Blob causes java.lang.outofmemory

Hi Guys,
Not sure whether this has to do with lazy initializing or not,
but here's the situation.
I have got a files table and files_content is a blob holding the file as binary object,
when ever I fetch the set, and try to display it by name, the blob object is loaded also,
since some files contain more than 8 MB it causes a java.lang.out of memory exception.
How do I prevent the blob attribute from loading in memory? I just want to load it when the file is clicked and it is time to send the file to the user, either inline or as dowload.....
Hope I make sense.
All the best,

Increasing heap memory size may not solve all kinds of OutOfMemory errors. There may be leaks in your Java code or third-party code or there may be native leaks (translated and reported as OutOfMemoryError). You may want to try Java SE 6 (http://mustang.dev.java.net). Java SE 6 prints descriptive message with OutOfMemoryError and attempts to print stack trace with OOM (http://blogs.sun.com/roller/page/alanb?entry=outofmemoryerror_looks_a_bit_better)

Java.lang.OutOfMemory error while retrieving data from a large table

Hi,
i am trying to fetch data using "executeQuery()" into a ResultSet from the database. But since the data in that table is large. i am recieving "java.lang.OutOfMemory" Error. So, to resolve that, i have used "setMaxRows()" for my statement object. This resolved the error but i don't recieve the entire data. If i call "executeQuery()" again, i recieve the same data. I don't even know a filtering criterion where by i can filter the data for each "executeQuery()"..
How can i resolve this problem
Thanx in advance
--Chaitanya

Either use some criteria you develop related to one of the keys on the table or use some sort of record limiting method.
Note the method of limiting will vary related to the database you are using. You will have to look at the documentation.
For example I am told this will work in MySQL to get 200 records starting at record 100.
SELECT * FROM myTable ORDER BY whatever ASC LIMIT 100,200
Because you are running out of memroy I assume the table is large,
I am not sure what the impact of the above will have on performance because if in the above if the order by is not based on an index at the server level all the records will be selected and sorted before the records are limited.
I would make sure you have an appropriate index.
If you use the advanced search over the user forums using "resultset paging" and possibility the database you are using you should be able to get some ideas.
I hope this makes sense to you.

A working application suddenly caused java.lang.NoClassDefFoundError

I have a web application running on a resin server. Everything in my application worked fine at the beginning but suddenly I got java.lang.NoClassDefFoundError. I looked at the line number of the exception and found out that the classes causing java.lang.NoClassDefFoundError are always the ones that contain static collection of data. The samples of those classes are CityList class and CountryList class which has a HashMap of city IDs and the city name strings. I'm not sure why those classes suddenly become unavailable. The strange thing is that my application becomes normal again when I upload my classes to site. Please note that my webhoster set up the server so that every time I upload my file to their given directory, it's automatically copied to the resin server. I have no direct access to the resin server myself. After I re-upload my classes, everything seems ok for a few hours, then suddenly I get NoClassDefFoundError again.
Anyone knows why? Please help. I have no idea why this is happening.

I seem to have a similar problem. No fix...looking for a solution.
I have a stand alone java application that will run for a long period of time. While running it calls a specific static method on a class. Everything is working fine (while executing the method in the class) and then, all of a sudden, I will get a noClassDef error.
I am running this application with a number of JVMs, all using the same version of Java and they do not show this problem. I know that they are all calling the same class and method and they never have the problem. But, every now and then, it seems like there is some runtime condition that comes up where it is not able to load a class.
The problem appears to be dynamic because I can restart the application (after the JVM crashes with the exception) and everything works fine, including the class and method that caused the problem. I start everything with scripts so there is no variation in classpath settings.
I have seen a similar problem in a non-static class when one event happens and it goes to load a common class (that I know is in the classpath) and I get the noClassDef error.
Could this be a threading issue in any way? No ideas, no fixes in sight. Any ideas or questions would be helpful.

