This page provides details on how to manage TrueSight Capacity Optimization at the operating system level.

Components of a TrueSight Capacity Optimization installation

The main components of a TrueSight Capacity Optimization deployment are:

  • Application Server:
    • Data Hub
    • Scheduler
    • Service container
    • Web server
  • ETL Engine
  • Presentation Server
  • Gateway Server
  • Database Server

Accessing the TrueSight Capacity Optimization machine

It is possible to access the TrueSight Capacity Optimization server via SSH (Secure Shell) using the account cpit.

To access the TrueSight Capacity Optimization database, ask the DBA for the TNS name configuration, then login as user CPIT_OWN (that is the owner of TrueSight Capacity Optimization schema).

Directory structure

The deployment is based on the user cpit. The entire TrueSight Capacity Optimization installation is contained in a single directory (usually /opt/bmc/BCO) called $CPITBASE.

The $CPITBASE directory contains one sub-folder for every TrueSight Capacity Optimization component installed on the system:

Folder Name

Component

datahub

Data hub

etl

ETL

scheduler

Scheduler

web

Web Console Application Server

If you install only the ETL engine or the Application Server a single machine only the sub-folders corresponding to the installed components will be present.

Into the $CPITBASE directory there are also sub-folders shared between different components:

Folder Name

Usage

resources

Common components and templates

repository

Content Repository (i.e. charts and reports)

The Content Repository directory contains charts and reports and can be used to contain data (For example, csv files) to be processed by the ETL engine: it has to be accessed in read/write mode by the JSP Engine and Primary Scheduler and in read mode by the Web Server. In case of a split installation (one server as ETL engine, one as Application server) the Content Repository directory can be an NFS (Network File System) mount point that maps an external storage, reachable by both machines.

The $CPITBASE also contains also some other sub-folders, used for installation and update purposes:

Folder Name

Usage

install

For installation packages

updates

For update packages

dbalignment

For DB schema update packages

Administrative procedures

The startstop, and restart procedures are managed with a single script, cpit, located in the home directory of each Application server where TrueSight Capacity Optimization is installed.
Only the installed components in each server are managed by the script.

In order to stop,start,restart all services, execute the following command from the home directory

  • ./cpit stop all: stop all services
  • ./cpit start all: start all services
  • ./cpit restart all: stop all services

Stopping and starting components

If you need to start, stop or restart a single component, execute the following command from the home directory:

  • ./cpit stop <component>: stop the web service
  • ./cpit start <component>: start the web service
  • ./cpit restart <component>: stop the web service

where <component> can be one of the following:

<component name>

TrueSight Capacity Optimization component

all

All components

datahub

Data hub

httpdApache web server

scheduler

Scheduler

servicecontainerService container

web

Web console Application Server

If you don't specify the component (i.e: you simply issue the command ./cpit start) this is intended as an all.

Checking logs

The standard out and standard error logs for TrueSight Capacity Optimization components can be found in the positions specified in the following table:
