Agenda

Some or all of the services described herein may not be permissible for KPMG audit clients and their affiliates. Code samples are presented as examples only. Sample designs are intended to represent observed good practices, and KPMG does not represent that these configurations are applicable to any specific client situation.

DevOps concepts for PeopleSoft

DevOps definition• IT cultural shift intended to improve collaboration across the service lifecycle• Dev = Developers, product managers, QA• Ops = System engineers, operations staff, DBAs, network engineers, security• Emphasizes people and process changes, not specific technology• Technology is used to facilitate DevOps concepts, but DevOps is not a technology

What is DevOps?

Goals:1. Deploy/refresh PS environments in minutes-to-hours2. Automate repetitive administrative tasks3. Empower developers to handle common tasks4. Standardize the process of releasing changes to production

The goal is to provide developers and testers a platform that is as similar as possible to production. — Load balancing – Use load balancer for all PIA domains— SSL/Certificates – Purchase (wildcard) certificates for all environments— DNS names – Match the DNS name to the environment name, e.g.,

fsdev.domain.com, hrtst.domain.com — Hostnames – Establish a naming convention for the servers, e.g.,

xxx-yyy#.domain.com

xxx = Region Membership = {DEMO, DEV, TEST, QAT, PROD, etc.}yyy = Server Role = {web, app, win}

Consistent setup between regions

Infrastructure designOrganize the PeopleSoft ecosystem

A region is a logical grouping of environments whose use is similar from a migration and testing perspective

etc...

Migration Path

Establish a consistent directory layout to facilitate automation of common tasks such as refreshes and patching. Security and segregation of duties can also be enforced via separate homes. — PS_HOME – Contains the PeopleTools 8.5x.xx binaries. Shared between multiple

application installations in a given region.— PS_CFG_HOME – Contains domain definitions (PIA, app server, process scheduler)

and logs— PS_APP_HOME – Contains all delivered, application-specific files. e.g., SQRs,

COBOL, Crystal reports, etc. — PS_CUST_HOME – Contains customized application-specific files

PeopleSoft homesDirectory layout

Each region would have an individually allocated disk with the following layout:/psft/middleware – WebLogic, Tuxedo, Oracle DB connectivity, and JRockit binaries/psft/psreports – Reports for all environments in the region/psft/pt855 – Contains the PeopleTools 8.55.xx binary files/psft/cfg/xx – All domain configurations: PIA, app, and process scheduler/psft/app/xx – Contains the delivered app-specific files (SQR, COBOL, Crystal, etc.)/psft/cust/xx – Customized app-specific files (SQRs, inbound, outbound, COBOL, etc.)

NOTE: xx represents the application abbreviation, e.g., cs, hr, fs, ih…

The example above is for Posix-style file systems; Windows would follow a similar pattern.

* The demo environments do not include any customizations and therefore do not require a PS_CUST_HOME directory.

In this design, the shared disk is mounted on multiple servers. Reliability is the highest priority for the mounted file system.Options:— Highly Available NFS— Clustered File System such as Oracle Cluster File System (OCFS)— Elastic File System (Amazon Web Services offering with using EC2)

Migration Path

What are the most common DB tasks for PeopleSoft? How can a DB platform choice simplify operations?

Cloning:— Refresh one PS environment from another— Build new PS environments based on existing environmentsBackup/recovery:— Automate backups— Quickly restore databases after a failurePatching:— Applying periodic security patches— Minor version updates

Database tasks

— Oracle 12c multitenant: On premise installation or DBaaS from Oracle Cloud, AWS RDS

Clone in minutesGoal

Reference: Oracle Magazine April 2014: Oracle 12c Multitenant Overview: http://www.oracle.com/technetwork/issue-archive/2014/14-mar/o24asktom-2147206.html

Provision databases rapidlyExisting database architecture:Multiple steps to clone a database

Oracle multitenant:Single step to clone a database

Before After

— Database‑as‑a‑Service (DBaaS):- Oracle Cloud Database Backup: Tie into cloud backup with Recovery Manager (RMAN) for backup

and recovery- Amazon Web Services RDS: Take DB snapshots and spin up a separate instance- Microsoft SQL Azure: Take snapshots and perform point‑in‑time restore

Clone in minutes (continued)Goal

Simplify backup & recoveryGoal

— Oracle 12c multitenant: On premise installation or DBaaS from Oracle Cloud, AWS RDSBackup many databases as one

Existing database architecture:Backup multiple databases

Oracle multitenant:Backup one multitenant container database

Before After

— Database‑as‑a‑Service (DBaaS): Oracle Cloud, AWS RDS, Microsoft SQL AzureAll three DBaaS offerings offer automated backup scheduling and point‑in‑time recovery options

Simplify backup & recovery (continued)Goal

Simplify patchingGoal

— Oracle 12c multitenant: On premise installation or DBaaS from Oracle Cloud, AWS RDSManage many databases as one