Unable to read big files into string object and java.lang.OutOfMemory Prob

Hi All,
I have an application that uses applet and servlet communication. On the client side I am reading an large xml file of 12MB size (using JFileChooser) and converting the file to an string object using below code. But I am getting java.lang.OutOfMemory on the client side . But the same below code works fine for small xml files which are less than 4MB sizes:
BufferedReader in = new BufferedReader(new InputStreamReader(new FileInputStream(file),"UTF8"), 1024*12);
String s, s2 = new String();
while((s = in.readLine())!= null)
     s2 += s + "\n";
I even tried below code but still java.lang.OutOfMemory is coming:
while (true)
     int i = in.read();
     if (i == -1)
          break;
     sb.append(i);
Please let me know what am I doing wrong here ...
Thanks & Regards,
Sony.

Using a String is bad for the following reason:
When you initially create the String, it has a certain memory size (allocated length if you will). As you keep appending to this String, then memory reallocation will occur over and over, slowing your program down dramatically (ive seen with a 16k x 8 Char file taking 30 secs to read into memory using Strings in this way)
A Better way would be if you knew the number of characters in the XML file (Using some File size method for example) Then you can use a StringBuffer, which will pre allocate enough space (or try to, it may just be that you cannot create a string as large as you need). You can use toString() method to get the resultant in a String Object (the extra allocated space at the end of the Buffer will be removed)
StringBuffer strBuf = new StringBuffer(xxxx);
Where xx is the length (int). Assuming that you are only allowed to enter an int to the constructor then (platform depedant) an int is 2^31 at maximum (or whatever) which allows 2.14e9 characters, therefore an xml file being totally filed would allow a size of ~2048 MB to be read in.
Try it and see.

Hi,
I could avoid the java.lang.OutOfMemory error using below code. But using below code I could read small files of sizes less than 4MB
but with large files of 12 MB the below code just simply hangs and I am unable to print the string object namely 's'.
My purpose is to construct an String or StringBuffer object out the user uploaded xml file at the client side and pass that object to server for processing. So how can I construct such object avoid memory problem and increasing the performance of such operations.
BufferedInputStream in = new BufferedInputStream(new FileInputStream(file));
byte[] b = new byte[in.available()];
in.read(b, 0, b.length);
String s = new String(b, 0, b.length);
in.close();
Thanks & Regards,

Why do I get a java.lang.OutOfMemory exception

Thanks, in advance, for you help.
I just wrote a fairly large program. Every time I run it, I get a java.lang.OutOfMemory exception. I have no idea how to debug my code. Why would I get such an exception and how would I debug it?

put more debug statements
and see which line its giving that exception and see whether some where u have any line which is kind of looping or memory allocation .
As i havent seen ur code thats vague idea iam giving
java.lang.OutOfMemory exception is Thrown when the JVM cannot allocate an object because it is out of memory, and no more memory could be made available by the garbage collector.
hope this might help

Sun identity manager - java.lang.OutOfMemory

Hi, I have one very interesting issue regarding JVM memory. I have one sun idm (version 7) application deployed in sun java web application server. I am facing JVM error - java.lang.OutOfMemory very frequently now days in production server. I am sharing you the details regarding configuration :
Their are 4 app servers - IDMAPP01 IDMAPP02 IDMAPP03 IDMAPP04
current total memory on each of the 4 app server 8 GB
memory allocated to JVM on each server 5 GB
os - solaris
admin task recon are performed only on instance - IDMAPP04
JVM setting is - -Xmx5g -Xms5g -Xmn1500m -XX:MaxPermSize=512m
Log file locations:
/var/opt/SUNWappserver/domain1/logs/vm.log
/var/opt/SUNWappserver/domain1/logs/gc.log
/opt/SUNWappserver/appserver/config/asadminenv.conf
/opt/SUNWappserver/appserver/config/asenv.conf
idm app deployment path:
/var/opt/SUNWappserver/domain1/applications/j2ee-modules/idm
logpath
/var/opt/SUNWappserver/domain1/logs/
Whenever I am getting this issue, we are restarting all the 4 server instances which is impacting business as this is prod server.
Can anyone suggest how can I solve this issue. (please suggest good performance tuning tips without increasing physical memory).
Regards,
Jimmy

Whenever I am getting this issue, we are restarting all the 4 server instances which is impacting business as this is prod server.Why? The whole idea behind running recon on a separate server is that you can restart that one without affecting the others.
Can anyone suggest how can I solve this issue. (please suggest good performance tuning tips without increasing physical memory).
Enable gc logging and use a profiler to capture the behaviour of the jvm. You need to understand what it is doing and find where the problem area is before you can recommend what to tune.

