APAR Error Description / Circumvention

-----------------------------------------------
A DataLink File Manager (DLFM) prefix was registered using the
Add Prefix to DLFM (ADDPFXDLFM) command. Later, the Remove
Mounted FS (RMVMFS or UNMOUNT) command was used specifying
TYPE(*UDFS) and the DLFM prefix in the MNTOVRDIR parameter.
After this, DLFM operations using that prefix did not operate
correctly. Some file system objects could be renamed or removed
from the prefix directory whether or not they were associated
with database file records. An IPL of the system corrected this
behavior.

CORRECTION FOR APAR SE54642 :
-----------------------------
The unmount function incorrectly disrupted the connection
between the integrated file system objects and the DataLink File
Manager. The PTF prevents the problem from occurring. Any
objects that were renamed or removed while the connection was
disrupted must be renamed back to their original names or
restored to the system in order to establish the connection
again.

CIRCUMVENTION FOR APAR SE54642 :
--------------------------------
None.


Activation Instructions


None.




Special Instructions


********************************************************************
THE FOLLOWING ARE SUPERSEDED SPECIAL INSTRUCTIONS. IF THE SUPERSEDED
PTF HAS ALREADY BEEN APPLIED AND ITS SPECIAL INSTRUCTION FOLLOWED,
IT IS NOT NECESSARY TO FOLLOW THAT SPECIAL INSTRUCTION AGAIN.
********************************************************************

SPECIAL INSTRUCTIONS FOR SUPERSEDED PTF SI37545 :
=================================================

The /dev/urandom special file is a non-blocking source of random
data similar to this same special file found on other platforms.
In the IBM i implementation, reads from /dev/urandom will use the
Generate Pseudorandom Numbers (Qc3GenPrns) API as the source of
random data.  Writes to /dev/urandom will use the Add Seed for
Pseudorandom Number Generator (Qc3AddPRNGSeed) API to seed the
random numbers returned by /dev/urandom as well as Qc3GenPrns.

Reading from /dev/urandom does not require any special authority.
Writing to /dev/urandom requires *ALLOBJ special authority.

Additional information regarding /dev/urandom can be found in the
AIX Information Center here:
