Implicit vs explicit close of resultsets and statements?
Hi friends.I am a newbie Java Developer..Okay Here goes
I have just made a LAN based Java application using Swing,JDBC with backend as MS-Access..The backend is on a shared network drive..
The application is distributed as jar files on the LAN PCs..
Everywhere I have connected to the database I have just closed the connection explicitly like this
con.close();
I do not close the associated resultset and statement explicitly
The specification says associated statements and resultsets close when you close
the connection,even if you don't explicitly close them
Also I am not using connection pool..its simple basic connection using DriverManager
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String url = "jdbcdbcSN name";
String user = "";
String pw = "";
con = DriverManager.getConnection(url, user, pw);
Statement stmt = con.createStatement();
String select = "" ;
ResultSet rows = stmt.executeQuery(select);
On the net everyone says to explicitly close everything..but I did not know that
earlier..
If specification says everything closes on
closing connection why do ppl insist on closing everything explicitly..?
Or is this driver dependent..don't the drivers go through the specification..
My driver is the Sun JDBC ODBC bridge.....
I found this method DriverManager.setLogwriter()
It prints out a trace of all JDBC operations..
So I ran a sample program with this method included...
I redirected output to a log file..
In that program I just explicitly close the connection without closing the
statements and resultsets explicitly...
After running the program and seeing the log I saw that the statements
and resultsets are closed implicitly If I just close the connection explicitly..
I am putting the log file and the code..
Have a look at the end of the log file..
Code
import java.sql.;
import java.io.;
class gc4test
public static void main(String args[])
Connection con = null;
try
FileWriter fwTrace = new FileWriter("c:\\log.txt");
PrintWriter pwTrace= new PrintWriter(fwTrace);
DriverManager.setLogWriter(pwTrace);
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
String url = "jdbc:odbc:pravahcon";
String user = "admin";
String pw = "ash123";
con = DriverManager.getConnection(url, user, pw);
Statement stmt = con.createStatement();
Statement stmt1 = con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
Statement stmt2 = con.createStatement();
Statement stmt3 = con.createStatement();
Statement stmt4 = con.createStatement();
Statement stmt5 = con.createStatement();
Statement stmt6 = con.createStatement();
Statement stmt7 = con.createStatement();
String select = "SELECT * FROM Users" ;
ResultSet rows = stmt.executeQuery(select);
ResultSet rows1 = stmt1.executeQuery(select);
while(rows.next())
con.close();
catch (ClassNotFoundException f)
System.out.println(f.getMessage());
System.exit(0);
catch (SQLException g)
System.out.println(g.getMessage());
System.exit(0);
catch (Exception e)
System.out.println(e.getMessage());
System.exit(0);

Closing resultset and statements
Hi!
I just got told that I do not need to close my resultsets and statements in the code, it it enough that the connection are closed. Is this correct?
Eg:
public method myMethod() {
ResultSet rs = null;
Statement sqlStmt = null;
try {
query = "SELECT something";
rs = sqlStmt.executeQuery(query);
if (rs.next())
do something...
// close rs
if (rs != null) {
rs.close();
rs = null;
sqlStmt.close();
sqlStmt = null;
} // end try
catch (errors)...
finally {
if (con != null) { <-- Is this line enough to close everything and release connections?
try {
con.close();
catch (exception)...
} // end finallyNo, you have to explicitly close the resultset, statement, and connection in order to release resources allocated to each of them. Closing the connection will only relase the connection, not the resultset, and statement.
you could do all of it in the finally as follows:
finally {
try {
if (rs != null) {
rs.close();
if (stmt != null) {
stmt.close();
if (conn != null) {
conn.close();
} catch (Exception e) {}
also there is no need to set rs = null, stmt = null after the close() -
Why should we have to close the result set and statement
I am told that , I have to close my connection , result set , statement objects in finally block.
why we need to do this ?
If close the connection wont it be sufficient?To ensure that resources are freed in the client and in the database server.
Yes, closing the connection is enough. Except if you are a bit paranoid about broken JDBC drivers that don't close dependent resources properly - but I haven't seen such drivers in real life.
One important reason why programmers close ResultSets and Statements is that they use connection pools. In that case the Connection is returned to the pool instead of closing it. It is good practice to close RS's and Statements in preparation for the day when you graduate to writing code where you too will want to use a connection pool instead of the sloooooow reconnect-close-reconnect-close-etc. -
Too many connections - even after closing ResultSets and PreparedStatements
I'm getting a "Too many connections" error with MySQL when I run my Java program.
2007-08-06 15:07:26,650 main/CLIRuntime [FATAL]: Too many connections
com.mysql.jdbc.exceptions.MySQLNonTransientConnectionException: Too many connections
at com.mysql.jdbc.SQLError.createSQLException(SQLError.java:921)

