Alter TableSpace <Tablespace_name> begin backup;

Copy ‘filename’ to destination

Compress –f filename

Alter TableSpace <Tablespace-name> end backup;

Copy init and create cibtrik file also

Alter database backup control file to trace;

7) Copy files from source to target using scp scp –p *  <Servername>:/u12/app/oradata/sc03

Then enter unix password for unix oracle account then all files will be transferred.

8) Copy all archive files from begin and  end backup timeframe from source to target using scp

scp –p <required files>severname:/u06/app/archive/sc03ps03/arch.

9) On target sever change name of oradata using script file to reflect target database name in the filename rather than the server name.

10) On target server change names of archieve files t reflect target database name in the filename rather then the source name.

11) Recover the target database using an incomplete cancel based recovery using the backup controlfiles.

Connect internal;

Startup mount;

Alter database recover automatic using backup controlfile;

Alter database open resetlogs;

12) Rename the database name

create controlfile reuse set

database target databasename ,reset logs archieve logs.

Logging the change the names of log file.

Select global_name from global_name;

13) Alter database rename global_name to target_global_name.

14) Create temporary table space.

15) On the target database change the dbname inside of the PSDBOWNER table to represent the SID of the target database.

Initially after the refresh this PSDBOWNER will be set to the dbaname of the source database and the application will not start.

16) On the target database delete the data from three tables.

Ps_cdm_dest_node

Psprdmcntprv

Ps_serverdefn and commit.

17) Run the datamover script below against the target to restore the data you backed up.

27) What are the steps of peoplesoft installation of oracle on sun solaris 9 oracle? 

Login in as root and do the following things:

  • Mount the disk1 on your unix server

Enter the disk1 cd in your cd-rom and type mount to verify that it is mounted.

  • Copy the oracle software from cd to hard disk for example

su-oracle

mkdir –p/psdata1/ps/oracle/disk1

mkdir –p/psdata1/ps/oracle/disk2

mkdir –p/psdata1/ps/oracle/disk3

cp /cdrom/disk1/psdata1/ps/disk1

cp /cdrom/disk1/psdata1/ps/disk2

cp /cdrom/disk1/psdata1/ps/disk3

  • The installation requires a few environment variables to be set before it starts .These variables can be set into one’s profile directory by putting the lines.
Also Read:  Learn Building Dynamic Websites from Harvard Extension School

Please set these variables in /etc/profile

ORACLE_BASE = /oracle

ORACLE_HOME =/oracle/app/oracle/product/9.2.0.4.0

ORACLE_SID = PSCRMDEV

PATH =$PATH :$ORACLE_HOME/bin.

LD_LIBRARY_PATH =$LD_LIBRAR_PATH:$ORACLE_HOME/lib32:$ORACLE_HOME/network/lib32

Export PATH ORACLE_BASE ORACLE_HOME

ORACLE_SID LD_LIBRARY_PATH.

  • Create group dba,oinstall,oper

groupadd dba

groupadd oinstall

goupadd oper

  • Create user called oracle in which user account you will be installing the software.

Useradd –c DBA –g oinstall –G DBA –d /oracle oracle

Useradd –c ps –g oinstall –G DBA –d /ps ps

Password oracle=oracle

Password ps=ps

  • Target server create the following two files

/etc/jpst/equeus

add+cd $home

ui.rhosts add + open all rhosts and rusers.

  • Change the group of following slices to the oracle i.e. DBA

chgrp –r DBA /oracle/psdata1/psdata2;

chgrp –r DBA /oracle/psdata1/psdata2;

  • Following are lines you would add to the /etc/system file to configure the unix kernel and semaphore parameters.

Set semsys:seminfo_semmap=512

Set semsys:seminfo_semmni=512

Set semsys:seminfo_semmnu=4096

Set semsys:seminfo_semume=20

Set semsys:seminfo_semmnx=4096

Set semsys:seminfo_semmsi=256

Set shmsys :shminfo_shmmax=4294967295

Set shmsys :shminfo_shmmin=1

Set shmsys :shminfo_shmmni=300

Set shmsys :shminfo_shmseg=200

set shmsys :shminfo_msgseg=32767

Set shmsys :shminfo_msgmap=131072

Set shmsys :shminfo_msgtql=131072

Set rlim_fd_cur =1024

Set rlim_fd_max=1024

  • Restart the server to get changed   into effects:init6
  • Now login as oracle and start the installation process:

$cd /psdata1/ps/oracle/disk1./runinstaller.

