Berkeley DB Java Problem

I am facing big problem in using Berkeley DB Java.
I have downloaded 4.7 version.
built it by
+$cd build_unix+
+$sudo ../dist/configure --enable-java+
+$sudo make+
+$sudo make install+
This installed the libs and jar file /usr/local/BerkeleyDB.4.7/lib/ . I have copied dbexamples.jar in that dir
+$ls -l /usr/local/BerkeleyDB.4.7/lib/+
-rw-r--r-- 1 root root  216418 2009-05-15 00:00 dbexamples.jar
-r--r--r-- 1 root root  499438 2009-05-14 23:41 db.jar

lrwxrwxrwx 1 root root      12 2009-05-14 23:41 libdb.so -> libdb-4.7.so
in my ~/.bashrc file I have added
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/BerkeleyDB.4.7/lib/:.
export CLASSPATH=$CLASSPATH:/usr/local/BerkeleyDB.4.7/lib/db.jar
So
+$ echo $CLASSPATH+
+:/usr/local/BerkeleyDB.4.7/lib/db.jar+
+$LD_LIBRARY_PATH+
+:/usr/local/BerkeleyDB.4.7/lib/:.+
I took db,AccessExample.java file and compiled it as default package.
Now when I run that I get
+$java -Djava.library.path=/usr/local/BerkeleyDB.4.7/lib/ AccessExample+

Something must have gone wrong with either the build or the installation. In that directory should be files called "libdb_java-4.7.so" and similar, matching libdb-4.7.so. That is what the Java application can't find.
Can you configure and make again, checking that there are no errors?

  • Berkeley DB Java Edition 3.3.69 is available

    Berkeley DB Java Edition (JE) 3.3.69 is now available for download. The release contains a number of bug fixes, some to problems posted on the OTN forum. The full list of changes may be found in the change log.
    <br>
    <br>
    There is one critical bug fix in this release, described in the change log as follows:
    <br>
    <br>
    "Fix a bug that prevents opening an Environment as read-only under certain circumstances, or causes queries in a read-only Environment to return out of date, and possibly transactionally incorrect, data. The LogFileNotFoundException may be thrown when the problem occurs. [#16368]"
    <br>
    <br>
    This is a fix to a bug that was introduced in JE 3.3.62. If you are currently using 3.3.62 and you are opening the Environment read-only or using the DbDump utility (which opens the Environment read-only), then we strongly recommend that you upgrade to JE 3.3.69.
    <br>
    <br>
    The corresponding Maven POM will be available in a few days.
    <br>
    <br>
    If you are using the JE wrapper plugin for your own Eclipse plugin development AND you open the Environment read-only, you should update that package through
    download.oracle.com/berkeley-db/eclipse. Other DPL Assistant users can consider the update to be optional.

    Morgan,
    Yes, we currently plan to only offer replication for Java 1.5. Our motivations are split between the speed consideration and the codeline issues. We've seen better performance with 1.5. Also taking full advantage of the type safety and concurrent support in 1.5 can end up affecting implementation choices significantly, and can make 1.4 code and 1.5 code diverge a lot.
    As for bug fixing on the 1.4 releases, we don't yet have an official plan. We care very much about supporting our open source users and have been able to provide backwards patches where critical in the past. However, the cost of backporting between 1.5 and 1.4 may be high for some bug fixes, and we'll probably have to decide case by case.

  • Berkeley DB Java Edition 3.3.62 is available

    All,
    Berkeley DB Java Edition (JE) 3.3.62 is now available for download at http://www.oracle.com/technology/software/products/berkeley-db/je/index.html . The release contains new features and bug fixes, many in response to questions and requests posted on this forum. Thanks to all for your help in reporting problems, describing use cases, and patiently waiting for features to appear.
    There's improvements in performance, cache management and memory and disk space utilization. Highlights include:
    * Multiple JE environments can now share the same cache to make better use of memory.
    * The deferred write mode can be configured to differentiate between truly temporary databases and databases which should be persistent.
    * Better cache management for large numbers of databases.
    * Per operation caching policy.
    * Key prefixing.
    * Performance improvements.
    Note that JE 3.3.62 introduces a forward-compatible on-disk file format change from JE 3.2. And for the first time, this release introduces a binary and API incompatibility that will hopefully affect few of you. The full list of changes may be found at http://www.oracle.com/technology/documentation/berkeley-db/je/changeLog.html
    We welcome your continued feedback on the product and feature requests.

  • Can multiple threads share the same cursor in berkeley db java edition?

