Well you just need to tell swremove which release of perl you want to remove, so:

swremove perl,r=5.3.4.1

should do the trick

Although I wonder why you don't just play with your PATH environment variable to remove the location of the older version from your search path (and you may possibly need to add the newer version in as well if it isn't already on there).

[Patrick Wallek]

The other issue you may have when attempting to remove PERL is applications that depend on it.  There may be A LOT of HP-UX that depend on one, or both, versions of PERL.

Here is output from the 'swjob' command of an swremove I ran on one of my test systems to remove PERL.

# swlist | grep -i perl
perl E.5.8.8.M Perl Programming Language
perl 5.10.1 perl

Hello Patrick Wallek,

As the error shows , multiple software such as HP9000Containers,DSAU.,Bastille installed  in server depends on Perl software you are trying to remove. You may forcefully remove perl using the option -x enforce_dependencies=false, but it may affect the functionality of other software mentioned above .

[Patrick Wallek]

Yes, I am aware of all of that.  That is the point I was trying to make to the OP.   If Java is removed it may affect other things on the system.

Hello satha,

The message you have tells that the software is not available for removal .

Please run swlist and confirm if you have software showing .

Hello satha,

As per swlist, the version available is E.5.8.8.O, , but perl -v showing otherwise .

$ perl -v

This is perl 5, version 34, subversion 1 (v5.34.1)

Swremove complaining that version 5.34.1 is not available for removal .

Have you removed perl version 5.34.1 earlier , which may be un-successful ?

You need to go through swagent.log and confirm the steps taken already .

@georgek_1 

I removed using the below  command 

swremove perl,r=5.34.1

  after that, I ran swlist and it was showing only E.5.8.8.O, but when I check for the version using Perl -v it is again showing 5.34.1

[georgek_1]

Hello Satha,

As mentioned , you need to check swagent.log carefully and see why the OLD perl version is showing though you have removed the version using r= with swremove .
