• Using VM Ware Server 2 for disaster recovery

  I tried VM Ware server and VM Ware converter quite earlier, and they have done wonders for purposes of recovery after a disaster.

  I just got a new server and I'm trying to do the same things. Then I noticed that VM Ware Server is upgraded to 2, and I can't find VM Ware converter. Can someone tell me what I can use to convert a server into a virtual image? I'm just very confused and do not have the time to read each documentation to find what I need. Thank you very much!

  Single use: it can convert a virtual machine at a time.  The paid for the product can be implemented to convert several machines and you can let it work.

• Flashback Database using Data Guard environment

  11.2.0.3/RHEL 5.8
  
  I came across several documents that speak of FLASHBACK DATABASE configuration in dataguard environments. We have several
  Physical DBs sleep (Single Instance & RAC) running in our shop. I would like to know two or three major (common) use of FLASHBACK DATABASE data child care settings.
  
  I understand one of the uses mentioned in the below URL ie. a logical error recovery
  
  http://uhesse.com/2010/08/06/using-flashback-in-a-Data-Guard-environment/
  
  I would like to know what are the other major/common use of Flashback Database River in environment DataGuard

  A few other uses:

  (1) flashback allows you to test your DR. So you can activate your watch. Test the connectivity of network/applications and features on your recovery site and when done return the database to a physical standby. It must however ensure that this is allowed in your environment. In some places, I worked, it would be a big no, no, because they have no needs of data loss. However some companies that will allow as long that the watch is delivered in place for some time.

  (2) in the case that you do a failover for a reason, but what has been the main site would then become available, you can flashback what has been your primary to make the eve rather than re-instatiating the database from scratch.
  For example. You have a power failure on your main site if perform you a failover and your watch becomes the principal. Once it's your main site is back online, you can convert your previous primary in a day before making a full return/restoration (or any method you choose) to recreate your standby again. However you also have the option to use flashback on this database and then convert it to a watch because it would be potentially faster than the re-instantiation of the day before.

• Data Guard Vs Golden Gate

  Hello
  
  I have custody-transfer data disaster and now my planning to do more to implement the Golden Gate. My question is when you can protect your data and active pressure on the primary database using the Data Guard why someone should go to golden gate?
  
  Please let us know of your experience of Golden Gate on Data guard!
  
  One more thing, what is meant when someone using eve of terms and dataguard, dataguard active? Are not all the same?

  I have data-guard for disaster recovery and now my management planning to do more like implement Golden gate. My question is when you can protect your data and offload pressure on primary database by maintaining active data-guard why someone need to go for golden gate??

  One more thing, what is meant when someone using eve of terms and dataguard, dataguard active? Are not all the same?

  Active Dataguard is a device in which the database pending would be placed in open read-only mode and recovery (MRP/application log) would be ongoing. This is called as active dataguard and the wait would be in sync with the primary. The standby database when kept in open read-only mode can be used for purposes execute select queries. So, you would be having a function of the use of the database as a database, and at the same time the day before would apply the primary newspapers. This feature is available only from 11 g.

  In 10g or earlier versions, we had no such device. The database of rescue, if necessary use for reporting purposes, then the backup database must be open in read-only mode, but the recovery (MRP/application log) cannot be done. So, if you want that database waiting to have the application of fact log, then he must place in EDITING mode. If it will be used for the purposes of tax, then it must be placed in open READ ONLY mode and stop the recovery. Guests receive only 1 device at a time here.

• Data Guard and EHCC on Exadata - does work?

  Exadata Hybrid columnar Compression (OHCC) works when a database is in mode "force logging?
  
  I fear that it may not work because OHCC works only for inserts in direct mode, which means me no logging.
  
  We are in the process of purchasing a vault Exadata, a second target Data Guard.
  
  V11.2 documentation Data Guard is specifically stated that Data Guard doesn't support hybrid columnar compression, but I don't know what are the implications of this.
  
  I expect to have to solve the primary database Machine for 'forcing logging' Data Guard will be used.

  DataGuard physical or logical?

  Oracle fully supports data Guard physical standby and hybrid columnar Compression on Exadata.

  Direct support issues that may exist with Data Guard logic and therefore, at least at the present time, logic is not supported.

  The above is to the best of my knowledge that I don't have access to the documentation of the Exadata. But was certainly true of my
  last experience of HCC. Your Oracle sales representative should be able to provide the definitive answer quickly and I would be grateful
  post you here.

• Repository with Data Guard

  Can I use a database with Data Guard for HA with 'failover FastConnect' for your repository EM database?

  Yes, this is the preferred method. Take advantage of the opportunity DG to perform a trigger when the digital switchover / failover to move the service used by the WHO from the primary to the wait.

• How to get the webservices project customer specific use Oracle.

  I have a Web services project I developed in VS2005 where I use the Oracle.DataAccess.dll provided by Oracle 10 g ODAC to connect to an Oracle 8.1.7.4 database. I add a reference to the dll in the folder c:\oracle\product\10.2.0\client_1\ODP.NET\bin\2.x. I create and publish Web services and checked that Web services are working correctly. I ran into problems when I installed the latest version of the ODAC for Oracle 11, where the webservice Gets the following error ORA-03134 - this version of the server connections are more supported. Based on what I read here and ther panels, it seems that when I installed the ODAC for Oracle 11 he installed a policy file that redirects all calls to use Oracle 11 components data access rather than that I've specified explicitly in my project.
  
