RE: jdbc thin client driver
Manas,
Recheck your classpath and the versions of your classes file(i.e. correct
jdk / classes compatibility). This error is clear, it can't find the JDBC
drivers.

I am trying to test a jdbc application using Oracle' thin client driver from
AIX. The database that I am trying to go against is 8.1.6 server on an NT
box. I keep getting the following error on compile:
OracleConn.java:10: Class oracle.jdbc.driver.OracleDriver not found in type
declaration.
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
^
The CLASSPATH does contain classes111.zip. I have also tried using
classes12.zip in the CLASSPATH. Each time I get the same error.
This is the piece of code I'm trying to compile:
public OracleConn()
{ try
{
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
}
catch ( Exception e)
{ System.out.println("Error Loading driver");
e.printStackTrace();
}
}
public Connection getOracleConnection(String dbname, String userid, String
pwd)
{
String url = "jdbc:oracle:[EMAIL PROTECTED]:1521:" + dbname;
Connection myConn = null;
try
{
myConn = DriverManager.getConnection(url, userid, pwd);
System.out.println("Connection successful") ;
}
...
What am I doing wrong
Thanks,
Manas.

Free Java dba monitoring tool and Java source code
Dear List To quote Jared recently 'And if you are wondering 'Should I learn Java?', the answer is 'definitely', as it is capable of many things that PL/SQL is not.' I have to totally agree with him and I think DBA's can enhance their profile by becoming competent in the technology. As part of my masters dissertation I have developed an SQL monitoring tool using Java/JDBC/thin drivers that allows the DBA to see who is taking up the resources currently in a database. The default is physical reads but any statistic can be selected. It displays like Instance manager but gives added functionality that it will extract the SQL that is running currently and allow you to Explain it online. You can sort the session data, kill sessions, etc.. It is a good tool especially if you suddenly get a dip in performance and need to quickly find which process is taking up all the resources. It is also good for ad-hoc monitoring. I know there are better/professional tools out there but not all companies can afford them,this is free and has been built in limited time. I work for an oil company and we have no monitoring tools, we had to rely on our own scripts. Most importantly I will give the source code to all that give me comments on the tool. This is not at all a commercial venture, purely academic. Plus if you want to learn about Java/JDBC this can be an invaluable asset/starting point as you know the subject well and you can see how the tool has been built. The tool is thin client - i.e. no oracle client installation necessary All you need to do is download Java 1.3 from Sun. If you e-mail me offline I will send you my website address where you can download (396kb-takes no time). There is also a link to the sun site for Java 2 download (this takes a little longer as its ABOUT 30MB).But it has all the latest swing classes and is the latest version. As an ex Cobol programmer in the 80's, Java is a wonderfully elegant language to learn and once studied is not as difficult as imagined (I imagined anyway). Sam -Original Message- Sent: Tuesday, March 27, 2001 12:21 AM To: Multiple recipients of list ORACLE-L Oracle has repeatedly stated that PL/SQL is not going away. One good reason for this is that PL/SQL is highly optimized for DML in the database. Java is not, and will not likely ever be as efficient PL/SQL for manipulating large amounts of data. At least IMO. OOP has many benefits, but large scale DML is not one of them, at least not yet. PL/SQL will be around for awhile yet. And if you are wondering 'Should I learn Java?', the answer is 'definitely', as it is capable of many things that PL/SQL is not.

RE: Analyze Question -- How CBO uses column statistics for non-in
They most definitely non indexed will have influence on the CBO - there is the ANALYZE FOR ALL COLUMNS option anyhow, that is there for that reason. I think also likely used in conjunction with histograms on fields - DSS / Data Warehouse : Regards Sam -Original Message- Sent: Saturday, February 03, 2001 6:47 PM To: Multiple recipients of list ORACLE-L non-in Sam, You had the right topic. The original questions was "In what way do statistics (or lack thereof) on non-indexed columns influence the CBO?". I was having trouble thinking of a scenario where this would make a difference, hence my posing the question to the list. I finally thought of a scenario and threw it out to the list. That's the email you responded to. Anyway, I eventually had a chance to test the scenario. Created 2 tables, A and B, each containing 50,000 rows. Each have a indexed column containing consecutive integer values from 1 to 50,000 and a one to one relationship between the tables on this column. Each table also has a second *non-indexed* column. For table A, the second column contains 25,000 distinct values with each individual value occurring 2 times. For table B, the second column contains only 2 distinct values, 0 and 1, with each value occurring 25,000 times. So, I have an index on the tables to support a join between the 2 tables, and, no indexes on the second column in each table. I did a generic analyze compute which would include generating stats on the non-indexed columns. And yes, the CBO would use the stats on the non-indexed column on table A to decide whether to join to table B using an indexed NLJ, or, an FTS and HJ (and in some cases an FTS and SMJ). After deleting the stats and re-analyzing so that stats on the non-indexed columns were not generated, the CBO always chose, at least on my test cases, to do an FTS on each and use an HJ. Anyway, as you mentioned, there might be other situations as well. Besides looking at the plans themselves, I also used information from Steve Adams' site, http://www.ixora.com.au/home.htm, for info on setting event 10053 and interpreting it's output so that I could "look" into the CBO's head and see how it evaluated and made it's decisions.

Sam p.s. if I missed the boat on this topic ,please ignore -Original Message- Sent: Friday, February 02, 2001 5:51 PM To: Multiple recipients of list ORACLE-L non-indexed columns Steve, Thanks for taking the time to reply. My initial thought was that the stats would be of no use, but, the thing that still makes me wonder is why would a simple "analyze table compute statistics" gather statistics on *all* columns. For this to be the default behavior, there could be a reason. That's why I threw the question out to the list, trying to see if I was overlooking something obvious. I see your answer below, but, one scenario hit me this morning and I thought I would run it by you and the list and let people take shots at it. Assume I have an SQL query joining two tables equal in size and the CBO views the cost of an FTS against either as being the same, and, there is an index supporting joining the tables. In addition to the join criteria, criteria against *non-indexed* columns in each of the two tables are specified. No *indexed* columns criteria, other than the join itself, is specified. So, the CBO needs to choose one of the tables as the "driving" table, doing an FTS, and, needs to decide whether to use an NL, MJ, or HJ between the two. Does it make sense, in this case, that the column stats for the non-indexed column could influence the choice of the driving table and/or the join method, that a generalized selectivity would be construed based on the number of distinct values captured for the columns? Sure, an FTS on at least one table would still be required, but, stats on the non-indexed columns could influence which table to drive by and which join method to use? My "gut" feeling is that in a case such as the one just described, stats on non-indexed columns could influence the access path and join method determined by the CBO. I picked up info on event 10053 from your site. I'll play around with that this weekend. Regards, Larry G.

If I check the V$log while updation in progress, I find the status is in ACTIVE even after the archive file written for that log. This sequence continues until all the log files except current one in ACTIVE state. After couple of minutes all the ACTIVE status getting changed to INACTIVE. Any Idea what could be the reason for this? I got 8.1.6 undex solaris.
