Seagate Info Report Writer


In general Seagate Info will manage and produce web-based reports from a database engine. Included is full application server based security features plus server produced reporting editing, scheduling and production facilities. Also Seagate Analysis can be used to do OLAP processing (Online Analytical Processing) of multi-dimensional cubes on reports produced by Seagate Info.

Seagate Info does appear to be extremely scalable by use of clustering of NT-Server machines. However, it is possible that too much clustering could lead to serious speed problems.

Seagate Info appears to have a pricing structure which may not be competitive with other products such as Actuate. Actuate charges by Power Units (based on CPUs) and Seagate Info charges based on numbers of concurrent users. For very high activity web sites, Seagate Info could be as much as ten times more expensive than Actuate.

Users

There are multiple levels of security.

  1. Adminstrators.
  2. Designers - excludes only administration privelages.
  3. Schedulers - generally users who allowed to execute as well as run reports.
  4. Viewers - users who can view previously scheduled and executed reports only.

Sentinel

The Sentinel is a server and client Seagate Info listener process in a client-server environment. Browser accessing clients do not require the Sentinel process.

Info Desktops - Available Options

Info Desktop

Info Desktop is a client installed desktop program allowing access to reports based on access privelages. This program can also be executed from within a browser which may require initial ActiveX object (or equivalent) initial download.

The Select and Search buttons are only available if you are using Microsoft Internet Explorer 4.0 or higher. These buttons are not available while using any Netscape browser. If you are running the new Custom HTML desktop with a screen resolution lower than 800x600 the full range of toolbar icons will not appear.

Info WebAccess

Have both HTML and Java broswer based desktops with almost all functionality of the Info Desktop for Windows. Allows the following options from the browser.

The four types of Info WebAccess.

  1. Info Desktop for HTML standard


  2. Info Desktop for HTML Custom WebAccess


  3. Info Desktop for Java


  4. Info Channel

Some Different Installation Configurations

Info APS + Info Report Server + Info OLAP Server + Info Desktop(s)

You may have multiple users connected to a single Info APS to share information. The Info APS and Info Server are on the same machine and other client machines over a network have Info Desktop only. Centralised reports are shared and database connections are minimised since only report executing machines require database connections.

Info APS + Info Servers(s) + Info Desktop(s)

Here we have more than one Info Server. Info Servers are used on a first available basis, all at once or as a user chosen Info Server. Diferrent servers can be dedicated to specific functions such as viewing servers, Info OLAP servers and report processing servers. This configuration allows for distribution of report and query processing and can be used for multiple database installation environments.

Info APS + Info Server(s) + Info WebAccess Server

Here we provide access to Info APS from web browsers. No client machine software is required, ie. Seagate Desktop. This configuration allows for cross-platform support, is independant geographically and there is no client software requirement.

Info APS Cluster + Info Server + Info Desktops from Network

Allows for the maximum work sharing of Info APS functions, reporting, querying, OLAP cubes and scheduling. Info APS servers can be on clustered machines acting as a single virtual APS server. This is scalability in the extreme in terms of processing power and number of users. Another benifit in this case is robustness as a result of cluster machines failover where if one machine fails the others are still available. This is called high availability. Obviously the network will have to be scaled relatively to cope with the additional communication between clustered machines. On the contrary, it has been said that Seagate Info suffers significantly in performance in a clustered machines environment.

Standalone

In this case all components are installed on a single machine. Even a database could be installed on this single machine. This environment is useful mostly as a test environment where administration is simplistic and all components reside on a single machine. Obviously this environment is perfect for a company wth only standalone requirements.
