• Use of the database.

  Hello friends,

  I use a static database in my application.

  I don't have to create the database.

  I have a database that I put in my code and use it from there.

  So it is possible to do the same thing or should I create in SD card?

  I don't want to create database.

  Kind regards

  Unfortunately, SQLite works only from a database on a SD card or the "internal memory".  It does no memory on the device, or an asset provided with the application.  I'm sorry.

• Check the installed oracle components are actually used in the database

  I got a new database I have to optimize. So I think to delete some installed components that I think are not be used somehow in the database (IE procedures calls etc.). I see a whole bunch of components as "ODD", 'ORDIM', which I think are not used, but previous DBAs have installed them. So, is it possible to make sure that no part of the database are actually using these components so that I can remove these components. Also, what are your expert comments on it?

  Is it a production or a development environment? If an object is not used then this isn't necessarily a problem (performance wise) unless it is either cluttering up your dictionary or raising concerns regarding the consumption of unnecessary space. Personally, I would recommend that it is preferable to resolve what is to be used / taken of resources. It is maybe once a year report or a few old utility out once a year, the best monitoring, why those things are there.

  If you go down the road of a fall, rather than drop anything immediately block accounts for an agreed period to ensure that the scheme is not used & check all references other schemas of objects in the schema that you intend to drop, potentially of audit to check if they are being called by other patterns / verification dba_dependencies between schemas and objects using a hierarchical query to check the sub-levels.

  There are also quite a few standard Oracle components that are installed by default that have interdependencies and not necessarily be used in the dictionary (control dba_features_usage_statistics)

• How to check if utl_file was used in the database with the n ° / limited audit

  How can you check the database to see if any user has used the UTL_FILE pacakge?
  
  Thank you

  Another angle based priv study's directory objects. Read and write access to a directory object is necessary so UTL_FILE work. If some patterns have a write access to the directory objects, can create files.

  A schema that has the priv to create any directory has full access to create any necessary directory object.

  This, along with the methods suggested above, will restrict just what patterns have code and the privs required to use UTL_FILE successfully.

  If the code has been dynamic PL/SQL (an anonymous block), then who does identify actual code executed UTL_FILE, very difficult.

• Identify a tablespace that is not used in the database

  Hello
  
  How to find the tablespace that is not assigned to any user? Note that I have a table partition in which there is table space where the records will be placed in the future based on the requirement on this partition table. I gave the unlimited tablespace on these tablespace privilege for the user. How to find storage space that is not used at any time in the database?

  According to my understanding of your question

  To check the quota on the tablespace use query below:

  SELECT * FROM dba_ts_quotas WHERE username = "XXXX";

  to check the default tablespace use the following query:

  Select USER_USERS from dba_users where username = 'XXXX '.

  How to find storage space that is not used at any time in the database?

  Use view dba_data_files for space used for the tablespace.

  I hope this help you

• Synonym does public get used by the database engine in the schema of the owner?

  I have database public synonym 'P' and "S.P" table (in the "S" pattern).
  If my article references select array/object 'P' (without prefix-schema for the table), then there is no reference to the table ("S.P') or that it references a synonym ("P")?
  I understand that if my select query is executed in the session/connection made with schema/user "S", then the database engine does not at all synonymous, it will immediately table 'S.P. Is this right?
  Can you just confirm my understanding, maybe I'm wrong.
  
  (Oracle 10g, Windows OS)

  Fix. There is a certain order regarding name resolution.

  If I remember correctly then it searches first for the current schema objects (tables, views, procedures, etc.), then for private synonyms, then public synonyms.

  I get a bit more complex if you have a schema that is also the name of a package for example.

• How to check the database is created in the database of node 2 RAC

  Hi all
  
  Please allow questions maybe too obvious. I'm not familiar with RAC and ASM.

  2 built nodes on Linux 6.1 Windows 64-bit virtual machine.
  11.2.0.3 software grid & database.
  One of DB name is demo
  Node1 (demo1)
  Node2 (demo2)
  
  
  1. I installed the 11.2.0.3 grid software and set up ASM with her. The installation seems to succeed.
  
  I am able to use view state using crsctl (see the log)
  
  2. I installed the database software and you want to create a database (demo) by default. the software from 95%, but not able to realized the dbca.
  
