Reclaim Resources Command

The

Reclaim Resources (RCLRSC) command is

designed to free the resourc

programs

that

are no

longer

active.

The

command

works

differently

depen

how

the

program

was

created.

If

the

program

is

an

OPM program

or wa

with

DFTACTGRP(*YES),

then

the

RCLRSC

command

will close

open files and

free static

storage.

For ILE programs or service programs that were activated into the OPM activation group because they were created with *CALLER, files will be when the RCLRSC command is issued. For programs, the storage will be re initialized; however, the storage will not be released. For service pr storage will neither be re-initialized nor released.

Note: This

means that if you have

a

service

program

that

ran

in

the

vation

group

and

left

files

open

(returning with

LR

off),

and a

issued,

when

you

call

the service program again, the

files

will s

be open,

so

so

any

I/O operations will

result

in

an

error.

For ILE programs associated with a named activation group, the RCLRSC command has no effect. You must use the RCLACTGRP command to free resources in a named activation group.
