• User access to the Apex

  Dear all,
  
  What is the 'user access' in the Apex. When I type:
  
  Select the username of all_users;
  
  I do not see users that I created at the Apex (I use Oracle XE). What I need is:
  
  I have a table by its name of 'Agents' and I need to let each officer sees its files only without displaying the records of others.
  
  Maybe have a look at this picture you would understand my request.

  Thanks in advance.

  I need to let each officer sees its files only without displaying the records of others

  In the agents table how do you store the user details (of the apex user who packed / "holds" the record)? In other words how can a record to identify the user, can you have a column where you insert these data, do you establish this apex or use a trigger?

• If you do not have such a column add a first

  ALTER table add Agents (record_owner VARCHAR2 (100))

• When you insert records into this table, set this column with v ('APP_USER') as a trigger or directly from the PLSQL process.

• Then change the report query to filter the records owned by this user

  Select * agents where record_owner =: APP_USER.

• To access large partitioned tables over a database link - traps?

  Hello
  
  We are in the middle of a business acquisition, and I have a question on the use of links to database access efficiently to large tables. There are two distinct geographical database instances, both on Oracle 10.2.0.5 sitting on Linux boxes.
  
  The main forum (PSHR) contains a PeopleSoft HR system and pays and is sitting in our data center.
  
  The secondary instance (HGPAY) runs a payroll application home grown and is in a different datacenter to PSHR.
  
  The requirement is to allow PeopleSoft (PSHR) to display data of payroll (one employee at a time) targeted to the secondary instance.
  
  For example in HGPAY
  
  CREATE TABLE MY_PAY_DATA AS
  SELECT TO_CHAR (A.RN, ' 00000000') 'EMP' - it is a figure 8 leading 0 unique identifier
  '20110' | TO_CHAR (B.RN) "PAY_PRD" - it is a format of exercise more than fifteen days in the year (01-27)
  C.SOME_KEY - it is the element of remuneration being considered - effectively randomly
  , 'XXXXXXXXXXXXXXXXX' "FILLER1.
  , 'XXXXXXXXXXXXXXXXX' "FILLER2".
  , 'XXXXXXXXXXXXXXXXX' "FILLER3".
  FROM (SELECT ROWNUM 'RN' FROM DUAL CONNECT BY LEVEL < = 300) has
  , (SELECT ROWNUM 'RN' FROM DUAL CONNECT BY LEVEL < = 3) B
  (SELECT TRUNC (ABS (DBMS_RANDOM. (Random())) 'SOME_KEY' FROM DUAL CONNECT BY LEVEL < = 300) C
  ORDER OF PAY_PRD, EMP
  
  HGPAY. MY_PAY_DATA is the range partitioned on EMP (approximately 300 employees by partition) and the list below partitioned on PAY_PRD (3 pay periods a secondary partition). I limited the above create statement to represent a sub-partition of data.
  Every employee generates an average of 300 lines in this table each pay period. The table has about 180 million lines and all fifteen days more.
  
  In PSHR
  
  CREATE VIEW PS_HG_PAY_DATA (MEP, PAY_PRD SOME_KEY FILLER1, FILLER2, FILLER3)
  AS SELECT EMP, PAY_PRD SOME_KEY FILLER1, FILLER2, MY_PAY_DATA@HGPAY FILLER3
  
  PeopleSoft would then generate SQL along the lines of
  
  SELECT * FROM PS_HG_PAY_DATA WHERE EMP = '00002561' AND PAY_PRD = '201025'
  
  The link between data centers where PSHR and HGPAY sit isn't the best in the world, but I expect dozens of hits per day rather than thousands, so I think that the link must have sufficient bandwidth to meet the requirements.
  
  I tried a quick test on two instances of size production test and it works because it presents the data, when I look at the plan of the explain command that I can see that the remote database is only presenting the relevant secondary partition on PSHR rather than the entire table. Until I get in the back with a "job well done" - y at - it a witch hunt that I am absent using dblink to access the partitioned tables of big?

  Yes, it's just. A lot of it depends on exactly what happens in different "oops" scenarios - you are, for example, just burn some CPU extra until someone comes to the DBA and says "my query is slow" or saturating the network has an impact on critical applications or long random queries prevent some maintenance operations of partition.

  In my mind, the simplest possible solution (assuming you are using a username that is fixed in the database link) would be to create a profile on HGPAY for user defined for the link of database that set a value LOGICAL_READS_PER_CALL which was large enough to handle any request '' reasonable '' and low enough to quickly kill any session that has tried to do something 'stupid '. Obviously, you have to define 'stupid' in your particular environment where the scope of a 'simple reconciliation report' is not defined. If there is no political problem and you can adjust the values of profile to the wire when you encounter new reports that slowly increase what is considered '' reasonable '' is probably the most straightforward approach. If you have to put in a change request to change the parameter which must be reviewed by the Control Board change at its next quarterly meeting with the outsourced DBA seller, on the other hand, you could turn a report by 30 minutes in 30 hours over 30 days. However, in an ideal world, this is where I would start.

