Too many archive file generated

Hi there,
I'm doing a load test that insert 12 meg data into a test table. Nobody is on the database except me. My online redo log size 200 meg. Why did the database did two log switches when on 12 meg data inserted to the database? My database version is 10.2.0.2.
thanks

A typical redo record has a minimum size of around 200 bytes. Before you worry about the data it contains, remember it has to hold details about the block being changed and the undo block being used to hold the undo for that change and various pointers and other bits of structural information. You then have two redo records per row inserted - one for the table change and one for the index changed. 2 * 200 * 1000000 gives you about 400Mb, which fits your observation of two log file switches with 200Mb log files.

Too many trace files generated by program ORACLE.EXE (J001) in "bdump"

Hi,
Please help!
the following trace file messages have been created in my "bdump" folder about every 6 minutes, so it generates about 200 files per hours. Can someone tell me how to solve the error or stop the trace files be generated. Thanks.

No version number and not enough information in what you posted to help you.
Did this just start?
If so what actions preceded it?
Or is this a new install?
Have you tried bouncing the instance?
If it were my system I would have already searched the knowledgebase at metalink and opened an SR if I couldn't find a solution. Did you?

Apps team uploading 114505 kbof text file,too many archives getting

the upload is going on ,too many are getting generated in archivelog location
i have increased 200gb to 900gb
please let me know how to know for 14505 kb of dataupload how many archives gettting generated
can we estimate before dataupload how many archives can generate
can you please explain clearly
thanks

Hi,
There is no specific method to calculate the number of archived log files to be generated for the particular load.
But, we may do some rough calculation by looking at the rate of archived log generation.
Check the following things,
1) How frequently the logs are getting generated and the size of the files.
2) How many data has been loaded so far.
Based on the above input, you may get some idea on number of ARCHIVED LOG files to be generated during the rest of the data load.
Also, you may do the following to avoid keep adding space to archive destination.
1) Wite a UNIX shell script to BACKUP the ARCHIVED LOG FILES and DELETE the files once backuped up; which should run for every 10 minutes.
Thanks.

Create procedure is generating too many archive logs

Hi
The following procedure was run on one of our databases and it hung since there were too many archive logs being generated.
What would be the answer? The db must remain in archivelog mode.
I understand the nologging concept, but as I know this applies to creating tables, views, indexes and tablespaces. This script is creating procedure.

The amount of redo generated is a direct function of how much data is changing. If you insert 'x' number of rows, you are going to generate 'y' mbytes of redo. If your procedure is destined to insert 1000 rows, then it is destined to create a certain amount of redo. Period.
I would question the <i>performance</i> of the procedure shown ... using a cursor loop with a commit after every row is going to be a slug on performance but that doesn't change the fact 'x' inserts will always generate 'y' redo.

I do not recommend reformatting your harddrive and reloading your software. This is a Windows thing. On an older mac it may be difficult to find all your software again.
Best to have greater than 2gig of free space. Many posters to these forums state that you need much more free space: 5 gig to 10 gig or 10 percent of you hd size.

Be careful when deleting files. A lot of people have trashed their system when deleting things. Place things in trash. Reboot & run your applications. Empty trash.
Go after large files that you have created & know what they are. Do not delete small files that are in a folder you do not know what the folder is for. Anything that is less than a megabyte is a small file these days.

Intermittent too many open files error and Invalid TLV error

Post Author: jam2008
CA Forum: General
I'm writing this up in the hopes of saving someone else a couple of days of hair-pulling...
Environment: Crystal Reports XI Enterprise / also runtime via Accpac ERP 5.4
Invalid TLV error in Accpac
"too many open files" error in event.log file
Situation:
Invalid TLV error occurs seemingly randomly on report created in CR Professional 11. Several days of troubleshooting finally lead to the following diagnosis:
This error occurs in a report that contains MORE THAN 1 bitmap image.
The error only shows up after 20 or more reports have been generated sequentially, WITHOUT CLOSING the application that is calling the report. In our case the Invoice Report dialog within Accpac. This same error occurred in a custom 3rd party VB.NET app that also called the report through an Accpac API.

after getting this message you need to do 2 things:
1. delete the current workspace because it contains some bad data in one the config files - failure to delete the workspace will result the error message to appear even if trying to upload a single file.
2. add to DTR files in groups - no more than 500 in a single add.

