Programming / Re: PXPlus crashing after error 61

Mike - Thanks for that info. I wasn't aware of these version issues since I don't handle the installs, so I appreciate your detailed explanation!

We did just update them a few minutes ago to the latest 12.5 build, but that didn't help, so we'll try installing v17 and see if that resolves the issue.

James, like you, I've only seen an error 61 in relation to Windx installations.  This process is running as a cron process on the Linux server, so Windx isn't involved.  I suspect the error 61 relates to some permission denied at the OS level.

Jason, thanks for the suggestion on checking the 'IZ'. I did run the process and dump the PRM to a trace file, just to confirm that the 'IZ' parameter is enabled when run as a cron.  It is enabled, so the process shouldn't be encountering memory limits.

Loren

You could be facing a OS compatibility issue. There never was a version 12.50 for any version of Redhat 7.  The latest Redhat release for version 12.50 was Redhat 6.

You can see all the versions of PxPlus 12.50 at https://home.pvxplus.com/downloads/pxp1250/

If you want to run Redhat 7.9 you likely will need to use a newer PxPlus built for/on that release -- Version 14 PxPlus 2017 -- although even that release would have been made for an earlier version of Redhat 7. 

Redhat 7.9 was only released in 2020, PxPlus 12.50 was released in 2015.

Loren,
If you suspect a problem with memory limits, you also need to consider the limit that an individual session can use.
Check prm('SZ') and prm('IZ').

If prm('IZ') is off, I would turn it on and see if the problem goes away.
If it does, then you can decide if you want to leave it on or if you instead prefer to increase the prm('SZ') to allow each session more memory, but not unlimited.
If it doesn't, back to square one.

The only time we run into the Error 61 problem is when the user hasn't set up the WindX authorization properly. Why it's happening on a LOCAL statement or with a particular server file (I presume) is a curiosity indeed.

Programming / PXPlus crashing after error 61
« Last post by Loren Doornek on February 15, 2024, 02:32:50 PM »
We have a strange PXPlus crash occurring at one client, using a routine that is used at multiple clients. 

The routine gets an error 61 (Authorization failure) when issuing a LOCAL command to localize several variables.  At that point, the SETERR branch is taken, and the routine tries to close files.  The PXPlus session then crashes when closing one particular file (the same file every time). 

I don't really have a clue what would cause an error 61 on a LOCAL command!

- I've removed the LOCAL command that was getting an error.  The error then occurs on a different line that is also issuing a LOCAL command, and the session still crashes.
- I've renamed the particular file that is being closed every time the session crashes (thus leaving it in place on the hard drive), then re-created the file.  Still crashes.

Before the system crashes, I print the MSG(-1) to a trace file, but it is blank. 

We suspect a memory/swap file issue, so I also dump the contents of the Linux "free" command to text file immediately after the error 61.  The file shows that there is over 2megs of free memory at that moment, so it wouldn't seem to be an issue with allocating memory for the LOCAL command.  I don't know if the swap file is configured correctly, but it does show swap file available but not being used (or only a tiny amount of swap used).

The client is running PXPlus version 12.50 on a Linux server running RedHat 7.9. 

Any suggestions on how to resolve this, or other ideas on what to check?

Nomads / Re: Tool to update providex.ddf file to new version

When you run Data Dictionary Maintenance, there is an automatic check of the version of the providex.ddf and providex.dde files, and if they are out of date they are automatically updated to the current version you are running.

Thanks Mike! That was the issue.
I added logic to calculate the total standard column widths in pixels and scale them down by percentage when the total exceeded 32767.