Existing database architecture:Patch and upgrade multiple databases

Oracle multitenant:Patch and upgrade one multitenant containerdatabase

Before After

— Database‑as‑a‑Service (DBaaS):- Oracle Cloud Database:

— User‑controlled patching performed through the DB Cloud Service Console- AWS RDS (Oracle DB or SQL Server):

— Automatic application of minor‑version upgrades— User‑controlled major‑version upgrades

- Microsoft SQL Azure: — Patching handled by Microsoft Azure with no down‑time— User‑controlled patching options also available

Simplify patching (continued)Goal

Automation

Avoid repetitive manual tasks

Remember the first two goals:1. Deploy/refresh PS environments in minutes‑to‑hours, not days‑to‑weeks2. Automate repetitive administrative tasks

Automate PS build and patching

Starting with PeopleTools 8.55, Deployment Packages (DPKs) are the delivery mechanism.

PS code, middleware, and (Oracle) database can all be provisioned on bare metal or virtual servers via DPKs — Run from command line— Scriptable— Customizable— Controlled with Puppet

PeopleSoft deployment packages

The delivered properties used by Puppet are found in a series of psft_*.yaml files— psft_configuration.yaml: PS domain properties, PS users, passwords, etc.— psft_deployment.yaml: Properties used to deploy Tuxedo, WebLogic, Oracle DB

client— psft_unix_system.yaml: Set up OS users, groups, sysctl parameters, ulimit, etc. — psft_ses.yaml: Properties Secure Enterprise Search

DPK modifications

To modify default properties, change the file psft_customizations.yaml.— Example for Financials development (FSDEV) environment:peoplesoft_base: “/psft”db_platform: ORACLEps_home_location: “/psft/pt855”inventory_location: “/psft/middleware/oracle/oraInventory”oracle_client_location: “/psft/middleware/oracle/12.1.0.2”jdk_location: “/psft/middleware/jdk1.7.0_95”weblogic_location: “/psft/middleware/weblogic”tuxedo_location: “/psft/middleware/tuxedo”db_name:FSDEVdb_user: VP1db_user_pwd: <some‑pw>ps_config_home: “/psft/cfg/fs/FSDEV”ps_app_home:location: “/psft/app/fs/FSDEV”

DPK modifications (continued)

Reference: My Oracle Support Doc ID 1641843.2

PeopleSoft delivers Automated Configuration Management (ACM) to simplify the configuration of environments after a refresh.

Delivered templates include:— Integration Broker— Web Profile— Process Scheduler — SES configuration

ACM can be run via command line, enabling the configuration to be added as a scriptable step in a refresh.

Automate PeopleSoft configuration

The ACM templates and customized YAML files should be treated as source code (Infrastructure as Code) and versioned appropriately. This allows for tracking and replication of infrastructure setups.

Version control for ACM and puppet files

ACM-FSDEV.txt

ACM-HRDEV.txt

psft_customizations.yaml

ACM-HRTST.txt

ACM-FSTST.txt

Developer enablementAllow developers to do what they do best

Remember the third goal:…3. Empower developers to handle common tasks…

Developer enablement

— Problem:- Developers need to stage files or access files produced by PeopleSoft- Developers need to access trace files

— Options:- Establish a Samba server on the AppBatch to expose the inbound/outbound directories.

Developers can securely mount the Linux directories as Windows drives on their desktops and directly access files.

- Establish a periodic/cron job to move trace files (*.tracesql, etc.) every few minutes to an accessible location

Access to inbound/outbound directories, trace files

— Problem:- Developers/testers need to exercise outbound email functionality without sending emails to ‘real’

users— Option:

- Establish a distribution email list for PS developers- Create a Perl (or similar) script to act as a local SMTP server and change the ‘to’ address to the

distribution list before forwarding the email message- Run the Perl script as a service on a local machine- Point the app and batch domains at the local Perl SMTP server (psappsrv.cfg and psprcs.cfg)

See Appendix for an example Perl script

Intercept outbound PeopleSoft email

— Problem:- Developers have to request app domain cache clear

— Option:- Use PHP and a shell script to execute the psadmin utility command line option to clear cache:

PHP (clear-cache.php):<?php

$output = shell_exec(‘sh /home/psoft/clear-cache.sh’);echo “<pre>$output</pre>”;

?>Script (/home/psoft/clear-cache.sh):

#!/bin/shsudo -i -u psoft psadmin –c purge –d APPDOMAIN –noarch –log “cache purge”

Modify sudoers file (using visudo):www-data ALL=NOPASSWD: /home/psoft/clear-cache.sh

Facilitate app domain cache clear via web page

Change controlEstablish a reliable process to update production

Remember the fourth goal:…4. Standardize the process of releasing changes to production

Change control

The migration path is the ‘pipeline’ to production. Changes should only flow in one direction.
