Depois de algum tempo alocado no cliente, finalmente consegui terminar e pedir aprovação e publicação deste Technote. Ainda faltam 8...rs!
Escrevi o artigo baseado no atendimento a um cliente, em Agosto passado (2012).
Depois de muito pesquisar nas bases de conhecimento IBM, cheguei à conclusão de que ainda estamos bem carentes de material do Archecker. Neste caso o cliente não conseguia restaurar e então validar uma imagem de backup.
Não sei se o link já está disponivel na internet, então ae vai o conteúdo:

Technote (troubleshooting)
Problem(Abstract)
When using Archecker to validate an IBM® Informix® archive backup
image, the following error message: "Unable to initialize resources" is
raised. This article describes the common causes and solutions for this
error.
Symptom
Starting the archive backup validation process leads to the following output:
$ archecker -tvs

CRITICAL ERROR: Unable to initialize resources.
Cause
The path /arc_ifmx set in the AC_STORAGE ac_config file has no proper permissions set so user Informix can read/write Archecker temporary files.
Diagnosing the problem
The ac_msg.log file provides more details about the cause of the problem. Most of the times the following error can be found:
ERROR: Error(2) Unable to create directory /arc_ifmx/SAVE
ERROR: Unable to initialize the save page section.
CRITICAL ERROR: Unable to initialize resources.
STATUS: archecker completed Setup pid = 17911 exit code: 3
Depending on the kind of syntax error, the following message may also be found in the ac_msg.log:
ERROR: Error(13) Invalid filename /tmp/SAVE/TP.0_1
ERROR: Failed to save page(0_1) in /tmp/SAVE/TP.0_1
ERROR: Unable to init for restart feature.
ERROR: Unable to initialize the restartable restore
ERROR: Device type not set properly
ERROR: No device driver selected.
STATUS: Scan FAILED
ERROR: Archive Physical Validation Failed.
The AC_STORAGE ac_config variable path do not have proper permissions:
drwxr-xr-x 2 root root 4096 Aug 24 08:18 arc_ifmx
Or even, when trying to use archecker '-d' flag to clean old temporary
directories CHUNK_BM, INFO and SAVE with wrong permissions:
dr--r----- 2 root informix 4096 Aug 17 14:44 CHUNK_BM
dr--r----- 2 root informix 4096 Aug 24 08:11 INFO
dr--r----- 2 root informix 20480 Aug 24 08:11 SAVE
Resolving the problem
Fix the AC_STORAGE path permissions properly.
STEPS
1. Add Read/Write/Execution permissions to others in the AC_STORAGE destination path directory:
$ chmod o+rwx arc_ifmx
or
$ chmod 777 arc_ifmx
2. Permissions should look like this:
$ ls -ltr
drw-rw-rwx 5 root root 4096 Sep 26 08:03 arc_ifmx
Críticas são bem-vindas.
Abraços pessoal.