at com.mysql.jdbc.MysqlIO.checkErrorPacket(MysqlIO.java:812)
at com.mysql.jdbc.MysqlIO.secureAuth411(MysqlIO.java:3269)
at com.mysql.jdbc.MysqlIO.doHandshake(MysqlIO.java:1182)
at com.mysql.jdbc.Connection.createNewIO(Connection.java:2670)I researched on this and found out that I wasn't closing the ResultSet and the PreparedStatement.
The JDBC connection is closed by a central program that handles connections (custom connection pooling).
I added the code to close all ResultSets and PreparedStatements, and re-started MySQL as per the instructions here
but still get "Too many connections" error.
A few other things come to mind, as to what I may be doing wrong, so I have a few questions:
1) A few PreparedStatements are created in one method, and they are used in a 2nd method and closed in the 2nd method
does this cause "Too many connections" error?
2) I have 2 different ResultSets, in nested while loops where the outer loop iterates over the first ResultSet and
the inner loop iterates over the second ResultSet.
I have a try-finally block that wraps the inner while loop, and I'm closing the second ResultSet and PreparedStement
in the inner while loop.
I also have a try-finally block that wraps the outer while loop, and I'm closing the first ResulSet and PreparedStatement
in the outer while loop as soon as the inner while loop completes.
So, in the above case the outer while loop's ResultSet and PreparedStatements remain open until the inner while loop completes.
Does the above cause "Too many connections" error?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The following is relevant sections of my code ( it is partially pseudo-code ) that shows the above 2 cases:
init( Connection jdbcConnection ){
String firstSQLStatement = "....";
PreparedStatement ps1 = jdbcConnection.prepareStatement( firstSQLStatement );
String secondSQLStatement = "....";
PreparedStatement ps2 = jdbcConnection.prepareStatement( secondSQLStatement );
String thirdSQLStatement = "....";
PreparedStatement ps3 = null;
ResultSet rsA = null;
try{
ps3 = jdbcConnection.prepareStatement( thirdSQLStatement );
rsA = ps3.executeQuery();
if( rsA.next() ){
rsA.getString( 1 );
}finally{
if( rsA != null )
rsA.close();
if( ps3 != null )
ps3.close();
//Notice, how ps1 and ps2 are created here but not used immediately, but only ps3 is
//used immediately.
//ps1 and ps2 are used in another method.
run( Connection jdbcConnection ){
ResultSet rs1 = ps1.executeQuery();
try{
while(rs1.next()){
String s = rs1.getString();
ps2.setString(1, s);
ResultSet rs2 = ps2.executeQuery();
try{
while(rs2.next()){
String s2 = rs2.getString();
}finally{
if( rs2 != null )
rs2.close();
if( ps2 != null )
ps2.close();
}catch( Exception e ){
e.printStackTrace();
}finally{
if( rs1 != null )
rs1.close();
if( ps1 != null )
ps1.close();
//Notice in the above case rs1 and ps1 are closed only after the inner
//while loop completes.
}I appreciate any help.Thanks for your reply.
I will look at the central connection pooling mechanism ( which was written by someone else) , but that is being used by many other Java programs others have written.
They are not getting this error.
