I came across a rather annoying little bug yesterday…
One of the guys was trying to compile an Oracle Form on the app server and got this message.
*** ASSERT at file pdw1.c, line 4061 PSDGON missing. Can't get object number Source Location = XNSPC0P99_2013_06_12_17_44_38__AB[71, 7]
Uncle Google pointed me in the direction of this MOS Note [ID 1276725.1].
It turns out it is a problem with the 126.96.36.199 client, which happens to be the version that ships with Forms and Reports Services. The Forms compilation fails when the form references a database function that uses the Function Result Cache in 11g.
I didn’t fancy applying the patch last night, so I just commented out the RESULT CACHE clause in the packaged function, compiled the form, then put the RESULT CACHE clause back in. Job’s a good’un!
This morning I’ve followed the MOS note and applied the patch in out Dev environment and it seems to have fixed the issue.
Just so I don’t forget about this, I’ve also added a mention of it in my ever-growing Oracle Forms and Reports Services 11gR2 Configuration Notes article.
