Open environment failure "DB_RUNRECOVERY"
Hi BDB experts,
This a HA master environment, for some reason unknown, now open environment always returned DB_RUNRECOVERY. The environment was open with flag:
DB_INIT_TXN | DB_INIT_LOCK | DB_INIT_LOG | DB_REGISTER | DB_RECOVER | DB_INIT_MPOOL | DB_THREAD | DB_INIT_REP;
In this case, can the enviroment be recovered? What can be done for this error?
Could you tell me the causes of error "DB_RUNRECOVERY"?
Thanks,
Min
DB_RUNRECOVERY gets returned when there is a suspected issue in the database. You need to run recovery. Chap 11 of BDB Programmers Reference covers the procedures for running recovery. In this case, I would suggest running the db_recover utility. When you run the utility you should ensure that there are no processes connected to the environment and it is closed.
possible causes -- memory errors, disk errors, hw errors, application errors, power failures, cpu errors, human errors There are many paths in the code that can throw this particular error. To figure out the exact trigger for your case, this is something that Oracle support handles. Have you purchased a support contract for BDB?
thanks

Open Environment error : Resource temporarily unavailable
Hi,
I use Berkeley DB 4.5.2 in a system with Intel PXA255, 64MB memory, 512MB USB disk. The system is Linux 2.4.18, compiler is arm-linux-gcc 2.95.3. I put database files on the USB disk (because the file size is more than 72MB), and the disk still got 70% free space (so I don't think the problem is caused by the disk space).
The same program is run pretty well on PC, Intel P4 3.0, 512MB memory, Red hat Linux 4.2 Enterprise (Linux 2.6.9-22), compiler is gcc 4.3.3.
But it could not even open the Environment on the board. One program shows error message:
Environment open failed: Resource temporarily unavailable.
The other program shows error message:
unhandled page fault at pc=0x00019808, lr=0x000197f4 (bad address=0x000000dc, code 0)

They are using the same code:
#define __DEBUG 1
ret = db_env_create(&VitalEnv, 0);
if (0 != ret)
#if __DEBUG
fprintf(stderr, "Error in creating environment handle: %s.\n", db_strerror(ret));
#endif
return ret
}/*endif*/
env_flags = DB_CREATE | DB_INIT_MPOOL;
ret = VitalEnv->open(VitalEnv, "./Data", env_flags, 0);
if (0 != ret)
#if __DEBUG
fprintf(stderr, "Environmet open failed: %s.\n", db_strerror(ret));
#endif
return ret;
}/*endif*/
The only difference is that I put these codes in a function called OpenDB() for the second program, and just put these codes in main() for the first program.
And both of them could not open environment.
I have put the arm version libdb-4.5.so on the USB disk. Everything I did but the problem is still there.Hi Lesslielee,
We will try to fix first the "Resource temporarily unavailable" issue. Is not very clear for me which/what/where application/databases you had moved and when.
Do you have Berkeley DB's additional error reporting turned on? With the error reporting turned on, do you see any additional error information when this exception is thrown? ( http://www.oracle.com/technology/documentation/berkeley-db/db/ref/debug/runtime.html )
From what I understand, when you are storing the databases on the disk (not on the USB drive), the tests are running well, right? When you are moving the database files on the USB drive, are you also moving the environment files? Storing environment files on an NFS file system is not supported.
When Berkeley DB database environment shared memory regions are backed by the filesystem, it is a common application error to create database environments backed by remote filesystems such as the Network File System (NFS), Windows network shares (SMB/CIFS) or the Andrew File System (AFS). Remote filesystems rarely support mapping files into process memory, and even more rarely support correct semantics for mutexes if the mapping succeeds. For this reason, we recommend database environment directories be created in a local filesystem.
Does the problem occur when you run the application for the first time in the new configuration? How did you moved the databases? How did you closed the environment last time?
For more information, please see the "Remote filesystems" section of the Berkeley DB Reference Guide, available in your download package or on our web site at: http://www.oracle.com/technology/documentation/berkeley-db/db/ref/env/remote.html
Thanks,

Open Tunnel Failure Exception still if there APN settings in device
Hi All,
I have writen blackberry application for BB8100,it give me "Open Tunnel failure exception", Though i have write APN Setiing in Advanced options--->Tcp
I am from india
Carrier provides :Airtel
APN:airtelgprs.com
Uname:......
Pass:......
But still m not resolved this problem if any one have resolution please give me that,its really helpfull to me.
Thanks in Advance
Deepakthanks but i haven't been able to find a ksoap specific forum! I have posted the same question on the blackberry forums but there are so many ksoap related issues there that nobody seems able to help.
I was hoping that this issue was more a general error than a ksoap one!