  • It will start the installation by executing this file &answer appropriately to complete the installation in between it asks to run some scripts using root user that you can run with other telnet session.

To create oracle DB or install client on unix please following steps.

We have to follow this step this is very important.if we don’t do this all the inventory files will be written to the same directory and there  is a chance for them getting over written.(entry is oralabfile,ORTP:u01/app/oracle)

1. Goto /var/opt/oracle and see if there is any file with <SID_name>inst.loc.ifnot there we have to create it.

2. To create these fies,goto /usr/local/bin and search for root* we will see a bunch of files.locate root_oui_crlocfiles and root_oui_setlocfile

3. To run these files you have to root previlages or you can sudo to root also.

4.run sudo root_oui_setlocfile<SID name>-this script will create the DB specific orainst.loc (example:sudo root_oui_crlocfiles BDOPFT1.)

5.once the above script is complete,then run the second one.run root_oui_setlocfile<SID name>-this script will setup righ ora install and inventory location(example:sudo root_oui_setlocfile BDOPFT1)

28)  Installation of oracle patch on sunsolaris.9.2.0.1.0 to9.2.0.4.0? 

These steps is basically used to upgrade the database from 8.1.x to8.1.7.4 for seen solaris(64 bit database)

  • The x-server software (exeed ,or vnc)should be installed on your PC.(if you use VNC,VCN server software should be installed at server side &thin version clientof CNV  should be at PC).
  • Check whether you are able to make connection to server with VNC software.
  • Set DISPLAY =ipaddresss :0.0(ipaddress is the ip of pc)
  • Check xclock,xhost +commands
  • Take the complete backup of the database.
  • Take backup of oracle home and orainventory directories.

PIA: PS internet architecture is a combination of two servers i.e web server, application server that can be installed on a single server as separate system PIA is really an architecture without a client. No executable on client, it is more server centric.

PSDSTSRV:This is the distribution agent this program is responsible for copying completed process files from the process scheduler server to the report repository on the web server.

42) What are the Application server processes?

TUXEDO Process: a)BBL b)WSL  c)WSH
BBL: Bulletin Board Liason, Bulletin Board Liason is the main Tuxedo engine unless the BBL is loaded nothing on the Application Server will work. It also direct all communication traffic sending data request to the appropriate to process.
 WSL:  WorkStation Listener. The WorkStation Listener  process monitors the network for connection requests sent from windows clients.  Once a connection is established, the WSL hands the client to a WSH process to handle the ongoing communication.
WSH: The workstation handle maintains a persistent connection to the windows client until request for data have been satisfied. 

JOLT Process: a) JSL b) JSH

 JSL:  JOLT Station Listener–>The Jolt Station Listener process monitors the network for connection requests sent from Java clients (typically processes running on web servers). Once a connection is established. The JSL hands the client to a JSH Process to handle the ongoing communication.
JSH:  JOLT Station Handler. The Jolt Station Handler maintains a persistent connection to the Java client until requests for data have been satisfied.  The BBL tells the JSH which People Soft process is appropriate one to use.
PeopleSoft processes are designated to communicate with the database at the direction of the WSH. PeopleSoft processes query the database for data and object using SQL.

Different processes and their uses:

a)   PSAPPSRV : Peoplesoft application server process builds and saves html pages, runs People Code, processes messages, and handles most client SQL requests.  PSAPPSRV also performs user authorization duties when clients initially log in.

 b) PSSAMSRV: Processes conversational SQL transactions, primarily for the  application Designer development tool. 

 c)  PSQRYSRV: Specialized process that handles all SQL generated from the People Soft Query tool.  When this server does not need to be started for the domain to run, not having PSQRYSRV configured can lead to poor performance. 

d)  PSQCKSRV: Specialized process that handles all shorter, read-only client SQL requests.  This server is not currently used by the PIA client, and does not need to be started for the domain to run.

