Hello All,

I'm working on upgrading our E-Business suite database from 9.2.0.8 to
10.1.0.5 on HP-UX 11.11.  I was trying to convert to native plsql
compilation and ran into a problem with extending LOB segments in SYSTEM.
More specifically: ORA-1691: unable to extend lobsegment
SYS.SYS_LOB0001772641C00003$$ by 311072 in tablespace SYSTEM.

Things went from bad to worse with: ORA-00600: internal error code,
arguments: [17069], [0xC0000005B06FFDA0], [], [], [], [], [], []  This
ora600 is known to Metalink as "Failed to pin library cache object after 50
attempts."  Distressing.

My question involves the logsegment error.  I tried adding a 2GB data file
which had no effect.  I then turned on autoextend on one of the datafiles
and Hey Presto!  the lobsegment errors went away although not the ORA-0600
errors.  Has anyone seen this before?  Is it a bug or a feature?

BTW, because of time constraints I went back to interpreted mode and got on
with the upgrade.

Allan
