LANDP set up on Linux
ehcsetupPerforms several necessary steps:
Directory creation;User creation;Environment set up file (.ehc_profile);
Must be run by a super user, normally root.
Typical directory structure, as created by ehcsetup.
/opt/ ibm/ landp/
l60/ - LANDP Release directory bin/ - LANDP Binaries lib/ - LANDP Shared Objects/Libraries msg/ - LANDP Messages S1/ - LANDP Workstation directory

LANDP set up on Linux
Groups and UsersLinux uses groups and users to manage access to resources.
LANDP for Linux requires all users, that will use LANDP, to belong to the landp group to gain access to LANDP resources.
On Linux a user can belong to many groups. When loading LANDP the user’s primary group must be landp.
.ehc_profileCreated by ehcsetup.
Contains statements to set environment variables: PATH, LIB and so on.
We recommend that each user’s profile calls .ehc_profile.

Migrate to Linux
Three main building blocks of migration:
LANDP Workgroup Configuration
Customer, and third party, Software
Customer Data

Migrate to Linux
LANDP Workgroup Configuration
Update SPC files, COMMON, LANCONF
Run Valspec and Genrun
Distribute to ‘temporary’ location
Run ehcsetup
Set environment (.ehc_profile)

LANDP for Linux Demonstration
Migrate a 2 workstation, S1 and C1, workgroup:Windows Platform;
NetBIOS;
Shared File Server on S1;
SVPCPRBN; and
EHCTRACW.
Demonstrates:Changes required to configuration files;
ehcsetup – post distribution steps; and
SVPCPRB on Linux (SVPCPRBL).

Recap
LANDP Version 6 provides support for Linux
When migrating your configuration:Update paths defined in SPC files.Update LANCONF to:
reflect the correct workstation type;use the TCP/IP transport (XPORT
keyword); andobtain the correct user defined software
packages.
When running your LANDP for Linux configuration:The user’s primary group must be LANDP; andThe environment must be correct, use .ehc_profile,