 e)   PSOPTENG: poeplesoft optimization engine. For optimization – based application functions, such as Consultant Scheduling, Supply Chain Planning, etc.

 f)  PSPUBDSP/PSPUBHND: The Publication Dispatcher (DSP) and Handler (HND) are responsible for publications-outbound messages from the Integration Broker environment – formatting the information and routing it to proper external systems.

 g)  PSSUBDSP/PSSUBHND: The Subscription Dispatcher (DSP) and Handler (HND) are responsible for processing subscriptions- in bound messages from external systems-bound to this system.

h) PSDBGSRV: Supports People Soft PEOPLECODE debugging sessions.

i) PSBRLDSP/PSBRKHND: These are the servers that manage Integration Broker queues, the dispatcher (DSP) picking up requests passing them to the handler (HND) which determines the type redirects the request to the proper queue for further processing.

43) What are the process schedular processes?

 A process scheduler domain included either two as three processes, depending on how it is configure.

BBL: The tuxedo bulletin board liasion is required for all domains whether they are for application server process or process scheduler server.

PSPRCSRV: This is the executable that we launch to start the process schedular server.it is the same program we have been starting with PSADMIN. the differnence now is that we will have tuxedo launch and then monitor the program for us.

PSDSTSRV: This is the distribution agent, this program is responsible for copying complete prcess files from the process schedular server to the report the repository on the webserver.

44) How can we connect to PS database in 2 tier mode?

45) What is database tables ?

1.system catalog tables: is like contents of books or FAT on a hard disk.

The system catalog tables keeps tracks of all the objects resides in the database instance.

System catalog tables means meta data that means data about data.

Examples: syscolumns, systables

2.people tool tables: the people tools tables holds metadata about the PeopleSoft application database.contains the structure that application use to define objects. The structure of the tables is the same for all  application.

PSMENUDEFN,PSRECDEFN, PSPNLDEFN contain column that used to define the navigation for an application(menu name, menu label , group it belong, version number)

The PT tables define the structure of all objects that make up the applications. The contents of the tables are filled in by the specific application installed. The naming convention used for PT is PS* PSRECDEFN,PSMENUDEFN,PSPNLDEFN.

3.Application data tables: Application data tables contains data entered for use by the orgaization. During implementation they are empty. the naming convention used or application data table in PS_*.

46) What is a Datamover tool, what is it used for?

Datamover is used to run DDL(create,alter,drop,grant), DML(insert,update,delete,commit,rollback)

There is no select statement

STANDARD: Set input/output/log/start/import/export/replace –all/replace-view/encrypt-password/rename.

1. datamover is use to perform large data load.

2. runs data conversion scripts.

3. data mover is good for creating views.

4. its has bulk load capacity.

47) APPLICATION DESIGNER?

Application designer is an online tool. Used to manipulate Peoplesoft defined objects with in a particular database. It is also used to import project from a file or form another database. General and process SQL scripts based on contents of a project.

To perform the compare and copy phase where the target and source database are compared and object moved from the source to the target. You can define following objects: Fields, records, page, component, menu, Style sheet, SQL, image, HTML, project, Application engine, business process, component interface.

48) What are the steps for building an application?

1. define an application.

2. create field definition.

3 create record definition using the field.

4. create SQL tables

5. create page.

6. create component.

7. create menu.

8. create permission list.

9 create role

10. Authorize operator to access role.

11 test.

49) Walk through process of migration objects from one environment to another with consideration for recover ability of environment should the migration fail? 

We use AD  to perform the compare and copy phase where the target and source database are compared and objects moved from the source to the target.

Application designer upgrade tools compares the source  and target objects for example when comparing two field definition the system will look  to see if the (field type,length,names e.t.c) matches if yes no action

If no, both version are placed in your comparison project and the appropriate default action is set. Then object starts (audit flags)

Unknown: The object has not been compared this is the default status for all objects inserted manually in to a project and he permanent starts of all non comparison  object.

Absent: the object absent in any one of the database.

Changed: PeopleSoft modified the object since the comparison releases.

Unchanged: PeopleSoft last modified the object previous to comparison release.