    We use berkeley db to store our path computation results. We now have two threads which need to retrieve records from database. Specifically, the first thread accesses the database from the very beginning and read a certain number of records. Then, the second thread needs to access the database and read the rest records starting from the position where the cursor stops in the first thread. But, now, I cannot let these two threads share the same cursor. So, I have to open the database separately in two threads and use individual cursor for each thread. This means I have to in the second thread let the cursor skip the first certain number of records and then read the rest records. However, in this way, it is a waste of time letting the second thread skip a certain of records. It will be ideal for us that the second thread can start reading the record just from the place where the first thread stops. Actually, I have tried using transactional cursor and wanted to let the two threads share the same transactional cursor. But it seems that this didn't work.
    Can anyone give any suggestion? Thank you so much!

  • Compatibility issues between Berkeley DB Java Edition and Berkeley DB

    We are trying to use both Berkeley DB Java Edition and Berkeley DB (Java/C) in one of our projects. However, they share the common classes (i.e. EntryDingin.java), but with their own different impementation. Is there any reason that they have to share the same names/packages? Can we request to have the shared java classes going into different packages?
    Thanks
    Yao

    Hello Yao,
    You're correct and the DB and JE products were not designed to run under the same classloader in the same JVM. It is very unlikely that we'll be changing the package names, since that would be very disruptive and yet have no value for the overwhelming majority of users. We will note your request, however, for future reference.
    The two workarounds I know of are:
    1. Use a separate classloader for the use of each product.
    2. Use a tool such as jarjar links (http://code.google.com/p/jarjar/) to rename the packages in one or both of the products.
    Option 2 is not something we (the JE team members) have experience with, but it was used successfully by a JE user. The user also pointed out a bug in the jarjar tool to be aware of: http://code.google.com/p/jarjar/issues/detail?id=21

    Hi Kristoffer,
    We have never updated Maven central -- I think someone else, perhaps who is reading the forum, did that for 5.0.73.  We should update it, but we don't quite have our act together on that.  Hopefully we'll have more info on that soon, but for now you'll need to just copy the jar file or use the Oracle maven repo.
    You should definitely read the release notes and the change log, and decide whether to upgrade.
    BDB has both a commercial and an OSS license.  Due to Oracle policy BDB does not have some of the things you might expect from an OSS project:
    - bug system is not exposed
    - roadmap is not published
    - code contributions are fairly rare, mostly due to the nature of the code -- it's a database engine, and is fairly difficult to change casually.
    What other questions about the process do you have?  I wasn't sure exactly what you wanted to know.

  • Oracle Berkeley DB Java Edition High Availability (White Paper)

    Hi all,
    I've just read Oracle Berkeley DB Java Edition High Availability White Paper
    http://www.oracle.com/technetwork/database/berkeleydb/berkeleydb-je-ha-whitepaper-132079.pdf
    In section "Time Consistency Policy" (Page 18) it is written:
    "Setting a lag period that is too small, given the load and available hardware resources, could result in
    frequent timeout exceptions and reduce a replica's availability for read operations. It could also increase
    the latency associated with read requests, as the replica makes the read transaction wait so that it can
    catch up in the replication stream."
    Can you tell me why those read operations will not be taken by the master ?
    Why will we have frequent timeout ?
    Why should read transaction wait instead of being redirect to the master ?
    Why should it reduce replica's availability for read operations ?
    Thanks

    Please post this question on the Berkeley DB Java Edition (BDB JE) forum Berkeley DB Java Edition. This is the Berkeley DB Core (BDB) forum.

  • Berkeley DB Java Edition and Java 1.4

    As a Berkeley DB Java Edition user we place a very high value on your input. We need your feedback regarding a product requirement for Java 1.5.
    As time goes on we find ourselves implementing more and more performance enhancements based on facilities found only Java 1.5, primarily in the java.util.concurrent package. When we make these enhancements, we currently also maintain support for Java 1.4 although not at the same level of performance. Maintaining and testing this dual mode operation is beginning to slow down our development process. We would like to move as quickly as possible to take advantage of Java 1.5 performance features, but we are constrained by maintaining support for Java 1.4.
    We are therefore planning to require Java 1.5 in the next major release of Berkeley DB Java Edition. Before finalizing this plan, we need your input on whether Java 1.4 support is important to you. Please let us know what your needs are by replying to this forum message.
    Thanks.

