#### _Detailed explanation of the problem:_ Hi together, When using the Adabas utility adafin, we receive the error message shown in the attachment. Here is the used command: **adafin db=${DBNR} file=\* usage=ds**. I am aware that this error can occur when adafin tries to access superdescriptors. However, as I understand it, that is not the case with this command. Where am I going wrong? Could the error have something to do with the Linux version we’re using (6.6.0.2)? ![adafin_error](https://global.discourse-cdn.com/techcommunity/original/3X/0/f/0ff45f55b8d2ff2a6e19b87c13a6a3755236c515.png) ---

Are any files locked for exclusive use? Check the DIB for utility locks - such as another utility running or failed. ---

Hi Douglas, thanks for your answer! No, nothing is locked. The files aren’t locked, and there aren’t any utility locks either. Best regards, Vincent Schoone ---

I’d suggest a support ticket. Since the utility has only done one I/O to the associator, it is identifying an issue very early on. You might run ADAVFY to validate the ASSO control blocks. ---

Could you please provide the output of the following commands? To check whether any files are locked for non-utility use: `adaopr dbid=${DBNR} display=ucb` To check whether any files are currently locked by active users: `adaopr dbid=${DBNR} display=uq_files` Could you also let us know what happens when you run ADAFIN against a specific file number? `adafin dbid=${DBNR} file=nnn usage=ds` Regarding your environment, I also noticed that the Adabas version you are using (6.6.0.2) has been out of support for several years. While I am not aware of any specific issue in this area that is related to that version, I would recommend considering an upgrade to the latest product version, or at least to a currently supported release. ---

Hi Sven, thanks for your answer! - No file is locked by Utilities (adaopr db=$DBNR di=ucb) - Yes, there are users currently using the database But the question is, why is this a problem for adafin? The documentation doesn’t say anything about exclusive access. Or to be more specific: Does adafin require exclusive access — yes or no? ---

No, adafin does not require exclusive access. However, if a utility is running that locks the file (UTI lock) or an application has an EXF lock, then adafin cannot open the file for ACCess. ---
