questions about your laptop -- it isn't supported.
One last thing -- Shared Services and laptop suspends =! stability. For my development purposes, I have backed off Shared Serivces and just go with Essbase as a service with native security and EAS.

Cameron Lackpour
P.S. VMs are probably the way to go if your desktop/laptop has the horsepower to drive a proper OS with the VM overhead. On a 4 gigabyte laptop with a Duo Core (no, not a Mac, I just can't remember what Intel calls it -- the power of marketing) VMServer running Windows Server 2003 and the full stack is pretty slow, but it works.

Did other user have the same problem? yes
Did you connect through WAN or LAN connection? LAN (Intranet)
Can you tell more about you client/database setup?

Problem with EM (Enterprise Manager is not able to connect to the database)

Hi all,
I've Oracle DB 11g Rel.1 installed on Windows XP SP3. The database is up and running i.e. everyone can connect to the DB by using any App tool e.g. SQL*Plus, Forms, or Reports. It means that the listener and the service is running. But the problem is that when I try to start the EM I see some error messages on the webpage.
It says:

My question is if every thing is working fine then what is the problem with the EM? Why it is not connecting to the DB?

Enterprise Manager is not able to connect to the database instance. Open??

Hello there,
After I installed oracle database and tried to start Enterprise Manager, I got the message:
Enterprise Manager is not able to connect to the database instance.
All statuses are OK (green and up) except database instance. It is also green and up but open. (Details: The instance is open.)
Can anyone help me about it?
I use Windows XP x64 with all patches installed. Oracle database R11g x64.
I tried with different database versions and different machines and different OS and loopback adapter and... my EM still want to log in.
I can log in with sqlplus. It accepts any pass for sys (as sysdba). Why?
My log files are available here: http://195.66.185.187/log.zip

You are using a bequeath connection when logging in with SQL*Plus on the server so the password is not validated.
Log in using SQL*Plus this way:
sqlplus /nolog
followed by
conn sys@<service_name> AS SYSDBA
and provide the correct password
My guess it it will fail.
If so then you need to use the correct password and if you don't know what it is set it when logged on as SYS.

How is the best way to connect to the Database ?

I just have a question regarding to the connection to the Oracle DB.
Every time I create a new JSP I am writing java code such as:
Class.forName("oracle.jdbc.driver.OracleDriver").newInstance();
conn = DriverManager.getConnection("jdbc:oracle:thin:@host:1521:DB",
"user",
"pwd");
Is there a way I can reuse the connection that we create on JDeveloper on the tab Connections, under the Database node ?
Because I would like to centralized more the way how I connect to DB.
Thanks!
Giovani

That is a nice solution, but only works if you use embedded OC4J, if not you must define datasources, maybe in standalone OC4J, OAS, JBoss, etc
this is because the embedded OC4J automatically create datasources if it sees database connectiones created through Connections Tab

How can I connect to the database using the Oracle Remote Diagnostic Agent?

Now I try to study RDA on Windows XP platform,when I run 'rda.cmd',there is a question 'Enter password for 'SYSTEM@'',what is the answer?
Because I didn't know how to connect to database,there are many error messages - RDA-00510: SQL execution disabled,What can I do?

Metalink Note:314422.1 to start
It is asking you to tell how to connect to 'the database that you are investigating' over a network. The answer .... the password for the userid called 'system' in the database specified after the @
I am confused ... you do not know how to connect to your database?

Best Practice for closing a blocking connection to the database.

