  7. Hi Priyatosh Thanks for writing to us! PFB for the answer to your query. Upgrading JDK at source would be a better option as RHEL5 has some known issues with lower version of JDK. Oracle home can be upgraded later after Linux upgrade so out of option you can go to OPTION 1 Upgrade ORACLE_HOME and JDK on RHEL 5 and then migrate to RHEL7 Regards kirti

  15. During the private load balancer topic the ppt which has the diagram shows the loadbalance spans between 2 AD's, is that a mistake?
  16. Hi Arun, Oracle Cloud Infrastructure Compute consists of Virtual Machine & Bare Metal Machines which consist of Shapes, where shapes is a template that determines the number of CPUs, amount of memory, and other resources allocated to a newly created instance. In Oracle Cloud Infrastructure (Gen2 Cloud) as of Jan 2019, there are two types of Shapes available both for VM instances & Bare Metal Instances, which is Standard & Dense Shapes, the basic difference between Dense shapes & Standard shapes is the dense shapes comes with Local NVMe Storage which provides high IOPS & Standard shapes come with Block storage which provides low IOPS as compared to NVMe Storage. Earlier High shapes were also available, which comes with NVMe Storage but low with Storage capacity as compared to Dense shapes. To know more about Compute & various compute shapes in Oracle Cloud Infrastructure check here (https://k21academy.com/iaas18) To know more about Storage in Oracle Cloud Infrastructure check here (https://k21academy.com/iaas20) To know more various shapes available as of Jan 2019 in Oracle Cloud Infrastructure check here (https://docs.cloud.oracle.com/iaas/Content/Compute/References/computeshapes.htm#footnote_1_2) Thanks & Regards, Rohit (TeamK21)
  17. What is difference between Dense I/O and High I/O ?
  18. Hi Alekhya - Basically, connection Pool in Weblogic is used for DB connection and Connection Factory in Weblogic in used to make the connection with third party application/Service provider . Please correct me if I have understood it correctly. Thx
  19. Hi Priyatosh, Thanks for writing to us! PFB for the answer to your query. Connection Pool is some thing like a pool of database connection maintained at one place so that an application or client can use it whenever it requires. A client uses connection factory to create a connection with a service provider i.e generally JMS.Mainly this is used for Setting Up a JMS Application. Thanks and Regards, Alekhya
  20. What is the difference between connection pool and connection factory ? In which context they can be used ?
  21. [AK] Please find the steps for OHS Error customize page 1. First, you create customize page and developed it under <ORACLE_INSTANCE>/config/OHS/<component_name>/htdocs. Just make sure the size of the page should be more than 50 KB. 2. Now Open the OHS httpd.conf file located at <ORACLE_INSTANCE>/config/OHS/<component_name> 3. search in the editor like ‘ErrorDocument 403’ which can be seen as commented text and Next to the commented text line, add the below lines for configuring the Error Pages as error403Page.html are deployed in OHS htdocs. 3) Save the changes to the httpd.conf file. 4) Restart OHS server <ORACLE_INSTANCE>/bin/opmnctl restartproc ias-component=<component-type> 5) Also you check the error 403 or 404 for apache and add the page for that as well and trace the HTTP Headers as well to check the changes and where the error is coming
  22. [AK] seems like in your moveplan.xml file the instance home path is different, can you please check again the moveplan.xml file and see the instance path if you found the path is different then take the backup of moveplan.xml file and change in file and then run the copyconfig to reflect the changes please
  23. This question is from one of the trainees from our Oracle Fusion Middleware Training. Query - I am cloning obi, while running pasteconfig.sh, for instance, it is showing error SEVERE : The instance home path specifed in domain move plan should be used. Any change requires a rerun of domain config.
