Server process won't start properly without BYPASS priv

Art Wiens — Sun, 15 Oct 2006 11:30:54 GMT

I am trying to setup an environment for Attunity to access a particular datasource. The server process seems to start but fails without the expected results. I am trying to use SET WATCH/CLASS=MAJOR FILE to troubleshoot with and without BYPASS on the process. Without BYPASS, I see this in the logfile:

File (2383,1,0) is SYS$SYSDEVICE:[SYS0]SYS$I18N.DIR;1 and file (37,1,0) is SYS$SYSDEVICE:[VMS$COMMON]SYS$I18N.DIR;1

All files referenced (others weren't listed as they seem to succeed) have at least (W:RE) available to it.

What is (0,0,0) and what is status 910? There doesn't seem to be a file with id 0,0,0 .

Any ideas?

So after further investigation, that's a "red herring", a working process does it too. I found the cause ... the process wasn't able to create a logfile. I didn't think a process needed W:W permission on a parent directory if the subdirectory it was trying to write into had W:RWE permission.

This fails:

$ dir/sec [000000]navroot.dir
Directory SYS$SYSDEVICE:[000000]

NAVROOT.DIR;1 [SYSTEM](RWE,RWED,RE,RE)
Total of 1 file.

$ dir/sec [navroot]tmp.dir
Directory SYS$SYSDEVICE:[NAVROOT]

TMP.DIR;1 [SYSTEM] (RWE,RWE,RE,RWE)
Total of 1 file.

This works:

$ dir/sec [000000]navroot.dir
Directory SYS$SYSDEVICE:[000000]

NAVROOT.DIR;1 [SYSTEM](RWE,RWED,RE,RWE)
Total of 1 file.

$ dir/sec [navroot]tmp.dir
Directory SYS$SYSDEVICE:[NAVROOT]

TMP.DIR;1 [SYSTEM] (RWE,RWE,RE,RWE)
Total of 1 file.

Isn't the W:E on the parent enough to be able to make use of the subdirectory's W:W?

Cheers,
Art

Art,

Try leaving BYPASS granted, then use auditing to determine what the process is doing with it.

$ SET AUDIT/AUDIT-
/ENABLE=(ACCESS=BYPASS,PRIVILEGE=SUCCESS:BYPASS)

Once this is set, start your process, then examine the audit journal for entries resulting from activity by that process.

Art,

as you see by the following examples, you did not nead writ access to the parent directory.

Directory CNC_SCRATCH:[ROHW.ROHWEDDER]

TMP.DIR;1 [BO,ROHWEDDER] (RWE,RWE,RE,RE)

Directory CNC_SCRATCH:

1.DIR;1 [BO,ROHWEDDER] (REW,RWE,RE,RWE)

Directory CNC_SCRATCH:

A.A;2 [DECNET,FAL$SRV] (RWED,RWED,RE,)
