How to get the number of resultSets opened ?

Hi,
As I have a memory leak in my application, I wonder if there is a simple way to get the number of statements and resultsets opened to determine if it dramatically increases.
Thanks.

How to get the number of files currently open?

hi,
does any one know how to get the number of files currently open in windows OS?
e.g. lets say .txt files...
any comment will be really appreciated.
thanks

Assuming that you don't want to actually do this from within Java code (which would obviously require native code), here's a utility that will give you a list of which file handles are opened by which processes (on Windows):

How to get the number of columns in a result set???

hi everyone..
i am trying to establish a servlet applet communication....
my applet send the sql query to the servlet as serialised string and then the servlet executes the query...
Since i need to pass the result back to the applet, i thaught of passing the whole reult set to the applet..but that seems to be not possible..
so i thaught of storing my result set data in a vector and then pass the vector,but the first problem that i came across is that how to get the number of colums in a result set....
so is there a way to get the number of columns in a result set...???
and also i would like to know if it possible to send my whole result set to the applet bye serialization or by any method...???
thanx in advance

You shouldn't do. It expenses resources (you should always close the ResultSet and the Statement as fast as possible). Simply gently process it into a Collection or Map of DTO's. Those are serializable.

Hi,
There are lots of STATE is available for composite instances, like mentioned in the below query. I hope you will get answer from the below query.
SELECT (CASE WHEN STATE=1 THEN 'OPEN AND RUNNING'
WHEN STATE=2 THEN 'OPEN AND SUSPENDED'
WHEN STATE=3 THEN 'OPEN AND FAULTED'
WHEN STATE=4 THEN 'CLOSED AND PENDING'
WHEN STATE=5 THEN 'CLOSED AND COMPLETED'
WHEN STATE=6 THEN 'CLOSED AND FAULTED'
WHEN STATE=7 THEN 'CLOSED AND CANCELLED'
WHEN STATE=8 THEN 'CLOSED AND ABORTED'
WHEN STATE=9 THEN 'CLOSED AND STALE'
WHEN STATE=10 THEN 'NON-RECOVERABLE'
ELSE STATE || ''
END) AS STATE, component_name, COUNT(*) AS NUM_OF_CUBE_INST FROM CUBE_INSTANCE where composite_name='PASS THE COMPOSITE NAME HERE..........'
group by (CASE WHEN STATE=1 THEN 'OPEN AND RUNNING'
WHEN STATE=2 THEN 'OPEN AND SUSPENDED'
WHEN STATE=3 THEN 'OPEN AND FAULTED'

How to get the number of elements in DB

Could you tell me how to get the number of elements in DB??
My code to get the number is below, but I think it is not efficient
DB->cursor(DB, NULL, &cursorp, 0);
while ((ret = cursorp->c_get(cursorp, &key, &data, DB_NEXT)) == 0)
count++;
--------------------------------------------------------------------------------------------------------------

Hi,
The most efficient way to get a count from the database is using the DB->stat API (http://docs.oracle.com/cd/E17076_02/html/api_reference/C/dbstat.html)
The code will be something like:
        DB *dbp;
        DB_BTREE_STAT *statp;
        int ret;
        /* Print out the number of records in the database. */
        if ((ret = dbp->stat(dbp, NULL, &statp, 0)) != 0) {
                dbp->err(dbp, ret, "DB->stat");
                goto err1;
        printf("%s: database contains %lu records\n",
            progname, (u_long)statp->bt_ndata);
        free(statp);The code comes from the example included in the distribution at examples/c/ex_btrec.c
If the database isn't a btree, you should update to the appropriate statistics structure and field.
It's worth noting that retrieving the count is never a "cheap" operation. The count is not stored in the database - since doing so introduced a single point of contention that creates a bottle neck.

How to get the number of messages consumed by a MDB ??