  • Berkeley DB Java Edition (JE) and JRuby Interoperability

    I finally got around to doing a quick test of calling Berkeley DB Java Edition (JE) from JRuby (JRuby is a 100% pure-Java implementation of Ruby).
    Before we get to JE and JRuby you probably want to know the answer to this question: "Why you would want to run Ruby on a JVM?" The answer is threefold:
    1. Ruby Performance. A large amount of effort has been put into tuning contemporary JVMs (e.g. Hotspot, Java 6, etc.) and Ruby programmers (through JRuby) can benefit from these tuning efforts. The JRuby guys have set a goal to make JRuby the fastest Ruby implementation available and Sun is certainly throwing their weight behind that effort.
    2. Portability. JRuby is a Ruby interpreter that runs anywhere a Java 5 JVM runs. You download it as a single tar.gz and it will run pretty much anywhere.
    3. Legacy Code. JRuby makes legacy Java apps and libraries available to Ruby programmers (did you ever think you'd see the word "legacy" next to the word "Java"?).
    JE interoperability with JRuby is important because it means that Ruby programmers now have a simple, embeddable, ACID storage engine (JE) available to them.
    To test this interoperability, I cobbled together a simple Ruby test program which does the following:
    * Opens an Environment, Database, and Transaction
    * Creates 10 records with keys 1..10 and marshaled Ruby Time instances as the corresponding data. This uses the Ruby Marshal package for the data binding and the JE Integer binding on the key side. There's no reason why you couldn't use different marshaling packages or methods for keys and data.
    * Commits the transaction,
    * Performs a Cursor scan to read those 10 records and prints out the Time instances, and
    * Searches for and reads the record with key 5 (an arbitrary key) and prints out the Time instance that is the corresponding data
    By the way, hats off to the JRuby developers: all of this code "just worked", out of the box, and most of my two hour investment was spent learning enough basic Ruby to make it all work. If you already know Ruby and JE, then demonstrating this interoperability would take you all of about 10 minutes.
    This was all done at the "base API" level of JE and no modifications to JE were required. I used Transactions in my code, but there's no reason that you need to. Mark and I have been talking about how to integrate JE's Direct Persistence Layer (DPL) with JRuby and we think it can be done with some remodularization of some of the DPL code. This is exciting because it would provide POJO ACID persistence to Ruby programmers.
    Linda and I have been talking about whether it makes sense to possibly use Ruby as a scripting platform for JE in the future. Given how easy it was to bring up JE and JRuby, this certainly warrants some further thought.
    The Ruby code and corresponding output is shown below. By the way, if you see something that I didn't do "The Ruby Way", feel free to let me know.
    I'd love to hear about your experiences with JE and JRuby. Feel free to email me a charles.lamb at <theobviousdomain dot com>.

    In my previous post (Berkeley DB Java Edition in JRuby), I showed an example of calling JE's base API layer and mentioned that Mark and I had been thinking about how to use the DPL from JRuby. Our ideal is to be able to define classes in Ruby, annotate those class definitions with DPL-like annotations, and have the JE DPL store them. There are a number of technical hurdles to overcome before we can do this. For instance, Ruby classes defined in JRuby do not map directly to underlying Java classes; instead they all appear as generic RubyObjects to a Java method. Granted, it would be possible for the DPL to fish out all of the fields from these classes using reflection, but presently it's just not set up to do that (hence the modification to the DPL that I spoke about in my previous blog entry). Furthermore, unlike Java, Ruby allows classes to change on the fly (add/remote new fields and methods) causing more heartburn for the DPL unless we required that only frozen Ruby classes could be stored persistently.
    On thinking about this some more, we realized that there may be a way to use the DPL from JRuby, albeit with some compromises. The key to this is that in JRuby, if a Java instance is passed back to the "Ruby side" (e.g. through a return value or by calling the constructor for a Java class), it remains a Java instance, even when passed around in JRuby (and eventually passed back into the "Java side"). So what if we require all persistent classes to be defined (i.e. annotated) on the Java side? That buys us the standard DPL annotations (effectively the DDL), freezes the classes that the DPL sees, and still lets us benefit from the POJO persistence of the DPL. All of this can be done without modification to JE or the DPL using the currently available release. I cooked up a quick example that builds on the standard "Person" example in the DPL doc and included the code below.

