• Performance (listener APEX) glassFish and ADR issues

  Hello world

  We have a number of applications available APEX to APEX Listener installed on 4.1 GlassFish (Open Source Edition). The APEX is version 2.0.9.224.01.07.

  Any installation is using the default values, the documentation available now.

  The problem is that after a while (two days, maybe weeks) the answer is really slow, which means you have to wait a few minutes to change pages or get the application to react. While everything works normally by another instance of GlassFish and auditor of the APEX, which means that everything is ok with the database and the problem must be with the GlassFish and/or listener of the APEX. After you restart GlassFish domain things to improve for a while, but finally that we are facing problems of performance even. There is nothing suspicious in the newspapers of GlassFish, and we do not know where to look further.

  I tried the web search for more information on how to configure GlassFish and APEX listener for the documentation and production environments, but did not find much. We increased settings memory JVM for GlassFish to 2 GB, but I would like to know is there something else about the GlassFish settings (son HTTP, JDBC, pool etc.) we could do to avoid the problems described, or is there a way to detect what is the real problem. Any suggestions or pointers to relevant documents?

  Thanks in advance,

  Bruno

  For ADR + Glassfish performance should be on two fronts:

  • Side of GlassFish:

  As you use 4.1 GlassFish (Open Source Edition) you should refer to the official documentation for Glassfish 4.

  Reference: https://glassfish.java.net/docs/4.0/performance-tuning-guide.pdf

  But as I've used Oracle Glassfish Server 3.1 which comes with the integrated tuner. I just follow the following documentation:

  Reference: https://docs.oracle.com/cd/E18930_01/html/821-2431/toc.html and https://docs.oracle.com/cd/E18930_01/html/821-2431/gkxwm.html

  • Side of ADR:

  The performance tuning side ADR includes the correct JDBC settings in the ADR configuration files.

  Reference: http://krisrice.blogspot.in/2012/05/apex-listener-jdbcsecurity-setup.html

  So, set your ADR for instance so that you get the performance you want. For this you will need: change the JDBC settings-> load/stress test and repeat this operation.

  Stress/load tests is shown by Morten Bråten in the following blog in his blog series about ADR.

  Reference: ORA-00001: Unique constraint violated: ADR, installation Oracle XE and Apex on CentOS - part fourth: Stress tests

  NOTE: This blog is for ADR + Apache Tomcat, but ADR configuration settings remain the same in your case.

  Finally, if you want to see more practical best ADR with Oracle APEX follow the slides for "ADR in the Production" by Dietmar Aust.

  Reference: daust_de: Oracle XE / APEX: presentation for my ADR slides talk to KScope 2015

  NOTE: This presentation is also to ADR + Apache Tomcat, but things related to ADR are same in your case.

  Also, as this thread is related to ADR, you must move this thread to the appropriate forum: ADR, SODA & JSON in the database

• upgrade to 12 c causing problems with APEX 4.2.5

  Hey everyone, our dba updated our database this past weekend at 12 c.  Today, we have problems with one of our more complex pages.  Here's our software configuration where after upgrade:

  APEX: Application Express 4.2.5.00.08

  Database: Oracle Database Enterprise Edition Release 12.1.0.2.0 - 64 bit Production 12 c

  The page in question has dynamic actions which fire when a user clicks a button.  The action has 3 processes related to it.  The first is javascript that runs that changes some css classes.  That seems to work.  The second is supposed to be executing pl/sql code (with a dynamic process page element).  This does not appear be to fire.  I watched with firebug and chrome dev tools, but it seems that no ajax call is sent when I click on the button.

  The page seems to generate exceptions in the scenes.  I see the following in newspapers several times on the page.

  ORA-20987: APEX - ORA-00001: unique constraint (APEX_040200.WWV_FLOW_COLLECTIONS_UK) violated

  Unfortunately, I can't determine if what is happening on the loading of the page or under dynamic actions.  Apparently not loading the linked page cause I can't recreate it all by refreshing the page.  But I don't see how it could be created by the dynamic action since they don't seem to be calling the server either.  (no ajax call I see)

  Does anyone know of none known between 4.2.5 and 12 c?  Everything worked well Fri/Sat, so the upgrade must be the cause.

