ArcCatalog error: Failed to connect the specified server. Server library could not be loaded

When trying to make a direct connect to ArcSDE on 64 bit Solaris, the following error occurred:
Failed to connect ot database. Server library could not be loaded.

There is an ESRI document on this:

Error:  Failed to connect the specified server. Server library could not be loaded

Article ID:36510
Software: ArcGIS - ArcEditor 9.2, 9.3, 9.3.1 ArcGIS - ArcInfo 9.2, 9.3, 9.3.1 ArcGIS - ArcView 9.2, 9.3, 9.3.1 ArcSDE 9.2, 9.3, 9.3.1
Platforms:N/A

Error Message

When using direct connect with ArcSDE on a 64-bit operating system, the following error message is encountered:

"Failed to connect the specified server. Server library could not be loaded."

Cause

Because ArcGIS Desktop is a 32-bit operating system application, it cannot work with applications created with 64-bit operating system libraries.

Solution or Workaround

Uninstall the Oracle Net Client 64-bit version and install the Oracle Net Client 32-bit version on the 64-bit operating system. Also, ensure the Oracle Net Client's full version matches the Oracle database's full version (for example, 10.2.0.4).

Still it is very hard to work around the error!

Drop duplicate objects in SYS and SYSTEM schema before upgrading to Oracle 11gR2

When doing checking before manually upgrading a database from 10.2.0.3 to 11.2.0.1 (Oracle Note: Complete Checklist for Manual Upgrades to 11gR2 [ID 837570.1]), the following SQL script returns one duplicate objects in SYS and SYSTEM schema:


column object_name format a30

select object_name, object_type
from dba_objects
where object_name||object_type in
   (select object_name||object_type 
    from dba_objects
    where owner = 'SYS')
and owner = 'SYSTEM';
       
OBJECT_NAME                    OBJECT_TYPE
------------------------------ --------------------
AQ$_SCHEDULES                  TABLE  --- ok
AQ$_SCHEDULES_PRIMARY          INDEX --- ok

DBMS_REPCAT_AUTH               PACKAGE --- ok

DBMS_REPCAT_AUTH               PACKAGE BODY   --- ok

DBMS_SHARED_POOL               PACKAGE --- not ok!

According to  Oracle Note 1030426.6 (HOW TO CLEAN UP DUPLICATE OBJECTS OWNED BY SYS AND SYSTEM ):
  • Generate script to drop the unwanted object

select 'DROP ' || object_type || ' SYSTEM.' || object_name || ';' 
from dba_objects 
where object_name||object_type in 
   (select object_name||object_type  
    from dba_objects 
    where owner = 'SYS') 
and owner = 'SYSTEM'; 

DROP PACKAGE SYSTEM.DBMS_SHARED_POOL;

  • Drop it:
SQL> show user
USER is "SYS"
SQL> DROP PACKAGE SYSTEM.DBMS_SHARED_POOL;

Package dropped.
