  • Defines JEE 5 the handling of commit error using bean managed transactions?

    - by marabol
    I'm using glassfish 2.1 and 2.1.1. If I've a bean method annotated by @TransactionAttribute(value = TransactionAttributeType.REQUIRES_NEW). After doing some JPA stuff the commit fails in the afterCompletion-Phase of JTS. GlassFish logs this failure only. And the caller of this bean method has no chance to know something goes wrong. So I wonder, if there is any definition how a jee 5 server has to handle exceptions while commiting. I would expect any runtime exception. I'm using stateless beans. With SessionSynchronisation I could get the commit failue, if I use statefull beans. Is it possible to intercept, so I can throw an exception, that I've declared in my interface? This is the whole exception stacktrace:

  • Oracle SqlPlus Command Line: There's a way to concatenate set options?

    - by Lex
    Heya, I need to set up some SET options in Oracle SQLplus command line program each time I use it, such as SET HEADING OFF and the likes to beautify my results. I found that I always have to input each line separately so Set different options and this is becoming annoying since I need to access it many times a day. I found that there's no way to separate different SET commands with semicolumns because it doesn't accept it: SET HEADING OFF; SET LINESIZE 100; returns an error A solution could be adding them to a control script and create a shell alias, but I know control scripts execute and then exit and don't return you control over the command line. So, anybody knows another solution? Or am I missing something?

  • Does SQL Server Compact Edition (SqlCe) have a SNAPSHOT table like Oracle Lite?

    - by MusiGenesis
    In Oracle Lite, you can create a SNAPSHOT table which is like a normal table except that it tracks changes to itself. The syntax is CREATE SNAPSHOT TABLE tblWhatever ... and you can perform CRUD operations on it like a normal table. To get the change information, you query the table like this: SELECT * FROM tblWhatever + WHERE ... which returns all the rows in the table (including deleted ones) meeting the WHERE clause, and you can access each row's row_state column as a normal field (which is invisible to a normal SELECT * FROM tblWhatever WHERE ... query). Is there some way to do the same thing with Sql Compact Edition (3.5) - i.e. create a table that tracks changes without using RDA?

  • Difference in select for update of ... in Oracle Database 10g and 11g

    - by sax
    Hi, I found out that Oracle Database 10g and 11g treat the following PL/SQL block differently (I am using scott schema for convenience): DECLARE v_ename bonus.ename%TYPE; BEGIN SELECT b.ename INTO v_ename FROM bonus b JOIN emp e ON b.ename = e.ename JOIN dept d ON d.deptno = e.deptno WHERE b.ename = 'Scott' FOR UPDATE OF b.ename; END; / While in 10g (10.2) this code ends successfully (well NO_DATA_FOUND exception is raised but that is expected), in 11g (11.2) it raises exception "column ambiguously defined". And that is definitely not expected. It seems like it does not take into account table alias because I found out that when I change the column in FOR UPDATE OF e.empno (also does not work) to e.mgr (which is unique) it starts working. So is this some error in 11g? Any thoughts?

    Is there a way to give a subquery in Oracle 11g an alias like: select * from (select client_ref_id, request from some_table where message_type = 1) abc, (select client_ref_id, response from some_table where message_type = 2) defg where abc.client_ref_id = def.client_ref_id; Otherwise is there a way to join the two subqueries based on the client_ref_id. I realize there is a self join, but on the database I am running on a self join can take up to 5 min to complete (there is some extra logic in the actual query I am running but I have determined the self join is what is causing the issue). The individual subqueries only take a few seconds to complete by them selves. The self join query looks something like: select st.request, st1.request from some_table st, some_table st1 where st.client_ref_id = st1.client_ref_id;

  • How do I run Eclipse using Oracle's new 1.7 JDK for the Mac?

    - by sanity
    I'm trying to get the new 1.7 JDK working with Eclipse (this is Oracle's official release). I don't mean just pointing Eclipse to it so you can use it in projects, this works fine, but actually making Eclipse run using the 1.7 JVM. I've moved the new JVM to the top of the list in Java Preferences, but Eclipse still starts with 1.6. If I disable 1.6 in Java Preferences I get a dialog immediately after I double-click on Eclipse saying "Failed to create the Java Virtual Machine". edit: I added the following to my eclipse.ini just before the -vmargs: -vm /Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home/bin/java Yet in the Eclipse installation details dialog I still see: java.runtime.version=1.6.0_31-b04-415-11M3646 edit 2: here are the contents of my eclipse.ini file: https://gist.github.com/2512578

  • Is Berkeley DB XML a viable database backend?

    - by w00t
    Apparently, BDB-XML has been around since at least 2003 but I only recently stumbled upon it on Oracle's website: Berkeley DB XML. Here's the blurb: Oracle Berkeley DB XML is an open source, embeddable XML database with XQuery-based access to documents stored in containers and indexed based on their content. Oracle Berkeley DB XML is built on top of Oracle Berkeley DB and inherits its rich features and attributes. Like Oracle Berkeley DB, it runs in process with the application with no need for human administration. Oracle Berkeley DB XML adds a document parser, XML indexer and XQuery engine on top of Oracle Berkeley DB to enable the fastest, most efficient retrieval of data. To me it seems that the underlying ideas are technically sound and probably more mature than the newer document-based DBs like CouchDB or MongoDB. It has support for C, C++, Ruby and Perl, as far as I can determine. It even has HA-capabilities like automatic replication using a master/slave model with automatic election. However, I can't seem to find any projects that use it. Is there something fundamentally wrong with it? Is the license too onerous? Is it too complicated? Why is it not being used?

