  A someone has encountered this problem and solved?

  Thanks in advance!

  Hello

  you are using IBM AIX PowerHA for your database (active/passive) configuration. then you just install the binaries 'once' on one of the nodes. then coordinate with your operating system administrator to configure the fail the test scenarios.

  for your question. before you start the database, make sure that there are no "orphaned" oracle process using the UNIX grep command:

  $ ps - ef | grep ora

  Kill the oracle of the hanging of the process to release the lock on the database file handle:

  $ kill-9

  I hope this helps.

  Kind regards

• Locking before backup database

  I wonder if there is a logic to the locking of the database or the tables especially before I perform a full backup critical of my Oracle 11 g R2 (11.2.0.3) database using RMAN utility? I followed using this forum and the manual to configure my FRA RMAN and settings, but that does not explain the documentation makes sense / theory which I have of course not. Should I or you RDBMS veterans recommend that I have somehow freeze the database diagram or table to prevent data being deleted / changed / or added while my RMAN utility backup my forum?
  
  How are they managing guys (not scheduled) backup time if you want to make sure that no change is made before save you?

• short of space locks roll FORWARD the database

  Hi all
  
  My database RAC 11 GR 2 running on both nodes RH5.7 got locked. I tell the cause the disk space RECOVERY satiety than the execution of what the ASMCA shows that the entire roll FORWARD is used (40 GB!)
  
  Furthermore, I try to access the database via sqlplus, I get ORA-00257 (http://ora-00257.ora-code.com/) that mentions
  
  "The most likely cause of this message, it is that the destination device is out of space to store the redo log file.

  No, it is the opposite: Oracle instance blocked any new database entry to be recoverable.

  And as we cannot access, we cannot remove these logs?

  Even if archive destination is stored in ASM you can access (for example with the utility asmcmd command line interface).

  What you need to do is:
  1 backup archived redo logs
  2. Remove archived redo logs that have been saved.

  For example if you use RMAN, you can try

  backup archivelog all delete input;
  

• Error 2147024882 in the database

  Good afternoon.

  I try through OR DIAdem 2011 analyze vibration signals, the problems is that the database is in Microsoft Access and all the data were inserted as a string. I therefore did a VI that convert all data to a numeric value and generates a file of PDM DIAdem.

  

  This VI works perfectly with small databases, the major problem is that the files that I need to analyze are 500 MB to 700 MB and when I insert the database DB tools select data VI gives me error 2147024882, I'm guessing that locks the size of the files.

  So anyway is to insert all these data without fracture of my database?

  Thanks and regards.

  Thanks for the help, but I managed to solve the problem through tiara, create a digital channel and by copying bites generated in this new channel and DIAdema automatically converted to digital data.

  You cannot copy directly, but you can save only data file with rman "backup datafile 42. However, the RCS in the header of the data file would be different now, and you cannot recover.

  You said in one of the message that the file without a NAME no longer exists? You rename it using 'alter database rename file '?

  You can use:

  ALTER database create datafile 42 as ' / home/oraprod/PROD/data/a_txn_ind10.dbf';

  I don't have the right backup to get it restored. While we have of any other alternative way to present this request to normal.

  Sure it's not an orphan process esssvr or something hold you on files by creating a lock.

  A simple way to find out is to stop all applications and check if you have a current esssvr process, if you kill the process and then try and start the application.

  See you soon

• Connection.setAutoCommit (false); She creates a transaction next to the database?

  Thank you!

  Non - autocommit affecting false does NOT create a transaction.

  You can EASILY search the Web for definitions of terms such as the transaction, logon session.

  The Java tutorials has a track for "aid Operations."

  https://docs.Oracle.com/javase/tutorial/JDBC/basics/transactions.html

  Turn off autocommit Mode

  When a connection is created, it is in autocommit mode. This means that each SQL statement is treated as a transaction and is automatically committed right after his execution. (To be more precise, the default is for a SQL statement to be engaged when it is finished, not when it is executed. A statement is completed when all its result sets and update counts were recovered. In almost all cases, however, a statement is completed and therefore committed, just after his execution.)

  How to allow two or more instructions which lie in a transaction is to disable auto-commit mode. This is illustrated in the following code, where con is an active connection:

  on.setAutoCommit(false);
  

  The Java API tells you what a 'link'

  Connection (Java SE 7 platform)

  A connection (session), with a specific database. The SQL statements are executed and results are returned as part of a connection.

  See where it says "connection (session)?

  And the Oracle documentation can discuss those from the point of view of DB

  https://docs.Oracle.com/database/121/CNCPT/Transact.htm#CNCPT117

  Introduction to Transactions

  A transaction is a logical, Atomic work unit that contains one or more SQL statements. A transaction includes the SQL statements so that they are all committed, which means they are applied to the database, or all canceled, which means that they are cancelled from the database. Oracle database assigns to each transaction a unique identifier called transaction ID.

  Oracle transactions obey the basic properties of a database transaction, known as ACID properties. ACID is an acronym for the following:

  . . .

  After the end of a transaction, the next executable SQL statement automatically starts the following transaction.

  . . .

  The Oracle documentation also discuss when a transaction begins - which may be different from another database

  http://docs.Oracle.com/database/121/SQLRF/statements_10005.htm#SQLRF01705

  Use of the SET TRANSACTION statement to establish the current transaction in read-only or read-write, to establish its isolation level, assign it to a specified rollback segment or type a name for the transaction.

  A transaction is implicitly starts with any operation that requires a TX lock:

  • When a statement that changes data are issued
  • When a SELECT ... FOR UPDATE instruction is emitted
  • When a transaction is explicitly started with one SET TRANSACTION statement or the DBMS_TRANSACTION package

• Locking under the FORM of Oracle

  Dear friends,

  We have a problem with the FORMS and the table locking if multiple users access the same custom FORM.

  There are 3 blocks in my FORM

  1 header (pointing to the table of the database header) - the user enters the data...

  2 lines ((pointing to the table of database lines)) - user enters data

  3 results (pointing to the Global Temp Table) - based on the information header and row in the table. Result block will be filled with data.

  Not sure how blockages that happened on the tables... If a user session is active more than an hour, then for all the users and lines table locks... Other users are not able to access anythnig on the FORM.

  The header has 2 columns - customer number and customer name. When the user enters the name of the customer... We use COMMIT (not the COMMIT_FORM)

  Lines has 3 columns - Item name, warehouse, and quantity - when the user enters the data for the quantity, then we are using the VALIDATION (not the COMMIT_FORM) and calling a package to poulate data in the Global Temp tables.

  Note:-do not know what the correct community to address this issue.

  Kind regards

  Bala

  Hello

  Yes, it must be displayed in one of the forms.

  In any case, what are the properties of the first two blocks database?

  Kind regards

• Do not lock - automate the deletion of backups RMAN old day after a success

  Hi all

  Admin: Do not lock this thread. I moved here the database instance based on the suggestion of another Member, and the question to this forum. If you want to lock a thread, lock one in the forum of the database, not this one.

  I am looking for a way to automate the deletion of backups RMAN old days only after the occurrence of a success. At the present time, I have daily backups of L0 via crontab, and I need to create a script that can tell if a successful backup is done, then delete the old L0 if it has. Any suggestions on how to start? I'm stuck in code to see if a successful backup has been performed.

  Oracle 11.2.0.3

  Exadata (4 nodes)

  Linux 5.10

  * a from database forum

  A backup is completed when the backup command is complete.

  You have two 'blocks execution' in your rman script.

  Put the DELETE OBSOLETE between the end of the last execution block and EXIT:

  OUTPUT CHANNEL fs1b;
  OUTPUT CHANNEL fs2b;
  OUTPUT CHANNEL fs3b;
  CHANNEL fs4b;
  CHANNEL fs5b;
  CHANNEL fs6b;
  CHANNEL fs7b;
  CHANNEL fs8b;

  }

  remove the backup noprompt obsolete;
  "exit";

  You also want to do some other household:

  cross-checking of backup;

  delete expired backup noprompt.

  overlap archivelog all;

  delete noprompt expired archivelog all;

• Planning level 11.1.2.1 in 11.1.2.3.5 - updating of the database is not updated every custom on some Member attributes

  Us are currently working on improving our environment to 11.1.2.1 11.1.2.3.5, but have you encountered a problem with one of our applications, and only on one of the cubes in the application. When we perform a refresh of the planning database, it initially stripped of some members of the attributes, custom and is now refusing (Finally, not directly) to update on that specific cube. The other cubes in the same application, I can see the custom attributes, update correctly.

  The cube itself is not locked on the side of essbase, prevents the updates and the updating of the database of planning indicates he managed. I spent reviewing the essbase application log and planning0 journal, noting none of which seems to indicate a problem with the refresh or out of the ordinary.

