Middleware Use Cases
WebLogic Server 12c (WLS) version 12.1.1
Oracle Service Bus 11g (OSB) version 11.1.1.6
WebLogic Portal 10g (WLP) version 10.3.4
Small, Medium Or Large Deployment
14
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
15
Prerequisites
• Configure Software Library on OEM Server
• Enable passwordless (ssh keys) connection between Oracle
Management Service and new VM
• Update the /etc/sudoers with: weblogic
ALL=(root)/u01/app/Oracle/product/agent12c/sbin/nmosudo
• Setup named credentials and privilege delegation.
• Install required packages on the OS, create OS user and
group(webLogic)
• Install and start Oracle Management Agent on new server
16
Sample: Provisioning Profiles
17
Directives
• Provisioning Profiles Capture “Standard” Files and Artifacts of
WebLogic Domain[Gold Image].
• Additional Files Specific to WL Domain 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
• Be sure to check “Use Most Recent Version” check box, else your
procedure keeps calling older version
18
Sample Directive
19
Customized Deployment Procedure
Oracle-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}
20
Sample Deployment Procedure
21
Options to Provision
Provision using console:
• Several clicks and repetitive
process
Provision using EMCLI:
• Capture once and execute many
22
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
