Overview
CA Service Management
 14.1.03 is an update for CA Service Desk Manager 14.1.x and installs the xFlow Analyst Interface Server and Search Server. The xFlow Analyst Interface offers a brand new experience for service desk analysts. For more information about how to install these components, see Install
CA Service Management
 14.1.03 (Windows/Non-Windows).
Installation Prerequisites
 Verify and consider the following prerequisites before installing
CA Service Management
 14.1.03:
  • Ensure that you have reviewed the Release Notes before you proceed with the patch installation.  
  • If you are deploying xFlow Analyst Interface with Apache Web Server on Windows 2012, update the 
    KB2999226
     patch for x64 Systems.
  • Ensure that your implementation has CA SDM 14.1 or above. The xFlow Analyst Interface server is deployed only on top of CA Service Desk Manager. 
  • If you are installing the xFlow Analyst Interface on Internet Information Services (IIS), complete the following steps: 
    Failure to complete these steps may result in
    login unauthorized
    error when you try logging into the xFlow Analyst Interface server.
    1. Install the IIS web server. 
    2. Open the command prompt and execute the following command to list the current MIME mapping:
      "%windir%\system32\inetsrv\appcmd.exe" list config /section:staticContent | find "json"
      If you get the following output, skip the procedure mentioned in step 3. If the command output is blank or empty, perform step 3. 
      <mimeMap fileExtension=".json" mimeType="application/json" />
    3. (optional) Enable the 
      json 
      MIME type :
      "%windir%\system32\inetsrv\appcmd.exe" set config /section:staticContent /+"[fileExtension='.json',mimeType='application/json']"
    4. To reset the IIS web server, run the following command:
      iisreset

How to Deploy
If you are installing
CA Service Management
 for the first time, a phased approach is recommended. Start with a small pilot group and add users and servers in phases. The following topics are described in this section: 
Deployment Guidance
CA SDM deployment model consists of the following categories:
  1. Small
  2. Medium
  3. Large 
CA SDM Advanced Availability configuration is recommended since it provides better performance and availability. Customers with less demanding needs can opt for CA SDM conventional configuration. Use clustered DBMS configurations to support large data volumes. Each server in advanced availability mode requires DBMS connectivity. 
It is difficult to give exact recommendations for deployment models since customers use CA SDM differently based on environment and organization requirements. Deployment model showcased in this article is based on feedback received from CA SDM customers, in general.
: If you are using a load balancer for Advanced Availability, ensure that the load balancer is configured to use sticky sessions.
The following diagram shows how to deploy CA SDM for small, medium, and large CA SDM configurations:

Install
CA Service Management
 14.1.03
The installer installs the following components: 
  1. The installer checks for CA SDM 14.1 and above in your environment and auto-upgrades to CA SDM 14.1.03.
    Install the patch on all existing CA SDM servers.
  2. Installs xFlow Analyst Interface Install the xFlow Analyst Interface on top of CA SDM 14.1 or above. Add a new secondary server for CA SDM conventional and an application server for Advanced Availability.
    Advanced Availability users can install the xFlow Analyst Interface only on an application server. 
    The new interface requires additional hardware resources and scales better horizontally. The main components of the xFlow Analyst Interface are a set of services (Incident, search, and notification services). These services share the default domsrvr out-of-the-box. For better performance, dedicate your domsrvrs for these services. From the CA SDM console, navigate to 
    Administration
    xFlow Analyst Interface
    General
     tab and update the following domsrvr variables: 
    • sdm.domsrvr.inms (for Incident services)
    • sdm.domsrvr.srms (for search services)
    • sdm.domsrvr.psms (for notification services) 
      You can provide multiple domsrvrs separated by a comma (,) for these services. After updating these variables, restart the xFlow Analyst Server services. For more information, see Configure the xFlow Analyst Server Services.
  3. Installs Search Server.
    Consider dedicating a server to install the Search Server. The search server has built-in clustering feature and can be installed on a standalone setup if your implementation has CA SDM 14.1.03. The recommendation for larger customers is that you install the search server on three or more servers and manually configure it to a fault-tolerant cluster.
