Berkeley db fatal region error detected run recovery

Hi,
I have initiated d Berkeley DB object.
Then, I am using multithreading to put data into the DB.
Here is how I open the one data handler.
ret = dbp->open(dbp, /* Pointer to the database */
NULL, /* Txn pointer */
db_file_name, /* File name */
db_logical_name , /* Logical db name (unneeded) */
DB_BTREE, /* Database type (using btree) */
DB_CREATE, /* Open flags */
0644); /* File mode. Using defaults */
each threads would put data into the same handler when it needs to.
I am getting "berkeley db fatal region error detected run recovery".
What is the problem? Does it have anything to do with the way the handler is created or whether multiple threads can put data into the DB?

I am getting "berkeley db fatal region error detected run recovery".This is a generic Berkeley DB panic message that means something went wrong. When do you get this error? Did you enable the verbose error messages? Are there any other warning/error messages reported? By just posting the way you open the database doesn't help much at all. I reviewed the other questions you asked on the forum, and it seems that you are not following the advices and consult the documentation, but you prefer to open new threads. I advice you to first work on configuring Berkeley DB for your needs and read the following pages in order to understand which Berkeley DB Product best suits your application and how it should be configured for a multithreaded application:
[The Berkeley DB products|http://www.oracle.com/technology/documentation/berkeley-db/db/ref/intro/products.html]
[Concurrent Data Store introduction|http://www.oracle.com/technology/documentation/berkeley-db/db/ref/cam/intro.html]
[Multithreaded applications|http://www.oracle.com/technology/documentation/berkeley-db/db/ref/program/mt.html]
[Berkeley DB handles|http://www.oracle.com/technology/documentation/berkeley-db/db/ref/program/scope.html]
On the other hand, if the code that's calling the Berkeley DB APIs is not too big and is not private, you can post it here so we can review it for you and let you know what's wrong with it.
The procedures you should follow in order to fix a "run recovery" error are described here:
[Recovery procedures|http://www.oracle.com/technology/documentation/berkeley-db/db/ref/transapp/recovery.html]

Db_verify: PANIC: fatal region error detected; run recovery

We have an application that is using bdb. On one of the instances it frequently hits a panic condition. db_verify reports the following:
# db_verify -o file.db
db_verify: PANIC: fatal region error detected; run recovery
db_verify -VSleepycat Software: Berkeley DB 4.3.29: (June 16, 2006)
Quitting the application and removing the __db.001 file will allow a clean restart. How do I debug where this problem might be coming from?

You will need to know about recovery. I suggest you read up on it in the Berkeley DB reference guide:

Fatal region error detected; run Recovery

I try include 2600 documents 1,06 GB and I have the message (Fatal region error detected; run Recovery ). I executed db_recover.exe to try resolve the problem without sucess. I did this test in 3 differents computers and I had the same problem. I am use a free version , I am studyng berkeley db xml and need test performance with a big collection of document xml. Why am I have problem if berkeley db xml is able to support terabyte in size.

This message indicates that you are probably setting your Berkeley DB cache size too large. MapViewOfFile is the Windows API used to map the cache file. It will fail if Windows cannot find enough contiguous VM for the mapping.
Regards,
George
I have about 30 documents ~10MB and I get this all
the time.
MapViewOfFile: Not enough storage is available to
process this command.

I've set this up on a Window XP machine using tomcat 5.5 and java 5 as well as a Redhat Linux machine with tomcat 5.5 and java 5. I'm using the Web Service point for other servers to access the database. Everything starts up and runs for a little while, but I can't seem to pin down what causes the errors. I've run recovery multiple times as well as started new databases. Any help is appreciated.

There's a bug in your use of DB XML somewhere. Are you committing or aborting every transaction that you start, and calling delete() explicitly on all the DB XML objects that you use?
Those errors mean your database has become corrupted somehow.

Problem sqlite+berkeley PANIC: fatal region error detected.

