[ADSM-L] API (tdpo) for linux problem !

hi all, i'm trying to configure TDPO on linux redhat, but i'm getting this --->

[root@CLA-0(MAG_NPS) /opt/tivoli/tsm/client/oracle/bin64]
# tdpoconf showenv -tdpo_opt=tdpo.opt


IBM Tivoli Storage Manager for Databases:
Data Protection for Oracle
Version 5, Release 4, Level 1.0
(C) Copyright IBM Corporation 1997, 2007. All rights reserved.

ANU0156E Could not load the Tivoli Storage Manager API.
[root@CLA-0(MAG_NPS) /opt/tivoli/tsm/client/oracle/bin64]
#

i installed API 5.4.1.0  (32 version), then API 5.4.1.0 (64 version
since it says that 32 is dependency ?!?), then i installed BA Client
5.4.1.0,
and then 5.4.1.0-TIV-TSMORA-LinuxX64.bin (this versions are because it
complements the server version)

the content of tdpo.opt is this (nothing special) --->

DSMI_ORC_CONFIG    /opt/tivoli/tsm/client/api/bin64/MMSDB_tdpo.opt
*DSMI_ORC_CONFIG    /opt/tivoli/tsm/client/api/bin/MMSDB_tdpo.opt

*DSMI_LOG           <dirname>

*TDPO_FS            orc9_db

*TDPO_NODE          <hostname>
TDPO_NODE          MMSDB_tdpo

*TDPO_OWNER         <username>
*TDPO_OWNER         oracle

*TDPO_PSWDPATH      /usr/tivoli/tsm/client/oracle/bin64
TDPO_PSWDPATH      /home/oracle

TDPO_DATE_FMT      4
*TDPO_NUM_FMT       1
*TDPO_TIME_FMT      1

*TDPO_MGMT_CLASS_2   orcbackup
*TDPO_MGMT_CLASS_3   mgmtclass3
*TDPO_MGMT_CLASS_4   mgmtclass4

the content of  /opt/tivoli/tsm/client/api/bin/MMSDB_tdpo.opt (and
/opt/tivoli/tsm/client/api/bin64/MMSDB_tdpo.opt) is --->

servername mmsdb_tdpo

which redirects to mmsdb_tdpo stanza in dsm.sys file

the normal BA client works okay with no problems, i also tried with 32
version of tdpo but i get the same errors ....

error explanation --->

ANU0156E
Could not load the Tivoli Storage Manager API.
Explanation:

The Tivoli Storage Manager API could not be loaded.
System action:

Processing ends.
User response:

Ensure the Tivoli Storage Manager API is correctly installed. Run the
Data Protection for Oracle application client with the /TRACEFLAGS=API
/TRACEFILE=filename options and view the tracefile to determine why it
could not be loaded. Another possible cause is that the TSMAPI.DLL
does not exist in the system directory. Re-install the Tivoli Storage
Manager API, if this is the case.

What am i doing wrong ? Any clues would be greatly appreciated. Thanks
in advance.
