Implementation - Deployment

• Methods of deployment– User PC– Network shared

(workstation install)– Terminal server– Web Deployment (ActiveX) (Note: this section is covered in detail in the

next presentation)– lookserver deployment (Note: this is covered in the lookserver training

module)

0. Approach

• Options Available– Program files are installed on the PC.– Program files are installed on the PC with updates ‘pushed’ out.– Program files are installed on the PC with SID on server.

Deployment – Local Installation

0. Approach

• All Program files on the PC

0. Approach

• Program files on the PC (cont.)– Pros

• All the files are executed locally therefore eliminating the reliance on a third-party server.

• Network traffic is minimized as communication will be via 5250 data streams to the iSeries.

– Cons• Any updates to program or data files will have to be applied

manually.

* Can still use nlupdate

Deployment – Local Installation

0. Approach

• Program files on the PC with updates ‘pushed’– Use ‘images’ with third party products from Microsoft and Novell.

‘Image’ Updates

0. Approach

• Program files on the PC with updates ‘pushed’ (Cont.)– Pros

• Files are executed locally. • Network traffic is minimized.• newlook maintenance is centralized for easier updates.• updates can be scheduled for quiet times.• End-user operating systems, drivers, virus definitions and third-

party programs can also be installed and updated ‘silently’.– Cons

• There is an implementation overhead associated with the initial loading of files on end-user PCs.

• Not every company has access to these tools or infrastructure.

0. Approach

• All Program files on the PC (except SID)– Pros

• All the files are executed locally therefore eliminating the reliance on a third-party server.

• Updates to the definition file can be applied centrally. – Cons

• The screen ID records within the SID file are loaded every time newlook is started. This could create an increase in network traffic if a large number of users try and log on at the same time.

• Any updates to program or data files will have to be applied manually.

– Variations• Custom Installation• Scripted Installation

Deployment – Local Installation

0. Approach

• Options Available– Program files are stored and executed from file server

(workstation/server install).– Citrix (or Windows Terminal Server).

Deployment – Network Installation

0. Approach

• Program files are stored and executed from file server (workstation/server install) (Cont.)– Pros

• All the files are centrally located and therefore easily updated. – Cons

• The program and SID files are loaded every time newlook is started. This will create a noticeable increase in network traffic if several users try and log on at the same time.

• End-User PCs are reliant on access to the third-party server to execute newlook.

Deployment – Network Installation

0. Approach

• Citrix (or Windows Terminal Server)

Citrix ICA Stream

0. Approach

• Citrix (or Windows Terminal Server) (Cont.)– Pros

• All the files are centrally located and therefore easily updated.• Support via Citrix for Mac, Java, PDA, Thin Client and Web delivery.

– Cons• The communications from the server will be full GUI frames and not

5250 data streams. As the GUI frames will be of a greater size than the 5250 data stream bandwidth requirements will increase.

• End-user PCs are reliant on the Citrix server and therefore if it is unavailable users will not be able to access the iSeries.

Deployment – Network Installation

• Web Deployment– Activated via the Internet browser, users download, install, and run

newlook by simply pointing their browser at a nominated web page.– The files required to run the ActiveX control are packaged into CAB files

& are stored on the web server.

Deployment –Web Deployment

Deployment –Web Deployment

• Web Deployment– Pros

• Installation can be unattended. Users click on the web page and the download of the necessary files takes place automatically

• Updates are automated. Each time a user starts the web page a check for newer files takes place.

• All the installation (CAB) files are centrally located and therefore easily updated.

• If the application has been downloaded previously then locally cached files will be used. Only updates that are made to the server will be downloaded.

– Cons• A browser supporting ActiveX controls is required.

• Deployment using lookserver– HTTP traffic between client and web server– Telnet traffic between web server and iSeries

• Deployment using lookserver– Pros

• Zero footprint so no download of program files is required• Will work across multiple desktop platforms. Only requires a browser

with XML support.• Will support mobile/PDA devices natively. • Updates are easy to deploy.

– Cons• Desktop integration not supported• Full rich client interface only available with smartclient.