Excuse for my English and if this wrong place to explain the problem
I'm checking to replace Berkeley DB and SQLite for testing the stability against involuntary interruptions of program I have encountered the following error:
Berkeley DB trust in knowing his rnedimiento and stability with Subversion, but I doubt the API bridge SQLITE
I'm testing the Berkeley DB database using the API Berkeley DB SQLITE and I did a small test program:;
/* Open database. */
sqlite3 *db;
sqlite3_open("data/basedatos.db", &db);
sqlite3_exec(db,"CREATE TABLE [test] ([key] INTEGER, [dat] varchar(64), PRIMARY KEY ([key]))",NULL,0,NULL);
err_code = SQLITE_BUSY;
while (err_code != SQLITE_OK ) {
     sqlite3_exec( db, "delete from test", NULL, 0, NULL );
     err_code = sqlite3_errcode( db );
sqlite3_exec( db, "BEGIN", NULL, 0, NULL );+
for( int i=0; i<_numCartones; i++ ) {
     char buf[1024];
     sprintf_s( buf, sizeof(buf), "insert into test( key, dat) values ( %d, 'test%d' )", i, i );
     sqlite3_exec( db, buf, NULL, 0, NULL );
sqlite3_exec( db, "COMMIT", NULL, 0, NULL );
sqlite3_close(db);I launched the program and insert about 150000 records in 17 seconds. Perfect!
I created a file basedatos.db and basedatos.db-journal subdirectory with files: log.0000000016, __db.001, __db.002, __db.003, __db.004, __db.005, __db.006 and __db.register.
Open it and prove the usefulness dbsql
c: dbsql basedatos.db
select count(*) from test;
150000          ← Ok.
Without closing the program again dbsql run the test program and this will get stuck in the call:
sqlite3_exec( db, "delete from test", NULL, 0, NULL );I close dbsql and automatically releases the "delete from" and the test program again inserted 150,000 records
While this by inserting 150,000 records run it again
c: dbsql basedatos.db
select count(*) from test; [WAIT]
and select count (*) remains locked until you finish the test program, normal thing locks.Once you finish the select TEST responds to 150,000
150000          ← Ok.Without closing the program again dbsql run the test program and this will get stuck in the call:
sqlite3_exec( db, "delete from test", NULL, 0, NULL );I close dbsql and automatically releases the "delete from" and the test program again inserted 150,000 records
while inserting test rerun:
c: dbsql basedatos.db
select count(*) from test;
Error: database disk image is malformed
and in my test program : PANIC: fatal region error detected; run recovery.
Reviewing the files are only: badatos.db, log.0000000031, log.0000000032, log.0000000033, log.0000000034, log.0000000035, log.0000000036, __db.register.
and __db*.* files?

Had accidentally opened the program dbsql.exe while doing speed tests data insertion.
While in a shell to make a select count (*) and I realized that was blocked waiting for the COMMIT release, normal thing in a process BEGIN / COMMIT.
In one test was corrupt database which reduced the test software and simplify the test to repeat the problem.
Today I repeated the test and the situation has changed
1) Run test (all OK, inserted in 18 seconds 150000 entries)
2) DBSQL run and I make a select count (*) (All Ok)
3) DBSQL unsealed test run and stay lock on DELETE FROM
4) DELETE FROM I close DBSQL and not released as yesterday.Repeat several times and I have the same behavior
Move in the test code from "delete from..." begin and commit
sqlite3_exec( db, "BEGIN", NULL, 0, NULL );
err_code = sqlite3_errcode( db );
err_code = SQLITE_BUSY;
while (err_code != SQLITE_OK ) {
sqlite3_exec( db, "delete from test", NULL, 0, NULL );
err_code = sqlite3_errcode( db );
for( int i=0; i<_numCartones; i++ ) {Repeat tests
1)Test run, everything ok in 25 seconds. While inserting test this, I run realizao dbsql and a select count (*) and remains lock until test ends. Everything ok, 150000 records
2)Dbsql unsealed test run it again and stay lock on delete until you close the program dbsql.
3)I close dbsql and releasing the lock of seconds to delete the test the error "PANIC ..." like yesterdayRepeat several times and the behavior is the same, except that no desparencen db files.
If I can not run dbsql test run multiple times without problems.
Could be the problem dbsql and simultaneous access to the database?
I'm going to migrate an application in production since SQLITE to Berkeley DB for testing.
I have confidence in the performance of Berkeley DB and I know the proper functioning it does with subversion, but the subversion server on a server is protected with uninterrupted power.
If I avoid using dbsql while the test software that I have that theoretical security operation will be correct when using Berkeley DB SQLITE layer and especially with unexpected off the machine?
Thanks again for your help

How can I localize the alert "error: PANIC: fatal region error detected..."

