OracleXML SQL utility out of memory
when selecting from a latge table.
What can I do to fix this:
java.lang.OutOfMemoryError
I would appreciate any input.
You can use the XMLGEN.getXML() to retrieve the XML as a CLOB instead of as an in-memory DOM tree.
The next release of XML SQL Utility supports stream output and SAX2 events as output as well, which are both ways of circumventing the memory usage of a DOM tree for large datasets.

XML PL/SQL Parser Out of memory
Im parsing a 20M file and recieving the following result.
I have tried to cut the file size down and have found a small
version that will parse successfully.
We have tried adjusting
the ulimit -d 2097152
ulimit -s 32768
and also set java_pool_size = 41943040 in init.ora
none of these seemed to be enough to enable parsing of the file.
The following are 2 executions of the parser using 2 different
file sizes.
Thanks,
Steve

HOWTO: Writing Out XML Query Results of Any Size in Java with XML SQL Utility
A customer mailed me asking for an example of how to use our XML SQL Utility to write out query results for tons of query result rows.
With tons of data, the getXMLDOM() and getXMLString() methods are not really appropriate due to the size.
The XML SQL Utility offers a getXMLSAX() method that streams SAX2 events to report the data being queried. This is the approach we can use to handle data of any size.
It dawned on me today that by putting together the XML SQL Utilities getXMLSAX() routine, and the oracle.xml.parser.v2.XSLSAXPrintDriver SAX2 ContentHandler, we can effectively stream out data of any length to an appropriate writer.
Here's a code example to get the point across:
package test;
import java.io.BufferedOutputStream;
import java.io.PrintWriter;
import java.sql.Connection;
import java.sql.Driver;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.util.Properties;
import javax.xml.transform.OutputKeys;
import oracle.jdbc.OracleDriver;
import oracle.xml.parser.v2.XSLException;
import oracle.xml.parser.v2.XSLOutput;
import oracle.xml.parser.v2.XSLSAXPrintDriver;
import oracle.xml.sql.query.OracleXMLQuery;
public class Example {
private static final String QUERY = "select * from emp";
public static void main(String[] args) throws Throwable {
Connection conn = getConnection();
OracleXMLQuery q = new OracleXMLQuery(getConnection(),QUERY);
// Any printwriter will do. Here's we're output to standard out.
PrintWriter output = new PrintWriter(new BufferedOutputStream(System.out));
// This is a SAX2 Content Handler used by the Oracle XSLT Engine
// to serialize a stream of sax2 events as an XML document
// We'll use it to serialize the sax2 events from the XML SQL Utility
// out as an XML document.
XSLSAXPrintDriver ch = new XSLSAXPrintDriver(output, outputOptions());
// This asks XML SQL Utility to fire sax events for the data
// being fetched instead of creating DOM nodes or returning text.
// By using the XSLSAXPrintDriver content handler, these events
// get handled by writing them directly to the output stream
q.getXMLSAX(ch);
ch.flush();
q.close();
conn.close();
private static XSLOutput outputOptions() throws XSLException {
XSLOutput x = new XSLOutput();
Properties props = new Properties();
props.put(OutputKeys.METHOD,"xml");
props.put(OutputKeys.INDENT,"yes"); // Set to "no" for non-indented
x.setProps(props);
return x;
public static Connection getConnection() throws SQLException {
String username = "scott";
String password = "tiger";
String thinConn = "jdbc:oracle:thin:@localhost:1521:ORCL";
Driver d = new OracleDriver();
return DriverManager.getConnection(thinConn,username,password);
}Hi Uber,
This is a known issue that error occurs when running report "Count of instances of specific software registered with Add or Remove Programs" due to non-printable characters for XML. Based on internal research, the hotfix for this issue will be
included in the System Center 2012 Configuration Manager Service Pack 1.
As a workaround, you can remove the nonprintable character populated into the report parameter by referring to the following KB article:
http://support.microsoft.com/KB/914159
Hope this helps.

I am worried about the speed...
is it because of the large amount of data.. 23,355,459 records..?? or there could be some issue in programming probably memory leak etc..??