*Changed: You modified the object since the comparison release

*Unchanged: you modified the object prior to the comparison release.

Same: Same in both database.

PSSTATUS: Tools release info.

PSRELEASE: App release info.

PSLOCK: object version.

ACTION:

COPY:  object will be copied the target database.

DELETE: object will be deleted from  the target database.

NONE: App

COPY PROP: Migration update is used to find out PT objects not matching in PS Object (same like sysaudit)

1. launch on the B database.

2. create a new project in the AD  by selecting file > New> Project.

3. select your report option Tools upgrade options.

4. you will be prompted with PeopleSoft sign on for the target enter you I database.

5. decide which audit flags and DDL you wish to use.

6. compare application ,compare type-database/project.

7. target orientation : PeopleSoft vanilla, keep customization.

8. compare language  9.compare 10. report output 11.people code report 12.report filter 13.copy.

14. to  see your project file save project running compare reports.

Select Tools > upgrade > compare and report.

15. select the object you want to compare by default it     .

menu name , menubar name ,item name , languages, source, target,  upgrade.

50) How to  update people tools database objects?

Launch AD . Choose Tools > copy project > From file &copy. 

51) How to delete people tools database object?

Launch AD. Tools > copy project > from file.

52) Altering people tools tables or build a process?

1. launch people tools and singn on the installed database.

53) Why build from oracle  /created so that definition will be stored in system catalog table?

Write alter command to scripts,drop column. Drop column if data present  skip record.

Alter any (add,  change, rename, delete).

Alter even no change.

Table creation option : recreate table if already exist  ,skip table if already exist .

View creation option: recreate view if build already exist, skip table if already exist.

Index create: run, skip.

Running version application engine program

Psae – CD<dbname> -CT oracle –CD <oprid> -cp <pswd> -R INSTALL –all versions.

54) Knowledge of big transaction table in PS-FIN suits ?

PS_JRNL_IN

PS_ledger

PS_JRNL_Header.

55) How to troubleshoot a SQR PROGRAM using DISPLAY?

Show command  -Debug x option is also there

How to run SQR :

PS_HOME\bin\SQR\Ora\SQEWZIFC – \PSoft\EP\SQR\PSSQR.IN–I ic :\psoft\epse\

-c:   same command keep.

-I: specify the directory will search for include file.

-f: report output will be sent.

-zif: SQR INITIALIZATION File

-keep : keeps the SQR files.

56) PS security ?

1. definition security – AD /Trace/Query

2. maintain security

3. portal security 

57) Difference between 7.5 x vs 8.x security?

In 7.5 menu can be linked to oprid and class of operator.

In 8 menu is linked to permission list and permission list is linked to role to user.

68) What are the criteria for performance?

1. ram available

2. disk space and performance.

3. processor speed.

4. network bandwidth.

5. used load

6. user behavior(how hard do they push the application)

7. total data load (the total size of the database growth)

69) Different types of files?

70) BATCH SERVER?

Matched very closely to the database server is the BATCH SERVER. the  batch server holds a number of pre- programmed processes and tools that allow it to perform common functions against a database without the need for user intervention.

At a minimum, it requires a connection on the same segment of a fast LAN. For fastest performance, the batch server can be installed on the same host machine that holds the database(s) it will connect to.

You may hear the  terms batch server, batch environment, and process scheduler used interchangeably. This  is not quite correct, but they are all very similar. We will cover the differences in these terms later.

BATCH SERVER COMPONENTS:

The component that make up a batch server will vary somewhat, depending on the jobs you need  it to perform.

OS: the batch server will run under windows or UNIX.

DATABASE CONNECTIVITY: the batch server accesses PeopleSoft database directly. It will require database client connectivity software to do this job.

71) What are the different type of users in PS?

72) UPGRADES?

73) How do you implement patches? And what is the lifecycle of the patches?

 74) What are the different modules of PeopleSoft which you are currently working?

Thanks for so much information and tutorial. Just I feel it is not proof read well and someone with limited knowledge of Peoplesoft can’t make out some sentences as they are abruptly grammatically missing something or make no sense. Will be nice if you proof read it and edit sentences more clear or Jr ot Mid Level Peoplesoft DBAs.
