7
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
8
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
9
Security
• PS database usually owned ‘sysadm’ or ‘sa’
– = root, sys, system
– The password to this account is the key to
the kingdom.
10
Tracing
• Tracing administered
via configuration
manager
– i.e.. via registry
11
PS/Query, Crystal & ODBC
• PS ODBC driver
– Only defined
PS/Queries can be seen

Tablespaces (Oracle)
• Installation Scripts
• Temporary Tablespaces
29
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
30
Space Management (Oracle/DB2)
• DDL models
• Default -v- Override parameters
• Feeding back reality
31
DDL Models
• System-wide default storage options
32
Parameters
• PeopleSoft Parameters
– Square Brackets
• TBNAME, TBCOLLIST, IDXNAME,
IDXCOLLIST, TBSPCNAME
• User Parameters
– ** delimited
• Delivered (Oracle) INIT, NEXT, MAXEXT, PCT,
INDEXSPC
33
Default -v- Override parameters

Mass Change/AE/SQR
• What you see in the code is what you get
– All PS programs can be traced
45
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
46
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);
47
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;
/
48
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);
49
Backup Consideration
• Connected Processes
–
–
–
–
Application Server
Process Scheduler
Batch Programs
2-tier users
50
Performance Metrics
• Process Scheduler Table
– PSPRCSRQST
• Trigger to capture history