  Thank you!

  It looks like given the scope of the implemented dynamic actions in dynamic instead of static electricity was the problem.  Their transition to static seems to have fixed everything.  Not sure if it "just worked" under the previous version and 12 c was somehow more special or if the parameter got reversed somehow in the process, but it was certainly before.

  Well.  I'll consider it fixed!

• ADR 2.0.10 and APEX 4.2.2 in the problem of the PDB

  I have APEX installed 4.2.2.0.11 in PDB on Oracle RDBMS 12.1.0.2. OS - Windows Server 2012 R2.

  With Oracle HTTP Server (mod_plsql) or mod_owa, there is no problem, everything works fine.

  I try to use ADR 2.0.10. But APEX does not work...

  I start ADR in stand-alone mode, without problems.

  When I try to open builder (http://localhost: 8888/ADR/or http://localhost: 8888/ADR/apex) I get a blank page.

  There is no errors in newspapers and I see in v$ session three sessions ADR.

  Then I created the simple test like this procedure:

  create procedure apex_public_user.cgi_env is
  begin
  owa_util.print_cgi_env;
  end;
  
  
  
  

  And called http://localhost: 8888/ADR/cgi_env

  Procedure is executed successfully and print cgi variables.

  Where is my problem? In the configuration of ADR or...?

• After the upgrade of the APEX 4.2.0.6, I don't see any change

  Hello

  I have a production APEX running version 3.1. I downloaded APEX 4.2.0.6 and installed. I didn't remove the previous APEX users because I fear that it would change anything prevents existing applications runs properly.

  When I connect to APEX http://xxxxxxx:7780/pls/apex / ,, I don't see any change in the user interface. Where is the 4.2.0.6 APEX version?

  I can see there are users in the previous version. But I've not deleted the. What prevents the Apex 4.2 runnig?

  SQL > SELECT username

  2 FROM dba_users

  3. WHERE (username AS USER OR name "FLOWS_ %" LIKE '% APEX_')

  4 AND USERNAME NOT IN)

  5. SELECT "FLOWS_FILES".

  Hello Kiran

  I redid all installation steps and found that I now have this error:

  Service temporarily unavailable

  The server is currently unable to handle the request due to a temporary overloading or maintenance of the server.

  When are you facing this error?

  • Access to the APEX Oracle Application Builder (http://someserver:7780/pls/apex)
  • Accessing an application in Oracle APEX (directly through URL viz. http://someserver:7780 / pls/apex/f? p = 123:101)

  What kind of error is it?

  • HTTP error with an error like 404 code
  • Error on Web server with detailed description of the error (if so, check the newspapers of OSH for more information)

  What is the type of the OHS?

  • Oracle Application Server 10g
  • Oracle HTTP Server distributed with Oracle Database 11g

  Finally it is part of your question:

  When I connect to APEX http://xxxxxxx:7780/pls/apex / , I don't see any change in the user interface. Where is the 4.2.0.6 APEX version?

  What did you mean by that?

  • You receive the login for the old version screen
  • You receive a blank page

  I would like to you check the following things:

  • Check that the APEX_PUBLIC_USER account is unlocked. Please see section 3.5.5.2.1 on expiry of password in the Oracle 11 g database in https://docs.oracle.com/cd/E37097_01/install.42/e35123/otn_install.htm#BHAJHJAG
  • Check if you have copied the images properly after the upgrade. Reference: https://docs.oracle.com/cd/E37097_01/install.42/e35123/otn_install.htm#BHAJDGFJ
  • Check that you have the correct configuration for images settings, the database connection string, user name and password database. Reference: https://docs.oracle.com/cd/E37097_01/install.42/e35123/otn_install.htm#CHDHCBGI

• APEX 4.2.2 upgrade hanging but now reinstalled still get white screen

  Oracle DB 11 GR 1 material EA
  Linux RHEL 6.3
  APEX 4.1.1-> 4.2.2
  GlassFish 3.1.2
  APEX listener 1.1.4
  =============
  
  Tried to update my APEX of 4.1.1 to 4.2.2 and lost my session/connection of terminal. The result was that the upgrade was clinging to the status "REVALUATION".
  Decided to remove the APEX 4.1.1 and reinstall from zero APEX 4.2.2. No problems in the newspapers and the State now "VALID".
  Images copied to the Glassfish server - and even the database using @apxldimg.
  Problem:
  
  I think to connect at the APEX, but get a "blank" screen (web page). Still using 'old' APEX earpiece and modernize to 2.0.1.
  
