We are currently migrating from aix7.2 to aix7.3

We would like to use the perl module Encode::JP::H2Z in our self-developed application, but it seems that it is no longer available in aix7.3.

In AIX7.2, it was located in /usr/opt/perl5/lib//5.28.1/aix-thread-multi/Encode/JP/H2Z.pm.

I looked in the rpm version of the AIXToolbox package, but the module was not found.

I also asked IBM support, but they replied, "As stated in the release notes, the Perl package provided by the OS may not maintain full compatibility across all versions.

However, the perl provided with the AIX OS is intended for use by the OS, and is not supported for use by users.

Therefore, we are very sorry, but we do not provide support at our office.

"

I'm sorry, but I don't understand the basics of Perl, but could you please tell me how to obtain the above module?

You can install the perl module using the cpan command. 
First, please ensure that xlc compiler is installed in the system and path to the xlc compiler is included in the PATH environment variable.
[For eg:export PATH="/opt/IBM/xlc/13.1.3/bin:$PATH"]
After this, you can execute the following commands:

export LDR_CNTRL=MAXDATA=0x80000000@DSA
/usr/bin/cpan Encode::JP::H2Z

Thank you for your answer.
I did some research myself and found out that I could install the module from CPAN.
However, the environment in question was not connected to the Internet, so I unzipped Encode-3.21.tar.gz downloaded from CPAN.

As a separate issue,
I tried making and making test to check where the module was installed, but I was unable to confirm the destination folder where the module would ultimately be installed. Is there a way to check this?
Or will it be placed in the default perl folder?

When "make install" is executed, the files will be installed in /usr/opt/perl5/lib/site_perl/5.34.1/aix-thread-multi path by default. 
You can also install it in a custom location using the command "make install DESTDIR=<newLocation>" . In this case, the files will be installed in <newLocation>/usr/opt/perl5/lib/site_perl/5.34.1/aix-thread-multi.

Hello, Takao San

I always share this information with application teams so they can consider different perl options in future releases.  This is of particular interest to applications that install modules to perl.

Thank you for your answer, Harris.

I think the perl install path will change if we install the toolbox version of the rpm package, e.g. /opt/freeware (I haven't tried this because I don't have a test environment at the moment).
In this case, depending on the coding of the application team, we would have to review the settings and environment variables, is this correct?
(e.g. coding with full path specification, etc.)

I prepared a verification environment and tested it

I got ESD-Toolbox_for_Linux_Apps_Common_7.2-7.3_062024_LKT010327.tar.gz from ESD since I can't access to the Internet.

# . /dnf_aixtoolbox_local.sh

# /opt/freeware/bin/dnf install perl

# which perl
/usr/bin/perl
# ls -la /usr/bin/perl
lrwxrwxrwx 1 root system 29 Aug 18 2023 /usr/bin/perl -> /usr/opt/perl5/bin/perl5.34.1

# perl -v

This is perl 5, version 34, subversion 1 (v5.34.1) built for aix-thread-multi
Omit the following

# /opt/freeware/bin/perl -v

This is perl 5, version 38, subversion 2 (v5.38.2) built for ppc-aix-thread-multi-64all
Omit the following

From the above
Is it OK to change the /usr/bin/perl link from /usr/opt/perl5/bin/perl5.34.1 to /opt/freeware/bin/perl_32bit (because the existing environment is 32bit)?
Or should I have the application team modify the program?
I'd appreciate it if you could enlighten me.

Hello Takao-San

You asked:

Is it OK to change the /usr/bin/perl link from /usr/opt/perl5/bin/perl5.34.1 to /opt/freeware/bin/perl_32bit (because the existing environment is 32bit)?
Or should I have the application team modify the program?

As noted in the previously mentioned technote,

Replacing /usr/bin/perl links with custom Perl installations can cause unexpected results for AIX applications, and is not supported.

Additionally, you would encounter issues during any subsequent updates, since the perl.rte update would replace your links.

It is best to handle this in the application level, then you have control over the updates.

I prepared a verification environment and tested it