  I see that the asm_pmon is running, but not able to see the process of demo db. I think at this point, I don't have my demo of database has been created yet.
  
  Yes, question
  1: is the database created?
  2. I try to use dbca to create my demo db, but at the stage of creation of the 'copy of the database files' - she complaint ORA-03114: not connected to ORACLE
  ???? What? What oracle server trying to connect?
  3. If the database is created, how to start the database, in particular it has 2 instances (demo1 and demo2)?
  
  Please advise!

  1. What is sure, is that your database is not registered in OCR because there are missing elements in crsctl stat res t exit for database instances.
  2. default DBCA trying to restore an RMAN backup to create a database. DBCA probably also try to connect to the new instance of the database to run scripts.
  3. you must use:

  srvctl start database -d demo
  

  This should start all database instances.

  But first try to check the DBCA logs that should be under $ORACLE_HOME/cfgtoollogs/dbca and to correct related errors.

• Not used in the database tablespace

  Hello
  
  I want to find the list of the tablespace in my database which is not used at any time. I have listed below the scenarios where I must avoid these tablespace
  
  1. I have a tablespaces in my database in which my application creates indexes at runtime and it falls. I need avoid these tablespace.
  2. each user can have a separate UNTOTABLESPACE. I need avoid these tablespace in my query.
  
  I use the query now to find the list of the tablespace that is not in my database below. But my query below does not satisfy the two conditions above.
  
  SELECT NAME UNUSED_TABLESPACE
  V $ tablespace
  WHERE NAME NOT IN (SELECT USER_USERS
  FROM dba_users)
  AND NAME NOT IN ('UNDOTBS1")
  AND NAME NOT IN (SELECT tablespace_name
  OF dba_ts_quotas)
  AND NAME NOT IN (SELECT tablespace_name

  AND NAME NOT IN (SELECT temporary_tablespace
  FROM dba_users)

  1 if you have Diagnostic Pack license that you can try to use DBA_HIST_TBSPC_SPACE_USAGE, but it has only a dozen days of history. See http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/statviews_3195.htm#I1023456.

  2. an Oracle user cannot use a specific UNDO tablespace: a user can only use a specific permanent tablespace or a specific temporary tablespace.

• Calculate the space used in the database!

  Hi all
  
  I can calculate the space used by using one of the following ways:
  
  1. determine the size allocated by issuing
  
  SELECT SUM(d.bytes/1024/1024/1024)
  FROM dba_data_files;
  
  2 calculate the free space by issuing
  
  SELECT SUM(bytes/1024/1024/1024)
  from dba_free_space;
  
  Space used will be the value of the first statement - value of the second statement. This is manually!
  
  Is it possible to combine these two queries?
  
  Thank you!
  
  Dan.

  You can certainly combine queries

  SELECT (allocated.bytes - free.bytes )/1024/1024/1024 used_gb
    FROM (select sum(bytes) bytes from dba_data_files) allocated,
        (select sum(bytes) bytes from dba_free_space) free
  

  Normally, you could group tablespace as well.

  But if you want just the amount of space used, it is probably easier to just

  SELECT sum(bytes)/1024/1024/1024 used_gb
    FROM dba_segments

• What is better to use the database or persistence.

  Hello friends,

  I have a doubt in relation to the use of the database and persistence.

  I'm working on an application based on OS_v5.0, I use a database to store my data or persistence.

  While it will be better to use as prospect of memory and speed.

  Thank you

  There is no right answer here.  Include critical factors

  (a) the data structure - is that he opposes or ranks

  (b) the size of the data,

  (c) how the data should be used

  (d) what coding effort, you are willing to put in.

  You must weigh all these factors before making a decision.

  Maybe you can give some pointers in each of these areas and we can suggest how we were?

• With regard to the size of the database

  Hi all
  
  Sorry for the interruption of you and your time for the clarification.
  