2.3.10 -- Problem openning environment from command-line
I am just starting to learn DB XML. I have downloaded and apparently successfully installed DB XML 2.3.10 (on a Ubuntu 6.06 Linux system). I am reading Danny Brian's book "The Definitive Guide to Bekeley DB XML". In Chapter 5, a command is shown to open/create an environment:
<pre>
$ dbxml -c -h myenv/
dbxml> quit
</pre>
According to the book, I should expect to see 2 files in myenv/ --> __db.001 & __db.002
I have created the directory myenv/ and set my defaullt to its parent. When I try this command, I get the error messages shown below:
<pre>
dbxml -c -h myenv/unable to initialize mutex: Function not implemented
PANIC: Function not implemented
unable to join the environment
dbxml: error at lowest level: DbEnv::open: DB_RUNRECOVERY: Fatal error, run database recovery
</pre>
Adding a couple -vv's to the commands produced no more output! Have I successfully installed 2.3.10? Is there anything I'm doing wrong??
Thanks,
DennyI downloaded the 2.3.10 kit from the Oracle DBXML website a weekago. I unpacked the kit into /usr/local then ran sh buildall.sh!! (2.2.13 is also installed/build in /usr/local)
I just now started another rebuild with the following commands (all while logged on as root:
1. cd /usr/local
2. rm -r dbxml-2.3.10
3. tar -xvf <kit location>
4. chown -R root:root dbxml-2.3.10 (was owned by cupsys:users??!!)
5. sh buildall.sh
This time, as all the checking messages came by, I noticed that selected mutex = x86/gcc-assembly
There is one big difference between what I had been doing and this latest attempt: Previously, I unpacked the kit inot my home directory, then did:
sudo mv <home copy of dbxml> /usr/local
sudo chown -R root:root ......
sudo sh buildall.sh
Could using sudo been the cause of my problem??!!
I just checked the db-4.5.20 config.log and saw
db_cv_mutex=x86/gcc-assembly
Earlier this week (as reported in an earlier response to this post), db_cv_mutex was set to POSIX-something!!??!!
I am hopeful!!

Hello,
I have an application in Java that I deploy in Glassfish 3. The database is Berkeley DB XML.
The application is used by several clients, so I have one environment for each client.
When I deploy the application I run this code to each client, to open every environment.

After using the application for many days, the application failed and it hangs. The glassfish went down.
So when I deploy the appllication again it stops in the line and I get no exception or error.
if (XML_MANAGER.existsContainer(containerMessage.getCanonicalPath()) != 0) {Then I started to debug the code and I realize that when I open the environment in this line:
env = new Environment(new File(ENVIRONMENT_PATH_NAME), ENVIRONMENT_CONFIG);then configuration of ENVIRONMENT_CONFIG.getRunRecovery() was set to false.
So then I changed the settings and I set ENVIRONMENT_CONFIG.setRunRecovery(true).
After that I deployed the application again and I got this errors:

Error opening environment more than once
Hi,
I have two java classes which both need to access a container in an environment (in parallel). When the first class is instantiated the environment is opened successfully. However, when the second class subsequently attempts to open the same environment I get an error. (I do not want to close the env from the first class, while the second class does its thing)
The classes are Stylesheet extensions for an xmleditor which allows the stylesheet to look up item ID codes and display their names to the user by looking up the values in an xml file stored in a bdbxml container. There is a situation where two different objects need to have access to the environment at the same time - but its giving me an error when I instantiate the env for the second time - without having closed the first one)
Any help would by gratefully received
Kind Regards
Swami Kevala
I thought I could create multiple handles to the same environment?First is a class to encapsulate the environment (lifted mostly from the example code)

private File path2DbEnv_ = null;
public DbEnv(File path2DbEnv)
throws Throwable {
if (! path2DbEnv.isDirectory()) {
throw new Exception(path2DbEnv.getPath() +
" does not exist or is not a directory.");
EnvironmentConfig config = new EnvironmentConfig();
config.setCacheSize(50 * 1024 * 1024);

config.setErrorStream(System.err);

config.setLogAutoRemove(true);
dbEnv_ = new Environment(path2DbEnv, config);

Now to explain what is happening:
When I open an xml document in xmlmind, it displays the document according to a prespecified CSS sheet. Sometimes the CSS rules alone are not sufficient to achieve the necessary effect/functionality, so the API allows you to write your own class, which contains methods to do what you want. As soon as the xml document is displayed, the CSS extension class gets instantiated.
Here is my extension class (called StyleSheetExtension). It contains a method called getKeywords. This method can then be invoked from within the CSS sheet, and is used to replace the keyword ID codes in the xml document with their corresponding keyword names - stored in an xml reference look-up document...

