OSS Standard Posix Threads
DSAP/DCOM
The H06.06 version of DSAP/DCOM (T9543H01^ABH) is large OSS file safe, but pre-
H06.06 versions are not. If you fall back from H06.06 to an earlier RVU, HP
recommends that you install T9543H01^ABH after the fallback.
Backup and Restore 2
If you are falling back to H06.05, install the Backup and Restore 2 SPR
T0744H01^AAA to restore files smaller than 2 GB. Files larger than 2 GB are skipped.
T0744H01^AAA does not support pre-H06.05 RVUs.
OSS Standard Posix Threads
The OSS Standard Posix Threads product (T1248) is enhanced to:
•
Catch externally generated OSS signals in addition to the synchronous signals that
result from events occurring inside the process.
•
Deliver caught signals to the correct thread.
As a part of this enhancement, new APIs are available:
•
spt_alarm()
•
spt_signal()
Migration
To enable the signal-handling enhancement, you must set the environment variable
SPT_THREAD_AWARE_SIGNAL to value 1 within the shell (export
SPT_THREAD_AWARE_SIGNAL=1).