Hi all,
How to get the number of messages consumed by a MDB displayed in OEM in a Java Application ???
DMS ??? what use DMS ???
tanks

ok.
Well using DMS is one way to get at these sorts of stats in a programmatic manner.
There's a Java API you can use, or you could call out to the Spy servlet to query the DMS stats in either text or XML form.
I don't have an MDB published so I can't show you specifiically, but here's the sort of query you can use to extract the data.
http://localhost:8888/dms0/Spy?format=raw&table=oc4j_ejb_stateless_bean&recurse=children
Which produces a table of the TEXT form:
<DMSDUMP version='9.0.4' timestamp='1163456821185 (Tue Nov 14 08:57:01 CST 2006)' id='8888' name='OC4J'>
<statistics>
/oc4j [type=n/a]
/oc4j/default [type=oc4j_ear]
/oc4j/default/EJBs [type=oc4j_ejb]
/oc4j/default/EJBs/jmsrouter_ejb [type=oc4j_ejb_pkg]
/oc4j/default/EJBs/jmsrouter_ejb/AdminMgrBean [type=oc4j_ejb_stateless_bean]
pooled.count: 11 ops
pooled.maxValue: 1 count
pooled.minValue: 0 count
pooled.value: 0 count
ready.count: 11 ops
ready.maxValue: 1 count
ready.minValue: 0 count
ready.value: 0 count
session-type.value: Stateless
transaction-type.value: Bean
/oc4j/default/EJBs/jmsrouter_ejb/EnqueuerBean [type=oc4j_ejb_stateless_bean]
pooled.count: 11 ops
pooled.maxValue: 0 count
pooled.minValue: 0 count
pooled.value: 0 count
ready.count: 11 ops
ready.maxValue: 0 count
ready.minValue: 0 count
ready.value: 0 count
session-type.value: Stateless
transaction-type.value: Bean
/oc4j/default/EJBs/jmsrouter_ejb/TimerHandlerBean [type=oc4j_ejb_stateless_bean]
pooled.count: 11 ops
pooled.maxValue: 0 count
pooled.minValue: 0 count
pooled.value: 0 count
ready.count: 11 ops
ready.maxValue: 0 count
ready.minValue: 0 count
ready.value: 0 count
session-type.value: Stateless
transaction-type.value: Bean
</statistics>
</DMSDUMP>
Or produces an XML document of the form:
http://localhost:8888/dms0/Spy?format=xml&table=oc4j_ejb_stateless_bean&recurse=children
You can use the Spy console to find the table that contains the details for MDB and then take it from there.
This is not what you specifically want to do, but it does provide a good overview of how DMS is used.

How to get the number of bytes at TCP port

Hi all,
How to get the number of bytes to read at the TCp port...as someone had suggested in some forum we do read the number of bytes first and then pass this...
but we get a problem when we have FF data in this...because then it sends 2 FF data...and cause of this we skip the last data...is there any solution for the same?

Hi
In LabVIEW you don't have the same property as in serail port.
You havn't "Byte at TCPIP port".
if you developp a protocol, one soltion, is to send the size to read.

I'm a little confused by the question, but it sounds like you're asking how to count the number of files with a particular extension in a given directory? That's not really an AI SDK question, but it's a fairly easy one to find if you google it. If you're trying to use Illustrator to do it, AI doesn't have a general purpose file API. It has a few functions to do some things that Illustrator needs, but I don't think enumerating directories is one of them.

How to get the number of rows in a ResultSet

Hello,
I'm an intern and I'm trying to get the number of rows from result set in oracle using rs.last() and rs.beforeFirst() methods
but I got an error. Could Below is my sample code:
import java.sql.*;
public class SarueckConnect {
public static void main(String[] args) {
Connection con = null;
Statement stmt = null;
ResultSet re = null;
String[] ParamArray;
ParamArray = new String[24];
//Properties logon;
try {
Class.forName("oracle.jdbc.driver.OracleDriver"); //Loading the Oracle Driver.
con = DriverManager.getConnection
("jdbc:oracle:thin:@258.8.159.215:1521:test_DB","data","data"); //making the connection DB.
stmt = con.createStatement ();// Sending a query string to the database
//stmt.executeUpdate("UPDATE test_table set steuk = 6 WHERE steuk = 5");
ResultSet rs = stmt.executeQuery("SELECT mandt,kokrs,werks,arbpl,aufnr,vornr,ile01,"+
"lsa01,ism01,ile02,lsa02,ism02,ile03,lsa03,ism03,ile04,lsa04,ism04,steuk,matnr,budat,"+
"kostl,pernr,rueckid FROM test_table where steuk =6");
//Print the result out.
rs.last(); //This is the line which gives an error.
int rows = rs.getRow();
rs.beforeFirst();// I presume this is wrong to.
ParamArray = new String[24*rows];
int counter=0;
while (rs.next()) {
for (int i = 1; i <= 24; i++){
ParamArray[i-1+(counter*24)] = rs.getString(i);
System.out.print(rs.getString(i) + '\t');
System.out.println();
counter++;
} catch(Exception e) {
e.printStackTrace();
} finally {
try
if(stmt != null) stmt.close();
if(con != null) con.close();
} catch (Exception exception) {
exception.printStackTrace();
TryBapi sap = new TryBapi(ParamArray);
}When I run the code I do have the following ERROR Message:
java.sql.SQLException: Invalid operation for forward only resultset : last

