Dropping public synonyms in a pluggable database

Question

I have an Oracle 12c container database with several pluggable databases in it.  In one of the pluggable databases, I de-installed OLAP by running the following scripts:
SQL> @%oracle_home%/olap/admin/catnoamd.sql
SQL> @%oracle_home%/olap/admin/olapidrp.plb
SQL> @%oracle_home%/olap/admin/catnoxoq.sql
SQL> @%oracle_home%/olap/admin/catnoaps.sql
After running the scripts, I then generated the SQL statements to remove invalid OLAP synonyms, by executing the following:
select 'drop public synonym ' || object_name || ';'
from dba_objects
where status <> 'VALID'
and owner = 'PUBLIC'
and object_type = 'SYNONYM'
and object_name like '%OLAP%';
When I execute the resulting SQL statements in the pluggable database, I get the following error for all of them:
ERROR at line 1:
ORA-65040: operation not allowed from within a pluggable database
If I switch back to the CDB$ROOT container and execute the same statements, I get the following error:
ERROR at line 1:
ORA-01432: public synonym to be dropped does not exist
How can I remove these invalid public synonyms from my pluggable database?

OK - let's go back to the basics
For 12c you should NOT be manually removing/uninstalling/disabling Oracle options.
There is a CHOPT utitlity specifically designed to enable or disable certain options.
http://docs.oracle.com/cd/E11882_01/install.112/e48740/post_inst_task.htm#CHDFEIJF
5.2.7 Enabling and Disabling Database Options
When you install Oracle Database, some options are enabled and others are disabled. To enable or disable a particular database feature for an Oracle home, shut down the database and use the chopt tool. See Example 5-1.
The chopt tool is a command-line utility that is located in the ORACLE_HOME/bin directory. The syntax for chopt is:
That doc section shows that one of the 'db_option' values available is 'olap' to disable. NOTE: the uttility DISABLES the option. It is still not clear to me why you would attempt to actually deinstall it.
If your concern is licensing then all you need to do is disable it. It is very possible that you have corrupted that PDB by attempting a manual uninstall. Only Oracle support could tell you for sure.
If it is a new PDB and licensing is your issue you may be far better off starting over and using CHOPT to disable the options you don't want.
1. why are you 'unistalling' olap in the pdb? What PROBLEM are you trying to solve?
2. why are you manually dropping synonyms?
3. how did you decide to execute those particular scripts? Is there an Oracle doc you are following that has instructions for deinstalling olap? Does that doc give you the order to execute the scripts in?
If you review the catnoamd.sql script you will see that just about ALL that it does is drop public synonyms.
Most of those synonyms that it drops have 'olap' in the name.
Which suggests that if Oracle wanted those synonyms YOU are trying to drop to be dropped you have to wonder why it didn't drop them itself in that script.
Was that script the FIRST script you executed?
1. Modify your 'drop' script to simply create the DDL to drop the synonyms.
2. Then examine the data dictionary to see what objects those synonyms refer to.
3. Then check if those objects still exist or not
4. Also check those scripts to see if they did anything (e.g. drop) those objects.
Post the results of the above.