Background:
Using toplink/eclipselink to manage the the connection to the database.
We support 3 databases, Oracle, Mysql, and MSSQL.
We host the an application locally (SAAS) and we also distribute it to our clients so they can run it on premise.
Problem:
From time to time the application will execute a route that query the DB and will take 10+ minutes. When we find these queries we generally fix them, but it takes time to fix the problem and roll new code to production. We have also found that if an end user executes the query to many times they can potentially bring the service down - maxing out the database connection, or putting a huge load on the DB effectively rendering the system to a crawl.
During this time period the IT team need a way to abort a transaction. The current approach, for our SAAS solution, to scan the database find to the long running query and kill it. The application is smart enough to recover and everything seems to work fine. This doesn't always work for our on premise customers - often they don't have a DBA or adequate resources to monitor the system. Therefore, I'm looking for a way to have the application kill/close any query that is lasting longer then X minutes. We currently track the duration of every thread so I can get the time the thread has been actively running.
Stack Trace
Currently we keep track of how long each thread is running waiting for a response from the database such as the stacktrace below, I would like to grab the connection and physically close it. Since we are using a java socket and it's in a blocking state there is no way for us to interrupt the thread. The only option is to wait for it to receive a response from the db - kill the sql process - or to close the java socket.

Question
What is the best way to grab the connection and close it - from another thread?

The reason for changing the namespace is to guarantee that they appear as different versions. The namespace is part of the strong name of the DLL when deployed. Yes they will be deployed to separate servers because a server can only belong
to one farm. But when you are doing a migration it won't be clear that you need to install the 2013 version since the .DLL will report that it exists in the 2010 farm already. It will work without changing the namespace, but it would be best to differentiate
versions at that level to avoid confusion.

How to create a link to a web page that is connected to the database?

i am developing a web form in java using Oracle's JDeveloper. i created the form which is connected to the database and now i want to put a link in a page that when clicked it shows the form and populates it if necessary. i have no idea how to do that, can anyone please give me an example or where i can find an example?

Its really hard to answer this question with this enough information....Which Jdeveloper version? which technology you are using to create this web form ? ADF BC or others
If 11g then are you aware of Task flows?

URGENT!!!!!!!! Tomcat 5.0 does not connect to the database !!!!!!

We had an already existing system on tomcat 4.1.18. Since migrating to Tomcat 5.0, we are facing lots of problem while trying to connect to the database. The database in SQL Server 2000.
The first time i try to connect (after restarting tomcat service) the system is able to connect to the database but after sometime it again stops connecting.
The beans on our system are able to connect to the database without any problem but when we try using the same via http, it doesnt connect. The classpath is set properly. Also the database drivers are also the latest ones and in the proper place. We have placed them in the common/lib folder. We have checked that normal jsp pages which are not connecting to the database are working fine.
Please HELP!!!!!!!!!!!
Thanks in advance

well.....Tomcat is not a database connecting engines.....U would need to check your db connection codes to check if you have missed anything.....so the first question will be
1. How do u connect to the DB
2. Which type of JDBC drivers are u using.
Finaly, tomcat is not at fault...its the fault of you configuration

How can I speed up the connection to the database?

I am running a JSP application with regular JavaBeans not EJB and connecting to the database through these beans. The connection is set to stay in memory as long as the bean is in session. However when I am running more than 7 sql statements seperatly the execution of the page slows down.
I have tried using connection pooling but doesn't help much.
I am not using the JDBC setting in JRUN, I am connecting through the jdbc.odbc drivers provided by the JDK. Basically coded the connection and the connection pool.
Is there something else that can be done to speed up the execution of the page?
Thanks in advance

Thank you all for your input I was trying to work this project to learn JSP so I am not looking at purchasing any drivers right now. That is the reason why I stuck to the JDBC-ODBC Bridge. Are there any other drivers available for MS SQL Servers that are free.
Jschell,
That suggests you are taxing the system. It could be >connections. It could also be network, cpu, bus, etc. It >could also be memory, if your app starts swapping to >the hard drive it will get substantially slower.How can i figure out which of the above (i.e. memory, cpu, connections, network) are causing the problem.
(Presumably you explicitly close your >ResultSets/Statements/Connections when you are >done with them.)You are right about that yes I am closing them at the end of the session, which I think should be after all of the SQL's get executed but I could be wrong it might be openeing a new connection for each SQL which inturn might be the reason for this whole problem. I will take a look into that.
Thank you all once again.