  • Berkeley DB Java Edition and Amazon AWS/EC2, EBS

    In a previous OTN thread titled [BerkeleyDB and Amazon EC2/S3|http://forums.oracle.com/forums/thread.jspa?messageID=2627679&tstart=0] questions were raised about using Berkeley DB Java Edition on AWS/EC2. Specifically,
    (1) Does JE work on AWS/EC2, and
    (2) Can S3 be used as a persistent store for JE.
    To follow up on this, recently I have done some work validating JE on AWS and am happy to report that it works fine (there should be no surprise there). I have run it under 32b and 64b Ubuntu distros with Java 6, but I have no reason to think that it doesn't work on other platforms.
    On the second question, I did no work with S3 as a persistent store. Rather, I ran JE with both the Instance Local Storage and with an EBS volume as Environment storage. In the Instance Local Storage case, AWS/EC2 makes no guarantees of durability if the instance fails. In the EBS case, the durability guarantees are much stronger. Both of these storage mechanisms worked fine with JE.
    I call attention to the performance that I observed with EBS on an m1.large instance type. Raw write/fsync operations were on the order of 1.99 msec which is quite fast. A discussion of this can be found in this [AWS Forum thread|http://developer.amazonwebservices.com/connect/thread.jspa?messageID=111957&#111957].

    Morgan,
    Yes, we currently plan to only offer replication for Java 1.5. Our motivations are split between the speed consideration and the codeline issues. We've seen better performance with 1.5. Also taking full advantage of the type safety and concurrent support in 1.5 can end up affecting implementation choices significantly, and can make 1.4 code and 1.5 code diverge a lot.
    As for bug fixing on the 1.4 releases, we don't yet have an official plan. We care very much about supporting our open source users and have been able to provide backwards patches where critical in the past. However, the cost of backporting between 1.5 and 1.4 may be high for some bug fixes, and we'll probably have to decide case by case.
    Regards,
    Linda

  • JTable displays string in wrong order : my code problem or Java problem ?

    I have the following code that displays data in a JTable, most of the time it works fine, but I've realized when I have a cell with values like : "Snowboarding"+"[123456789]"
    It would display it as : [Snowboarding[123456789
    For a string like : "Chasing toddlers"+"<123456789>"
    It would display it as : <Chasing toddlers<123456789
    It not only moved the last bracket to the front, but also changed its direction from "]" to "[" and from ">" to "<"
    Is there anything wrong with my code ? Or is this a Java problem ?

    * TableSorter is a decorator for TableModels; adding sorting functionality to a supplied TableModel. TableSorter does not store
    * or copy the data in its TableModel; instead it maintains a map from the row indexes of the view to the row indexes of the
    * model. As requests are made of the sorter (like getValueAt(row, col)) they are passed to the underlying model after the row numbers
    * have been translated via the internal mapping array. This way, the TableSorter appears to hold another copy of the table
    * with the rows in a different order.
    * <p/>
    * TableSorter registers itself as a listener to the underlying model, just as the JTable itself would. Events recieved from the model
    * are examined, sometimes manipulated (typically widened), and then passed on to the TableSorter's listeners (typically the JTable).
    * If a change to the model has invalidated the order of TableSorter's rows, a note of this is made and the sorter will resort the
    * rows the next time a value is requested.
    * <p/>
    * When the tableHeader property is set, either by using the setTableHeader() method or the two argument constructor, the table
    * header may be used as a complete UI for TableSorter. The default renderer of the tableHeader is decorated with a renderer
    * that indicates the sorting status of each column. In addition, a mouse listener is installed with the following behavior:
    * <ul>
    * <li>
    * Mouse-click: Clears the sorting status of all other columns and advances the sorting status of that column through three
    * values: {NOT_SORTED, ASCENDING, DESCENDING} (then back to NOT_SORTED again).
    * <li>
    * SHIFT-mouse-click: Clears the sorting status of all other columns and cycles the sorting status of the column through the same
    * three values, in the opposite order: {NOT_SORTED, DESCENDING, ASCENDING}.
    * <li>
    * CONTROL-mouse-click and CONTROL-SHIFT-mouse-click: as above except that the changes to the column do not cancel the statuses of columns
    * that are already sorting - giving a way to initiate a compound sort.
    * </ul>
    * <p/>
    * This is a long overdue rewrite of a class of the same name that first appeared in the swing table demos in 1997.

