Creating custom TOP for error Inactive no manager

After cloning or upgrading if concurrent standard manager is not up with error "Inactive No manager".

Solution ->
Check whether custom.env file is there in APPL_TOP or not.
If not create a file named  custom.env like the following way ->

###################################
# Applications CUSTOM_TOP directory
###################################

CUSTOM_TOP=/other/testclone/TESTFFF/apps/apps_st/appl/XXFFF
export CUSTOM_TOP

XXFFF_TOP=/other/testclone/TESTFFF/apps/apps_st/appl/XXFFF
export XXFFF_TOP
###################################

Restart the apps server after sourcing APPS.env file.
