Dear all, I'm using the jstat utility to check the attributes of hashed files and for some of them i can see data in primary space but for others in both, primary and secondary
My question is how to find whether a file needs resize or not based on jstat output (for both cases) and if it needs how to calculate the new modulo As an example you can consider the following files: jsh ~ -->jstat -v F.LOCKING File ../bnk.data/eb/F.LOCKING Type=J4 , Hash method = 5 Created at Wed Jan 6 19:45:35 2010 Groups = 1629 , Frame size = 8192 bytes , Secondary Record Size = 16384 bytes Restore re-size parameters : (none) File size = 16457728 bytes , Inode = 1248028 , Device = Id 9223372212948434946 Last Accessed Tue Mar 2 08:40:18 2010 , Last Modified Tue Mar 2 08:40:18 2010 Backup = YES , Log = YES , Rollback = YES , Network = AUTO Record Count = 24207 , Record Bytes = 10265930 Bytes/Record = 424 , Bytes/Group = 6301 Primary file space: Total Frames = 1950 , Total Bytes = 9840241 Secondary file space: Total Frames = 56 , Total Bytes = 425689 jsh ~ -->jstat -v FBNK.EB.CONTRACT.BALANCES File ../bnk.data/re/FBNK_EB_CONTRACT_BALANCES Type=J4 , Hash method = 5 Created at Wed Feb 24 10:56:56 2010 Groups = 250001 , Frame size = 4096 bytes , Secondary Record Size = 8192 bytes Restore re-size parameters : (none) File size = 1061769216 bytes , Inode = 1230014 , Device = Id 9223372212948434946 Last Accessed Wed Feb 24 14:34:34 2010 , Last Modified Wed Feb 24 14:34:34 2010 Backup = YES , Log = YES , Rollback = YES , Network = AUTO Record Count = 1346947 , Record Bytes = 387310863 Bytes/Record = 287 , Bytes/Group = 1549 Primary file space: Total Frames = 259220 , Total Bytes = 387310863 Secondary file space: Total Frames = 0 , Total Bytes = 0 System Information ================== OS AIX 5.3.9.0 jbase: Major 5.0 , Minor 20 , Patch 0364 (Change 85159) Regards, Xze -- 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 [email protected] To unsubscribe, send email to [email protected] For more options, visit this group at http://groups.google.com/group/jBASE?hl=en
