Kris, The submitter is ABC, the directory owner is XYZ. The submitter has WRITE/NEWRITE authority to the directory and files. Nora Graves nora.e.gra...@irs.gov Main IRS, Room 6531 (202) 622-6735 Fax (202) 622-3123 SE:W:CAR:MP:D:KS:BRSI

You say "This user is the owner of most of the directories" You mean: the submitter is userid ABC, the dirids are all named "fpoolid:ABC.something"? 2011/4/14 Graves Nora E <nora.e.gra...@irs.gov> We are having an intermittent problem with SFS and I'm hoping someone may have some ideas of what to pursue next. We have several batch jobs that run under VMBATCH overnight. Sometimes they are not able to create a file in a directory, even though most times it is successful. The only differences in the executions are the file names; for many of these the File Type is the date. In the job I am most familiar with, these are the specifics. The job runs Monday-Saturday. This year, it has failed on January 4, January 12, February 9, March 18, March 25, and April 13. It has run successfully the other days. Other than the QUERY statements below, it has not changed. The job runs in a work machine, WORK7. The job is submitted by the User ID of the database owner. The SFS directories are owned by a 3rd user. Failures occur in many of the subdirectories, not just one subdirectory owned by this user. This user is the owner of most of the directories containing the data files we create in batch, so I don't think it's significant that it's the ID that has the problem. However, as far as I know, it is the only ID that does have the problem. This job uses VMLINK to acquire a write link to SFS directory. This always looks to be successful--no error is given. (Other jobs use GETFMADDR and ACCESS to acquire the write link to the directory. This always appears successful as well). Once the file is ready to be copied from the Work Machine's 191 disk to the SFS directory, the intermittent error appears. The vast majority of the time, the write is successful. However, sometimes, the job gets this error message: DMSOPN1258E You are not authorized to write to file XXXXXX 20110413 Z1 The file is not large--last night's file was only 12 blocks. At the suggestion of our systems programmer, I've put in a lot of query statements. I've issued QUERY LIMITS for the job submitter; it's only used 84% of the allocation, with several thousand blocks available. The SFS directory owner has only used 76% of its allocation, with several thousand more blocks still available. The filepool is not full. I've issued QUERY FILEPOOL CONFLICT. There is no conflict. I've issued QUERY ACCESSED. The directory shows that is accessed R/W. When the write is unsuccessful, the program then loops through 5 tries of releasing the access, reacquiring the access, and attempting to write the file again. This has never been successful. I've issued both a COPYFILE and a PIPE to try to write the file; these do not work once there has been a failure. We've looked at the operator consoles to see if we can find any jobs running at the same time. We haven't found any that are accessing that directory structure. There aren't any dumps to look at--it looks perfectly successful other than the fact that it won't write the file. Does anyone have any suggestions of something to try next?