An addendum to my previous note, I followed the instructions here.
http://dev.mysql.com/doc/refman/5.0/en/too-many-connections.html
There's probably something else in my code that is not closing the connection.
But I just wanted to rule out the fact that opening a PreparedStatement in one method and closing it in another is not a problem.
Or, if nested ResultSet loops don't cause the problem.
I've read in a few threads taht "Too many connections" can occur for unclosed RS and PS , and not just JDBC connections. -
Connection/ResultSets/Prepared Statement opening and closing
Hi all another question that was sparked by a thread that I recently read. I believe it was duffmo who got the code from jverd. The code I am referring to is to have an open and close connection specified in a Utility or Database class. I wanted to know if there was any issues with having methods that open and close connections/result sets/ preparedStatements. Currently I am putting the finally blocks inside each of my methods. There is obvious benefits to putting the methods in a class on their own (namely code re-use) but I wanted to know if there are any dangers. (This may seem like a dumb question, but I've found from experience it's the things that you don't know that will cost you loads of time).
thanks again.Hi all another question that was sparked by athread
that I recently read. I believe it was duffmo who
got the code from jverd. Generally speaking it's fine.
But as always you may have some long term design
issues to think about. If you build a simple
framework that consists of one class and that does
all that your program does then great.
Once you start add more complexity though you'll want
to be careful that you aren't reinventing the Spring
wheel or even ending up implementing your own
connection pool. Both of which, judging from posts
here seem to happen from time to time.
So I guess all in all, yes it's much better than
scattering the code all about but depending on what
you are going to be doing with it you may want to
look at the various ORM frameworks to see if they are
really the direction you should be going in.Thanks for the information cotton. I just wanted to make certain that it was a sensible thing to do. When I had first asked about connections I was told they should be opened an closed in the same spot, unfortunately I took that explanation a little too much to heart, and started opening and closing every connection resultset and prepared statement in each of the DAO classes that I was using.
Guess it's going to be a bit of work to refactor, but worth it for the cleaner code that will result. -
Why to need close the result set and statement
why to need close the result set and statement
It's best to explicitly close every ResultSet, Statement, and Connection in the narrowest scope possible.
These should be closed in a finally block.
Since each close() method throws SQLException, each one should be in an individual try/catch block to ensure that a failure to close one won't ruin the chances for all the others.
You can capture this in one nice utility class, like this:

Do a search on problems with Oracle cursors being exhausted and learn what the root cause is. That should convince you.

Problem with store ResultSet and show result in table
Hi, I'm kind of new in ADF, I need to store ResultSet and show result in table-component. I have two problems:
1) I get my ResultSet by calling callStoredProcedure(...) and this returns actually ref_cursor as ResultSet.
When I try to println() contains of this result set in this method - it works OK (commented part),
but when I want to println() somewhere else (eg. in retrieveRefCursor() method) it doesn't work.
The problem is that the scrollability of the ResultSet is lost - it becomes a TYPE_FORWARD_ONLY ResultSet.
Is there any way to store data from ref_cursor for a long time?
2) My second problem is "store any result set and show this data in table". I have tried use method storeNewResultSet() but
without result (table contains only "No rows yet" and everything seems to be OK - no exception, no warning, no error...).
I have tried to call this method with ResultSet from select on dbs (without resultSet as ref_cursor ) - no result with createRowFromResultSet(),
storeNewResultSet(), setUserDataForCollection()...
I've tried a lot of ways to do this, but it doesn't work. I really don't know how to make it so it can work.
Thanks for your help.

Open cursors are NOT closed only by closing the ResultSet or Statement
I've realised that the open cursors are only closed by closing the connection.
In my example code I have for-loop with a vector of table-names. For every table-name I start a query to retrieve metainformation (row-size, column-names). Although I close the ResultSet (which automatically closes the PreparedStatement/Statement) I reached after the 150th loop a max-cursor-exception (ora-01000) ?!
It seems that there is only the workaround to close and re-open the connection at the end of the for-loop. Which is performance-side pretty bad :-(.
Is there really no other solution?
Besides: does anyone know WHY the statement.close() also closes the ResultSet?? I think this is a bad design (hence to tight dependency between both classes). What if the garbage collector closes the statement (and hence to the JDOC the statement.close()-method also closes the ResultSet)? For example if a method uses a local Statement and returns a ResultSet (and the Statement-garbage is collected), then the ResultSet would cause an exception?!
Thanks for the help in advance

retrieve metainformation (row-size, column-names).
Although I close the ResultSet (which automatically
closes the PreparedStatement/Statement) I reached
after the 150th loop a max-cursor-exception
(ora-01000) ?!Closing the ResutSet does not automatically close the PreparedStatement/Statement.
>
It seems that there is only the workaround to close
and re-open the connection at the end of the for-loop.
Which is performance-side pretty bad :-(.
Is there really no other solution?
Just explicitly close the PreparedStatement/Statement!
Besides: does anyone know WHY the statement.close()
also closes the ResultSet?? You need to think of a resultset as a live connection to the database.
Consider SELECT * FROM ABIGTABLE, it would be inefficient to populate the Resultset with all of the rows (could even eat up all memory) so the first n rows are returned ( n = Statement.getFetchSize() ) and the next n rows are returned as needed.
I think this is a bad
design (hence to tight dependency between both
classes). What if the garbage collector closes the
statement (and hence to the JDOC the
statement.close()-method also closes the ResultSet)?
For example if a method uses a local Statement and
returns a ResultSet (and the Statement-garbage is
collected), then the ResultSet would cause an
exception?!You should use a statment and resultset, read all your data into a collection or a CachedRowSet (http://www.javaworld.com/javaworld/jw-02-2001/jw-0202-cachedrow.html) then close the statment as soon as possible. Never return a resultset form your data tier: that is tight coupling between the tiers of your application! -
Trap string output from resultset and pass the value to getSchema.
I want to get the string ldb output frm the resultset and pass it to getSchemas(ldb).kindly let me know how to do it,right now it is throwing error like variable ldb might not have been initialised.

Need help with inserting rows in ResultSet and JTable
hello Guru!
i have inserted a row in my result set and i want that my table shows this row promptly after i have inserted it in my result set...
but when i use following code for my resultset:
rs.moveToInsertRow();
rs.updateInt(1,nr);
rs.updateString(2, name);
rs.insertRow();
Record are inserted in resultset and database but not shown in my JTable??
Anyone a Clue to without reexecuting the query how can i display inserted row in JTable