  Is it possible for me to always have the components of Oracle 11 working side by side with Oracle 10 g and forced my project to always use the components of Oracle 10 g?

• OIM 11 g database using Active Data Guard recovery

  Hello
  
  Someone did he do IOM database failover configuration using the active data guard.
  
  Here are the details
  • Two application in primary servers and one in secondary sites
  • Two databases one in primary and the secondary sites.
  • Two application servers point to the primary database.
  • There is an Active Data Guard set up between primary and secondary data.
  • Secondary database is in stand-by mode.
  • Unique CNAME is configured and actively points to the primary database.
  • Failover of the database, the principal is down and the secondary database is marketed as primary and CNAME is changed to point to the secondary database.
  • All the data sources in Weblogic are configured to use CNAME.
  
  The problem here is the SID. In the primary, we have JSQOIM1P and in the secondary, the SID is JSQOIMDR.
  
  So when we switch the error we get is unknown TNS name like Weblogic data sources don't know the JSQOIMDR.
  
  How do configure us the failover in this scenario?
  
  Thank you

  Hello

  I was able to achieve this by setting up a unique service name pointing to the primary db SID and the same name of unique service on the secondary db pointing to the db secondary sid.

  For the benefit of the users of the forum.
  CNAME - usoimdb pointing to primaryDBHost and can be changed to secondaryDBHost in the case of DR
  Service name - usoimdbsvc pointing to primaryDBSID and usoimdbsvc to secondaryDBSID on secondary db use

• Request to license Oracle Data Guard

  Nice day! at all. I don't know if this is already asked before, but I would like to ask for your help regarding my inquiry.
  
  We have an Oracle 10 g Database EE here in our company which is established in a RAC (2 nodes and 1 SAN). Of course, that are already approved.
  
  We intend to implement the Oracle Data Guard.
  
  Of course the Oracle Data Guard will run voluntarily for a disaster recovery, in the case that our CARS (especially the SAN) will crash, we would like to have a stand physically separated by our primary database server (stand by server is completely separate to our existing main server) server.
  
  My questions are:
  
  1. don't we have to take advantage of a new license for custody of data?
  2. what other license should we acquire for the above settings?
  3. we would have a separate Installation of Oracle database on the standby server?
  4. If we have a named user license 150 on the primary database should purchase us a new license user named 150 for the confirmation Server?
  5. are there other things I have to consider in what concerns the granting of licenses for our project?

  OK, here's how my speailist license put, Data Guard as a product is free, but is not the database instance. A physical standby is a database, it must be so licensed, however the expert of the license indicates that licenses you buy for the execution of the physical standby can be ubtained at a substantially reduced rate as they would be called limited licenses. It's not data hold is the cost, it is the cost of an another database on another machine. According to you, current license, you can be covered however, you may not. Everything I say is call a specialist to license Oracle Metalink support, call the guy or gal who has sold you Oracle licenses or appeal and certified Oracle partner/reseller can help you with a specialist of the license and have a licensing discussion/examination before implementation. Oracle support is not those who understand the licenses and how this all works, he did this and like them, always thought that data guard and physical databases Eve were free and included and recently corrected, hard enough I might add.

  Hello;

  I can perform a failover or a failover with Data Guard Broker in about 20 seconds. If I don't use a broker, it takes about 3 minutes.

  Quick start failover takes less time. Time will depend on the material, etc. of configuration options.

• 100% ram used on Data-Guard

  Hello
  
  We test our application with Oracle data guard.
  Is version of Oracle 11 g R2 (11.2.0.2)
  The configuration of data-guard is a primary and a physical standby server.
  Both servers have 16 GB of RAM. It is set on an ESX Server as two virtual machines.
  Each vm has two processors with a speed 2127,902 MHz
  OS is Red Hat Enterprise Linux Server version 5.5 (Tikanga)
  It's an arch bit x86_64 machine.
  
  The problem we see is that the consumption of RAM is almost 100%. (97%)
  Earlier, the RAM has 4 GB, believed is not enough and went to 16 GB after we found that same 8 GB is not enough.
  Even after setting the RAM 16 GB, entire memory was used.
  The demand for good results, the answers are quick enough.
  On average, there are 12000 inserts per minute in the database.
  
  The CPU usage is about 25%.
  
  
  We are looking to reduce the consumption of memory less than 80% so that if other applications must be run on the Data-Guard allows him to run or use nearly 100% of memory during the peak or abnormal conditions.
  
  It is a facility dedicated with instance what a single database that is running on the firewall data.

  Hello

  on Linux, high mem use is normal. Linux uses all the memory cache of the drive. You can compile this program to prove.

  #include 
  #include 
  #include 
  #include 
  
  int main(int ac, char **av)
  {
          long int n,m,i;
          long delay;
          char *buf;
  
          if(ac < 3) {
                  printf("Usage: %s  \n",av[0]);
                  exit(1);
          }
          sscanf(av[1],"%d",&n);
          sscanf(av[2],"%d",&delay);
          m=n*1024*1024;
          buf=malloc(n*1024*1024);
          // for(i=0;i
  

  and run it as follows:
  . 4000 10 a.out

  It will affect 4000 MB of ram 10 seconds. You'll see that once it's over, you have 4 000 MB of free ram. After awhile, this amount will be lower that linux will do IO operations.