  Becomes more complex, you can use the resource manager to kill applications running too long on the wall clock. Since the network will almost certainly the bottleneck, it is probably unlikely that the limitation of the CPU will do much good - probably you can saturate the network with a very small amount of CPU. Limitation in my mind of the network is an additional step in complexity according to the specifics of your situation and what you are competing with.

• Failed to create database link when the password has a special character

  I am trying to execute the following statement in sqlplus
  
  create alpha link database to connect to scott identified by tiger! using "db_alpha".
  
  Note that the password of the account has an exclamation mark inside. the command fails. I tried to put the password in quotation marks (') and double quotes (""). Working the double quotes, but then the link does not work properly.
  
  We are required to have a special character in our passwords... so, how can I get this special character in the password for the database link?

  I don't have two databases, so in my sol10 database I create two database links sol10@Darren2 and sol11@Darren2 both pointing to itself (back to sol10 database). That's why I use qualifiers link db. The two links you connect as a Darren2 user with password Tiger!. The global database name is sol10 and initialization of setting global_names = true. As you can see what global_name (sol10) corresponds to the name of the link in sol10@Darren2 db (again, the link name is sol10 and Darren2 is qualifying link) select vai db link works OK. But the sol11@Darren2 link fails because the name sol11 link does not match the name db global sol10. However, as soon as I change global_names false, sol11@Darren2 works fine. It will be useful.

• Why the data in my database disappears when I restart Tomcat?

  I have a DPL Berkeley DB database that I use for a Web application that is running under Tomcat. I can store data in the database and get it back, but when I restart Tomcat and the data have gone. In my view, that the problem is that the data is in memory, it is never written to disk, so it is not persistent across reboots. I think that this, because when I write the data to the database, the size of the files in the data files does not change.
  
  My database is not transactional, nor in writeback mode.
  
  What else could cause this problem? I'm completely stumped.

  If the environment/store is not transactional (you do not call setTransactional (true)), then the data can be sustainable only equal to 1) you call Environment.sync, 2) a control point is executed by the thread of checkpointer I background or your application, 3) you close the environment itself, that will make a control point.

  I suspect that you do not close the environment when you shut down your server.

  You can take a look at the writing transactional Applications. He described the durability more in detail.

• Remote access to the apex applications

  Hi all
  
  I I find a way to allow access to applications apex of remote machines in my local network. Local access works very well. I need allow users to access their customers-browser web applications by using the URL as http://lugao-pc:8282 / apex. I use Apex 4.1.1 in Oracle 11 g 2, using Embedded PL/SQL gateway
  
  I've seen other posts that say remote HTTP connection allow the database using DBMS_XDB EXEC. SETLISTENERLOCALACCESS (false); in SQLPlus as SYSDBA. But that doesn't did not help me. I think it is because I use the PL/SQL no Oracle HTTP Server gateway. If am not wrong how do I allow remote access using existing installation?
  
  Concerning
  
  Sadik

  Hello

  You must run DBMS_XDB EXEC. SETLISTENERLOCALACCESS (FALSE); If you use Embed PL/SQL gateway.
  If you want to use another HTTP server then it is useless.

  Did you try to turn your firewall server to and see works the connection then?

  Kind regards

• Access to the applications of Builder Websheets

  Hello

  I want to give the developer role to one of our users, so it can develop a specific websheet of applications

  Problem is this setting a user as a developer still requires access to or another builder or sql application workshop

  I wouldn't give any of that, because they could access the application builder page and remove applications without any problem

  In the Web application sheet there is a button Builder, is possible to hide it somehow?

  I don't see any possibility to do, I tried with the chrome, definition of the element plugin: visibility: hidden and it works, only problem, is that I have no idea where to add this attribute to make it permanent

  Thank you!

  Hello

  To allow a developer to 'create' applications they need the privilege of Application Builder.

  I'm no expert with Websheets, but I'm sure that all 'development' is from the front-end of the application, so the user does not require access to the APEX server.

  If you have two options:

  (1) you will need configure a new application Websheet to this person whenever they need to reapply; OR

  (2) create a new area of work/drawing away applications, you don't want him to have access to and they have access to full development.

• Copy the APEX Application

  Hello people:

  Oracle Database 11 g Express Edition version 11.2

  Request Express 4.0.2.00.08

  I have a question for you.  I developed a simple application for a Department within my organisation:

  8 pages (no application process, process page 12)

  2 triggers

  2 sequences

  2 tables

  Other departments within my body as the application so they would like their own "copy".  Because of the type of information entered in the application, I can't have all the applications use 1 (of course I can but I need to create a somewhat complex authorisation schemes and I'd rather not go that route);

  
  

  Now, finally the question:

  
  

  Is there a way to the APEX to copy an application and recreate all the components (table, triggers, etc) from the new table names?  APEX makes it definitely easy to make a copy of an application, but I then go through the copy with a fine comb to change all references to the old names of table and replace it with new table names.

