• How to check what database is used by VMware Virtual Center?

  Hello

  I recently inherited a small environment and I was asked to upgrade ESX 3.5 to ESX 4.0. I'm not a person from the database, but how can I check what database is used by VMware Virtual Center? According to the guide to upgrade the MSDE database is not supported in ESX 4.0.

  I want to just make sure that we did not use this database. I looked in the ODBC Data Source Administrator. Thanks to the system DSN, I saw that the drivers for Vmware Update Manager and Vmware Virtual Center are "SQL Native Client". Also registry editor, I watched HKEY_LOCAL_MACHINE-> SOFTWARE-> VMWARE, INC.-> VMware Virtual Center-> DB. Data on 'Vmware VirtualCenter' next to '1' and '4' is set to "SQL Native Client".

  So, how can I determine if the database used is not MSDE?

  Sorry for the stupid question, but I'm not so much with the databases...

  Thank you.

  > So, how can I determine if the database used is not MSDE?

  MSDE does not remote databases.  ODBC Open, click System DSN, click Configure.  The listed database is that it uses, and if that is the name used for virtual center, this is the database in use.

• What databases are available on the BB? How can I access it desktop?

  Hi all

  Please can someone tell what databases are available or possible to maintain on the BlackBerry Curve 8300? Is it possible to have .csv files separated by commas.

  Secondly, how can I access these databases on a device that uses the resident program on the desktop?

  Thank you.

  We do similar things to what you seem to want, with data on a BlackBerry.  We have the client software on the BlackBerry that synchronize data with the server.  The server can push updates, but this only (currently at least) works in a BES environment.  Once the data are extensive, the application program that receives the data can do what he wants with it, including be persisted.

  If you don't want to write all of this, then I would look at Sybase offer.

  See the httppushdemo comes with the JDE for an example of PUSH to work.

• What ODI protocol uses to communicate over the network?

  We need to open ports in the firewall to allow the ODI to connect to another instance, but we want it open only for the protocol used by ODI. It would be something like SQLNet or HTTP.

  In general, communication purposes with an agent of the ODI for invocation (i.e. perform scenarios etc.) is performed via the HTTP protocol on port defined by the user, as far as I know - TCP port 20910 is often used. If the communication with the agent of ODI is protected with SSL / TLS, then the initial communication would take place over HTTP on port defined by the user in front of an encrypted tunnel is set up by using the SSL / TLS protocol.

  Database connectivity is also at the level of the network as you say properly and according to the particular database that you are using a different application level protocol will be used by the JDBC driver. For example, database connections Oracle would use the TNS (the TCP port default 1521) Protocol while MS SQL uses the Protocol (TCP port 1433 by default) TDS, but these ports can be customized. If you use tools such as SCP in ODI while you need to open ports between the agent and the target computers so that for example you can access SSH on the target (TCP 22 for SSH default port) machine and so on.

  What this really means to however, it is exactly that you need to open TCP ports would depend on what tools you use in ODI and what technologies are, you connect from / to. It depends also to some extent how smart is your firewall and if it can detect the level protocols such as HTTP application with inspection packages rather than having to allows you to configure ports specific TCP rather than application-level protocols, for example TCP 20910 port.

• APEX on a database by using a different database security

  I'm new to APEX so please forgive me if my question is elementary or if it crosses also ignoring.  My organization uses APEX for the first time and you are looking to fill a specific role.  I don't know if we want APEX can be done.

  Here's what we want to do:

  We want to create an app of the APEX on A database.

  My APEX application will be used to modify database tables b.

  Users have usernames, passwords and access set up on the basis of data B.

  When users access the application of APEX, we want the application to use the database security B.  In other words, it connects using the IDs and passwords for database B.

  So:

  I go to the application of the APEX

  He invites me to the user ID, I enter one I use when I log on database B.

  He asks me a password, I get the one I use with database ID B.

  I click OK.

  Forms are loaded with the data accessible by my ID on the B database.

  Changes on the forms and my user ID is marked as one making changes to database b lines.

  In other words, I just want to use the database A to build and enhance the application.  Anyone can run the application, but they must connect using their database B ID and password to make changes.

  (1) is it possible?

  (2) how to configure in the application of the APEX?