    * TableSorter is a decorator for TableModels; adding sorting functionality to a supplied TableModel. TableSorter does not store
    * or copy the data in its TableModel; instead it maintains a map from the row indexes of the view to the row indexes of the
    * model. As requests are made of the sorter (like getValueAt(row, col)) they are passed to the underlying model after the row numbers
    * have been translated via the internal mapping array. This way, the TableSorter appears to hold another copy of the table
    * with the rows in a different order.
    * <p/>
    * TableSorter registers itself as a listener to the underlying model, just as the JTable itself would. Events recieved from the model
    * are examined, sometimes manipulated (typically widened), and then passed on to the TableSorter's listeners (typically the JTable).
    * If a change to the model has invalidated the order of TableSorter's rows, a note of this is made and the sorter will resort the
    * rows the next time a value is requested.
    * <p/>
    * When the tableHeader property is set, either by using the setTableHeader() method or the two argument constructor, the table
    * header may be used as a complete UI for TableSorter. The default renderer of the tableHeader is decorated with a renderer
    * that indicates the sorting status of each column. In addition, a mouse listener is installed with the following behavior:
    * <ul>
    * <li>
    * Mouse-click: Clears the sorting status of all other columns and advances the sorting status of that column through three
    * values: {NOT_SORTED, ASCENDING, DESCENDING} (then back to NOT_SORTED again).
    * <li>
    * SHIFT-mouse-click: Clears the sorting status of all other columns and cycles the sorting status of the column through the same
    * three values, in the opposite order: {NOT_SORTED, DESCENDING, ASCENDING}.
    * <li>
    * CONTROL-mouse-click and CONTROL-SHIFT-mouse-click: as above except that the changes to the column do not cancel the statuses of columns
    * that are already sorting - giving a way to initiate a compound sort.
    * </ul>
    * <p/>
    * This is a long overdue rewrite of a class of the same name that first appeared in the swing table demos in 1997.

  • Java problems-locking

    i have 10.6 and the latest download of java. I am trying to run Scottrader Streaming quotes and it locks up constantly/ Tech support suggest it is a java problem and i have a bad instalition of jave which i do not understand as software update installed it for me. the problem is that the java application will suddenly stop running/ any ideas? scottrade suffested reinstalling java. ig that is needed how do i unstall java?

    If Java functions at all, then it is not apt to be an issue with the Java installation. There's really no such thing as a "bad installation of Java". Java will run or it will crash. Lock-ups are generally the result of application errors or communication errors (e.g., it's waiting on a responsed from a server that never comes).
    You can reinstall Java using Pacifist and your restore DVD. I doubt that it will be worth your time, however.

  • Error Code 16 on Mac with Newly-Installed Yosemite (a Java problem?)

    Like many out there I am unable to use CS6 applications at all after an OS update to Yosemite (in my case from 10.8.5, on my 2012 iMac).  I get an Error 16 message, and a Java problem error message.
    I've read many posts about fixing this issue, including the Adobe gospel very specific to this problem—about changing the permissions in a couple of folders—, which I found here: https://helpx.adobe.com/x-productkb/policy-pricing/configuration-error-cs5.html   I did exactly as directed and saw no change in the problem. 
    I also read that the Java version necessary for CS6 products to run on Yosemite is a boondoggle in itself.  Java 6 is apparently necessary for CS6 products to run, but that version is insecure, and besides, it's old.   Java 8 Build 31 is the current and safe version but it apparently is incompatible with none but the most recently-updated Adobe products.  Several posts on Adobe's support pages suggest a hacky fix for this Java issue, which involves downloading and installing the latest Java version from Oracle, and then creating specifically-named empty folders on one's hard drive within a couple of obscure System/Library/Java folders:
    http://oliverdowling.com.au/2014/03/28/java-se-8-on-mac-os-x/
    https://forums.adobe.com/message/7193884
    I did this too, and again saw no change in the problem.
    Re-installing my CS6 suite has not worked, either.  I receive the same error code message when starting up any of the applications.  At this point I've been forced to go back to my previous operating system, since I am heavily reliant on CS6 to do my work each day. 
    I understand that many people are having this trouble after updating to Yosemite, and more than a few posts on these forums indicate this is true even for people like me who've followed Adobe's purported fix that I linked above.  Has anyone in userland or at Adobe found anything lately that could help here? 

    uninstall cs6 and clean (Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6).
    update your os, Java for OS X 2014-001
    then install cs6.

  • Installing 9.2.0.4.0 on EL4 - Can't start netca, JAVA problem!!!!

    Dear all,
    Please help with my Java problem. Thanks in advance.
    After successfully installed Oracle 9.2.0.4.0 on EL4, I tried to start netca but I received this error message:
    [oracle@localhost bin]$ ./netca: line 138: /u01/app/oracle/product/9.2.0.4.0/JRE/bin/jre: No such file or directory

    What do you guys think my problem is?

    I managed to solve this one. For more information you can search the forum with much earlier dates, as far as 2002. I'm very outdated.
    In case you need the solution:
    I tried using java 1.3.1 provided together with the Oracle9iR2 installation Disks instead of 1.1.8.
    1. Delete the JRE link in $ORACLE_HOME
    2. Relink it to 1.3.1 directory
    3. create a jre symbolic link in the bin directory to the .java_wrapper
    4. create another jre symbolic link in the i386/nativethreads directory to the java file
    Good luck
