RE: Cold Fusion and Bind Variables
Hi Jared, Look at QFQUERYPARM: Usage The CFQUERYPARAM is designed to do the following things: Allows the use of SQL bind parameters. Allows long text fields to be updated from an SQL statement. Improves performance. The ColdFusion ODBC, DB2, Informix, Oracle 7 and Oracle 8 driverssupport SQL bind parameters. However, at present, the ColdFusion Sybase 11 driver and Sybase native driver do not support SQL bind parameters. If a database does not support bind parameters, ColdFusion still performs validation and substitutes the validated parameter value back into the string. If validation fails, an error message is returned.

He develops primarily in Cold Fusion, which I know little about. I'm trying to teach him the difference between literal and bind variables, and the importance of knowing the difference. While it is easy to demonstrate this in PL/SQL or Perl, I have no idea how to do so in CF. A few minutes of googling didn't really turn up anything useful. I'm looking for some examples of using bind variables in SQL as used in Cold Fusion that connects to Oracle 8i. If you have one, the virtual beer is on me. :) Jared
rogue SYS connections
Solaris 2.8 Oracle 8.1.7.0. We have session auditing enabled, and see rogue connections as SYS from several remote databases. The os_user of the remote system is always oracle and there are several different remote hosts involved. I can't figure out how they are gaining access this way. Our SYS password is set to a random string, not the default, and we change it frequently. There are no corresponding telnet sessions indicating access is local from our server, and we also change our oracle password frequently.

RE: rogue SYS connections
Thanks Ron. No, we use SQL-Backtrack instead of RMAN. However SQL-Backtrack does show a diff flavor of rogue connections of ###NOBODY. The remote database systems that are connecting to our database as SYS are not ones we support. What is common about these databases is they do have logins to our database. Those logins have only 'create session' privileges with select grants on views we created for our application.

Veritas disk groups
A very long time ago, there was a whitepaper on implementing Veritas for Oracle systems. I think it was published by Veritas. I've googled and searched veritas.com and can't find it anywhere. IIRC, one of the recommendations in the whitepaper was to not use rootdg for database files, instead create a separate disk group. Does anyone have a link to some documentation or best practices?Our sys-admin insists on creating filesystems for Oracle on rootdg, but I seem to recall there are some risks in doing this. Maybe I'm hallucinating.

RE: download metalink articles - save target as
MS Outlook a.k.a Outhouse Mail. -Original Message- Sent: Monday, September 22, 2003 1:55 PM To: Multiple recipients of list ORACLE-L Paula, I think the problem may lie in MetaLink's use of the icky icky frame construct (See http://www.useit.com/ for explanation of why frames are bad and aren't even needed). You don't say what browser you're using, but I can guess. Toss out that virus-toting piece of dung, IEeee. Actually, keep it on your system, but make sure you have Work Offline checked before closing it for the last time. That way, your MS Outlook (Lookout!) mail won't be able to automatically retrieve junk off of the web when you preview or read messages. This will help keep your spam count low. So, in Mozilla (or other Gecko variant like Firebird or perhaps even Netscape) or Opera 7.2.0, right click on the link to the article you want. In the popup menu that appears, choose Open link in another tab or Open link in another window or whatever option you have. With the link in it's own space, you should be able to figure out how to save the article locally. One thing to watch for when using this technique is that the MetaLink pages are often coded to open new links in a frame ([EMAIL PROTECTED]@#% frames!) from your original MetaLink window/tab, unless you right-click every link into a new window/tab. Mozilla and it's variants also offer a middle-click to automagically pop the link into a new window/tab. These other browsers have the nice intended effect of being available on multiple platforms, so you have the ability to call up MetaLink without needing an MS Windohs box. :) HTH! GL!

ref_cursor's
I've RTFM'd looking for advantages/disadvantages of ref_cursors vs. out parameters. We have a developer who insists on using out parameters instead of ref_cursors. He hasn't coded PL/SQL since Oracle7. The application program that calls the PL/SQL package is written in C#. I'm at a loss for words. I'm not a PL/SQL expert, but it seems that ref_cursors have the advantage of not needing to define PL/SQL variables, and that it's easier to pass a result set back to the calling program. I also assume that ref_cursors have better performance. Can someone clarify this? Maybe I'm confused.

I may have the wrong list as its a Java related question. If so could someone please direct me to the correct list. I'm trying to write a large file into a BLOB column of an Oracle 9I DB, using a set of classes as follows .. I'm creating a general java.sql.Connection as follows ... dbUrl = "jdbc:" + dbProtocol + ":thin:@" + dbHost + ":" +dbPort + ":" + dbName; Class.forName(oracle.jdbc.driver.OracleDriver); return DriverManager.getConnection(dbUrl, dbUser, dbPass); So I'm returning from here with a normal java.sql.Connection. Then I'm creating a the BLOB as follows ... oracle.sql.BLOB dataFile = new BLOB((OracleConnection) con, dataAsBytes); Note here that I am casting the java.sql.Connection to an OracleConnection and passing this as an argument. Why does the connection need to be passed as an argument here ?? I am then using a PreparedStatement to send the BLOB to the DB. stmt.setBlob(1,dataFile); stmt.setString(2,time.toString()); stmt.setLong(3,time.getTimeInMillis()); stmt.executeUpdate(); stmt.close(); con.close(); My problem is that I keep getting the following exception java.sql.SQLException: ORA-24813: cannot send or receive an unsupported LOB at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:134) at oracle.jdbc.ttc7.TTIoer.processError(TTIoer.java:289) at oracle.jdbc.ttc7.Oall7.receive(Oall7.java:579) at oracle.jdbc.ttc7.TTC7Protocol.doOall7(TTC7Protocol.java:1894) at oracle.jdbc.ttc7.TTC7Protocol.parseExecuteFetch(TTC7Protocol.java:1094) at oracle.jdbc.driver.OracleStatement.executeNonQuery(OracleStatement.java:2132) at oracle.jdbc.driver.OracleStatement.doExecuteOther(OracleStatement.java:2015) at oracle.jdbc.driver.OracleStatement.doExecuteWithTimeout(OracleStatement.java:2877) at oracle.jdbc.driver.OraclePreparedStatement.executeUpdate(OraclePreparedStatement.java:608) at com.changingworlds.nav.updatemanager.database.DatabaseManager.addToHistoryDB(DatabaseManager.java:138) I've been looking all over for a solution to this exception andI'm finding that itsusually caused when I am using thedifferent versions of oracle on server and client.
