2. 2 DBA Issues Connectivity Two Data Dictionaries Keys & Indexing Tablespaces (Oracle) Space Management (Oracle) SQL Optimisation Rollback Segments (Oracle) Backup Considerations Performance Metrics

3. 3 Connectivity What happens when you connect Usage of the word ‘database’ Security Tracing PS/Query, Crystal & ODBC

4. 4 What happens when you connect? 2-tier Connection

5. 5 What happens when you connect? Connect=H75D/PS/ EXECUTE :1 := SQLCQR_LOGINCHECK(:2) SELECT OWNERID FROM PS.PSDBOWNER WHERE DBNAME = ‘H75D’ SELECT OWNERID,TOOLSREL,TO_CHAR(LASTREFRESHDTTM,'YYYY-MM- DD HH24:MI:SS'), TO_CHAR(LASTCHANGEDTTM,'YYYY-MM-DD HH24:MI:SS'), SECURITY_OPTION FROM SYSADM.PSLOCK SELECT VERSION, OPRTYPE, OPERPSWD, ACCESSID, ACCESSPSWD FROM SYSADM.PSOPRDEFN WHERE OPRID = ‘PS’ Connect=H75D/SYSADM/ SELECT TO_CHAR(SYSDATE,'YYYY-MM-DD HH24.MI.SS."000000"') FROM PSCLOCK SELECT VERSION FROM PSLOCK

6. 6 What happens when you connect? 3-tier Connection

7. 7 What happens when you connect? Connect=H75D/PS/ COM Stmt=EXECUTE :1 := SQLCQR_LOGINCHECK(:2) Bind-1 type=18 length=2 value=0 Bind-2 type=2 length=254 value= Stmt=SELECT OWNERID FROM PS.PSDBOWNER WHERE DBNAME = :1 Bind-1 type=2 length=4 value=H75D Stmt=SELECT OWNERID,TOOLSREL,TO_CHAR(LASTREFRESHDTTM,'YYYY-MM- DD HH24:MI:SS'), TO_CHAR(LASTCHANGEDTTM,'YYYY-MM-DD HH24:MI:SS'), SECURITY_OPTION FROM SYSADM.PSLOCK Stmt=SELECT VERSION, OPRTYPE, OPERPSWD, ACCESSID, ACCESSPSWD FROM SYSADM.PSOPRDEFN WHERE OPRID = :1 Bind-1 type=2 length=2 value=PS Disconnect Connect=H75D/SYSADM/ Stmt=SELECT TO_CHAR(SYSDATE,'YYYY-MM-DD HH24.MI.SS."000000"') FROM PSCLOCK

8. 8 Usage of the word ‘database’ It is possible to have many ‘PeopleSoft’ databases in a single Oracle database Each PeopleSoft database resides in a single schema. Different PS databases have different schema. Not recommended for Oracle - Users in common between databases must have same passwords

9. 9 Usage of the word ‘database’ It is possible to have many ‘PeopleSoft’ databases in a single SQL Server Limited to one SQL Server per NT machine. Different databases can exist in different SQL Server databases within the same sever. Same problem with users in common, they must share the same password

10. 10 Security PS database usually owned ‘sysadm’ or ‘sa’ –= root, sys, system –The password to this account is the key to the kingdom.

11. 11 Tracing Tracing administered via configuration manager –i.e.. via registry

12. 12 PS/Query, Crystal & ODBC PS ODBC driver –Only defined PS/Queries can be seen

13. 13 Two Data Dictionaries Database Data Dictionary PeopleSoft Data Dictionary DDDAudit SYSAudit

14. 14 Tools Table -v- DB Catalogue

15. 15 Audit Reports DDDAUDIT –Compares data dictionaries (not columns) SYSAUDIT –Referential Integrity of Tools Tables Remedies in PeopleBooks

16. 16 Keys & Indexing Implied from Record Definition –Key –Duplicate –List (not Tools 8) –Alternate Search –Descending User Specified Constraints Suppressing Index build Sparse Indexing

17. 17 Implied from Record Definition Key –Duplicate List (not Tools 8) Alternate Search

18. 18 Field Attributes

19. 19 Key (Duplicate)

20. 20 Alternate Search

21. 21 List (not Tools 8)

22. 22 Descending Keys

23. 23 Search Dialogue SELECT DISTINCT DEPTID, DESCR, COMPANY, LOCATION FROM PS_DEPT_TBL WHERE DEPTID LIKE ‘10%’ ORDER BYCOMPANY, DEPTID

24. 24 Search Dialogue

25. 25 User Specified

26. 26 Constraints Unique –Implied by Unique Key Indexes Mandatory/Not Null Referential Integrity? –There aren’t any!

