1 DB2 10 fr z/os System Administratin Day(s): 5 Curse Cde: CV851G Overview The curse is updated fr DB2 10 fr z/os. This is the Classrm versin f Instructr-led Online Curse (3V851GB). Administratrs f DB2 10 fr z/os can acquire a view f the architecture and fundamental prcesses required t manage a DB2 10 fr z/os subsystem. Engage in lectures and hands-n labs t gain experience t: Relate the z/os IPL prcess t a DB2 subsystem Explain effects f stpping and starting DB2 Explain hw DB2 sets and use Integrated Catalg Facility (ICF) catalg names The use f DSN cmmand prcessr running in batch and fregrund Use views t minimize users' ability t see int the DB2 catalg See hw the catalg (thrugh grant activity) cntrls access t data Search the catalg fr prblem situatins Use the catalg and DB2 utilities t determine data recvery requirements Describe Internal Resurce Lck Manager (IRLM) in a DB2 envirnment Implement DB2 and Resurce Access Cntrl Facility (RACF) security Describe DB2 prgram flw fr all envirnments Display nrmal and prblem threads and database status See hw the SQL Prcessr Using File Input (SPUFI) AUTOCOMMIT ptin defers the COMMIT/ROLLBACK decisin Interpret lck displays Identify and cancel particular threads Describe available DB2 utilities t manage system and user page sets Pre-Requisites Yu shuld have: an understanding f the bjects (tables, indexes, databases, and s frth) used in DB2 systems, and f hw thse bjects are created, managed, and recvered. These skills can be develped by taking: DB2 Database Administratin Wrkshp (CF83GB)/(CV830GB) r thrugh equivalent experience. Yu shuld als have a wrking knwledge f SQL that can be prvided by taking: DB2 SQL Wrkshp (CF12GB)/(3E12GB)

2 In additin, yu shuld have: At least ne year as a z/os systems prgrammer r equivalent experience Or, ne year wrking with DB2 n the mainframe as a DBA n the mainframe r equivalent experience Cntent Basic architecture and fundamental mechanisms Explain the principles f: IPLing z/os TSO/E LOGON Allcatin CLIST Cntrl f DB2 START DB2 prcess DSNZPARM member DB2 address space structure DB2 lg Catalg and directry Data sharing feature Cnnectin prcess Cmmand ruting prcess Prgram preparatin and executin prcesses Transactin and pints f cnsistency Set up and tune the IRLM Recgnize the imprtant IRLM parameters System security Prtect DB2 data sets when DB2 is up r dwn Prtect cnnectins t DB2 Describe the high-level peratin f DB2 security exits DB2 prgram flw fr all envirnments Describe DB2 prgram executin Explain what a DB2 thread is Explain cmmit prcessing Describe cnnectin types DSN CAF IMS CICS RRSAF

3 TSO and batch envirnments Describe TSO facilities Describe the facilities f DB2I Invke the DSN cmmand prcessr in varius ways Invke DB2 utilities Describe the QMF envirnment DB2 authrizatin Prvide apprpriate authrizatin fr yur user cmmunity Mnitr authrizatin in the DB2 catalg Effectively assign administrative authrities like SYSADM, DBADM, and BINDAGENT Create bjects fr thers Lgging Explain the basic algrithms f the DB2 lgging facility Set up and perate yur lg efficiently Recver frm BSDS failures Recver frm certain lst lg data set situatins Explain the use f the lg maintenance tls DB2 9 fr z/os utilities Categrize and discuss DB2 utilities Explain hw t back up and recver DB2 bjects using BACKUP SYSTEM and RESTORE SYSTEM utilities Define high-level qualifier fr catalg and directry Rename DB2 data sets Print lg map f BSDS Object recvery Describe the different types f applicatin recvery Perfrm varius health checks t detect damaged data Read the lg using DSN1LOGP Avid certain lst lg scenaris Transactin flw in IMS and CICS Describe the tw-phase cmmit prcess Explain thread recycling and the cmplete cnnectin prcess fr a DB2 thread Describe the input t and utput frm a SIGNON exit CICS - DB2 envirnment Outline a CICS cnnectin t DB2

4 Use the DSNC transactin Encurage CICS thread recycling Operatins (mnitring and cntrlling DB2) Mnitr and cntrl DB2 Train peratrs at yur lcal site Discuss the functins f ATS (Administrative Task Scheduler) System recvery/restart Describe the DB2 restart prcess fllwing bth nrmal and abnrmal terminatins Prevent restart failures Recver frm restart failures Begin planning fr ffsite recvery IMS - DB2 envirnment Integrate IMS transactins int the DB2 envirnment Integrate IMS BATCH jbs int the DB2 envirnment Cntrl which plans, subsystems, and cnnectin IDs transactins and batch jbs use Distributed - DB2 envirnment Describe the use f DB2 fr z/os enterprise servers in a multitier envirnment Explain the difference between JDBC and SQLJ Describe the Java database cnnectivity capabilities: use SQLJ and/r JDBC Dcument the requirements t set up the DB2 and Java envirnment in a z/os envirnment Objectives Start and stp the DB2 subsystem Explain the allcatin CLIST used at lgn fr DB2 data sets Use Set SYSPARM cmmand Lcate the Cmmand recgnitin character fr the DB2 subsystem Query the system lg t gain knwledge abut the IPL prcess and infrmatin in the system lg when DB2 is initialized r stpped Explre DB2 Address Spaces infrmatin Select the DB2 functins that best satisfy yur site requirements Explain the use f RACF fr DB2 cnnectin security Explain the use f Rles and Trusted Cntext Implement security prcedures fr a DB2 envirnment Describe the cmpnents and address space structure f a DB2 subsystem Explain DB2 Prgram Flw fr all envirnments Explain parameter settings fr the IRLM Display strage values fr the IRLMPROC

5 Dynamically change IRLM strage Estimate lck strage required fr the IRLM Invke and use DB2 TSO Facilities Use the DB2 Catalg t mnitr authrizatins Increase the size f the Active Lg data sets Explain DB2 Lgging Use SET LOG SUSPEND and SET LOG RESUME Use DSNJU004 t Print Lg Map Interpret the utput f Print Lg Map Use DSNJU003 t rename DB2 data sets Plan fr recvery f a BSDS failure Mnitr and cntrl DB2 Explain transactin flw in IMS and CICS Describe the CICS and DB2 envirnment Explain the difference between JDBC and SQLJ Target Audience This is an intermediate curse fr system administratrs, database administratrs, and ther technical individuals, wh manage and implement DB2 9 fr z/os.