Out of memory Error while querying SQL Script based Calculation View
Hi All,
I wanted to test the performance of Graphical and SQL Script based Calculation views.
Created Graphical (CA_GRPH) and SQL Script (CA_SQL) Calculation views.
Analytic View (AN_GRPH) for both Calculation views are the same which is Graphical based (90 Attributes and 5 Measures)
In Analytic View data foundation I have a Fact table which has 1.5 Billion records and 9 Dimension Tables –collectively 500 million records (7 Attribute Views). 9 Referential joins with cardinality N:1 and 1 Referential join with cardinality N:N.
I wanted to keep (CA_GRPH) and (CA_SQL) as a base Calculation views and leverage those to create various calculation views (Will be creating different Calc views for respective Business segments)
In order to test this I have created below calc views on top of base calc views.
Graphical Based: Created (CA_GRAPH_XYZ) by having CA_GRPH in projection with 30 Calculated Columns. – This retrieves data in 13 secs
SQL Script Based: Created (CA_GRPH_ABC) by having CA_SQL in projection view with 30 calculated columns – This errors out after 1.50 mins.
Could not execute 'SELECT "COLUMN_A","COLUMN _B"," COLUMN _C"," COLUMN _D", SUM("COLUMN _REVENUE") AS ...' in 1:50.480 minutes .
SAP DBTech JDBC: [2048]: column store error: [2048] column store error: search table error: [1000002] Error executing physical plan: exception 1000002:

Any suggestion / help in fixing this issue will be greatly appreciated.
Regards,
AvHi Raj,
Thanks for your time, please find edited snap hot of Analytic View (AN_GRPH) below,
Calculation view(CA_SQL)
/********* Begin Procedure Script ************/
BEGIN
var_out =

"COLUMN_1"
"COLUMN_2",

END
/********* End Procedure Script ************/
Later i have built one more Calculation view(CA_GRPH_ABC) using (CA_SQL)in projection. i have 30 calculated measures in this final calc view. this final calc view is throwing above mentioned error.
Not sure if i can use SQL script based calc view in graphical based calc views?

How can I solve out of memory error on excell file in PL/SQL
Hi,
I'm new on PL/SQL. One of the PL/SQL code which is created excell report got out of Memory error. The first reason of this error, excell file not supported more than 65536 data. So I change the excell file separeted sheets. So that the single sheet size cannot exceed 65536 data.
All the data are held on system cach and if many user want to take the report the they would get an out of memory error.
So I want to change the code like that; when out of memory exception raises,
the old excell file save to disk and new excell file is created,
and go on to write the new file without exiting the program.
At the end of the data all the excell file append and show only one file to the user.
I do know how to save the file and create a new file. But I don't know how can PL/SQL program to turn back to loop again when the exception occurs.
Is anyone help me on this issue?
Here is my code
Thank you
dworkbook:=hssfworkbook.new;
dCurrentItem := Get_Block_Property(pCurrentBlock, FIRST_ITEM);
while not (name_in('system.last_record')='TRUE') loop
/* The data would be written to the excell file column order. */
if (dRow=0) then
/* Create a new sheet */
elsif (dRow <= dMaxWorksheetNum) then
/* Data of the report are written here. The data are written in column order */
if (dRow > dMaxWorksheetNum) then
/* give dRow and dColumn intial value */
/* increase worksheet number */
end if; /* End of if (dRow=1) */
if (isWritten) and not name_in('system.last_record')='TRUE'then
/* if not at the end of the record and the previously read record is written to the file
, then go to next record */
next_record;
end if;
/* save excell report */
workbookwriter.save(dworkbook,global.gethome||dFileName);
web.show_document('/users/'||dFileName,'_BLANK');
/* when exceptions occurs */

