Middleware Use Cases

WebLogic Server 12c (WLS) version 12.1.1Oracle Service Bus 11g (OSB) version 11.1.1.6WebLogic Portal 10g (WLP) version 10.3.4Small, Medium Or Large Deployment

15

Prerequisites

• Install and start Oracle Management Agent on new server

• Install required packages on the OS, create OS user and group(webLogic)

• Enable passwordless (ssh keys) connection between Oracle Management Service and new VM

• Update the /etc/sudoers with: weblogicALL=(root)/u01/app/Oracle/product/agent12c/sbin/nmosudo 

16

Middleware Provisioning

• Discover reference Oracle Home/domain

• Create provisioning profile in software library

• Create directives in software library

• Edit predefined deployment procedure

• Test deployment procedure from console to capture input parameters

• Create wrapper script which calls emcli “submit_procedure”

• Enable end users to make requests using PG&E’s Provisioning Portal

17

Provisioning Profiles

18

Directives

• Provisioning Profiles Capture “Standard” Files and Artifacts of WebLogic Domain.

• Additional Files Specific to Line of Business must be moved to Target Host(s) with File Transfer Step or Directive.

• With Directives you upload required Files to Software Library along with script to move and/or Manipulate Files, called Main file

• There are other uses for Directives. However, this is how we primarily used them

• Be sure to check “Use Most Recent Version” check box, else your procedure keeps calling older version

19

Sample Directive

20

Customized Deployment ProcedureOracle-provided deployment procedure named "Provision Middleware" customized to accommodate PG&E requirements Custom Directives (Described Earlier), or Shell Script that Execute Shell Commands and/or call WLST We Generally Added One Directive and 3 to 4 Shell Scripts to Customized Procedures Shell Script Cannot Exceed 4096 Characters. Can Use Runtime Variables in Scripts, e.g. ${target.DOMAIN_HOME_DEST_ADMIN_HOST} Steps Can Have Conditions (e.g. execute only on remote servers)

21

Sample Deployment Procedure

22

Options to ProvisionProvision using console:• Several clicks and repetitive

process

Provision using EMCLI:• Capture once and execute many

23

EMCLI Wrapper Script• Generated Properties Files Made Generic by Substituting Actual Values with

Specific Keywords:

<Hostname> -> MyHostName <Domain Name> -> MyDomainName <DBSid> -> MyDBSid

• Wrapper Scripts Creates Copy of Properties Files and Substitutes New Values Passed on Command Line

• Removes Copy When Completed

• Provision New WebLogic Portal Domain Example: sh ./emcliWrapperDB.sh "DB_DATA" "S" “database-host“ "Linux" "WLPDBS" sh ./emcliWrapperWL.sh WLP S EIWLP wlp-mw-host database-host WLPDBS
