Technote de Archecker ::: CRITICAL ERROR: Unable to initialize resources

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.