My application may corrupt and the operations therefore may fail and post the alert "error: PANIC: fatal region error detected; run recovery ...", and this alert is directly printed in the main process's window.
My question is how can I do to localize this alert in my thread which just deals with the Berkeley DB database?
Thanks

Hi,
You can configure an error callback function. See the run-time error configuration section of the Reference Guide here:
http://www.oracle.com/technology/documentation/berkeley-db/db/ref/debug/runtime.html
It sounds like DB_ENV->set_errcall is what you want:

PANIC: fatal region error detected

i encoutered this error for stress testing.
in the project, we used the transaction and cursor. when the application is runing for a long time, i will receive the err about "PANIC: fatal region error detected". i change the max numbers of transaction, the same error also occurs. when this error occurs, the application can't create any transaction and open any cursor.
somebody can solve this problem? any suggestion appreciated.
thanks

This error should only occur after some message is sent to the error stream (configured with DB_ENV->set_errfile). Can you please post that output?
What operation causes the error (is it during open, or on some read/write)?
Have you tried looking at the output from running "db_stat -e" to see whether some resource is being exhausted?
Are multiple processes (including the Berkeley DB utilities) accessing the environment when the error occurs? Is it possible that any of those processes are using a different version of Berkeley DB than your application?

Fatal:relocation error: While running JDK1.4 on Sun Sparc Generic_106541-08

Hi,
I installed the new jdk1.4 on my Solaris-7 machine. Initially I installed 32-bit jdk1.4 and then installed 64-bit jdk1.4 as indicated on your (sun's) installation page. I used executable binary version of installation for installing the software.
The installation was successfully completed. But while I run java command then it gave following error
Error: failed /export/home/j2sdk1.4.0/jre/lib/sparc/client/libjvm.so, because ld.so.1: ./java: fatal: relocation error: file /export/home/j2sdk1.4.0/jre/lib/sparc/client/libjvm.so: symbol __1cG__CrunSregister_exit_code6FpG_v_v_: referenced symbol not found
Why I am not able to execute any java command with this version? On the same machine I am able to run jdk1.2 and jdk1.3
Please advise on it. It will be of great help If I get some suggestion.
Thanks in Advance,

In particular, patch 106327-14 seems to solve the problem.

929-Fatal MCA Error detected CPU 0

We have a Z420 that will not boot. It returns: 929-Fatal MCA error.CB0/LLC0 error detected CPU 0Memory hierachy error The Manual has no suggested fix. Any Ideas? Thanks!

This could either be a memory failure (try reseating it, moving it to a different slot, or removing or replacing the memory), or a possible CPU failure. (The system is reporting a CPU machine check error, but it could be caused by memory issues). Go into Computer Management, then click on Event Viewer, Windows Logs, and System. Are there any WHEA warnings listed under Source? An easier way to find them is to Filter Current Log, and select Critical, Warning, Verbose, and Error to filter out the (many) Information entries. If the memory is OK, reseating the CPU might help, but this can be tricky. The CPU socket pins are very easily bent during the removal or install process, and extrememly difficult or impossible to repair if damaged. Also, when the CPU heatsink is removed, clean off the thermal paste on both the CPU and heatsink, and use new paste. The paste hardens, and does not give good thermal conductivity if the heatsinks is removed and the paste is not replaced. The CPU operating temperature can increase by 10 deg. C or more. FYI. If the system is under warranty, contact HP so they can fix it.

I have a 20GB database file which I just created by adding around 10,000+ XML documents having the same schema.
I wrote a Python script which traverses thru my directory for XML files and inserts it. It works fine till 1000s of document and then suddenly the process dies. I dont kill it or anything.
Anyway, after that I try to query the database using:
query 'collection("smt.dbxml")/benchmark[@logic= "QF_IDL"]'
and the only thing I get is the above error.
I think I get something more in the beginningbut the number of errors are so much that my terminals window is full and I cant see the first line of message. No logs seems to be created too too.
I run db_recovery on the same path as the DBXML database and all I get is:
[rnadhani@craig exthd]$ /usr/local/dbxml/bin/db_recover -c -v -h .
Finding last valid log LSN: file: 1 offset 28
The DBFILE is created on an external 250GB USB disk formatted using ext3.
What might be the problem? Where can I get logs so I can give you more info.

