[comp.sys.ibm.pc.rt] PTF 1751 for AIX

jw@pan.UUCP (Jamie Watson) (09/15/89)

I have just received PTF 1751 for AIX/RT from IBM Support.  The following
is a list of the contents and patch levels of this PTF.  The "X" indicates
that this is a higher patch level than PTF 1749.

NOTE: The IBM Support person told me that there is a known problem with
      this PTF of systems using Distributed Services.  In addition, we
      discovered that NFS does not work after this PTF is installed.
      If you use either of these, you *must* not install this PTF.

Hello,

 PTF 1751 definately has a bug that causes problems for all remote file
systems.  This includes AFS.  (one of the remote filesystems we run at
CMU)

Though this bug exists in the operating system update one can update
other selected parts of the system using the updatep command.  If you
recieved 1751 to correct some problem other than the BASE SYSTEM 
PROGRAM you should be able to update just that component.  If a
particular component thinks it needs the version of the BASE SYSTEM
PROGRAM on 1751 it should check the version of the installed OS (called
opsys in /usr/lpp) using the prereque facilities and not install itself
without the new version of the OS.

Regards,

Paul

Speaking of 1700-level updates that *cause* problems, has anyone installed
one of the 1700's and then found that programs that do a select() on
the the maximum # of file descriptors (200 from getdtablesize) that the
kernel starts *opening* file descriptors up to the maximum configured
and then goes nuts with "File table overflow" ??  I've seen this twice
now but have not been able to narrow down the 1700-level fix that 
introduces this bug (Base AIX 2.2.1 works fine in this regard). If 
anyone knows more about this please let me know...Thanks.