  
  

  Suggestions?  Comments?  I thank all members of this community of Oracle, because you communicate knowledge where it is lacking...

  Any suggestions?  Comments?  I appreciate everyone in this community of Oracle, as share you information where it is lacking...

  If it becomes a business tier application, it must be generated using the level technology company, such as the authorisation schemes, VPD to the multi-tenant data to be stored in the same tables and sturdy PL/SQL API for the maintenance of the data rather than the process Assistant APEX.

  Authorisation schemes are of no use in restricting access to the data, they are used to control access to the APEX application components. You can use authorization to control if a user sees a report from the region, but not the rows that are displayed in the report. To do this you must use VPD or views (note that separate sets of tables are not even considered an option).

  If all departments use, how long before that some top-level executive wants to have access to the data for each of them? How easy it will be to predict that, when the data is distributed on several tables?

  That said, SPV is not available in the XE, and the fact that you use it means that you are unlikely to be able to switch to Enterprise Edition to get it.

  My recommendation would be to rebuild the application using a set of tables, the views that restrict access to data by the Department and the generation of reports and PL/SQL with API packages manage data.

• How to start and stop the APEX?

  Hi all! I am new to this forum and APEX too...

  We are runing (Version: Application Express 4.1.1.00.23)

  I need to reboot the server.

  How can I stop APEX graciously and start back after? Thank you!

  Kind regards

  Ghyslain salvation,

  to reinforce what Mike says. Apex is a database and, with the exception of the HTTP server application, runs entirely on the database. (Note with EPG, its all in the database) It contained in the users/schemas database and built items of data such as tables and PL/SQL packages. If the server that is running the Oracle database in which the Apex is installed needs to be restarted, the database must be stopped, which stops indeed Apex. If the HTTP server is also running on this server (ESS or earpiece of the Apex) then this should be stop as well.

  Of course, if your desire is not to stop the database, but to deny the user access to the Apex, perhaps for purposes of maintenance of database, then this can be done by stopping the HTTP server or by stopping the EPG.

  I hope it is clear now.

• Setting up the environment of the APEX

  Hello
  
  I have a series of questions to establish access to the APEX. The ability to use OSH has been discounted. We want to use a separate apache and struggling to configure mod_plsql. The license for mod_plsql indicates that it should not be used in this way. There is a valid alternative?
  
  Kind regards

  It seems that in a first time listener of the Apex has been dismissed by licensing issues. I did research on this subject, but I'm a bit confused. If Apex earphone using WebLogic, is that I have to WebLogic server license? As I read, Apex license includes WebLogic, where we don't need license Weblogic and it's free, it's okay?

  The apex is free. It works on XE, which is also free.
  ApexListener is free.
  WebLogic (WLS) is one of the containers in which you can deploy ApexListener Oracle supported JEE. WLS is a licensed product.
  The other supported Oracle JEE containers are Glassfish (licensed) and OC4J. ApexListener can also be run in stand-alone mode, although this is not recommended for Production environments.

  ApexListerner also runs on other containers not - supported Oracle JEE as community Glassfish (Open Source) server, Tomcat, etc. By failure to load this means that you cannot trigger a SR on Oracle for these, you will need to depend on this forum and the consultants if you enter certain issues.

  See you soon,.

• Problem: Access to the database.

  Hello.

  I have a problem with my NI Multisim 12 (Student Edition). It installs correctly and correct registry also, but when I run the program it displays these messages

  "Problem: access to the database."

  The data are not available. Functions using the database will be unavailable. »

  And similarly for the database and database user.

  In the end, it shows this message:

  "Multisim has detected that the main database is not on the current user. Reinstall the program from the original media. »

  I have the original of 2012 Labview and Multisim 11 (from a myDaq) media.
  After that, I can place any component because the program cannot access data bases. I can open previous designs, but it is not properly simulate.

  I am the only user of the computer, and I am the administrator.
  I have a 64-bit Win7 with Core 2Duo 3 GHz.
  I recently installed Labview 2012, which includes this software, so I uninstalled previous Multisim.

  On the same computer without any problem, I used Mutisim 11. I tried to reinstall Mutisim 11, Mutisim 12, delete windows registry, remove files after installation, giving permission for all files and nothing works. Whenever I have reinstall Multisim it displays these messages.

  Please, help me!
  Any help, or anyone with this problem or similar, let me know also.

  Thank you!!!

  Once again, many thanks. I solved the problem just now. I need to change the windows registry, following the instructions in the link. Thank you