Seeing Database Changes Made Internally and Externally
This section discusses the ability of a result set to see the following:
its own changes (DELETE, UPDATE, or INSERT operations within the result set), referred to as internal changes
changes made from elsewhere (either from your own transaction outside the result set, or from other committed transactions), referred to as external changes
Near the end of the section is a summary table.
Note:
External changes are referred to as "other's changes" in the Sun Microsystems JDBC 2.0 specification.
Seeing Internal Changes
The ability of an updatable result set to see its own changes depends on both the result set type and the kind of change (UPDATE, DELETE, or INSERT). This is discussed at various points throughout the "Updating Result Sets" section beginning on , and is summarized as follows:
Internal DELETE operations are visible for scrollable result sets (scroll-sensitive or scroll-insensitive), but are not visible for forward-only result sets.
After you delete a row in a scrollable result set, the preceding row becomes the new current row, and subsequent row numbers are updated accordingly.
Internal UPDATE operations are always visible, regardless of the result set type (forward-only, scroll-sensitive, or scroll-insensitive).
Internal INSERT operations are never visible, regardless of the result set type (neither forward-only, scroll-sensitive, nor scroll-insensitive).
An internal change being "visible" essentially means that a subsequent getXXX() call will see the data changed by a preceding updateXXX() call on the same data item.
JDBC 2.0 DatabaseMetaData objects include the following methods to verify this. Each takes a result set type as input (ResultSet.TYPE_FORWARD_ONLY, ResultSet.TYPE_SCROLL_SENSITIVE, or ResultSet.TYPE_SCROLL_INSENSITIVE).
boolean ownDeletesAreVisible(int) throws SQLException
boolean ownUpdatesAreVisible(int) throws SQLException
boolean ownInsertsAreVisible(int) throws SQLException
Note:
When you make an internal change that causes a trigger to execute, the trigger changes are effectively external changes. However, if the trigger affects data in the row you are updating, you will see those changes for any scrollable/updatable result set, because an implicit row refetch occurs after the update.
Seeing External Changes
Only a scroll-sensitive result set can see external changes to the underlying database, and it can only see the changes from external UPDATE operations. Changes from external DELETE or INSERT operations are never visible.
Note:
Any discussion of seeing changes from outside the enclosing transaction presumes the transaction itself has an isolation level setting that allows the changes to be visible.
For implementation details of scroll-sensitive result sets, including exactly how and how soon external updates become visible, see "Oracle Implementation of Scroll-Sensitive Result Sets".
JDBC 2.0 DatabaseMetaData objects include the following methods to verify this. Each takes a result set type as input (ResultSet.TYPE_FORWARD_ONLY, ResultSet.TYPE_SCROLL_SENSITIVE, or ResultSet.TYPE_SCROLL_INSENSITIVE).
boolean othersDeletesAreVisible(int) throws SQLException
boolean othersUpdatesAreVisible(int) throws SQLException
boolean othersInsertsAreVisible(int) throws SQLException
Note:
Explicit use of the refreshRow() method, described in "Refetching Rows", is distinct from this discussion of visibility. For example, even though external updates are "invisible" to a scroll-insensitive result set, you can explicitly refetch rows in a scroll-insensitive/updatable result set and retrieve external changes that have been made. "Visibility" refers only to the fact that the scroll-insensitive/updatable result set would not see such changes automatically and implicitly.
Visibility versus Detection of External Changes
Regarding changes made to the underlying database by external sources, there are two similar but distinct concepts with respect to visibility of the changes from your local result set:
visibility of changes
detection of changes
A change being "visible" means that when you look at a row in the result set, you can see new data values from changes made by external sources to the corresponding row in the database.
A change being "detected", however, means that the result set is aware that this is a new value since the result set was first populated.
With Oracle8i release 8.1.6 and higher, even when an Oracle result set sees new data (as with an external UPDATE in a scroll-sensitive result set), it has no awareness that this data has changed since the result set was populated. Such changes are not "detected".
JDBC 2.0 DatabaseMetaData objects include the following methods to verify this. Each takes a result set type as input (ResultSet.TYPE_FORWARD_ONLY, ResultSet.TYPE_SCROLL_SENSITIVE, or ResultSet.TYPE_SCROLL_INSENSITIVE).
boolean deletesAreDetected(int) throws SQLException
boolean updatesAreDetected(int) throws SQLException
boolean insertsAreDetected(int) throws SQLException
It follows, then, that result set methods specified by JDBC 2.0 to detect changes--rowDeleted(), rowUpdated(), and rowInserted()--will always return false with the 8.1.6 Oracle JDBC drivers. There is no use in calling them.
Summary of Visibility of Internal and External Changes
Table 12-1 summarizes the discussion in the preceding sections regarding whether a result set object in the Oracle JDBC implementation can see changes made internally through the result set itself, and changes made externally to the underlying database from elsewhere in your transaction or from other committed transactions.
Table 12-1 Visibility of Internal and External Changes for Oracle JDBC

