PicLan host install for Mentor PRO build 184.108.40.206
December 10, 1997
This release has beta status
PicLan build 220.127.116.11 is intended to correct the following reported
problems with 18.104.22.168:
PicLan SERVER-PROCESS virtual abort
Forward Link Zero R15 at 793:0AB
This abort occurs on the receiving end of Pick to Pick copy operations
using PL-COPY. In order for the abort to be encountered there must
be a large number of items of varying sizes. The abort is also network
and system timing dependent. It typically takes a copy of several
tens of thousands of items to encounter the error.
This error appears to be a bug in the PicLan buffer management routine
and has to do with frame boundaries and re-using workspace within the PicLan
buffer. The buffer routine in abs frame PL-8 has been modified to,
hopefully, not encounter this problem.
Testing with test data copying 750,000 items has been completed without
PicLan SERVER-PROCESS log inefficiency
The PicLan SERVER-PROCESS activity log is designed to keep the last
200 entries. This is done so that the log file will not fill up with
too many entries. The log file is also flagged as a DY file so that
the system incremental save functions will not save deleted item ids.
On Mentor PRO, the DY flagging does not appear to work and the log
file will grow very large with deleted item entries for incremental saves.
PicLan has been modified to periodically CLEARFILE the log file in order
to reset the incremental save functions. This is a bug in Mentor
PRO that PicLan has had to work around.
If you are using PicLan for high-volume file transfer operations and
particularily for transferring large number of items Pick to Pick, you
should consider toggleing the SERVER-PROCESS log off to improve transfer
performance. You can toggle the log frame by typeing MONITOR-SERVER
and pressing 'L'.
As of December 10, 1997, this release has only been briefly tested at Modular
Software. Use care when loading this release onto production systems.
