spaces replaced by __20 after pathworks upgrade

robert70 — Mon, 08 Nov 2010 09:31:27 GMT

Upgraded Pathworks from 6.0c to 7.3B and files created by word *.docs are now showing this type of changes

before upgrade:-
various upgrade notes.doc

after upgrade:-
various__20upgrade__20notes.doc

can anything be done to resolve this? apart from obviously changing each file manually.
thanks

also odd things happening with long named files after upgrade (also upgraded vms 7.3-2 to vms 8.3)

doing a directory of files we have

before upgrade:-
QUESTIONNAIRE_ADDITIONAL_NOTES_29-2017.DOC

and after upgrade:-
QUESTIONNAIRE__20__28ADDITIONAL__20NOTE.S__29__20-__2017__2E02__2E00__2EDOC

?

ODS5 disk?

Re: spaces replaced by __20 after pathworks upgrade

robert70 — Mon, 08 Nov 2010 12:23:01 GMT

AHH YES JUST UPGRADED THIS TO AN ODS5-DISK
does this have limitations on length of names?

Re: spaces replaced by __20 after pathworks upgrade

Ian Miller. — Mon, 08 Nov 2010 13:07:04 GMT

no, the opposite - ODS5 has allows a greater variety of names.

However you may need to tell Advanced Server to act differently.

(BTW do you have V7.3B ECO2?)

Re: spaces replaced by __20 after pathworks upgrade

NO ECO2
just 7.3B

Hello Robert,

Back in the day, I used to wonder why we wrote documentation - folks never read it I thought. And they still don't read it, apparently. ;^)

Seeing as you installed V7.3B, I think it appropriate to point you to the V7.3B Server Installation and Configuration Guide. You'll find it at http://h71000.www7.hp.com/doc/82final/6540/6540pro.html.

In particular, read Chapter 5.8 - "Converting Encoded File Names from ODS-2 to ODS-5".

You see, ODS-2 does not support extended file names and things like spaces in file names. So, PATHWORKS and Advanced Server will encode the non-ODS2 compatible characters in a file name by replacing them with __XX where XX=ascii hex value of the character. for example, a space in a file name is encoded as "__20" (that's underscore underscore two zero).

Now that you converted the disk to ODS-5 and ODS-5 supports the extended file names, there is no need for the encoding and Advanced Server assumes there is no encoding. So when it sees "__20" it no longer changes it to a " " (space), it leaves it as "__20" which is exactly what you see.

You need to run the PWCONVERT utility against the disk to get rid of all those encoded characters.

Hope this helps,

This does not make sense:
>>before upgrade:-
>>QUESTIONNAIRE_ADDITIONAL_NOTES_29-2017.DOC

>>and after upgrade:-
>>QUESTIONNAIRE__20__28ADDITIONAL__20NOTE.S__29__20-__2017__2E02__2E00__2EDOC

Are you showing us what the client PC sees, or what you see from VMS?

Did this disk get converted from ODS-2 to ODS-5?

"QUESTIONNAIRE_ADDITIONAL_NOTES_29-2017.DOC" is a legal ODS-2 file name. There should have been no encoding for that file name which is why I say something doesn't make sense with regards to that name.

Are there many other files like that one?

Sorry Brad this was showing

QUESTIONNAIRE ADDITIONAL NOTES 29-2017.DOC

before the upgrade

>>Are you showing us what the client PC sees, or what you see from VMS?

this is showing both what the client sees and what vms sees - both the same

It was the system disk that was upgraded from ODS2 to ODS5 - the user disk which contains the files mentioned above were already ODS5

>>Are there many other files like that one?

There are many files yes

i get a failure when using pwconvert on a file that has had its name changed - see above

Re: spaces replaced by __20 after pathworks upgrade

robert70 — Tue, 09 Nov 2010 08:36:33 GMT

obviously because the disk which has corrupted file names was already ODS5 I am getting this on a pwconvert also.....

$pwconvert *.*

File is not ODS-2 - $1$DGA1:[PCCOMMON.FAQ]FAQ__20001__20-__20157__20__20INDEX.DO
C;1

etc...........

Robert,

You should have run this command right after the upgrade.
Now several files have been touched by Advanced Server and now have an ODS5 header.

There are 3 undocumented switches to overcome this issue.
If either of the following checks fail, PWCONVERT refuses to perform a conversion.
- Is the device ODS5 ?
- Is the file's fileheader NOT already an ODS5 type?
- Does the file have a Pathworks ACE ?

This can be bothersome. Accessing a file (even a $type command) may already be enough to have OpenVMS automatically change the fileheader layout from ODS2 to ODS5.

Each of the above checks can be overruled with the /DISABLE qualifier:

$ PWCONVERT /DISABLE=(ods5, struct, ace)

where disable=ods5: do not check if the device is ODS5
disable=struct: do not check if the fileheader is ODS5
disable=ace: do not check if the file has a PWRK ace.

Normally it will suffice to use /DISABLE=(struct) or /DISABLE=(struct,ace).
Using /DISABLE=ods5 is not recommended.

Hope this helps.

Robert,

the crash you had in pwconvert is listed in the solved problems of V7.3B-eco1.

So I guess you didn't upgrade to the latest ECO version but to V7.3B plain.

Am I correct?
$ pwver should list V7.3-210B for the latest ECO version.

thanks hans

this command worked great thanks

robert70 — Tue, 09 Nov 2010 10:08:23 GMT

>>$pwver should list V7.3-210B for the latest ECO version

we have V7.3-200B

Re: spaces replaced by __20 after pathworks upgrade

Hans Hosang — Tue, 09 Nov 2010 10:23:44 GMT

Your version is outdated, Robert.
I'd upgrade to V7.3B-eco1 asap.

You can download it from our web:
