Hi @all,
hope someone can help me. I got stuck on a problem with a SMF field. Have
someone ever tried to analyze a SMF74 ST 4 (Coupling Facility Activity) record.
I do not see the value 5425 as a long floating point value in the record in any
field. Can someone point me into the right direction?
HELP…
Thx
Uwe

SMF Field:

D H
52 34 R744STRC 8 l_float The total number of IXLLIST, IXLCACHE, or IXLLOCK
requests made. This field will not necessarily equal the sum
or R744SSRC, R744SARC, and R744SSTA due to internal
processing. Use of the batch unlock function can produce
large discrepancies because R744STRC is incremented for
each lock being released, but only one coupling facility
operation is executed.