  Any suggestions?

  Figured it out.
  =========
  When I initially copied the images I used (directories are anonymized below for security):

  rsync - number/home/images/home/glassfish/docroot/i /.

  and apparently it doesn't work or I had a typo in, because when I tried and then

  cp - rf/home/images / /home/glassfish/docroot/i / *.

  everything has come - no more blank screen.

• Apex 2 - white page loaded earpiece

  Hi all
  
  I installed the Apex 2 (2.0.0.354.17.05) earphone production on Glassfish 3.1.2.2, version 5. It's got deployed properly, that I followed all the steps in the installation and configuration guide. But when I enter the url: http://Server: 8080/apex, all I see is a blank page. I tried to add a second database, but using the url http://Server: 8080/apex/Zeno (the name of the database is zeno), I also see a blank page.
  
  There is no any logfiles is when I enter the above URL. In sql developer, I checked the log options, but newspapers inside the SQL Developer are empty, and Glassfish newspapers does not seem to have been a mistake somewhere.
  
  When I stop the service of Glassfish, there is no Apex listener to my database connection. When I start the service, three connections are made; If the db parameters should be good?
  
  Does anyone have an idea, what the problem?
  
  Kind regards
  Tom

  I just found the solution. It was with routing rules. Use the URL path as the routing rule type and routing full URL of the rule reference as http://example.com/apex/sales where /apex is the path to the context of the apex on example.com listener and sale is the name of the parameters in the settings of the connection URL. Diagram of restful services is optional.

  Now, using http://example.com/apex/sales you will be able to access the workspace login page and no empty page.

• Cannot restart APEX after reboot

  Hello

  First, are you able to connect to the database in SQL * more?

  Can you try to start the listener like this:

  -Dapex.home file does NOT reflect your oracle folder, but this is the place where the listener stores its cache and settings (and probably other things too)

• How can I access download old newspapers?

  I recently lost a hard drive with a large amount of data on it and seeks to re - download files. The hard drive with firefox is intact. The files I'm looking for come on until I recently deleted my download history. How can I download the old newspapers?

  Any help would be appreciated.

  In Firefox - {Ctrl + J} to open the downloads window. It's only "journal" of files downloaded through Firefox, and it doesn't go as far as the last time this list has been erased, or that the data was 'thrown '. Firefox does not keep a real text "log" of the downloads.

• Newspapers of LDAP data using entire disk?

  Hi all

  Last week, my Mac OS X 10.11.2 running Server 5.0.15 was dangerously near full and now he declare 'Zero bytes available.

  Using OmniDiskSweeper, I was able to identify about 21 000 files named log.0000000001 through log.0000021329 taking about 235 GB located at the following location:

  / private/var/db/openldap/data /.

  WOW! Something tells me that I have all that, especially since it is a stifling of the machine, but I thought I would ask here first:

  1. can I safely delete these files? Do I really need?

  2. How can I identify what is causing these logs to be created and stored? It is not normal or expected activity, is it?

  Thank you very much

  Willhaus

  Then, I moved and remove the vast majority of these files, because I don't see why I would need them, and the server keeps do new all few minutes or a few hours, so I'm having a lot of replacements soon enough.

  But still, can someone help me understand what is what in fact occur and how to stop it?

  Maybe it's just a coincidence, but I also noticed that there is an about 25 GB of files here:

  /private/var/db/OpenLDAP/migration/oldsystem.tar

  It was created on the same day 10/10/15, which comes from the grip of these files newspapers of thugs. Y at - it possibly a link there?

  I'm definitely not an expert when it comes to these things, so that any help would be welcome.