27. 27 Suppressing Index build

28. 28 Sparse Indexing (Oracle) Dates can be NULL

29. 29 Tablespaces (Oracle) Installation Scripts Temporary Tablespaces

30. 30 Temporary Tablespaces Create tablespace ‘ORATEMP’ Alter tablespace TEMPORARY –can only contain temporary segment –cannot contain any other object –no redo logging –alter temporary tablespace for all users Don’t do this to PSTEMP

31. 31 Space Management (Oracle/DB2) DDL models Default -v- Override parameters Feeding back reality

32. 32 DDL Models System-wide default storage options

33. 33 Parameters PeopleSoft Parameters –Square Brackets TBNAME, TBCOLLIST, IDXNAME, IDXCOLLIST, TBSPCNAME User Parameters –** delimited Delivered (Oracle) INIT, NEXT, MAXEXT, PCT, INDEXSPC

34. 34 Default -v- Override parameters Overrides in application designer

35. 35 How is the DDL/Overrides stored? Space Model Default Parameters Record & Index Parameter Overrides

36. 36 DDL Model PSDDLMODEL

37. 37 Default Parameters PSDDLDEFPARMS

38. 38 Record Parameter Overrides PSRECDDLPARM

39. 39 Index Parameter Overrides PSIDXDDLPARM

40. 40 Two Data Dictionaries Compare –Database Catalogue USER_TABLES, USER_INDEXES –PeopleTools PSDDLDEFPARMS, PSRECDDLPARM, PSIDXDDLPARM

41. 41 SQL Optimisation Tracing –Extract SQLcleanup.exe –replay Mass Change/AE/Cobol SQR

42. 42 Enabling Tracing

43. 43 Typical Trace Output 1-2285 0.861 Cur#1 RC=0 Dur=0.000 COM Stmt=SELECT VERSION, FIELDVALUE, TO_CHAR(EFFDT,'YYYY-MM-DD'), EFF_STATUS, XLATLONGNAME, XLATSHORTNAME, TO_CHAR(LASTUPDDTTM,'YYYY-MM-DD-HH24.MI.SS."000000"'), LASTUPDOPRID, FIELDNAME, LANGUAGE_CD, EFFDT FROM XLATTABLE WHERE FIELDNAME = :1 AND LANGUAGE_CD = :2 ORDER BY FIELDNAME, LANGUAGE_CD, FIELDVALUE, EFFDT 1-2286 0.000 Cur#1 RC=0 Dur=0.000 Bind-1 type=2 length=6 value=ACTION 1-2287 0.000 Cur#1 RC=0 Dur=0.000 Bind-2 type=2 length=3 value=ENG 1-2288 0.111 Cur#1 RC=0 Dur=0.000 COM Stmt=SELECT VERSION FROM PSLOCK

44. 44 SQLCLEANUP.EXE SELECT VERSION, FIELDVALUE, TO_CHAR( EFFDT, 'YYYY-MM-DD' ), EFF_STATUS, XLATLONGNAME, XLATSHORTNAME, TO_CHAR( LASTUPDDTTM, 'YYYY-MM-DD-HH24.MI.SS."000000"' ), LASTUPDOPRID, FIELDNAME, LANGUAGE_CD, EFFDT FROM XLATTABLE WHERE FIELDNAME = :1 AND LANGUAGE_CD = :2 ORDER BY FIELDNAME, LANGUAGE_CD, FIELDVALUE, EFFDT \ ACTION,ENG /

45. 45 Mass Change/AE/SQR What you see in the code is what you get –All PS programs can be traced

46. 46 SQL Optimisation (Oracle) SQL_TRACE = TRUE; Embed command Trigger on processes via process scheduler –PSPRCSRQST Set trace in session –2-tier client is multithreaded –Small Private Application server

47. 47 SQL_TRACE = TRUE; Initialisation Parameter TIMED_STATISTICS = TRUE In current session ALTER SESSION SET SQL_TRACE=TRUE; In another session EXECUTE sys.dbms_system.set_sql_trace_in_session (,,TRUE);

48. 48 Trigger for via process scheduler PSPRCSRQST create or replace trigger sysadm.set_trace before update of runstatus on sysadm.psprcsrqst for each row when (new.runstatus = 7 and old.runstatus != 7 and NOT new.prcstype IN(’Crystal’, ’PSJob’) ) begin sys.dbms_session.set_sql_trace(true); end; /

49. 49 Set trace in session 2-tier client is multithreaded Small Private Application server –EXECUTE sys.dbms_system.set_sql_trace_in_session (,,TRUE);

50. 50 Backup Consideration Connected Processes –Application Server –Process Scheduler –Batch Programs –2-tier users

51. 51 Performance Metrics Process Scheduler Table –PSPRCSRQST Trigger to capture history
