IBM AS/400 manual Compatibility, Running in the OPM, Default, Activation Group

Managing

Activation

Groups

If you create an ILE

RPG

program

with

ACTGRP(*NEW),

you

can

then

c

program

as

many

times

as

you

want without returning from earlier

c

each

call,

there is

a

new

copy of the program. Each new copy

data,

open

its

files,

etc..

However,

you

must

ensure

that

there

end the calls to 'itself'; otherwise you

will

just

keep

creating

n

groups

and

the

programs

will

never

return.

¹

*CALLER

The

program

or service program will be activated into the activati

the

calling

program.

If

an ILE

program

created

with

ACTGRP(*CALLER)

i

called

by

an OPM program, then it will

be

activated

into the OPM

vation

group

(*DFTACTGRP).

Running in the OPM

Default

Activation

Group

When

an

OS/400

job

is

started,

the system creates an activation grou

by OPM programs. The symbol

used

to represent

this

activation

group

i

*DFTACTGRP.

You

cannot

delete

the OPM default activation group. It is

the

system

when

your

job

ends.

OPM programs automatically run in the OPM default activation group. An I program will also run in the OPM default activation group when one of occurs:

¹The program was created with DFTACTGRP(*YES) on the CRTBNDRPG command.

¹ The program was created

with

ACTGRP(*CALLER)

at

the

time

of

program

ation and

the

caller

of

the

program

runs

in

the

default

activatio

that

you

can

only

specify ACTGRP(*CALLER)

on

the

CRTBNDRPG

command

if

DFTACTGRP(*NO)

is

also

specified.

Note: The resources associated with a program running in the OPM defa vation group via *CALLER will not be deleted until the job ends.

Maintaining OPM RPG/400	and	ILE	RPG		Program		Compatibility
If	you	have		an	OPM application that consists of several RPG programs,
ensure that			the		migrated			application will	behave like	an OPM	one if y
ILE	application			as		follows:
1. Convert each					OPM	source		member using	the CVTRPGSRC	command,	making
	sure	to	convert			the	/COPY members.

See “Converting Your Source” on page 382 for more information.

2. Using the CRTBNDRPG command, compile and bind each converted source member separately into a program object, specifying DFTACTGRP(*YES).

For more information on OPM-compatible programs. refer to “Strategy 1: OPM-Compatible Application” on page 23.