  I am able to edit the cube directly via EAS and on the updating of the database, the changes are deleted (if I add an attribute) or the Member is restored (if I remove the Member), but still, no custom attributes.

  It is unfortunately the case at some 700 members of 5,000 members in one of our dimensions and only in a cube so that a single application, but we hit an obstacle for what might be the cause. What is happening in the our QA Dev environments, but I expect that since one is one migration on the other. Step moved to production yet because this (among a few other things) continues our implementation.

  If anyone can lend a thought on what could be the cause or the paths to understand where we can't look to fix this? I definitely appreciate all the help that can be done.

  Thank you

  Jonathan

  A solution to the problem, but not sure about the cause. By deletng the cube that has problems and performing a database update subsequently, we are now able to see the cube with the appropriate attributes. It would seem that we had problems with our cube Essbase itself rather than on the side of planning.

  My suspicion is that it might have been caused by our Essbase upgrade are out of sync from the upgrade of planning during the updating of the original database after the start of the process to upgrade (11.1.2.3.5 for planning vs 11.1.2.3 for Essbase). While I am not sure of the cause, I am sure the solution so feeling good go ahead now.

  John - I appreciate all the help and insight along the way, as it has helped us reach this point of the solution.

  Thank you

  Jonathan

• Involved in the creation of the database in PeopleSoft FSCM

  Hi all

  
  I am creating the peoplesoft FSCM 9.2.I for database have followed the steps outlined in the document to install oracle (peopleTools version 8.54). I had the problem when I try to connect like application designer "EBU Invalid ID and password for sign. I can able to connect using Data Mover SYSADM/SYSADM.

  I have run the grant.sql query too. Please tell how to solve these errors. I created the db twice, but no luck, I got the same problem.

  I doubt that there is any some Userid for FSCM (Say VP1),because I have procedure step by step the document they say for user ID FSCM is VP1. But in dbowner.sql it look like as follows

  Please help resolve this error. Sorry if I misunderstood any procedure.

  I think you need some basic knowledge of first before going any further in the installation.

  SYSADM is the owner of the user Oracle Peoplesoft objects (tables, views,...), you can connect to SGD but will be "bootstrap" mode only. It cannot be used for AppDesigner connection.

  PS is a locked user account Oracle hosting only arrays of connection security. It cannot be used for any connection of DMS or AppDesigner application.

  VP1 is a user of the application. It cannot be used for Oracle, only DMS/AppDesigner connection. If you turn on all counts with the default password of the screenshot that you has shown, it should be able to connect to the application.

  Server application ID is used to manage the application server, defined in the configuration file of the application server.

  Sorry to move, but you really must go through the documentation official http://docs.oracle.com/cd/E55418_01/psft/html/docset.html

• What update statement is sent to the database?

  In several pages, I use the Apex line (DML) 4.2 automatic treatment processes. If I do an update of a record, which are columns in the update statement? All columns, only the displayed, only the columns changed, also the PK column?

  As far as I can see now all the columns that are displayed are updated, also the PK, which is display only.

  I ask this, because when the PK is updated (not changed is screen only) all tables in my 75 cases, where this PK is used as FK, will get a lock.

  I did some tests and find out that indeed the Apex is updating all the columns used in the elements by Type of Source is the database column. Even if this item is display only, read-only, etc.!

  My solution now, to prevent the locks, is the following:

  Automated line Fetch:

  Primary key column value containing point: Pxx_ID

  ID of the primary key column: (this is the primary key)

  Pxx_ID (display only, hidden or read-only)

  Source: only when the current value in session state is set to zero

  Source type: static assignment<-->

  Source of value or expression:

  Treatment of automatic line (DML)

  Primary key column value containing point: Pxx_ID

  Primary key column: ID

• Cannot answer your request because the updating of the database

  I created a user in Services shared and then assigned to a group. After that, I went to the workspace in the ahead mode to manage security filters, the user does not appear and when I try to "create" an existing user, an error appears: could not complete your request because the updating of the database

  I do not turn any updating in the database and my EAS shows nothing. What could happen? It's Hyperion Planning 11.1.1.3

  Kind regards

  If an update of the planning is certainly not executed then maybe there is still a lock to indicate that an update is running, you can try to run the utility hspunlockapp - unlocking Applications

  See you soon
