Migrating Applications to TS/MP 2.3
and Later Versions
This section includes these topics:
•
TS/MP 2.3 Environment Similarities
•
TS/MP 2.3 Environment Differences
All TS/MP 2.0 applications that use Pathsend requesters and TS/MP configuration
scripts (also called
OBEY files) can run in a TS/MP 2.3 environment. However, to take
advantage of the new features and to understand slight differences in behavior, it is
important to understand the similarities and differences between the two versions of
TS/MP.
TS/MP 2.3 Environment Similarities
TS/MP 2.3 is similar to TS/MP 2.0 in the following ways:
•
You do not need to recompile the TS/MP 2.0 applications. However, applications
that manage configuration and operation of environments are an exception; you
might need to make changes as described in TS/MP 2.3 Environment Differences
.
•
You do not need to recompile even if you want to use the new Pathway domain
feature. Although the Pathway domain name syntax is different from a regular
PATHMON process name syntax, the applications need not be recompiled even if
an application wants to send a request to a Pathway domain.
If the send is being targeted to a specific PATHMON process that is made part of a
domain as mentioned in the
ACSCTL file, then the default behavior of TS/MP 2.3 is
that the send is targeted to the entire domain. However, you might want to
suppress this behavior and continue to send requests to the specific PATHMON
process by setting the
flags parameter as described in the TS/MP Pathsend and
Server Programming Manual.
•
The program file name and the process name remain unchanged. To provide
transparent migration for TS/MP 2.0 applications, the ACS subsystem link
management functions use the same system file name (
$SYSTEM.SYSnn.ROUT)
and process name (
$ZLnn) used by the TS/MP 2.0 LINKMON process. However,
because the contents of
$SYSTEM.SYSnn.ROUT are different for each version, the
TS/MP 2.3 version cannot be used in a TS/MP 2.0 environment, and vice versa.
Note. The migration details desribed in this section are applicable to TS/MP 2.3 and later
versions.