For implementation details of scroll-sensitive result sets, including exactly how and how soon external updates become visible, see "Oracle Implementation of Scroll-Sensitive Result Sets".
Notes:
Remember that explicit use of the refreshRow() method, described in "Refetching Rows", is distinct from the concept of "visibility" of external changes. This is discussed in "Seeing External Changes".
Remember that even when external changes are "visible", as with UPDATE operations underlying a scroll-sensitive result set, they are not "detected". The result set rowDeleted(), rowUpdated(), and rowInserted() methods always return false. This is further discussed in "Visibility versus Detection of External Changes".
Oracle Implementation of Scroll-Sensitive Result Sets
The Oracle implementation of scroll-sensitive result sets involves the concept of a window, with a window size that is based on the fetch size. The window size affects how often rows are updated in the result set.
Once you establish a current row by moving to a specified row (as described in "Positioning in a Scrollable Result Set"), the window consists of the N rows in the result set starting with that row, where N is the fetch size being used by the result set (see "Fetch Size"). Note that there is no current row, and therefore no window, when a result set is first created. The default position is before the first row, which is not a valid current row.
As you move from row to row, the window remains unchanged as long as the current row stays within that window. However, once you move to a new current row outside the window, you redefine the window to be the N rows starting with the new current row.
Whenever the window is redefined, the N rows in the database corresponding to the rows in the new window are automatically refetched through an implicit call to the refreshRow() method (described in "Refetching Rows"), thereby updating the data throughout the new window.
So external updates are not instantaneously visible in a scroll-sensitive result set; they are only visible after the automatic refetches just described.
For a sample application that demonstrates the functionality of a scroll-sensitive result set, see "Scroll-Sensitive Result Set--ResultSet5.java".
Note:
Because this kind of refetching is not a highly efficient or optimized methodology, there are significant performance concerns. Consider carefully before using scroll-sensitive result sets as currently implemented. There is also a significant tradeoff between sensitivity and performance. The most sensitive result set is one with a fetch size of 1, which would result in the new current row being refetched every time you move between rows. However, this would have a significant impact on the performance of your application.

Need to explicity close ref cursor?
Happy Friday. I've been trying to test out this one myself, but the results are inconclusive, sooo... Say if you declare a cursor and a ref cursor as rowtype of that cursor in the specification of a package, and in the body if you 'open cursor for', have you then got to explicity close the cursor?
If anyone's got a query against the v$ tables that would prove/disprove the above it would be much appreciated.
Thanks in advance.Oracle (aka PL/SQL engine) has a garbage collector. It will close cursor handles when that handle goes out of scope.
So you need not close explicit cursor handles for example that is defined in a local scope (though it is good programming practice to do so), whereas you should close it when that cursor handle resides within the scope of a package's state. (i.e. defined in the package header or body as a global)
Ref cursors otoh are special - as they have no local scope. Only session scope. So as long as that Oracle session exist, that ref cursor created in that session will exist, until explicitly closed. Why? Because ref cursors are intended to be use by the client of that session - which means that irrespective of what happens scope wise on the PL/SQL engine side, that ref cursor handle must "survive" as it can (and often is) used by the client.
This is also the primary cause for cursor leakage. Clients (especially Java apps in my experience) use ref cursors - but forget to close them after use. The open cursor handle count quickly runs up and an ORA error results.. with the Java developers then thinking there is something wrong with Oracle and that the max number of cursor handles per session should be increased.
PS. typing this on my home console (Windows) and not work machine (Linux), so unfortunately no SQL code snippets.. but you can have a look at the Reference Manual and look for the V$ cursor views. There is an open cursor view that lists open cursors per session - just note that garbage collection can happen at the start of the next call and not at the end of the last call.. if I recall correctly. Which at times make the results look "funny" when tracing open cursor handles. -
Need help Take out the null values from the ResultSet and Create a XML file
hi,
I wrote something which connects to Database and gets the ResultSet. From that ResultSet I am creating
a XML file. IN my program these are the main two classes Frame1 and ResultSetToXML. ResultSetToXML which
takes ResultSet & Boolean value in its constructor. I am passing the ResultSet and Boolean value
from Frame1 class. I am passing the boolean value to get the null values from the ResultSet and then add those
null values to XML File. When i run the program it works alright and adds the null and not null values to
the file. But when i pass the boolean value to take out the null values it would not take it out and adds
the null and not null values.
Please look at the code i am posing. I am showing step by step where its not adding the null values.
Any help is always appreciated.
Thanks in advance.

