There's a problem with your TSM Config files.  Check for recent changes, and refer to your backups to pull earlier versions.

Other / Re: The famous but illusive 33 petabyte system
« on: November 03, 2022, 10:26:04 AM »
The largest one I'm aware of is/was in the low-single-digit petabyte range.  I would suspect that the number might have been 3.3 Petabytes...  33 sounds unfathomably large, even for CMOD.

Report Indexing / Re: Possible Issue with PPD's
« on: October 14, 2022, 09:29:21 AM »
Yeah, if the PPD format is bad, CMOD can't be expected to parse it properly.

Send it back to the team that created it and ask them to fix it.

Announcements & News / Re: SECURITY: ZLib vulnerability in CMOD
« on: October 05, 2022, 10:20:07 AM »
Just a brief update.  I've exchanged eMails with IBM, and in order to exploit this bug, an attacker would need access to modify data in the cache or secondary storage (Tivoli Storage Manager / Spectrum Protect / Cloud Storage Buckets / Filesystems).  This is a pretty extreme level of access, meaning that any attacker looking to exploit this bug would already be able to do far more damage than simply crash CMOD instances.

In short, the level of risk associated with this alert is extremely low.

Here's a little more documentation on CMOD Return Codes for arsload:

Since your second question is off topic, I'll keep my answer short:  No.  :)

If you want to have a bigger discussion around expiration, post a new topic.

Uh, is it possible to NOT set it?  How did you create the AG/App definition?  XML?

Announcements & News / SECURITY: ZLib vulnerability in CMOD
« on: September 28, 2022, 01:37:19 PM »
IBM released a security bulletin for an old vulnerability from 2018 that affects current versions of CMOD:

https://www.ibm.com/support/pages/node/6824729

In short, it would allow an attacker that ALREADY has a very high level of access to your system to cause CMOD to crash.

Upgrading to the latest fixpack is always a good idea, this is just another reason to stay current on patches.

Ask your questions below, and I'll ask the developers to pop by and respond.  Thanks.

It's safe to assume that IBM wouldn't purposely ship the same bug in newer fixpacks.

MP Server / Re: PROTOCOL values in ARS.INI
« on: September 24, 2022, 09:52:48 AM »
From the docs:

https://www.ibm.com/docs/en/cmofm/9.5.0?topic=siiaf-verifying-default-instance

Quote
The PROTOCOL parameter identifies the communications protocol used by the instance. The number 2 identifies TCP/IP, and is the only valid value.

Hi Helle...

I have some tools that can help you do exactly this.  Send me a DM here or send me an eMail.

ARS1197E Invalid generic index file format sequence

I mean, it looks like the generic index file is bad - given that the file is on the E: drive, and the resource is on the C: drive... maybe file permissions / access issues?

Sounds like you'd need a security exit for that.  But the security exits only allow you to approve or deny a login, so I don't think you could use it to kill the old session while allowing the new session to proceed.  Looks like this might be a good candidate for an enhancement request.

And for general knowledge, here's a wiki article with a bunch of command-line customizations for the client software:

Space is always a concern - if not now, in the not-too-distant future.  :)