  Thanks for your help on this.

  APEX does not work like that.

  APEX is nothing more than a bunch of PL/SQL code that runs on the database, it is installed on and run the code as "pattern analysis".

  Comment on "works on the basis of data"

  If you want APEX to read data from a different database, you use a DATABASE LINK

  for example to SELECT a report

  Select * from scott.emp@db2

  I doubt that one of the assistants APEX you'll love.

  comment "works like «pattern analysis"»

  If your application has an analysis of 'BOB' scheme... all SQL and PL/SQL code will run as BOB.

  The "DB"account "security" is more a misnomer.  APEX only checks that the entered name and password match that of the database that it is installed on.

  Once verified, APEX performs a 'switch user' for the 'scheme of analysis. "  (Authentication of proxy in Oracle)

  That's how web applications work... they use a shared schema.

  WORK AROUND

  Connect to the APEX by ADR, no EPG.  Will prevent it people to access the database directly.

  The next thing that you need is a SCHEME of ANALYSIS dedicated to the execution of SQL and PL/SQL.

  As any other database USER, it shouldn't be the same schema as the schema that contains all of your data. (Analysis schema! = data schema)

  Personally, I like to my 'space work [schema]' separated also.

  You will most likely need to use a database of private virtual control data access.

  Required Code changes

  If none of your code using the username 'USER' column, you need to change to COALESCE (V ('APP_USER'), USER)

  (I prefer to COALESCE on NVL because I anticipate different infrastructure that works similar to APEX)

• Database ALTER DATABASE RECOVER using backup controlfile with AUTO option

  Hello. I was recovering a database today and had a little blip.

  I have published the following:

  Database ALTER DATABASE RECOVER using backup controlfile

  I then chose the AUTO option, allowing Oracle to select all available log files so that it would recover to the last log found in the destination of archive

  Hi Kumar,

  In 10g, you can query x$ ksxpia. If the cluster_interconnect is stored in the OCR (by default), you will get

  If you have specified the cluster_interconnects parameter in your init.ora:

• What is the use of the DUMP function

  Hi friends,
  
  What is the Dump function? What is the use of dump? where can I use dump?
  
  ex:
  
  Select (sysdate) dump of double;
  
  Please expline with good example,
  
  
  By,.
  Symph.

  Sometimes you can have data in your database that you expect to be returned or excluded by a query, but you do not know why it does not work as expected. With the help of DUMP, you can examine the contents of the byte-by-byte data to help identify issues...

  SQL> with t as (select '&data' as dta from dual)
    2  --
    3  -- end of test data
    4  --
    5  select dta, dump(dta), dump(dta,16) from t;
  Enter value for data: Fred Smith
  old   1: with t as (select '&data' as dta from dual)
  new   1: with t as (select 'Fred Smith' as dta from dual)
  
  DTA
  ----------
  DUMP(DTA)
  ---------------------------------------------------------
  DUMP(DTA,16)
  ---------------------------------------------------------
  Fred Smith
  Typ=96 Len=10: 70,114,101,100,255,83,109,105,116,104
  Typ=96 Len=10: 46,72,65,64,ff,53,6d,69,74,68
  

  So my entry of "Fred Smith" looks like it's just two names separated by a space, but in reality in this example, the 'space' is the character ascii 255 (FF hex). This can be seen in the DUMP information. If it's data to my database, I would now be able to determine why, for example, I wasn't getting it back in my query when you query for "Fred Smith" by using a space character.

  There are other options as well, for example, to examine the character set...

  SQL> select dump('Fred Smith',1017) from dual;
  
  DUMP('FREDSMITH',1017)
  ------------------------------------------------------------
  Typ=96 Len=10 CharacterSet=WE8MSWIN1252: F,r,e,d, ,S,m,i,t,h
  
  SQL> select dump('Fred Smith',1016) from dual;
  
  DUMP('FREDSMITH',1016)
  ----------------------------------------------------------------------
  Typ=96 Len=10 CharacterSet=WE8MSWIN1252: 46,72,65,64,20,53,6d,69,74,68
  

  Take the result of the DUMP function you can use for all sorts of things based on what your needs are... example...

  In binary or hex string conversion...
