It is a package referenced by a session is changed between executions of the
package by the session the error message you received is normal and expected.
In prior versions of Oracle we used to see 'package state has changed' as the
error but on AIX since 9.2 we get the 'unable to load' which we used to get
only when enough contiguous free space in the shared pool did not exist.

The instructions for the CPU don't require you to run catbundle before the
database is opened. I just installed this last week, and intalling it again
tomorrow morning on another database. I have been running catbdundle psu apply
per instructions right after the instance is back OPEN again.
Also, the package body in question doesn't need a recompile after the
catbundle, it is just affecting users who have already accessed the package
before the driutl.plb script is called to replace the package body. I know this
because we ran a custom recompile script during the installation, which starts
by storing in a table all invalid objects before the deployment, followed by
only recompiling objects that are invalid after and NOT in the list from
before. On my database, this package was not INVALID.

Did you check and revalidate all your objects prior to opening the database

$ORACLE_HOME/rdbms/admin/urlrp?

FYI,
On two Oracle 10.2.0.4.0 RAC databases, after we applied Oct-2009 CPU patch,
both times some users got errors similar to the following:
ORA-29877: failed in the execution of the ODCIINDEXUPDATE routine
ORA-20000: Oracle Text error:
DRG-50857: oracle error in textindexmethods.ODCIIndexUpdate
ORA-06502: PL/SQL: numeric or value error: character to number conversion error
ORA-06512: at "CTXSYS.DRIXMD", line 438
ORA-04061: existing state of package body "CTXSYS.DRIUTL" has been invalidated
ORA-04065: not executed, altered or dropped package body "CTXSYS.DRIUTL"
ORA-06508: PL/SQL: could not find program unit being called: "CTXSYS.DRIUTL"
ORA-06
SQL Statement:
...
This is because at the end of the patch, $ORACLE_HOME/rdbms/admin/catbundle.sql
is run. On RAC, we apply the patch on local node, one node at a time. Before
the patch, VIP is relocated to another node and the services on this node are
stopped. So apps are running on other nodes. On the last node only, we run
catbundle.sql. This script creates catbundle_CPU_<DBNAME>_APPLY.sql, where
there is
@?/ctx/admin/driutl.plb
which replaces ctxsys.driutl package body. If a session on *any* node of the
RAC updates a table using a text index after driutl package body is replaced
with new code, the session will get the above error. (If it's a delete, the
routine on the first line will be ODCIINDEXDELETE). This means that the rolling
nature of the patch has a risk on production.
Eddie Awad summarizes three ways to avoid ORA-4068:
http://awads.net/wp/2007/04/04/here-is-how-to-unpersist-your-persistent-plsql-package-data/
But all need application code change. Since CPU patch is done only once per
three months, to us, it's not worth it.
The package driutl is not changed much. I'm considering commenting out the line
in catbundle_CPU_<DBNAME>_APPLY.sql and manually run it. (Also need to comment
out the last line "@&sf" in catbundle.sql.)
If you need to reproduce the error:
create table testctx as select rownum id, object_name name from user_objects;
create index indctx_testctx on testctx (name) indextype is ctxsys.context;
In another session (invalidate instead of replacing the package, because we
don't have slightly modified code which is needed in 10g and up):
exec dbms_utility.invalidate(<object_id of ctxsys.driurl package>)
Back to the first session, run any of the following:
select * from testctx where contains(name, '<some name in testctx>') > 0;
delete from testctx where id = 1; update testctx set name = 'xx' where id = 1;