  • Reconnect to GPRS from J2ME

    - by ouzz
    Dear All, I have a little problem. I have developed a midlet application that call some webservices through internet. I'm using cell phones with GPRS connection. For some time it runs as I wanted, run the apps, call the webservices through the GPRS, it returns the result, call the webservices again, and so on. But say, I call the webservices and after the apps return the result I needed, I left it for a while. The next time I continue to access the webservices, the apps takes a while to connect through the GPRS. In nokia, it is marked with a G in a box. In SE it is marked with a glowing globe. This 'G' in the box or the glowing globe will appear after a while or won't appear at all, but the apps is still trying to connect to the internet. Does it come from my apps or it come from the cell phone? And could I know [or the apps knows] that at the moment the apps tries to connect the GPRS is ready? Thanks a lot for your responses...

  • Automatically Kill/Restart Process(es) When Memory is Critically Low

    - by nemesisfixx
    I have a Debian Wheezy VPS box where am running a couple of Django apps in production. Ideally, would have tried addressed my current memory footprint issues by optimizing the apps, adding more RAM or augmenting with Swap. But the problem is that I doubt there's much memory optimization I'd milk from optimizing the Django apps (the stack being open-source and robust), and adding RAM is a cost constraint for me (this is a remote VPS), also, the host doesn't offer options to use Swap! So, in the meantime (as I wait to secure more resources to afford more RAM), I wish to mitigate the scenarios where the server runs out memory so that I just have to request a VPS restart (as in, at that point, I can't even SSH into the box!). So, what I would love in a solution is the ability to detect when a process (or generally, total system memory usage) exceeds a certain critical amount (for now, example the FREE RAM falls to say 10%) - which I've noticed occurs after the VPS's been up for long, and when also traffic is suddenly much to some of the heavy apps (most are just staging apps anyway). So, I wish to be able to kill/restart the offending process(es) - most likely Apache. Which solution when done manually in these situations has restored sane memory usage levels - a hint that possibly one or more of the Django apps has a memory leak? In brief: Monitor overall system RAM usage When FREE RAM falls below a given critical threshold (say below 10%), kill/restart the offending process(es) - or simpler, if we assume from my current log analysis (using linux-dash) that Apache is often the offender, then kill/restart it. Rinse and repeat...

  • eXist-db: can't start webstart client on a closed port, reverse proxied via apache

    - by rvdb
    I am configuring an Apache HTTP server so it reverse proxies requests starting with /app/ to an eXist-db instance running in a Tomcat server, on port 8082. This port has been closed in the firewall and is inaccessible to the outer world. Following the eXist documentation, I have following rules in place in my httpd.conf file: ProxyPass /apps/ http://localhost:8082/ ProxyPassReverse /apps/ http://localhost:8082/ ProxyPassReverseCookiePath /apps/ / All goes well for requests to e.g. 'http://mydomain/apps/exist/index.xml'. Yet, the webstart client (accessible at 'http://localhost:8082/exist/webstart/exist.jnlp' on the web server) doesn't work behind the proxy. While 'http://mydomain/apps/exist/webstart/exist.jnlp' does generate a valid exist.jnlp file, that file can't be executed. The reason seems quite obvious: apparently, the eXist-db instance generating the exist.jnlp file only sees the proxied request as: 'http://localhost:8082/exist/webstart/exist.jnlp'. Yet, since the exist.jnlp file is executed on the client, that reference is meaningless (unless the client computer happens to have an eXist-db instance running on that port). Executing the exist.jnlp file hence fails with a 'connection refused' error. Yet, there's no problem at all connecting a local eXist-db Java client to the proxied eXist instance with the URL xmldb:exist://mydomain/apps/exist/xmlrpc. The problem lies in generating the webstart exist.jnlp file, which seems to need access to a publicly accessible URL. However, opening port 8082 and replacing the Proxy references to 'http://localhost:8082' with 'http://mydomain:8082' IMO rather destroys the point of reverse proxying. Do others have had success reverse proxying eXist-db on a closed port behind Apache? Are there perhaps some Proxy configuration settings I have overlooked (I'm no expert at all) that can make eXist see the original request instead of the proxied one? Kind regards, Ron

  • nginx reverse proxy to apache mod_wsgi doesn't work

    - by user11243
    I'm trying to run a django site with apache mod-wsgi with nginx as the front-end to reverse proxy into apache. In my Apache ports.conf file: NameVirtualHost 192.168.0.1:7000 Listen 192.168.0.1:7000 <VirtualHost 192.168.0.1:7000> DocumentRoot /var/apps/example/ ServerName example.com WSGIDaemonProcess example WSGIProcessGroup example Alias /m/ /var/apps/example/forum/skins/ Alias /upfiles/ /var/apps/example/forum/upfiles/ <Directory /var/apps/example/forum/skins> Order deny,allow Allow from all </Directory> WSGIScriptAlias / /var/apps/example/django.wsgi </VirtualHost> In my nginx config: server { listen 80; server_name example.com; location / { include /usr/local/nginx/conf/proxy.conf; proxy_pass http://192.168.0.1:7000; proxy_redirect default; root /var/apps/example/forum/skins/; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } } After restarting both apache and nginx, nothing works, example.com simply hangs or serves index.html in my /var/www/ folder. I'd appreciate any advice to point me in the right direction. I've tried several tutorials online to no avail.
