  2. Root causeis blocked LGWR due to LGWR waits LGWR waits ENQUEUE:CF contentionisasymptom of the db file scattered reads and excessive ITL waits

  3. Root causeis a blocked LGWR due to LGWR waits for enqueue:CF – contention, which may be held by another background process.Background process may hold a CF enqueue whileupdating the control file

  4. Root cause is blocked LGWR due to SCAN_LISTENERS(s) droppingclient connections during DoS event

You are upgrading from an earlier version of Oracle Clusterware to Oracle Clusterware12cR1 and want to store the OCR in an Oracle ASM disk group.What are the correct steps required to accomplish this task?

  1. Set the ASM Compatibility attribute to 10.2.0.1 or later.

    Verify you are running the correct version of Oracle Clusterware 12cR1 by issuing $crsctl query crsactiveversion

    Using srvctl create a disk group appropriately sized for the OCR you are migrating to ASM. As root, issue #ocrcheck -add DG_OCR

    As root, issue # ocrcheck -delete old_ocr_location

  2. Set the ASMCompatibility attribute to 10.2.0.2 or later.

    Verify you are running the correct version of Oracle Clusterware 12cR1 by issuing $crsctl query crsactiveversion

    Using acmca configure and start Oracle ASM onallcluster nodes.

    Using asmca create a disk group appropriately sized for the OCR you are migrating to ASM.

    As root, issue #ocrcheck -add DG_OCR

    As root, issue # ocrcheck-delete old_ocr_location

  3. Set the ASMCompatibilityattribute to 10.2.0.2 or later.

    Verify you are running the correct version of Oracle Clusterware 12cR1 by issuing $crsctl querycrsactiveversion

    Using crsctl, configure and start Oracle ASM on all cluster nodes.

    Using crsctl create a disk group appropriately sized for the OCR you are migrating to ASM. As grid infrastructure owner, issue # ocrconfig -add DG_OCR

    As grid infrastructure owner, issue # ocrconfig-delete old ocr location

  4. Set the ASM Compatibility attribute to 10.2.0.2 or later.

Verify you are running the correct version of Oracle Clusterware 12cR1 by issuing $crsctl query crsactiveversion

Using acmca configure and start Oracle ASM on all cluster nodes.

Using asmca create a disk group appropriately sized for the OCR you are migrating to ASM.

As root, issue #ocrdump -add DG_OCR

As root, issue # ocrdump -delete old_ocr_location

During theinstallation of OracleGrid Infrastructure 12cR1, you decide to configure the Grid Infrastructure Management Repository.Where will the repository be stored?

  1. In its own single instance Oracle Database 12cR1database and managed as a failover database

  2. Inthe first RAC database created on the cluster

  3. In its own RAC12cR1database with load balancing enabled

  4. On a nodeoutside thecluster to guard againstcluster failure

  5. Within the Grid Infrastructure home as a file-based repository

A customeris using thepolicy-managed database by name RACDB on a 4-node cluster. The server namesinthe Clusterare:dasher, vixen, comet, and dancer

There are two server pools defined, frontoffice and backoffice The attributes are as followsServerpoolmportance MinMax

Frontoffice1022 Backoffice512

There are two uniform services being created, crmsrv and hrsrv.

crmsrv is being assigned toserverpoolfrontoffice and hrsrv is assigned to backoffice.

Currently, allfour nodes are up and running. The database and its services are running as follows:

The serverpoolfrontoffice , which is running thecrmsrv service is being run on the dasher and vixen hosts

Theserverpoolbackoffice, whichis runninghrsvc service is being run on comet and dancer hosts.

What happens when the dasher node fails?

  1. Nothing happens because any service relocation is a major interruption to the clients who are connecting to the services.

  2. One of the nodes is moved from the backofficeserverpool to the fronofficeserverpool . This is moved with the consideration or importance and minimum attributes configured. Effectively, the crmsrv service wil run intwo nodes andhrsvc will run in one node.

  3. Rebootlescrs cluster stack willbe tried inallthe duster nodes to resolve the issue.If this is notresolved, allnodes in thecluster get bounced to resolve the issues

  4. Because the crmsrv serviceis defined asuniform servicethe cluster ensures at least one node is up and running, which is the current case. So, there will be no service relocation thatwillhappen.
