• How to connect two databases to a single listener

  Hello
  
  How to connect two databases to a listener.is it is possible or not

  Hello

  Yes, you can record a single listener to respond to several databases. There are several ways to do it and the best way that I would suggest for you is the use of "Network Setup Wizard" or "netca", which is a graphical interface that allows you to meet your requirement. Otherwise, you can hardcode in your listener.ora file located in the 'ORACLE_HOME/network/admin/listener.ora '.

  Example is as follows

  Listener.ora

  SCREW =
  (DESCRIPTION_LIST =
  (DESCRIPTION =
  (ADDRESS = (PROTOCOL = TCP)(HOST = lab01) (PORT = 1521))
  )
  )

  SID_LIST_VIS =
  (SID_LIST =
  -1 database configuration
  *(SID_DESC =*)
  * (ORACLE_HOME = /u01/app/oracle/product/11.1.0/db_1)*
  * (SID_NAME = DB1) *.
  *)*
  -Database Setup 2
  *(SID_DESC =*)
  * (ORACLE_HOME = /u01/app/oracle/product/11.1.0/db_1)*
  * (SID_NAME = DB2). *
  *)*
  )

  Then restart your listener.

• How to connect sql database to esxi to save all data from the virtual machine

  How to connect sql database to esxi to save all data from the virtual machine

  Please provide steps

  In simple terms, you cannot connect ESXi to SQL. Connect a vCenter SQL (Windows only).

  If you want to save all the data that is contained in your virtual machines, I suggest a backup solution.

• How to create a database using Labview7.1, as library management system?

  I want to use labview7.1 to create a database as the system.but management library I don't know how to do it.could you show me how to make it happen?

  To run database queries, OR sell the database connectivity Kit. However, given that your version of LabVIEW is no longer supported, I don't know if you could buy it. Your other option is to use LabSQL. Two of them are based on ADO. The Toolbox mask some SQL commands low level but you can find plenty of tutorials SQL and should be able to get updated quickly enough. LabSQL is what I use in my LabVIEW applications.

  The effective creation of a database is usually done in the database environment itself (for example, you use Access to create a Jet database). It is not really related to LabVIEW at all and appropriate database design is a long topic. If you know the system database that you want to use, someone might be able to point to specific aid.

• How to import xsd and use it in the transformation for mapping

  I built a xsd and you want to use the xsd to the development in BPEL Process.I imported. But I can't figure out how to proceed further. Anyone can suggest me how to import xsd and use it as it must be defined in wsdl using the law. Is it possible, we can use xsd?

  in the left lower structure window, the tree you can import patterns.
  When completed the scheme will get an element import in your wsdl file, so no manual work not needed for that.

  After that you can simply use it to create variables based on it

• Problems with cloning a database using copies of the image

  I use Oracle 10.2.0.4 on a 64-bit RHEL 4 Linux configuration.
  
  The problem that I am trying to solve is to copy the database to production on a local machine for development and quality assurance. I tried to include as much detail as possible.
  
  The environment:
  
  I have a production system that replicates physical expectations.
  We take incremental backups on the database of relief, which are applied to copies of the image, every night. We use a recovery catalog.
  Archive logs and a backup control files are stored in the same directory as the copies of the image.
  
  The process:
  
  We copied all files in this directory of backup on the local computer.
  At this point, I tried several methods to recover the database:
  
  1 clone:
  -J' copied the initialization file of the main machine to the local computer. I modified the creation of paths and memory settings.
  -J' did a trace of the control file and copied to the local computer.
  -After making the necessary adjustments to creative writing, I created the new control file
  -J' I then issued:

  recover database using backup controlfile until cancel;

  -After receiving the following:

  ORA-00279: change 313748229 generated at 09/14/2008 00:30:55 needed for thread 1
  ORA-00289: suggestion :

  ORA-00280: change 313748229 for thread 1 is in sequence #22304
  Specify log: {=suggested | filename | AUTO | CANCEL} 

  -I then entered CANCEL
  -A my next message: {codeORA-01547: WARNING: RECOVER succeeded but OPEN RESETLOGS would get below error}
  ORA-01194: file 4 recovery needs more match
  ORA-01110: data file 4:
  ' / u02/app/oracle/oradata/datatrak/ora_df664390338_s1145_s1.
  ORA-01112: media recovery not started {code}
  -Out of pure hope and prayer, I have published:

  alter database open resetlogs;

  -Made me the following error:

  ERROR at line 1:
  ORA-01194: file 4 needs more recovery to be consistent
  ORA-01110: data file 4:
  '/u02/app/oracle/oradata/datatrak/ora_df664390338_s1145_s1'

  Then, I moved to the possibility 2: RMAN
  
  2 RMAN restore:
  -J' first tried

  run { allocate channel ch1 device type disk; restore database; }

  -He gave me the following:

  allocated channel: ch1
  channel ch1: sid=1643 devtype=DISK
  Starting restore at 18-SEP-08
  released channel: ch1
  RMAN-00571: ===========================================================

  RMAN-06023: no backup or copy of datafile 2 found to restore
  RMAN-06023: no backup or copy of datafile 1 found to restore

  - Then I started cross-checking files:
  -datafile 1:

  allocated channel: ORA_DISK_1
  channel ORA_DISK_1: sid=1643 devtype=DISK

  -datafile 2 on:

  using channel ORA_DISK_1

  -J' I then issued:

  list incarnation of database;

  -Which gave me:

  List of Database Incarnations
  DB Key  Inc Key DB Name  DB ID            STATUS  Reset SCN  Reset Time
  ------- ------- -------- ---------------- --- ---------- ----------
  1       1       DATATRAK 3742967129       CURRENT 18136361   26-NOV-07

  -J' tried these two

  restore datafile 1;

  restore datafile '/u02/app/oracle/oradata/datatrak/ora_df664390339_s1151_s 1'

  which gave me the same results:

  Starting restore at 18-SEP-08
  allocated channel: ORA_DISK_1
  channel ORA_DISK_1: sid=1643 devtype=DISK
  RMAN-00571: ===========================================================

  RMAN-06026: some targets not found - aborting restore
  RMAN-06023: no backup or copy of datafile 1 found to restore

  -J' then went back at the beginning and tried to restore the controlfile instead of using the newly created controlfile
  -J' wrote:

  restore controlfile from '/u02/app/oracle/oradata/datatrak/cf_D-DATATRAK_i d-3742967129_i6jqcmaq';

  -Which gave me:

  Starting restore at 18-SEP-08

  RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

  RMAN-03002: failure of restore command at 09/18/2008 14:02:26
  RMAN-06172: no autobackup found or specified handle is not a valid copy or piece

  -After learning that we use autobackup to save our controlfile, now, I am faced with the proverbial wall.
  
  Excerpt from data pump and duplicate RMAN are possibilities, but we really want to do those.
  
  Any help on this issue would be greatly appreciated.

  Hello

  Now try:

  recover database using backup controlfile until cancel and when the message asking an archive appears, enter the good patch and name and press on enter, repeat it until the last archive you have, then enter Cancel.
