How can a file grow beyond 2GB (2.8 GB) without getting crashed. Use a file type other than J4; one that uses 64 bit offsets. See the environment variables docs: JEDI_PREFILEOP parameters take precedence before command line JEDI_POSTFILEOP parameters take precedence after command line e.g. To convert all files on "jbackup" tape to J4 files set the following environment variable be using jrestore. export JEDI_PREFILEOP=TYPE=J4 (Unix) Can use quotes to surround multiple parameters You can use type JS or JR (assuming that you have the correct release of jBASE - please include such information with your posts as per posting guidelines) 2. Can a J4 type file grow more than 2GB? (as far as I know we have change the file type to JP or JR if we want to exceed 2GB limit for a single file) No, it cannot. You must pick one of the other file types. However, also in prior emails, I explain that really you should archive data and so on, to keep system response times at their best (at least until you can buy my new filesystem) :-) According to my previous experinece whenever a file reaches 2GB exactly at 2GB the sytem will throw an error message and file will not be operatable anymore. Yes - it is as per my explanation to you (or someone else with the same question) about this, and many prior answers; please see the group search: http://groups.google.com/group/jBASE/search?hl=en&group=jBASE&q=2GB&qt_g=Search+this+group Jim --~--~---------~--~----~------------~-------~--~----~ Please read the posting guidelines at: http://groups.google.com/group/jBASE/web/Posting%20Guidelines IMPORTANT: Type T24: at the start of the subject line for questions specific to Globus/T24 To post, send email to jBASE@googlegroups.com To unsubscribe, send email to jbase-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/jBASE?hl=en -~----------~----~----~----~------~----~------~--~---
