• Resume it AGAIN APPLY: differences of 10g and 11g

  Versions > 10.2, 11.2
  OS > Solaris
  
  I have a question about step 4 below.
  In 10g and 11g versions for a physical Standby DB, you
  
  Step 1.
  Mount the DB using

  startup nomount;  
  alter database mount ;

  Step 2. Start using it to apply

  alter database recover managed standby database disconnect from session;

  Step 3. Open the DB to help ensure

  recover managed standby database cancel; -- stop the redo apply
  alter database open ; 

  Step 4. Resume it AGAIN APPLY

  alter database recover managed standby database using current logfile disconnect ;

  At this point (after step 4), version 10.2, the standby DB goes back to fashion to Mount , but DB 11.2 remains Open for READ ONLY queries because of the ACTIVE DATAGUARD feature. Am I wrong?

  Yes, you are right.

  In 10g, there is no active dataguard option (application of redo is not possible when the database is open). Application of roll forward is only possible when the backup database is in the editing phase. When the database is opened in read-only, the application mode of archive is not possible. In order to execute queries against database tables, a physical standby database, he had to stop the log apply and open the database in read-only mode. This means that the log files are waiting for this period and should be applied once the database is returned to the managed recovery mode.

  11 g, this isn't the case. It allows users to have read-only access to the pending physical databases. This option gives continuous customers the flexibility to run queries to the database physical standby, while log shipping and apply its work. The application archive is possible even when the database is open read-only. This option is called Active Dataguard (Oracle, high availability). To do this, the steps you have mentioned are perfect. It's the advantage in 11g.

• Replicate between 10g and 11g?

  Is it possible to have a schedule of process and the spread of capture on an Oracle 11 g server, and changes are sent to and applied on an Oracle 10 g 2 Server?
  
  What the inverse (source is 10 gr 2 and destination is 11g)?
  
  I can't find Oracle statements on the question if any of these are supported or not.
  
  Thank you

  I assume you mean with the flow rather than, say, materialized views for replication. If this is the case, Yes, you can use the workflow to replicate data between different versions of the database. You can be limited using the workflow features that were available in the lower version - flow added the ability to manage data 11 g transparent encryption, for example - but except that it generally works very well.

• Connection by level: is there a difference between 10g and 9i?

  Hello
  
  When I run the following query

   Select level from dual connect by level <= 2 

  using Oracle10g Release2 database, I have a set of two lines:

  1
  2

  .
  But when I run the same query by using Oracle 9i database, I have an a single row result set:

  1

  .
  Please, help me understand why this difference?
  Thank you.

  Yes, there is. In the earlier versions as 9i, you must use see online:

  select  *
    from  (
           select  level
             from  dual
             connect by level <= 2

• Upgrade to DB 10g and 11g

  Hi guys,.
  
  Current version: 10.2.0.5
  Target Version: 11.2.x.x
  
  I intend to improve my DB from 10g to 11g.
  Before the actual upgrade, I can create a test 11 g environment.
  
  I've read a few articles and understand the following concepts
  1 create a set of tuning in current 10 g to capture plan and the performance of the sql execution statistics
  2 export the setting of 10 g and 11 g SQL import base
  3 export all data to 10 g and 11 g
  4 to 11 g database, consider whether there is a best execution plan and accept
  
  For my scenario here, my test 11g environment is not all applications server conneecting to it.
  For my 11g generate other plans, the sql should be run at least once in 11g. As there could be a number of SQLs captured in the tuning set, how I run everything manually (via sql * more) because I did not have a request to call him?
  
  In fact, my main goal here is to compare the execution between 10g and 11g plan. Already from 9i and 10 g, I have actually generate version manually sql execution plan and compare manually.

• C2664 errors after the upgrade of client db 10g and 11g

  Hi, after upgrading customer db 10g and 11g, the compiler gave errors error C2664:

  The same code was compiled correctly when you use the db 10g client. I know that I can easily correct this error by changing the code, but there is more than a sqlglm used instructions. I'm looking for a way that will solve the problem by changing the settings of the compiler.

  Hello

  There is a change between 10g and 11g. It is described in "Oracle 11g Pro * C nsqlprep Sqlglm issues [ID 860382.1]". The document, you can find on Metalink, aka Oracle Support.

• Difference between AL32UTF8 and UTF8

  Hello

  Our current database version is 10g with CHARSET = UTF8 to support Greek characters. However, the customer wants to switch to 11g (11.2.0.4.0) and the database of test created with CHARSET = AL32UTF8.

  Up to now to insert Greek characters, we have been offering script mentioning set NLS_LANG = AMERICAN_AMERICA. UTF8 and he has been inserting Greek characters correctly. However, it does not work with the new machine. If this setting, execution of the script gives error for the Greek characters "quoted string not properly done".

  
  

  I have two questions here:

  
  

  (1) is there a difference between UTF8 and AL32UTF8?

  (2) settings NLS_LANG works on character set of database right? What setting I put for NLS_LANG allowing to insert Greek characters or script windows or linux machine to run?

  
  

  Thanks in advance.
  

  Hello

  Answered below:

  -Oracle UTF8 is Unicode 3.0 revision in 8.1.7 and upward. AL32UTF8 is updated with Unicode versions in each major release, Oracle RDBMS 12.1 it is updated to Unicode 6.1,

  Apart from the difference in Unicode version the "big difference" between UTF8 and AL32UTF8 AL32UTF8 has build in support for "Additional characters", which are coded using "Surrogate pairs" (also wrongly called ' surrogate characters"'").