After installing yosemite on my laptop, once I open the internet through Safari, it at times will freeze or discontinue working causing me to close the wifi and turn it back on then reload the internet page to get it to work again. Is there any way to fix this?
1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
The test works on OS X 10.7 ("Lion") and later. I don't recommend running it on older versions of OS X. It will do no harm, but it won't do much good either.
Don't be put off by the complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. As I wrote above, it changes nothing. It doesn't send or receive any data on the network. All it does is to generate a human-readable report on the state of the computer. That report goes nowhere unless you choose to share it. If you prefer, you can act on it yourself without disclosing the contents to me or anyone else.
You should be wondering whether you can believe me, and whether it's safe to run a program at the behest of a stranger. In general, no, it's not safe and I don't encourage it.
In this case, however, there are a couple of ways for you to decide whether the program is safe without having to trust me. First, you can read it. Unlike an application that you download and click to run, it's transparent, so anyone with the necessary skill can verify what it does.
You may not be able to understand the script yourself. But variations of it have been posted on this website thousands of times over a period of years. The site is hosted by Apple, which does not allow it to be used to distribute harmful software. Any one of the millions of registered users could have read the script and raised the alarm if it was harmful. Then I would not be here now and you would not be reading this message. See, for example, this discussion.
Nevertheless, if you can't satisfy yourself that these instructions are safe, don't follow them. Ask for other options.
4. Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
5. Try to test under conditions that reproduce the problem, as far as possible. For example, if the computer is sometimes, but not always, slow, run the test during a slowdown.
You may have started up in "safe" mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
6. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
7. The script is 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, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
8. 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 and start typing the name.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
9. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
exec bash
and press return. Then paste the script again.
10. 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 the password, the test will run anyway, but it will produce less information. If you don't know the password, or if you prefer not to enter it, just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
11. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, a series of lines will appear in the Terminal window like this:
[Process started]
Part 1 of 8 done at … sec
Part 8 of 8 done at … sec
The test results are on the Clipboard.
Please close this window.
[Process completed]
The intervals between parts won't be exactly equal, but they give a rough indication of progress. The total number of parts may be different from what's shown here.
Wait for the final message "Process completed" to appear. If you don't see it within about ten minutes, the test probably won't complete in a reasonable time. In that case, press the key combination control-C or command-period to stop it and go to the next step. You'll have incomplete results, but still something.
12. When the test is complete, or if you stopped it because it was taking too long, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with the words "Start time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
13. When you post the results, you might see an error message on the web page: "You have included content in your post that is not permitted," or "You are not authorized to post." That's a bug in the forum software. Please post the test results on Pastebin, then post a link here to the page you created.
14. This is a public forum, and others may give you advice based on the results of the test. They speak for themselves, not for me. The test itself is harmless, but whatever else you're told to do may not be. For others who choose to run it, I don't recommend that you post the test results on this website unless I asked you to.

Copy the below code and save it as PrintServerState.java,
I also have copied the code from

PrintServerState s = new PrintServerState();
initConnection(hostname, portString, username, password);
s.printNameAndState();
connector.close();
Now compile it as javac -d . PrintServerState.java
Then Execute WL_HOME/weblogic92/server/bin/setWLSEnv.sh
Now Execute ur class file generated as
java -classpath .:WL_HOME/weblogic92/server/lib/wljmxclient.jar PrintServerState ipaddress port username password
The output will be as follows
Server name: Server3. Server state: RUNNING
Server name: Server2. Server state: RUNNING
Server name: Server1. Server state: RUNNING
Server name: Server4. Server state: RUNNING