SQL Developer 3.1 out of memory
I new to SQL developer and I been trying to copy data between servers and i run out of memory a lot of times.
And i see that it happens with tables with more than 1 mill rec and got clob etc in it.
I had to write my own program to handle it and i found on the way i got the same problem in the beginning.
So my question is there a setting where i can tell the source (maybe the master also ) internal cursor to refetch the current position after say 10k records. I found doing that releases the memory of the inserted records so i can can continue to add more.
Im running a fetch rownumber on master and reset the source every 20k record so i hit maybe 120 meg memory usage and if i did not do that i seen the memory go up to 2 gig and im only running the server and the app at 4 gig so I crashed all the time.
By using this in my program I have copied 60 tables and 6 gig+ of data and no crash.
Thanks,
RogerYes it's helpful so you dont have to use the command prompt to create a dump file.
I was using the Database Copy to avoid having to move files to other server that i might not have system access to, only DB access.
I'm pretty new at using Oracle and I have one DB that needs to move data to other DB without having to write a extra program for it. It also seems that DBLinks does not handle blob/clob either and setting up a stream might not be available.
Thanks,
Roger -
DB SQL API for BDB: out of memory
Hi,
I posted a related thread here: Report Bug of SQLite-compatible API: Out of Memory Error but it is not answered yet so I am posting it again...Sorry for duplicate.
Basically, we are evaluating Berkeley DB as a candidate for our database solution. However, we ran into an out-of-memory error when using BDB's SQLite-compatible API to deal with memory databases. Here are some simple steps to repro the issue:
1. Open a memory database
2. Insert many records (about 200,000 records) into it
3. Close the database
4. Repeat from step 1.
Expected result: because I already closed the previous memory database, there should be no error.
Actual result: out of memory.
Here's the test program I am using:
int
testMemoryDatabase()
db_handle *db;
const char *sql;
int i;
// Setup database
db = setup(":memory:");
// Create tables
sql = "create table Table1 (col1 varchar(32), col2 int);"
"create table Table2 (col1 varchar(32), col2 varchar(64));"
"create table Table3 (col1 varchar(32), col2 int);"
"create table Table4 (col1 varchar(64), col2 int, col3 smallint, col4 int, col5 DateTime);"
"create table Table5 (col1 varchar(64), col2 varchar(64), col3 varchar(1024));";
exec_sql(db, sql);
// Do insert operations
sql = "insert into Table1 values ('xxxxxxxxxxxxxx', '523620105');insert into Table2 values ('xxxxxxxxxxxxxx', 'xxxxxxxxxxxxxx');insert into Table3 values ('xxxxxxxxxxxxxx', '1688709171');insert into Table4 values ('xxxxxxxxxxxxxx', '844867696', '32671917', '424084999', 'xxxxxxxxxxxxxx');insert into Table5 values ('xxxxxxxxxxxxxx', 'xxxxxxxxxxxxxx', 'xxxxxxxxxxxxxx');insert into Table1 values ('xxxxxxxxxxxxxx', '0');insert into Table2 values ('xxxxxxxxxxxxxx', '0');insert into Table3 values ('xxxxxxxxxxxxxx', '0');insert into Table4 values ('xxxxxxxxxxxxxx', '0', '0', '0', 'xxxxxxxxxxxxxx');insert into Table5 values ('xxxxxxxxxxxxxx', 'xxxxxxxxxxxxxx', '0');";
for (i = 0; i < 20000; ++i)
if (i % 1000 == 0) printf("%d\n", i);
exec_sql(db, sql);
// Clean up
cleanup(db);
int
main()
db_handle *db;
testMemoryDatabase();
testMemoryDatabase();
testMemoryDatabase();
testMemoryDatabase();
// Add more testMemoryDatabase() calls...
The out of memory error somewhat blocks us to use BDB memory DB...if it can be solved that will be great. Also, please point out right place if the forum is not the place to report such a bug.
Thanks a lot!
- lieHi Lie,
I have reproduced the issue and we're investigating a fix that will be available in a future release. If you need a solution sooner than that, please let me know.
Thanks again for the report.

Running out of memory despite having set je.maxMemory to a moderate value
I have set je.maxMemory to 20MB (je.maxMemory=20000000) and allowed a max heap size of 512MB (-Xms256M -Xmx512M).
After two hours of running my web service, I'm running out of memory. After having profiled my service (using Yourkit Java Profiler 1.10.6), I can see the following:

In any case, com.sleepycat.je.tree.BIN claims ~ 116MB of heap memory, which is by any goodwill, exceeded the limit of 20MB.
How can this be?
How is JE ensuring that the limit is not exceeded? Is there a timer (thread) running which once a while checks the memory used and then cleans up ; or is memory usage checked creating a com.sleepycat.je.tree.BIN object?

I'm not sure whether the profiler is reporting live objects only (referenced) or all objects (including those not yet reclaimed). If the latter, it isn't telling you how much memory is actually referenced by the JE cache.
Please look at the JE stats to see what the cache usage is, from JE's point of view.
If you believe there is a bug in JE cache management, you'll need to write a small standalone test to demonstrate it and submit it to us, since we don't know of any such bug. Also note that we'll have difficulty supporting JE 4.0 (without a support contract anyway). Please use JE 5.0, or at least 4.1.
Eviction occurs as objects are allocated, as well as in background threads. Eviction in background threads and concurrent eviction were greatly improved in JE 4.1.

