Vertical and horizontal scaling in oracle EBS Application R12

-

 Vertical scaling (Scaling up)

 Adding more power CPU,RAM,DISK to your existing machine.

 In EBS R12 perspective  Adding more managed Servers to existing Node. 

1) Single Managed Server (oacore_server1) on OACORE_CUSTER_1 



    
2) Add Additional OACORE Managed Server  ((oacore_server2) on OACORE_CUSTER_1)


You can create Additional Manage Server using Tool adProvisionEBS.pl  

Why Additional Managed Servers 

  1. Handling Load and User Concurrency
  2. Provide Redundancy
  3. Add Services to existing  Node  (accessgate for SSO)

Horizontal scaling (scaling out)

Adding more machines to your pool or Cluster.

In EBS R12 perspective,  ADD Managed Server by adding  new Server to exiting Cluster . 

Horizontal Scaling 

OACORE_SERVER1 and OACORE_SERVER2 on OACORE_CLUSTER_1 but both managed Server deployed on  different Application Server  

You can Add Secondary Node on EBS Application using RAPID CLONE 

Why Multiple Server 

  1. Load Balancing 
  2. High Availability
  3.  Add Services  by Adding new Node (DMZ node for iModule,Dedicated CM Node,Mutiple Webentry Points)

Enabling TLS 1.2 with Backward Compatibility in Oracle E-Business Suite Release 12.2 using Elliptic Curve Cryptography (ECC) certificate

-

  Introduction TLS  Transport Layer Security ( TLS) is the successor  protocol to  SSL .  TLS  is an improved version of  SSL . Elliptic Curve Cryptography (ECC) certificate   ECC offers equivalent security with smaller key sizes, which results in faster computations, lower power consumption, and memory and bandwidth savings. Oracle Fusion Middleware supports the use of an Elliptic Curve Cryptography (ECC) certificate if the entire chain is ECC and the server cert is signed using ecdsasha256. Oracle E-Business Suite connections fall into the following three categories: Inbound connections Inbound connections are from a client to the Oracle HTTP Server (OHS) delivered with the Oracle E-Business Suite applications technology stack Example :  User accesses Oracle E-Business Suite applications pages through the network using a browser User accesses Oracle E-Business Suite application through Oracle Forms when using Forms Servlet mode An XML Gatew...

Due to data dependencies, scrambling E-Business Suite data is very time consuming and difficult task, because application functionality should work after Data Mask .  Oracle Provides Pre defined Data Masking Pack ( EBSMaskingPack 2.0.7) it is   Certified     with EBS R12.2 , We can easily do Data Masking on Test environment   using OEM 13 C with  Pre defined Data Masking Pack.    Data Masking Template certified with EBS R12.2 does the following. De-identifies the data : Scrambles identifiers of individuals, also known as personally identifiable information (PII).  Examples include information such as name, account, and address. Masks sensitive data : Masks data that, if associated with PII, would cause privacy concerns.  Examples include compensation, health and employment information.   Maintains data validity : Provides a functional application. Below Steps Demonstrate How to Mask -Oracle E-Bu...

Enabling SSL in Oracle E-Business Suite Release 12.2

-
Image
Oracle E-Business Suite Release 12.2 uses the Oracle Fusion Middleware infrastructure to secure communication between components using SSL (Secure Sockets Layer). Oracle HTTP Server (web tier) is the web server component for Oracle Fusion Middleware  and enables strong cryptography using mod_ossl and mod_wl_ohs modules. Web tier certificates can still be managed by   1)    Oracle Wallet Manager (OWM) GUI Tool 2)   orapki command line interface (CLI) 3)   Oracle Enterprise Manager Fusion Middleware Control (Fusion Middleware Control) Components running under Java  1)   JKS-based keystores to store keys and certificates. Set Your Environment for SSL  1)  You need to Configure SSL on RUN file System, So you require Application down Time  2)    Apply the latest AD and TXK Delta Release Update Packs (Always Recommend) 3) If you are using clients (JRE 8, some modern browsers) or Oracle Database 12c, you must ...