• HP Officejet Pro 8620: Auto prints Fax newspapers - when no Fax has been sent

  Several times now, my printer prints sheet Fax connects during the night.  I have not hooked to a phone line, or use the fax machine.  It prints 40 to 50 pages of newspapers only fax sheet at a time using usually upward all the paper in the tray.  It happens always in the night.  Is there some features need me to disable this option?  Any help is appreciated.

  Hi @antiquesbyadkin,

  I see by your post that the printer automatically prints a log of faxes. I would like to help you today. If this helps you to find a solution, please click on the button "" accept as Solution"" down below this message. If you want to say thanks for my effort to help, click on the 'Thumbs Up' to give me a Kudos.

  I checked the manual, for this model I don't see anyway to change the fax log. You must manually select the menu to print it. I also checked our laboratory model and could not find the settings to disable this feature.

  I want to erase on the log of faxes, which should already be empty because the printer is not used for faxing.

  1. in the Control Panel printer displays, touch and drag your finger across the screen, then
  Select Configuration.
  2. press on the configuration of the fax and then tap Tools Fax.
  3. press on the clear fax log.

  If you are setup for ePrint, it may be a sender who sends faxes over newspaper. To know for sure, I would say to set up the account to only allow that shippers. Go to hpconnected.com, click on devices, next to your name of the printer, select settings, then select admitted only shippers. (you can add senders individually) Test this out for a few days to see if it was the cause of this.

  I would say for updating the firmware of the printer, to see if that can help you if the problem persists. OJP8620_R1502A.zip

  Please let me know the results. Good day! Thank you.

  OK, so it's question, the problem persists in this two proven pitchers, Nova, Apex. Notification buttons (Tesla Launcher - Nova, Apex Apex notifier) are not at all. There is no record of the notification of any application connected in series to the top. This Launcher works fine on Samsung, Lg devices etc. So no matter what moderator or a Lenovo hard user can tell me it's me something wrong? All settings are correctly configured in phone set up and pitchers... so actually put something l? There is no way to see how many missed calls or sms or whats up, facebook etc. notification l have on Lenovo Vibe Z2 Pro. Launcher from Lenovo and the user interface of google work ok.

  Problem is now solved, the team fix the plugin to metrinova and tesla apk!

• Error when importing complete file with many newspapers

  Hello

  I came across an error when you try to import an entire folder containing 118 newspapers (total size 63 MB), created by and imported to Signal Express 2012 (version 6.0.0).

  After about 80 of them have been imported without any problem, error, indicated in the attached file, see.

  The journal other files can be opened one by one after will have been delivered to market there is apparently no problem with files.

  My path to the folder that contains the log files are 81 characters long. I also tried a shortest path with only 9 characters, but it did not help.

  Looks like it's a bug in SE. Is there a solution?

  Concerning

  Jocke

  It turned out to be a bug in SigX2012. SigX opened the TDMS file handle but could not close during the import. So when a loading 118 connects at some point, SigX reached the memory limit.

  As for SigX2012, we have a solution for you. Newspapers, by half and each folder contains 59 newspapers. Launch SigX and import logs folder, and then save the recording project and exit SigX. SigX to restart and load the project you just save and import the other journal folder. Let me know if it works on your side.

  Once again, thank you for reporting the bug to us.

• Key id of database of newspapers

  Hello

  I was instructed to take the newspapers of different testers and insert these log files in a central database.

  I was able to split the data I need to get out, but I have real problems with the creation of a key. Now, I've split the log files in 2 separate tables.

  1 table contains the main results (if it has the serial number, type of test, unit type, duration, start date/time and status)

  2nd table contains the details of tests were merged (cocacenated) with the pass / fail result.

  The two tables will be linked by this ID.

  I am trying to achieve on HeidiSQL (MySQL)

  I have installed ODBC for mysql and its related to the database.

  Here is the sample code im work off of, but I can't make it work either.

  

  However when I run this I just syntax errors.

  

  I did something stupid without realizing it?

  Kind regards

  Looks like VI made citing no automatic string identifiers. Try to add the names of columns that contain a space in square brackets.

  for example

  [Date of Test]
  

  If you can still change the definition of the table it was preferable however to avoid spaces in column names and other identifiers of databases. Use CamelCase as you did for SerialNumber or replace the space with an underscore character.