Out of memory problem using the API
Hi all,
I need your assistance, we are working with CDB 10.2 making searches and retrieving the documents with all their attributes.
In our actual scenario we have a single user (which represents an application) accessing CDB. This user use several persistent sessions simultaneously. I mean, several thousands of final users connect to an application that uses one user of CDB to connect to CDB with several persistent sessions.
To simulate this scenario we wrote java code that open five threads and make several searches (requesting all the attributes) using the same user on cdb.
Retrieving a considerable amount of data found on the search (~5000), we found a “Out of memory” problem when we made these tests:
- 5 threads obtaining 100 documents (and all their attributes) / search
- 1 thread obtaining 500 documents (and all their attributes) / search
- Also we have same problem if we make several searches with less results
We suppose it’s a configuration or code issue so we ask for your assistance and experience to solve it.
Thanks for your help,
Dani

Java Out of memory error when accessing MySQL
Hi all
I've got a weird problem, I programed some code to mirror data between two databases and I was testing it with two different computers each one running MySQL. The first database has 33,000 rows across 40 columns and the second one 380,000 rows across 40 columns. When trying to transfer the data from the small database to the large one everything works fine, after a couple of minutes all 33,000 rows are successfully transfered to the large one.
But then I tried it the other way around, transfer 380,000 rows to the small. This does not run at all it just gives me an error of Out Of Memory and stops. I tried on win2k, winxp and redhat 7.3 same error. Does anyone has any idea why this is happening? All three machines have 512MB RAM.
Is there a limit on the size that a result set can have? I really need to know since this database is gonna grow by aprox. 136,000 rows per hour or 3,264,000 rows per data. That's about 3 GB of data per day which needs to be mirrored across the databases.
Any suggestions would really be apreciatedThanks for the response guys,
The purpose of this program is to mirror the data between two databases. The first one sits on a machine that is monitoring a system through sensors connected via a DSP card. Now the processing of the gathered data is done on the second machine. This mirroring needs to happen every day and as I said on my previous post the amount of data is aprox. 3GB per day or about 1.2m rows per day. I know this is a huge amount of data.
In the program I've written what I do is:
get a connection to both databases on both servers then I create a prepared statement to do the INSERT. Then I get a result set from the first database and in the while loop I update the data to the second one. So only one result set is used. Now I shouild let you know that there's never gonna be any updating of the data only new ones get added.
I am assuming by the error I get that when I get my result set it tries to load it all in memory which I do not want to do for the obvious reasons.
I am including my code

nullHi,
Here is the problem. As per your suggestion I had installed
Jdk1.8.8 and jdbc driver too. Though I am having one JDBC driver
in oracle8i, I have downloaded from your site and set the env
path and run the env.bat file. Then when I tried to execute the
Java OracleXML getXML -user "scott/tiger" "select * from emp"
file I got runtime error. But first time what I did was I had
already run the oraclexmlsqlload file so there are lot of
chances for OracleXML class file to be deleted. So Again I ran
the oraclexmlsqlload bat file, so definitely it should load the
oraclexmlsql file and xmlparser file. I didn't get any error. So
I tried the file for xmlgenpkg it says package created with no
errors and when I tried the oraclexmlsqltest file I got the same
error...what I did get yesterday............
Here is the output , please help me out....

Greetings:
I am working on how to use xml and 8i to our benefit. I have
installed Oracle 8i and I have downloaded the XML SQL Utility.
In checking out the installation using the standard "java ...
select from" example I get the following error:
Exception in thread "main" java.lang.NoClassDefFoundError:
OracleXML
The first place I checked was the env.bat file, I found an
incorrect classpath and changed it:
rem - JDK_HOME
set JDK_HOME=C:\JDK1.1.6 (no such folder)
to
rem - JDK_HOME
set JDK_HOME=C:\JDK1.2.2
All other paths look good. I executed the bat file and tried the
example again. Same error.
Any Ideas??
nullStill same error.
Here is what I've done.
1. rem the JDK Home
2. downloaded Java 1.1.8 JDK
3. changed computer env. path to include 1.1.8 JDK
I have checked all the paths in the bat file and all are pointing
to the correct place to find the file listed with one exception:
I don't have a src file in the %PD% folder.
rem This need not be changed
set
XMLSQL_DIR=%PD%\lib\oraclexmlsql.jar;%PD%;%PD%\src;%PD%\lib;%PD%\
sample
Where should it be pointing for the src file?

My analysis is that hashtable is causing this issue.
In my application I am using hashmap to store resultset objects and use request.setAttribute("databasevaluesforuser", databasevalues) to show in jsp.
Could it be that after the values are displayed the hashmap still contains those objects and when multiple users
access the application, heap size increases and this causes out of memory issues. I also paginated some jsp so that users view part by part of the results from database and thus prevent memory outage.
Could anybody help me in this issue. Please inform me if I need to provide any further information.Aplogies for answering late.
I am using SUN 1.4 jvm
The analysis of GC logs showed that lot of memory is consumed by java hashmap. In my application I am using hash map only to store the results from database and then represent at jsp using the request parameter.
