DBA Issues

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

3

Connectivity

• What happens when you connect

• Usage of the word ‘database’

• Security

• Tracing

• PS/Query, Crystal & ODBC

4

What happens when you connect?

• 2-tier Connection

5

What happens when you connect?

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

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

Security

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

the kingdom.

11

Tracing

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

12

PS/Query, Crystal & ODBC

• PS ODBC driver– Only defined

PS/Queries can be seen

13

Two Data Dictionaries

• Database Data Dictionary

• PeopleSoft Data Dictionary

• DDDAudit

• SYSAudit

14

Tools Table -v- DB Catalogue

15

Audit Reports

• DDDAUDIT– Compares data dictionaries (not columns)

• SYSAUDIT– Referential Integrity of Tools Tables

• Remedies in PeopleBooks

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

Implied from Record Definition

• Key– Duplicate

• List (not Tools 8)• Alternate Search

23

Search Dialogue

SELECT DISTINCT DEPTID, DESCR, COMPANY, LOCATION

FROM PS_DEPT_TBL

WHERE DEPTID LIKE ‘10%’

ORDER BY COMPANY, DEPTID

24

Search Dialogue

25

User Specified

26

Constraints

• Unique– Implied by Unique Key Indexes

• Mandatory/Not Null• Referential Integrity?

– There aren’t any!

27

Suppressing Index build

28

Sparse Indexing (Oracle)

Not Required Data Required

PS SQL Type PS SQL

Blank Not Null CHAR No Blanks Not Null

(Initialises DB with Space)

Zero Not Null NUMERIC No Zero Not Null

(Initialises DB with Zero)

No Date Null DATE Valid Date Not Null

Blank Null LONG VAR No Blanks Not Null

• Dates can be NULL

29

Tablespaces (Oracle)

• Installation Scripts• Temporary Tablespaces

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

Space Management (Oracle/DB2)

• DDL models• Default -v- Override parameters• Feeding back reality

32

DDL Models

• System-wide default storage options

33

Parameters

• PeopleSoft Parameters– Square Brackets

• TBNAME, TBCOLLIST, IDXNAME, IDXCOLLIST, TBSPCNAME

• User Parameters– ** delimited

• Delivered (Oracle) INIT, NEXT, MAXEXT, PCT, INDEXSPC

34

Default -v- Override parameters

• Overrides in application designer

35

How is the DDL/Overrides stored?

• Space Model

• Default Parameters

• Record & Index Parameter Overrides

36

DDL Model

37

Default Parameters

40

Two Data Dictionaries

• Compare– Database Catalogue

PSIDXDDLPARM

41

SQL Optimisation

• Tracing– Extract SQLcleanup.exe

– replay

• Mass Change/AE/Cobol• SQR

42

Enabling Tracing

45

Mass Change/AE/SQR

• What you see in the code is what you get– All PS programs can be traced

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

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 (<sid>,<serial#>,TRUE);

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

Set trace in session

• 2-tier client is multithreaded• Small Private Application server

– EXECUTE sys.dbms_system.set_sql_trace_in_session (<sid>,<serial#>,TRUE);

50

Backup Consideration

• Connected Processes– Application Server

– Process Scheduler

– Batch Programs

– 2-tier users

51

Performance Metrics

• Process Scheduler Table– PSPRCSRQST

• Trigger to capture history