This instance (and consequently the newly created env and container objects) stay alive until the document is closed.
The xmlmind API also allows you to specify custom classes that will return a component that can be embedded in the stylesheet. (My class returns a JButton which - when clicked - brings up a dialog box which allows the user to specify /modify/addnew keywords to the selected text). As soon as the button is pressed I create a new env and container instance, for the duration of the pop-up window (since I have no way to pass the reference to the existing environment created by the StyleSheetExtension class.
Here's the class defn: (Here goes!) The env and container stuff is at the start of the nested-nested class called KpForm.

DB_VERSION_MISMATCH error when opening environment.

OutOfMemoryError when opening environment using Java API
I've been getting a strange error recently and I can't seem to figure out why. Whenever my DBXML environment gets opened, I receive a "java.lang.OutOfMemoryError: Cannot allocate memory" error. The machine has over 700 MB of free RAM. Here is the code I use to create/open the environment.
EnvironmentConfig envConf = new EnvironmentConfig();
envConf.setAllowCreate(true); // If the environment does not exits, create it.
envConf.setInitializeCache(true); // Turn on the shared memory region.
envConf.setInitializeLocking(true); // Turn on the locking subsystem.
envConf.setInitializeLogging(true); // Turn on the logging subsystem.
envConf.setTransactional(true); // Turn on the transactional subsystem.
envConf.setThreaded(true); //Turn on thread-safe
envConf.setLogRegionSize(500000); //Increase logging region
envConf.setErrorStream(System.err); //Set error stream
envConf.setMaxLocks(5000); //Set max # of locks
envConf.setMaxLockers(5000); //Set max # of lockers
envConf.setMaxLockObjects(5000); //Set max # of lock objects
envConf.setMaxMutexes(10);
//Set the error stream to write to a log file
String fileName = SystemProps.DATA_HOME + "/dbxml.log";
File f = new File(fileName);
FileOutputStream fos = new FileOutputStream(f);
envConf.setErrorStream(fos);
return new Environment(envHome, envConf);
Is there something specific I'm doing here that would require lots of RAM? Could it be related to the size/contents of my DBXML containers?
Thanks in advance.I'm not exactly sure why this worked, but running recovery seems to have fixed my problem.

Open Environment with different flags
Hi,
Is it correct to open an environment with different flags from that when it was created? For example, I use DB_INIT_CDB to open an environment directory which was not created using this flag? Will the environment support concurrency then? Thank you.on subsequent 'reopens' you should use the same set of flags as used when it the db files were created. The exception is with create flag. If you create a db file with one purpose in mind and want to change that purpose, you should recreate the db file with a new set of flags. You can use dump/restore to dump and reload the data in the newly created db file
thanks

Ligthroom 2-open catalog- failure to relaunch (using Win XP)
When I try to open (an exiting) catalog the dialog box telling me LR 2 must relaunch to open this catalog pops up and asks is that what I want to do. When I respond yes LR 2 closes but then it never re launches. I upgraded from LR 1.4 or the latest LR version. Anybody know what is going on ?
Hi
Are you sure that you entered the ADDRESS correctly? It seems that in hosts you wrote TC0239.NBTH and in tnsnames.ora and listener.ora you entered NBTH.TC0239.
Ensure that the executable for the server exists (perhaps "oracle" is missing.)
Error: ORA-12545 / TNS-12545
Text: Connect failed because target host or object does not exist
Cause: The address specified is not valid, or the program being connected to
does not exist.
Action: Ensure the ADDRESS parameters have been entered correctly; the most
likely incorrect parameter is the node name. Ensure that the executable
for the server exists (perhaps "oracle" is missing.) If the protocol is
TCP/IP, edit the TNSNAMES.ORA file to change the host name to a numeric
IP address and try again.TNS-12545 "Connect failed because target host or object does not exist"