Actually, the stuff works in interpreted mode.
It's only when having the server partition compiled that this happen.

Hi Jean-Paul,
As described in the Technote 10981 some Forte programs (Nodemanager and

that Forte interpreter do it correct too.

Hello Marco.
When you try to deploy an EAR weblogic server at the time of deployment unjar's it and compiles the files and so on. Every Operating system has a limit on how many number of files can be opened by a process. If your EAR is big then the number of files which WLS will unjar will also be large hence you hit the limit. By splitting your ear into 2, you are splitting wls task into smaller parts, which means the number of files it unjars at a time is less.
The following note tells what needs to be done to avert this issue.

Too many Archive Log

Hi,
I have a problem on a production server: our support partner told me that we are creating too many Archive Log files. They are not sure at all of what is happening.
Please, do you know if there is any System View which we could obtain more information about Archive Logs usage?
Thanks in advance.
Best Regards,
Joan Padilla

Hi Joan,
The sensible number of archive logs is determined by your backup and recovery strategy. You can delete them, once you have back-upped the database and the archivelogs. Further info in the Backup and Recovery Concepts manual.
You can find information on them in v$archived_log.
If you decide to delete them without having read the aforementioned manual, I will pray for you you don't suffer a hard disk crash.
You may want to review the relationship with your support partner too.
Their advice is not exactly professional.

System I/O and Too Many Archive Logs

Hi all,
This is frustrating me. Our production database began to produce too many archived redo logs instantly --again. This happened before; two months ago our database was producing too many archive logs; just then we began get async i/o errors, we consulted a DBA and he restarted the database server telling us that it was caused by the system(???).
But after this restart the amount of archive logs decreased drastically. I was deleting the logs by hand(350 gb DB 300 gb arch area) and after this the archive logs never exceeded 10% of the 300gb archive area. Right now the logs are increasing 1%(3 GB) per 7-8 mins which is too many.
I checked from Enterprise Manager, System I/O graph is continous and the details show processes like ARC0, ARC1, LGWR(log file sequential read, db file parallel write are the most active ones) . Also Phsycal Reads are very inconsistent and can exceed 30000 KB at times. Undo tablespace is full nearly all of the time causing ORA-01555.
The above symptoms have all began today. The database is closed at 3:00 am to take offline backup and opened at 6:00 am everyday.
Nothing has changed on the database(9.2.0.8), applications(11.5.10.2) or OS(AIX 5.3).
What is the reason of this most senseless behaviour? Please help me.
Thanks in advance.
Regards.
Burak

Selam Burak,
High number of archive logs are being created because you may have massive redo creation on your database. Do you have an application that updates, deletes or inserts into any kind of table?
What is written in the alert.log file?
Do you have the undo tablespace with the guarentee retention option btw?
Have you ever checked the log file switch sequency map?
Please use below SQL to detirme the switch frequency;

Java.io.IOException: Too many open files while deploying in soa 11g

hi all,
I am getting a strange error while deploying any composite .. it's a hello world kinda composite but while i am trying to deploy it i am getting "java.io.IOException: Too many open files" while deployment.. i have tried to deploy it in 2-3 ways but all of them resulted in the same error..bouncing the soa server might be an option but can someone give an insight as why it is happening and can it be resolved without restarting the server..
Thanks

yes..so this problem is with unix only ..coz i previously worked in Windows ..never got this problem..

But this problem is understandable, as the database is not running. The main problem why database is not running, I have found the reason but do not understand how to solve the problem.
Since, the database was not running, I tried to startup the database, I then came across the following which is my problem (Why so many files are open? Linux OS error says too many files open. See below,
SQL> conn /as sysdba
Connected to an idle instance.
SQL> startup
ORACLE instance started.

