GEN_DATA file list directive for UNIX/Linux Performance Tuning

[Nicolai]

Hello Everyone.

Stumped upon this tech note today and wanted to share it with you. Works on Solaris and Linux only. The tool works really great and can produce huge amount of random data in very short time. You can even "restore"  the random generated data, however the restored data will be verified but else ignored.

If the NEW_STREAM directive is used as first directive status 69 is returned.

Will Work:

GEN_DATA
GEN_KBSIZE=2000000
GEN_MAXFILES=20
GEN_PERCENT_RANDOM=50

Will fail:

NEW_STREAM
GEN_DATA
GEN_KBSIZE=2000000
GEN_MAXFILES=20
GEN_PERCENT_RANDOM=50

Policy VS bpbackup:

Data generated by bpbackup can't be restored, the job go active in the GUI but never do anything. Work as intended if the data is generated by a policy.