How many files actually get inserted? It looks like recovery works so you can look at the container. Is the error always in the same place (same number of files)?
Is your environment on the same file system as the container?
If you create a transacted container, the putDocument() call will automatically create a transaction for you if you don't pass it one, so you are using transactions. It doesn't really matter if you create/use your own. I suspect you'll have the same problem, but I don't yet know what that is.
Regards,
George

0x4001100200001005 error while running recovery in pavillion dv2000

here i m trying 2 completely format the hard drive and while doing so it shows the error 0x4001100200001005 and tells to contact HP support if problem persists..... is it h/w problem????
Looking for its quick solution......
help me out...
thanks.....

Errors will be obvious, if you get errors, you will need to check to see how many memory modules are installed, remove all but 1 memory module and re -run the test, if that module passes, take out that module and put in the other one, test it, this is how you find which module is bad if you have more than 1.
After you determine which module is bad, go to one of these sites and buy a replacement module
www.crucial.com
www.kingston.com
sometimes removing and reinserting memory modules from the socket can correct modules that test bad but are not, they just had a bad electrical connection in the memory socket.

Mail Panics every Friday morning with Region error

Every Friday morning around 8:00, Mail dies with the following error and I have to reboot the server. Could someone tell me why this happens?

sounds like your mail db is hosed. get a copy of mailbfr at http://downloads.topicdesk.com/mailbfr/mailbfr-1.0.6.pkg.tar.gz
first i would backup everything to another drive.
I always have mail stores not on the primary OS drive, so you can swap out the OS when it gets funky,
run repair/reconstrcut db on your system.( using mailbfr ) gui tools don't work. their for looking.

Error while running ejbc. Fatal error from EJB Compiler ---- Error while pr

Hi!
I was deploying a test application for a session bean with sun 1 studio 5 and I started getting this message while deploying.
I had tested the bean previously and I had no problems.
I found this in the sun app server 7 release notes, but I don't understand what I'm supposed to do...
"Deployment of CMP beans fails.
The following error is thrown because there are no <query-params> entries in the container-managed persistence (CMP) bean in sun-ejb-jar.xml file:
Error while running ejbc. Fatal error from EJB Compiler ---- Error while processing CMP beans.
Solution
Even if it isn't necessary for the CMP beans, add the query-params tag for finders in the sun-ejb-jar.xml file with the empty parameters."
Here is my sun-ejb-jar.xml file:

Thanks in advance for any help.

http://docs.sun.com/source/817-2175-10/decmp.html
Please go to the above docs and look thru the examples given in it.
Example 2
This query returns all products in a specified price range. It defines two query parameters which are the lower and upper bound for the price: double low, double high. The filter compares the query parameters with the price field:
"low < price && price < high"
The finder element of the sun-ejb-jar.xml file would look like this:
<finder>
<method-name>findInRange</method-name>
<query-params>double low, double high</query-params>
<query-filter>low < price && price &lt
high</query-filter
</finder>
I hope this hepls. In your case u just have to make it null.

HT4623 I trying to update my iPad using iTunes. After connecting to MacBook Pro where is installed all latest software iPad is recognised as iPad, Serial Number: n/a. iTunes run recovery mode, trying to restore iPad firmware, and in the end unknown error

There was some updayts for my iPad 4 automatically downloaded. After installing it, the iPad began to restart itself every few minutes.
I tryed to update my iPad using iTunes. After connecting to MacBook Pro, where is installed all latest software, iPad is recognised as "iPad", Serial Number: n/a. iTunes run recovery mode, trying to restore iPad firmware, and in the end unknown error occured (3). Tried many times, not results. And now iPad stays only in recovery mode, can't switch it off. How can I solve this problem please?

When I restart my iPad the connect to iTunes comes up and stays on until it shuts down again, I have read a report from Apple support suggesting I reinstall iTunes so I might try that again and also your suggestion which i shall also try, but thanks again - rg1547