Bdb deadlocks when opening database
When I call _dbp->open(), the library hangs. I am attempting to test how BDB works during system crashes, in order to code my application appropriately, but these hangs are difficult to work with.
I am running multiple processes all reading and writing to a single database. I then kill off the processes one at a time, until one of the terminations hangs all the other processes reading or writing to that database. I understand the database may at that time be in a bad state and may need to be re-opened with the DB_RECOVER flag, but I don't get any kind of an error message on the other processes reading or writing to the database. They just hang. (it looks like they are waiting for the lock of the terminated process to be closed).
I have code to check for a DB_RUNRECOVERY error number returned as part of the exception thrown during a db->open() operation, so I can then can db->open() again with the DB_RECOVER option, but db->open() never returns.
I have tried setting the transaction timeout values and lock timeout values, but nothing seems to be working.
I have tried working with the DB_REGISTER option, but would prefer not to limit each process to a single environment. I'd like to hide the BDB environment entirely from the caller and simply require the database name.
Any assistance would be appreciated,
ToddI do not have the option of launching a separate process to monitor the database. Unfortunately, I have resigned to the fact I must provide a separate thread to test for failures and deadlocks.
As a result, I have created a static process-wide "EnvironmentManager" class to maintain a collection of Environments and Databases opened by the current process. This ensures the process will only have a single instance of any Environment open. As a result, I should be able to open my environment(s) with DB_REGISTER and DB_RECOVER.
I also created a monitor thread. This thread does the following:
foreach open environment
envp->lock_detect(0,DB_LOCK_DEFAULT,NULL);
envp->failchk(0);
If a DbException with errno set to DB_RUNRECORY occurs, I do the following:
Close each database opened within the faulted environment
Close the environment
Re-Open the environment
Re-Open each database
I would like to cycle through any open transactions, locks and cursors to close them, but it appears I do not have access to them.
My test engine runs in an infinite loop doing the following:
- Open Environment and Database
- Write 200 records
- Read 200 records
- Get a count of records
- Close the database and environment
To test the failures, I launch multiple instances of the test engine then kill the processes one at a time. Obviously my production application with do a normal shut-down under normal conditions, but I need to handle time when an application crashes unexpectedly. I understand problems will occur, my goal is simply to get the system to throw exceptions that I can recover from. I need to resolve all dead-lock issues that can hang my application and all unexpected application-aborts that occur as a result of DB_ASSERT failures.
The problems I am now encountering after implementing all of this:
1) After a process has crashed and I attempt to ‘recover’ from within another running process, I am getting an exception regarding an open file handle to __db.register.
PANIC: fatal region error detected; run recovery
File handles still open at environment close
Open file handle: C:\__db.register
assert failure: ..\mutex\mut_win32.c/174: "__ip != NULL && __ip->dbth_state != THREAD_OUT"
2) If I try to run the same application multiple times quickly by double clicking on the same executable, I get the following exception:
DB_REGISTER limits processes to one open DB_ENV handle per environment
DbEnv::open: Invalid argument
Both of these issues appear to be with the DB_REGISTER option being specified when I open the environment, but things get much murkier if I remove that option.
If I do not specify DB_REGISTER and DB_RECOVER on the command line, it is possible for my call to DbEnv->Open() to hang indefinitely. Otherwise, I would call Open() once and if it failed, call it again with DB_RECOVER.
Please let me know how to proceed. How have other people handled running Berkeley DB across multiple processes?
Regards,
Todd -
Environment recovery required when accessing lockstats
we just upgraded from 2.4.* to 2.5.16 and we are trying to figure out our best locking strategy and running into some issues. While displaying stats works fine on most of our environments, it crashes in one every time with
<pre>
logging.error("Lock stats: %s"%env.lock_stat())
bsddb3.db.DBRunRecoveryError: (-30974, 'DB_RUNRECOVERY: Fatal error, run database recovery -- PANIC: fatal region error detected; run recovery')
</pre>
I get the same error when trying to get documents from the shell. These happen even after recovery. Any idea what could be amiss here or what I need to reset to fix it?
Thanks!
eleddyHi Bogdan -
The flags are
<pre>
# open environment flags
DB_CREATE|DB_THREAD|DB_INIT_LOCK|DB_INIT_LOG|DB_INIT_MPOOL|DB_INIT_TXN|DB_MULTIVERSION
# recover flags, always run on startup
DB_CREATE|DB_THREAD|DB_INIT_LOCK|DB_INIT_LOG|DB_INIT_MPOOL|DB_INIT_TXN|
DB_RECOVER|DB_MULTIVERSION
#manager open flgs
DBXML_ADOPT_DBENV|DBXML_ALLOW_AUTO_OPEN
# create container flags
DB_CREATE|DB_EXCL|DBXML_TRANSACTIONAL
#open container flags
DBXML_TRANSACTIONAL
# other settings
environment.set_lk_detect(DB_LOCK_OLDEST)
environment.set_lk_max_lockers(40000)
environment.set_lk_max_locks(20000)
environment.set_lk_max_objects(10000)
environment.set_lg_max(104857600)
environment.set_lg_bsize(20971520)
environment.set_lg_regionmax(41943040)
environment.set_lg_dir("logs")
environment.set_data_dir("data")
environment.set_timeout(1000000, DB_SET_TXN_TIMEOUT)
environment.set_timeout(1000000, DB_SET_LOCK_TIMEOUT)
environment.set_cachesize(0, 1073741824, 3)
</pre>
Let me know if I missed some flags. I can't seem to add any documents to this environment either, via api or shell. It seems to be one container. When I try to add via the shell I get
<pre>
stdin:6517: putDocument failed, Error: Invalid argument
dbxml> exit
Segmentation fault
</pre>
Finally, If I run the same command in a non-transacted shell environment everything runs smoothly. I'm trying a dump and reload test now but its 9GBs and live data so doing that for real isn't something I'm very excited about. FWIW we have another db that is crashing twice a day but its not re-creatable yet and goes straight to segfault. The issues don't seem to be related except they both started after the upgrade.
Thanks in advance!

