Change {page} to the page number. It's indexed at 1, so -f 1 would be the first page.

SBN PrelimFinal FTP process broken

From: Ruckman, Maurice (HAL)
Sent: Sunday, January 01, 2012 7:24 PM
To: HAL Service Request Center (HAL); Doan, Thomas (HAL Contractor)
Cc: De Vera, Marlon (HAL); Harris, Tyrone (HAL); Hofsetz, Therron (HAL); Augustine, Anila (HAL)
Subject: SBN PrelimFinal FTP process broken, Need UNIX help to resolve
Importance: High

SRC,

Please call out to the Unix, it will be necessary to have them delete some files to allow a schedule task to start again on the half hour. Please see attached email for previous example that happened on 12/16/2011 where Marlon opened a ticket to resolve. Please copy all recipients of this email with the work order.

Unix Team,
Please do the following, NOT on the half-hour, because a crontab is setup to run the scripts on the half-hour, such as 7:30pm, 8:30pm etc., just don’t want you in the middle of cleanup when the next job starts, and feel free to call me if there are any questions 206.650.7576:

Step #1:
Check if any bash jobs are running in HALPRDWAS02, named : 'LoadPrelimFinalDocs.sh' or 'LPFD*'. If so end task(s).

Step #2:
Delete all of the files in the following folder on halprdwas02
/prod/sbndocs/transfer/final/*
There are currently 68 files with a date/time stamp 12/31/2011 9:30am to 12/31/2011 9:32am

Step #3:
Delete the following lock file on halprdwas02
/prod/scripts/LoadPrelimFinalDocs.lock

Thomas,

Would you complete the necessary “emergency” documentation on Tuesday?

All,

The FTP Job failed on 12/31/2011 @ 10:30AM and its lock file was left in place, subsequently there are PDF files date stamped 12/31/2011 @ 9:30AM+ which were not processed. Have verified that all files in RRD archive folder are both on the production PDF server and exists in the Oracle database. Symptom emails “untitled” has been sent on the hour since that time with the message body of “LoadPrelimFinalDocs.sh IS STILL RUNNING! EXITING NOW!” when two of those happen back-to-back, it normally means there’s a problem.

Thanks,

Maurice Ruckman