  Oracle UTF8 (Unicode 3.0) stores additional characters in the form of 2 characters, for a total of 6 bytes, using "modified UTF-8" instead of the "standard UTF - 8"(implemented in Oracle 9.2 and upward using AL32UTF8) 4 bytes for an extra character.

  This "modified UTF-8' is also called CESU-8 .

  Practically, this means that in 99% of UTF8 and AL32UTF8 data are the same for * storage * data. Only the additional characters differ in bytes/codes stored between UTF8 and AL32UTF8.

  -the necessary parameters are:

  LANG = el_gr. UTF8

  LC_ALL = el_GR.utf8

  NLS_LANG = 'GREEK_GREECE. AL32UTF8.

• Difference between FYI and Notification

  Hi all

  Sorry for the dummy question, but I'm a newbie BPM/BPMN and try to understand better what I use for my modeling process.

  Could you please explain to me the difference between the FYI and Notification? When it is better to use?

  Asked me to send an e-mail notification to users just to let them know where the process is, no manual action is required and the process must continue without interruption.

  Thanks for any help.

  Fairlie

  Hi Fairlie,

  Here is a tool of 2 page that lists all the different activities in BPMN, gateways and Oracle 11g and 12 c BPM events and what they serve each to- https://blogs.oracle.com/soacommunity/entry/bpm_poster_for_bpm_suite

  In your use case where you want to send an email to someone, and no manual intervention is required, use the Notification activity.

  News is an Interactive activity and causes a work item instance appear in the Inbox an end user in the workspace.  The difference between this and other types of interactive activities is that the work item instance does not stop at this activity in the process, but instead continues on the next activity in the process.

  A Notification activity is an automatic activity which does not create an instance of work item in an Inbox in the workspace, but rather sends a message of electronic mail, instant messaging, SMS or voice.

  When the work item instances reach these two activities, they do not stop and continue them automatically the next activity in the process.

• 10g and 11g

  Hello
  
  I read the various messages about Discoverer 10 g and 11 g upgrade.
  
  No matter who would be able to tell me the General problems that exist that we must be aware of if we improve to 11g?
  
  Thank you.
  
  Leah

  Hi LEA
  I see no major problems that would prevent you from upgrading to 10g and 11g.

  The server underlying application changes to OAS for Weblogic, but put except that you won't see any changes. Certainly more and Viewer function similarly as Admin and office. Even the iitself EUL is 100% compatible between the two. You mind I advise to use a 11g database.

  The tricky part is to understand how to install discoverer 11g and then having someone who can learn to manage the discoverer using Weblogic.

  From the point of view of the end-user, everything will be fine. In fact, in my opinion discoverer 11g works faster than 10g, probably because Weblogic manages web stuff better than the old OAS.

  Hope this helps
  Best wishes

• difference between BYTE and CHAR

  Hi all
  
  Oracle, as in syntax below, what is the difference between BYTE and CHAR used as size data type for the column NAME:
  
  CREATE THE CUSTOMER TABLE
  (
  NAME VARCHAR2 (11 BYTE),
  CUSTOMER_ID NUMBER
  )
  
  and
  
  CREATE THE CUSTOMER TABLE
  (
  NAME VARCHAR2 (11 CHAR),- or even VARCHAR2 (11)
  CUSTOMER_ID NUMBER
  )
  
  
  
  Rgds,
  PC

  First - do not use reserved words for column (NAME).

  If the database character set is UTF-8, which I believe is the default value in the recent version of Oracle. In this case, some characters take more than 1 byte to store in the database.

  If you set the field as VARCHAR2 (11 BYTE), Oracle will allocate 11 bytes for storage, but you can not actually be able to store 11 characters in the field, because some of them take more than one byte to store, for example, non-English characters.

  By setting the field as VARCHAR2 (11 CHAR) you tell Oracle to allocate enough space to store 11 characters, regardless of the number of bytes it takes to save each of them. I think that in Oracle 10g, 3 bytes per character were used.

  Kind regards

  Robert.

• Difference between 'Reload' and "Reload (Override Cache)"?

  Https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly#w_navigation, what is the difference between 'Reload' and "Reload (Override Cache)"? What makes "ignore cache"?

  Reloading Web pages and cache bypass aims to obtain a new copy of perhaps obsolete or damaged files currently stored in the disk cache.
  You can do it like the first attempt if a normal charging does not seem to provide a version of a Web site or if you are having problems with a Web site otherwise.

  We usually have advice that if you have questions:

  Reload Web pages and ignore the cache to refresh potentially stale or corrupt.

  • Hold down the SHIFT key and click the Reload button
  • Press 'Ctrl + F5' or 'Ctrl + Shift + R' (Windows, Linux)
  • Press 'Command + shift + R' (Mac)

  Clear the cache and delete cookies only from Web sites that cause problems.
  "Clear the Cache":

  • Firefox/tools > Options > advanced > network > content caching Web: 'clear now '.

  'Delete Cookies' sites causing problems:

  • Firefox/tools > Options > privacy > "Use the custom settings for history" > Cookies: "show the Cookies".

  Start Firefox in Safe Mode to check if an extension or theme (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problems.