Most simple code always recovers the environment
Hi,
The code below recovers the environment on every run. This happens, if
I specify DB_REGISTER without DB_RECOVER.
Version: 4.6.21
#include <stdio.h>
#include <db.h>
#ifdef WIN32
#define DIRECTORY_ENVIRONMENT "C:\\Temp"
#else
#define DIRECTORY_ENVIRONMENT "/tmp"
#endif
static DB_ENV *environment = NULL;
static int connect( int flags )
db_env_create( &environment, 0 );
environment->set_errfile( environment, stderr );
return environment->open( environment, DIRECTORY_ENVIRONMENT, flags, 0644 );
int main( int argc, char *argv[] )
int status = connect( DB_CREATE | DB_INIT_MPOOL | DB_INIT_LOCK | DB_INIT_LOG | DB_INIT_TXN | DB_REGISTER );
if( status == DB_RUNRECOVERY )
printf("Run recovery...\n");
status = connect( DB_CREATE | DB_INIT_MPOOL | DB_INIT_LOCK | DB_INIT_LOG | DB_INIT_TXN | DB_RECOVER ); // "DB_REGISTER" fails
status = environment->close( environment, 0 );
return 0;
}Hello,
Please let me know if I am misunderstanding your question.
Using DB_REGISTER will check to see if recovery needs to be performed
before opening the database environment. If recovery needs to be
performed for any reason (including the initial use of the DB_REGISTER flag),
and DB_RECOVER is also specified, recovery will be performed and the
open will proceed normally. If recovery needs to be performed and DB_RECOVER
is not specified, DB_RUNRECOVERY will be returned. If recovery does not need
to be performed, the DB_RECOVER flag will be ignored.
Thanks,

Safari fails to open after recent hard drive replacement and data transfer from time machine
The hard drive was replaced by apple under replacement scheme due to seagate failures. It was reloaded with latest ios, but safari would not open, reported failure.
I had re -installed my backed up info from time machine. i did go into back ups and copied previous safari app, and dropped it on my desk top. It opened ok. Is there an easy way to get this app onto the system and delete the faulty safari file.
Hope this makes sense.guess what, all fixed, the safari app installed by apple on new hard drive was 5 something, but 6.02 was needed, i installed 6.02 but it told me i needed OSX10.8.2 which cost me £13.99 but it now works.

Multiple environment instances in the same process with DB_REGISTER flag
Hello,
I'm having two applications in the tomcat that should use the same environment. I have the DB_REGISTER flag set, and since tomcat has a java single process for all applications, I can't open an environment in the second application since I get a "DB_REGISTER limits processes to one open DB_ENV handle per environment" error message. This is understandable. So my question is: is there a way to "join" the first opened environment instance. Or do I have to run applications in two different processes, i.e. using 2 tomcat instances?
Thanks,
VyacheslavThanks for reply Sandra.
I have a follow-up question. Is it possible to get an environment instance if it's already opened in the process. For instance like:
Application1 in the tomcat process:
Environment env = new Environment(envHome, envConfig) //openning an env under "envHome" directoryApplication2 in the same tomcat process:
Environment env;
try{
env = new Environment(envHome, envConfig) //openning an env under "envHome" directory
} catch (DbException e) {
if(isAlreadyOpenedException(e)) { //checking that our exception is "DB_REGISTER flag permits only 1 opened env handle per process"
env = Enviroment.getEnvironmentHandleFromTheSameProcess(); //here I'm improvising. Is there any similar method?
} So my question is if it's something that is possible.
Thanks in advance,
Vyacheslav