  The size of my database is:
  Select sum (bytes) / 1024/1024 of dba_data_files;
  
  SUM (BYTES) / 1024/1024
  --------------------
  19035.0938
  
  The size used is:
  Select sum (bytes) / 1024/1024 in dba_segments;
  
  SUM (BYTES) / 1024/1024
  --------------------
  5488.22656
  Free size is:
  Select sum (bytes) / 1024/1024 dba_free_space;
  SUM (BYTES) / 1024/1024
  --------------------
  13890.1016
  
  When I take plenty of RMAN backup I found the size almost 2304 MB (but in dba_segments his ~ 5488), my doubt is how to remove the higherwatermark (HWM) so that I can get exactly space used by database (excluding higher watermark).

• Convert the database to 10 v to v11

  Hello

  I'm unable to convert and merge a v10.1 v11 user database.  I made a backup of Usrcomp_S.usr to another folder in Windows then used the merger of Multisim and Ultiboard and conversion tools. Here are the steps I followed:

  1 tools > Database > convert database...

  2. Select Source in the dialog context database names.

  3. navigate to the database using the Windows dialog box. Select my copy of database using "All Files." Curiously he is not using the default filter. Select OK and then the following error:

  The path of the database: "database\UsrComp_S.usr" was not found or not set.
  You want to select the path where the database of component?

  4. Select Yes then select my now visible database of the dialog Windows.

  5. press start to convert my database to aid auto rename. Briefly, something happens that seems to be the conversion and the window convert watch Done

  6. close the convert and open tools > database > merge a database...

  7. Select a name of the component database

  8. Repeat step 3 above. The allegedly converted database is still not visible but this time there is no option to "All Files." In the file name drop-down box I choose the path previously used for the database copy. Select open and receive the following error message:

  The path of the database: "database\UsrComp_S.usr" was not found or not set.
  You want to select the path where the database of component?

  9. Select Yes then select my now visible database of the dialog Windows.

  10. press on open and receive the following error message:

  Error: Could not open the database [user data].
  The file format/version does not, and cannot be merged.
  If the database is from a previous version, use convert the database.

  Help, please. This should be a simple process of a button to import parts of the user of a previous version.

  Richard

  Hi Richard,

  I think you are trying to convert the incorrect database. From the name you specified (Usrcomp_S.usr), it's just a CDS model uses to create a user database, it is not your user database.

  On Windows XP, the user database is located in C:\Documents and Settings\\Application Data\National Instruments\Circuit Design Suite\11.0\database\

  On Windows Vista/7, the user database is located in C:\Users\\AppData\Roaming\National Instruments\11.0\database\

• Calculation of the size of the database.

  Salvation of DBA. Which is exactly the way to calculate the size of the database? Is it calculate the sum of the sizes of the segments or the calculation of the sum of the sizes of the redo logs, data files, control files?

  You please suggest the correct answer

  Thank you

  As usual: depends: do you need to calculate the size allocated on storage, you simply go to the current size of the file dba_data_files bytes column data. If you need the storage used the sum of dba_segments fits better. If you need the size of all files used for the database, you must add the controlfiles, newspapers and db_recovery_file_dest_size files.

• index created in the database

  Hello

  the FSCM 91, on Win 2008, 8.52 tools, Oracle 11g DB.

  If an index is created, not in the designer application (but in SQLPLUS for example) it would be PeopleSoft when navigation or execution of a batch by the process scheduler?

  In other words the PeoplSoft indices must absolutely be created in application designer?

  Thank you and best regards.

  AFAIK PeopleSoft not explicitly use optimizers in SQL as referring to specific indices.

  Indexes are used by the database (Oracle) when sql is running.

  All objects, you can create the application designer, should also be created in the application designer.

  That are part of the metadata PeopleTools and, therefore, you can add these items, also the indexes, projects and migrate into other environments using application designer.

• Cannot find the HDL Interface node

  I have MyRio and LabView 2014 with all modules installed and updated to date.

  Xilinx 2014 is also installed and I can compile for FPGA.

  However, in the block diagram I find interface HDL node for the import of VHDL code. As see you in the second screenshot.

  How can I solve this problem?

  

  

  There are no node integration IP in 2014 of LabView. Use instead the HDL Interface Node.

  Yes I used the HDL Interface Node and it has worked very well.