ORA-27041: unable to open file

Can anybody has run into such problem and guide me to a solution, please?
Thanks

Hi,
yes, this DB was functioning o.k. this configuration script was part of RMAN daily backup.
Last night the backup failed. So, when I opened "Failed job" in the EM, I saw this type of messages.
That was the starting point. Gradually, I tried to narrow down on to the actual problem and found the findings as I have posted.
One way of sovling problem, I thought that, all these processes I would kill and then try to open the database, it might startup. However, that wouldnot lead me in ensuring this won't occur again.
That's why I am trying to understand why it should open, so many processes (why spawn so many .flb files?) Any thoughts you have around this?
I will try to restart the OS as the last resort.
Thanks for your help and suggestions.
Regards,

"java.io.IOException: Too many open files" in LinuX

Hi Developers,
* I am continiously running and processing more than 2000 XML files by using SAX and DOM.....
* My process is as follows,
- Converting the XML file as Document object by DOM....
- And that DOM will be used while creating log file report, that log file will be created after executing all XML files..
* After processing approx 1000 files, it throws *"java.io.IOException: Too many open files" in LinuX system* ....
* I have googled more and more in all sites including sun forum also, but they are telling only to increase the system config by ULIMIT in linux....If i increase that its executing well without exception........
* My question is, Is it possible to do it by JAVA code itself or any other VM arguments like -Xms512m and -Xmx512m.....
* Please let me know , if you have any idea.....
Thanks And Regards,
JavaImran

Doh! I forgot to post my little code sample...
package forums.crap;
import java.io.*;
import java.util.*;
public class TooManyFileHandles
private static final int HOW_MANY = 8*1024;
public static void main(String[] args) {
    List<PrintWriter> writers = new ArrayList<PrintWriter>(HOW_MANY);
    try {
      try {
        for (int i=1; i<=HOW_MANY; i++ ) {
          writers.add(new PrintWriter("file"+i+".txt"));
      } finally {
        for (PrintWriter w : writers) {
          if(w!=null)w.close();
    } catch (Exception e) {
      e.printStackTrace();
}... and the problem still isn't OOME ;-)
Cheers. Keith.

WLS 10.3.5 on RHEL 5.4, SocketException: Too many open files

Hi
I'm running Weblogic server 10.3.5 on Red Hat Enterprise Linux Server release 5.4 (Tikanga), with Java jdk1.6.0_27.
My order handling application, when receiving client orders, needs to make outbound SOAP calls to fulfill the order. During a performance test, we got following errors:
####<Feb 10, 2012 2:28:41 PM ICT> <Critical> <Server> <KKMOMAPP2> <KKMOMPE2> <DynamicListenThread[Default]> <<WLS Kernel>> <> <> <1328858921806> <BEA-002616> <Failed to listen on channel "Default" on 172.24.106.81:4095, failure count: 1, failing for 0 seconds, java.net.SocketException: Too many open files>
I monitored the java process of this application, when the "Too many open files" error happened, it had 1388 open file descriptors, among which 655 were sockets.
I also monitored the total open file descriptors of the weblogic user account, the count was around 6300 during this error.
These numbers are far smaller than the file limits configured on OS:
- Under weblogic account, ulimit -n shows 65536
- /proc/sys/fs/file-max shows 772591
- Following lines are already in /etc/security/limits.conf
weblogic soft nofile 65536
weblogic hard nofile 65536
weblogic soft nproc 16384
weblogic hard nproc 16384
I did another test using a simple java program to open large number of sockets under weblogic account. It has no problem to open 15,000 sockets. It seems the file descriptor limit is indeed quite high, but for some reasons, the Weblogic process fails even when it has merely 1388 open files. Are there other Linux or Weblogic parameters I should tune? Or anything else I missed?
Thank you very much
Ning
