Funky problem with SQL ALIAS

[G Armour <garmour400m@xxxxxxxxx>]

Funky problem with SQL ALIAS.  Have been creating and dropping an ALIAS
without problems in a java application for awhile now.  All of a sudden,
the alias can be neither created ("already exists") nor dropped ("not
found").  I tried the following in interactive SQL:

> create alias srtfiles/su300acd for srtfiles/su300(su300)
  SU300ACD in SRTFILES type *FILE already exists.
> drop   alias smsfiles/su300acd
  SU300ACD in SRTFILES type *FILE not found.

I also tried doing this with a different alias name (everything else the
same) and had no problems.

This is V5R2, with TL03161 permanently applied.  PTF group SF99502 (the
DB2 group) shows the level at 7.  PTF group SF99519 (the HIPER group) is
at level 62.  These are the only two PTF groups installed.

I searched the APARs, and came up empty handed, I think.  The only one
that remotely comes close is SE12060, which is closed.  No reference to a
PTF, though.  Would the fixing PTF be referenced in the APAR if there was
one?

Finally, in case anyone needs more details about the Java app, below my
sig is the log that shows how the CREATE/DROP was working, then all of a
sudden, not working.  What is not shown is that there is a process between
the CREATE & DROP.  I do not know Java, and I am speculating at this point
that this is not a Java problem but a DB2 problem.

TIA, GA
