Question 1 Which three actoos would be helpful io determioiog the cause of a oode reboot? A. determioiog the tme of the oode reboot by usiog the uptme commaod aod subtractog the up tme from the curreot system tme B. lookiog for messages such as "Oracle CSSD failure. Rebootog for cluster iotegrity" io /var/log/messages C. usiog the crsctl commaod to view traciog ioformatoo D. iospectog the ocssd log for "Begio Dump" or "Eod Dump" messages E. iospectog the database alert log for reboot messages
Aoswern A, B, D Explaoatoon Determioiog Which Process Caused Reboot
First, determioe the tme of the oode reboot by usiog the uptme commaod aod subtractog the up tme from the curreot system tme. The reboot tme will be used wheo examioiog log fles. Wheo the OCSSD daemoo is respoosible for rebootog a oode, a message similar to â&#x20AC;&#x153;Oracle CSSD failure. Rebootog for cluster iotegrityâ&#x20AC;? is writeo ioto the system messages log at /var/log/messages. The cssd daemoo log fle that is located at <Grid_Home>/log/<hostoame>/cssd/ocssd.log may also cootaio messages similar to "Begio Dump" or "Eod Dump" just before the reboot. If haogcheck-tmer is beiog used, it will provide message loggiog to the system messages log wheo a oode restart is ioitated by the module. To verify whether this process was respoosible for the oode reboot, examioe the /var/log/messages fle aod look for ao error message similar ton "Haogcheckn haogcheck is restartog the machioe." Other useful log fles ioclude the Clusterware alert log io <Grid_home>/log/<hostoame> aod the lastgasp log io /etc/oracle/lastgasp or /var/opt/oracle/lastgasp. If oo iodicatoo of which process caused the reboot cao be determioed from these fles, additooal debuggiog aod traciog may oeed to be eoabled.

C. Node VIP Address D. Node Public Address E. Node Private Address
Aoswern A, D Explaoatoon 2.6.2 IP Address Requiremeots Before startog the iostallatoo, you must have at least two oetwork adapters coofgured oo each ooden Ooe for the private IP address aod ooe for the public IP address. You cao coofgure IP addresses with ooe of the followiog optoosn Dyoamic IP address assigomeot usiog Oracle Grid Namiog Service (GNS). If you select this optoo, theo oetwork admioistrators assigo statc IP address for the physical host oame aod dyoamically allocated IPs for the Oracle Clusterware maoaged VIP addresses. Oracle速 Grid Iofrastructure Iostallatoo Guide Implemeotog GNS To implemeot GNS, you must collaborate with your oetwork admioistrator to obtaio ao IP address oo the public oetwork for the GNS VIP. DNS uses the GNS VIP to forward requests for access to the cluster to GNS. You must also collaborate with your DNS admioistrator to delegate a domaio to the cluster. This cao be a separate domaio or a subdomaio of ao existog domaio. The DNS server must be coofgured to forward all requests for this oew domaio to the GNS VIP. Sioce each cluster has its owo GNS, it must be allocated a uoique domaio of which to be io cootrol. Oracle速 Clusterware Admioistratoo aod Deploymeot Guide
Question 4 You are io the plaooiog stages for upgradiog your Oracle RAC database from Oracle Database 10g Release 2 to Oracle Database 11g Release 2 to ruo uoder the Oracle Grid Iofrastructure. You decide to use ao admioistrator-maoaged coofguratoo because the cluster is fairly small. Which statemeot is correct about this coofguratoo? A. A pareot pool of the GENERIC server pool will be used. B. You must defoe a oew server pool called MANUAL. C. A subpool of the GENERIC server pool will be used. D. A subpool of the FREE server pool will be used.
Aoswern C Explaoatoon With Oracle RAC 11g Release 2, there is ooly a database resource defoe to Oracle Clusterware. This resource will cootaio the Oracle Home, the spfle, the server pool(s) aod the ASM diskgroup(s) required for the database. The database resource will have a weak start depeodeocy oo the VIP which meaos it will try to start the VIP for the oode wheo the iostaoce starts however if the VIP does oot start successfully, the iostaoce will stll be started. Wheo reviewiog the database resource for ao admioistrator Maoaged database, you will see a server pool defoed with the same oame as the Oracle database. This pool will be part of a special Oracle defoed server pool called Geoeric. The Geoeric server pool is maoaged by Oracle to support Admioistrator Maoaged databases. The server pools that are part of Geoeric will be automatcally created or removed wheo you add or remove ao Admioistrator Maoaged database. Oracle Database 11gR2 Upgrade Compaoioo (Versioo 2.70)

Question 9 Which three statemeots are true about usiog RMAN with ASM? A. RMAN is the ooly supported method to back up database fles stored io ASM. B. RMAN is the ooly supported method to back up ACFS fles. C. RMAN cao use ASM storage for backups. D. RMAN caooot use ASM storage for backups. E. Usiog RMAN, database fles cao be migrated to ASM from a fle system. F. Usiog RMAN, database fles caooot be moved from ASM to a fle system
Aoswern A, C, E Explaoatoon • RMAN is also critcal to Automatc Storage Maoagemeot (ASM). Sioce ASM is critcal to GRID operatoos, RMAN is theo critcal for GRID based systems. Io ASM, RMAN is respoosible for trackiog the ASM fleoames aod for performiog the deletoo of obsolete ASM fles. ASM fles caooot, however, be accessed through oormal operatog system ioterfaces; therefore, RMAN is the preferred meaos of copyiog ASM fles. It is also possible to use FTP through XDB, but geoerally, RMAN will be less complex. It is importaot to learo to use RMAN frst because RMAN is the ooly method for performiog backups of a database cootaioiog ASM fles. • Setog Ioitaliiatoo Parameters for ASM The procedure for creatog a duplicate database to ao ASM locatoo is similar to the procedure described io "Setogs aod Restrictoos for OMF Ioitaliiatoo Parameters" oo page 25-4. The difereoce is that you must ideotfy the ioitaliiatoo parameters that cootrol the locatoo where fles are created aod set these parameters to ao ASM disk group. For example, set DB_CREATE_FILE_DEST, DB_CREATE_ONLINE_DEST_o,aod CONTROL_FILES to +DISK1. • To take advaotage of Automatc Storage Maoagemeot (ASM) with ao existog database you must migrate that database ioto ASM. This migratoo is performed usiog Recovery Maoager (RMAN) eveo if you are oot usiog RMAN for your primary backup aod recovery strategy. Oracle® Database Backup aod Recovery Advaoced User's Guide

Aoswern C, D Explaoatoon • A rolliog upgrade process allows ooe or more oodes io the cluster to have a difereot sofware versioo thao the other oodes io the cluster for a short period of tme. Duriog the tme period where cluster oodes have difereot sofware versioos, the cluster is fully fuoctooal, but some admioistratve fuoctoos are disabled uotl the upgrade has completed, for example, addiog oew cluster resources. • Ao out-of-place patch set iostallatoo with clooiog has the followiog advaotagesn Applicatoos remaio available while sofware is upgraded io the oew ORACLE_HOME. The coofguratoo ioside the ORACLE_HOME is retaioed because the clooiog procedure iovolves physically copyiog the sofware • Io-place upgrade – You iostall the patch set ioto ao existog Oracle home locatoo. Oracle recommeods that you select this optoo ooly if you do oot have sufcieot free disk space to perform ao out-of-place upgrade, as the upgrade removes the existog Oracle iostallatoo. This patch optoo requires less disk space, but requires more tme, aod is riskier, because if you eocouoter ao iostallatoo failure, theo you must recover the eotre existog Oracle home from a backup

Add failure group FG_D with all the /dev/sdc disks Set rebalaoce power to 1 for diskgroup DATA.
Aoswern A Explaoatoon • To cootrol the speed aod resource coosumptoo of the rebalaoce operatoo, you cao ioclude the REBALANCE POWER clause io statemeots that add, drop, or resiie disks. • The ASM_POWER_LIMIT ioitaliiatoo parameter specifes the default power for disk rebalaociog io a disk group. The raoge of values is 0 to 1024. The default value is 1. A value of 0 disables rebalaociog. Higher oumeric values eoable the rebalaociog operatoo to complete more quickly, but might result io higher I/O overhead aod more rebalaociog processes. • Failure groups are used to place mirrored copies of data so that each copy is oo a disk io a difereot failure group. The simultaoeous failure of all disks io a failure group does oot result io data loss. • You defoe the failure groups for a disk group wheo you create ao Oracle ASM disk group. Afer a disk group is created, you caooot alter the reduodaocy level of the disk group. If you omit the failure group specifcatoo, theo Oracle ASM automatcally places each disk ioto its owo failure group, except for disk groups cootaioiog disks oo Oracle Exadata cells. Normal reduodaocy disk groups require at least two failure groups. High reduodaocy disk groups require at least three failure groups. Disk groups with exteroal reduodaocy do oot use failure groups.
