Migrating Connectivity Options

This section is relevant only for upgrades from a version of RSC that was not based on

Piccolo. See Determining the Appropriate Migration Section on page A-3 to determine

if an installation is Piccolo-based or not.

Prior to releases that included Piccolo, all connectivity information was specified in the

RSC.INI file or programmatically by RscSetOption. With the introduction of Piccolo as

the transport layer for RSC/MP, connectivity information is specified in the Piccolo

configuration file. As a result of the change in where connectivity information is

specified, existing installations must modify how connectivity information is specified.

There are two ways to change the connectivity information so it can be processed by

the Piccolo layer:

•

connectivity information can be moved from the RSC configuration file to the

Piccolo configuration file

•

RSC/MP can be run in a compatibility mode that passes connectivity information

through to Piccolo. This mode allows existing applications to migrate to RSC/MP

with no code changes.

The optimal method depends largely on how the connectivity information is specified in

the non-Piccolo installation. In situations where an applications’s connectivity

information is specified in the RSC.INI file, moving the settings to the Piccolo

Configuration file is recommended; in situations where the application uses

RscSetOption to specify connectivity options, compatibility mode is recommended.

Method 1: Moving Connectivity Settings to Piccolo

To move the connectivity settings to the Piccolo layer, do the following:

1. In the RSC.INI file, change the SUBSYSTEM_NAME to RSCPIPE.

2. In the RSC.INI file, add the HOST_PIPENAME option. See Step 4, Basic RSC.INI

Configuration on page 14-2 for information on setting this option and the resulting

behavior.

3. Update the Piccolo Configuration file with the connectivity information. See

Configuring the RSC/MP Transport (Piccolo) on page 5-1 for information on

configuring Piccolo.