Cannot start OC4J instance - after java.lang.OutOfMemory errors

Hi, I have successfully deployed an application (using Oracle Web Services, J2EE - EJB, TopLink ) to a new OC4J instance that we created. We use the OEM web site to manage the start/stop and deploy operations.
Then we tried to run simultaneously 10 clients....against the server app... ran ok for a while and after approx. 5 to 10 min... java.lang.OutOfMemory errors were being thrown at the client.
After a set of OutOfMemory errors, other clients received errors like the ones show below:

Im not sure if this is due to a memory leak or something in my app ? Or does Oracle IAS / Toplink have any such issues for which any possible patches are available ?
Could anyone please direct me in the possible right direction !
Thanks,

Hi,
We have had this problem too, it only started after we deployed to production and got some load on our application server. We are using JRun as our application server.
We found that Macromedia (JRun) already addressed the issue in general - that if you get java.lang.OutOfMemory errors, then you need to increase the heap size.
Previously we had been using our own caching mechanism and never ran into this problem. Since we decided to go with TopLink (which has caching) we no longer use our own caching mechanism... but now we have this problem.
We have chosen to use FullIdentityMap for caching, but didn't think we would run out of memory in the JVM. Is there a suggested or minimum JVM memory requirement to run TopLink?
Thanks,
Aaron

Java.lang outofmemory exception in IR

Hi
We are on XI 3.0 SP13 and involved in creating a message mapping. We have a big XCBL PO structure as the target - and while we do the mapping effort, every now and then, we get a java.lang outofmemory exception ( display error ) when we save the mapping.
I notice that my CPU util is 100% and is taken up by javaw.exe. I have a 1.6 G RAM desktop - but still face this problem. Any suggestions as to how to overcome this memory problem ? Am I missing any setting in my desktop ?? Or do we have to live with this problem since the target structure is a generic/big structure ??
Thank you in advance for your time.

Hi
actually, this problem has nothing to do with the server at all. Also paging size and your desktop ram do not really matter. By default IB starts with the parameter -Xmx512M, what means that Java gets maximum 512M of RAM. You can change it saving JNLP file to your local file system and changing there this argument to -Xmx 800M or -Xmx 1024M.
The second way is to reduce schema sizes. Usually there are a lot of "annotation" and "documentation" tags. They can be easily removed withoud damaging the mapping(the only problem that in design time you'll not see a documentation for fields). If you want to go this way, you can tell me and I'll find out how it can be done by some tool. Because we had this problem with other customers and as I remember there were some tool made for this purpose.
Although it might help to install the latest SP, because there were made a number of changes to reduce a memory consumption for Message Mapping tool
Best regards
Dmitry

Blob and java.lang.AbstractMethodError

I can't make this code (below) to work. I get an java.lang.AbstractMethodError trying. Does anyone have a clue about what might cause this error?
My setup:
jsdk 1.4
Oracle 8.1.7
Forte4J 4.0
Thanks in advance
Roland
---------- the code --------------
conn = cp.getConnection(_database, user, password);
conn.setAutoCommit(true);
PreparedStatement stat = conn.prepareStatement(sql.toString());
stat = conn.prepareStatement(sql.toString());
stat.setLong(1, id);
ResultSet res = stat.executeQuery();
if(res.next()){
setId(res.getLong("id"));
Blob b = res.getBlob("data");
stat.close();

PreparedStatement stat =
conn.prepareStatement(sql.toString());
stat = conn.prepareStatement(sql.toString());yes there is something wrong there but if your problem is
occurring with
Blob b = res.getBlob("data");then the problem is that the ResultSet you are using does not implement this method. getBlob is a method that was introduced in JDBC 2.0. in fact the Blob interface itself was introduced in JDBC 2.0.
you can try on of the following...
get a new driver that implements getBlob. for oracle i think you will be fine. you can get a new driver here http://otn.oracle.com/software/tech/java/sqlj_jdbc/content.html
the other option if you cannot get a new driver is to use the getBinaryStream() method of ResultSet to retrieve your data

Addition of fields in ABAP RFC causes java.lang.ArrayIndexOutOfBoundsExcept

Hi,
I had been calling an ABAP RFC from my WDJ application successfully till yesterday. Then we felt the need for 2 additional fields in RFC for better results. Since then, I'm not able to call this RFC. The error being thrown is copied below.
All context mappings are done correctly and there is no compilation/build error in application but on runtime the following error is being thrown.
Can someone guide me here for solution to this issue?
Thanks,
Vishwas.

Hi Vishwas,
                   After changing the RFC , u need to reimport the model & server has to be restarted for refreshing the model.if that u have already done, send the code.

Date(mysql) - date(oracle 8i), java.lang.OutOfMemory

PLATFORM AND O/S VERSION: RedHat Linux 7.2, Kernel 2.4.9-21smp, Oracle 8.1.7.4
MIGRATION WORKBENCH VERSION: 9.2.0.1.2 (Windows 2000, ServicePack 2)
THIRD-PARTY DATABASE AND VERSION BEING MIGRATED: MySQL 3.23.41
Hi there,
I urgently need to migrate a mysql (3.23.41) database (7.1 GB) into Oracle 8i (8-1-7-4),
but faced a lot of problems during migration.(capturing went well):
1. ORA-01843: not a valid month
2. java.lang.OutOfMemoryError
For error no. 1:
Here comes a description of a suspicious source table(mysql), which has a 'datetime' (column: 'created')
in it:

I tried to map the 'date' datatype from mysql into the date datatype in oracle, but always
got the ora-01843 error.- How can I EXACTLY set 'NLS_DATE_FORMAT'/'NLS_DATE_LANGUAGE' to fit?
Or is there any other solution? (NLS_LANGUAGE is being initialized as 'AMERICAN')
For error no. 2:
I tried using Java 1.3.1 (which comes with omwb) and java 1.4.0_02.
RAM(on notebook running OMWB ): 256 MB; javaw -mx1024m.
Virtual Memory on machine running OMWB: 1024 MB.
Unfortunately, there was now success. What else can I do?
Is there any possibility to have a look at the generated sql (inserts etc.)
during migration?
Your help is highly appreciated. Thanks for your effort in advance.
Best Regards,
Dan
P.S.: I also tried to use Oracle 9i with 'date' to 'timestamp' mapping, but also got 'ora-01843'
error and additionaly:
'Failed to create default for Table :HOMO_SAPIENS_CORE_8_30.ANALYSISPROCESS; ORA-00907: missing right parenthesis'

Hi Dan,
For Error 1:
This is unusual behaviour. I will raise a bug against the product to have it investigated further but I have not encountered this before. To workaround
the problem, you can firstly migrate the database schema (without the data) by choosing the 'No' radio button in 'Step 3 of 4: Migrate Table data' in the
Migration Wizard. When the schema has successfully been migrated you can create SQL*Loader scripts for the table(s) you want to
migrate data for by select the table name in the Oracle Model UI in the Migration Workbench and choosing Object-Generate SQL*Loader Scripts from
the menu bar. To find out more about the offline data loading facility in the Migration Workbench please refer to the MySQL plugin reference guide.Note that
in the 'sql_load_script.bat' (which is one of the files generated by the Object-Generate SQL*Loader Scripts menu command, you can set your specific
requirements for NLS_DATE_FORMAT, NLS_TIMESTAMP, NLS_LANGUAGE etc.I think this will get you over the problem you are encountering at the
moment.
For Error 2:
Could you provide me with the error.log file that exists in your OMWB\Log directory please ? This may contain extra information about the cause of this
problem. Your virtual memory size etc. should be more than adequate. Also, is this problem happening at a particular point in the migration that you can
identify - e.g. on a particular table ? If so, perhaps you could provide me with the datails of the column types of this table, the number of rows of data
it contains etc. In the meantime, the solution to error 1 may actually be a workaround fot this problem too.
If you need any additional information on the above points, please don't hesitate to contact me.
Tom.