at SarueckConnect.main(SarueckConnect.java:28)Please could any body Help me out here to figure out how to correct this?
Any Help would be highly apprecited.

make your result set scrollable...Not such a good idea. With Oracle, the JDBC driver will read and cache all the ResultSet in memory (with other DBMSs/drivers the behavior will probably be different, but you will still have some unnecessary overhead).
You can do the caching yourself if you think it's worth it. If the piece of code you posted is why you need this for, then use a List or Vector and you won't need to know the size upfront.

How to get the number of rows in a DB-Cursor

When i open a database cursor i do not know how much rows are stored in the cursor. To solve this problem i have to send a 'select count(1) ...' to get the number of rows before i set up the cursor. I think that this is not very clever and could possibly cause performance problems. But i need the num of rows to show the percentage of processed rows. Is there any other way to get the num of rows? May be by checking the cursor directly?
Please help!
Thanx a lot

In order to find out how may rows are going to be processed, oracle has to visit every row. So with a cursor, there is no property that will accurately reflect the number of rows until you get to the last one. That said, you could use
select count(*) over() as row_count, <rest of your columns> FROM <your table>
which will give you the total row count agaist each row in the result set. There are performance penalties involved but they will be less than issuing the query twice, once to get the count and once to get the rows.
Have a look on asktom for some very usefull info about all this.

How to get the number of records of a streaming result set

Hi guys.
So if it wasn't a streaming result set, I would have done this:
{noformat}myResultSet<code class="jive-code jive-java">.last();
{color:navy}*int*{color} numResults = </code>myResultSet<code class="jive-code jive-java">.getRow();
</code>myResultSet<code class="jive-code jive-java">.beforeFirst();
</code>{noformat}
but being a streaming result set, beforeFirst() throws an exception...
So how do you get the number of records in that result set? I wanna avoid an extra count(*) query, so I would appreciate other solutions than that.

If you get an exception, then you surely have a stack trace. That should tell you what happens, or at least where.com.mysql.jdbc.MysqlIO.checkForOutstandingStreamingData(MysqlIO.java:2066)
Why do you need to know the number of elements beforehand, anyway?I need to know the number of elements because the incoming data goes into a table. Now of course, I could use ArrayList<String[]> or something, but wouldn't that require more memory resources than Object[][] ?
No one can tell you that, at least not without more information (say, the stack trace for example).Here's the exception message:
java.sql.SQLException: Streaming result set com.mysql.jdbc.RowDataDynamic@10c0ef2 is still active. Only one streaming result set may be open and in use per-connection. Ensure that you have called .close() on any active result sets before attempting more queries.

How to get the number of days in a month?

hi all
is there any way to get the number of days in a given month with a given year? for instance, if year is 2004 and the month is July or February, how can i get the number of days? thanks.

Gee, I don't know ... Maybe this:
Calendar cal = Calendar.newInstance();
cal.set(Calendar.YEAR, 2004);
cal.set(Calendar.MONTH, Calendar.FEBUARY);
System.out.println("max days in month: " + cal.getActualMaximum(Calendar.DAY_OF_MONTH));
Do you not bother reading what people have already posted? Read the API docs on the Calendar class.
