[C077] Could not find symbol 'SQLAllocConnect'

Question

I try to connect Oracle to PostgreSQL with Heterogeneous Connectiviti.
I'm work on:
S.O.: Linux SUSE 9.2
PostgreSQL: 8.0
Oracle: 10g Enterprise Edition Release 10.1.0.2.0
psqlODBC:07-03
The configuration of HS is:
listener.ora
LISTENER =

(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = locahost)(PORT = 1521))

inithsodbc.ora
# This is a sample agent init file that contains the HS parameters that are

# HS init parameters
HS_FDS_CONNECT_INFO = hsodbc
HS_FDS_TRACE_LEVEL = on
HS_FDS_TRACE_FILE_NAME= /usr/local/lib/hsodbc.trc
HS_FDS_SHAREABLE_NAME = /usr/local/lib/psqlodbc.so
set ODBCSYSINI=/etc/unixODBC/odbc.ini
The configuration of ODBC is:
[ODBC Data Sources]
hsodbc = PostgreSQL ODBC Driver DSN
[hsodbcL]
Description = PostgreSQL
Driver = /usr/local/lib/psqlodbc.so
Trace = Yes

I'm create table "TEMP":
SQL>cerate table TEMP(id numeric);
SQL>table created.
and create dblink:
SQL>CREATE PUBLIC DATABASE LINK hsodbc CONNECT TO "postgres" IDENTIFIED BY "postgres" USING 'hsodbc';
SQL>Database link created.
When i execute
SQL>select * from "TEMP"@hsodbc;
select * from "TEMP"@hsodbc
ERROR at line 1:
ORA-28500: connection from ORACLE to a non-Oracle system returned this message:
[Generic Connectivity Using ODBC]DRV_InitTdp: DB_ODBC_INTERFACE (718): ; [C077]

DB_ODBC_INTERFACE (722): ; [C079] Failed to load dynamic library
'/usr/local/lib/psqlodbc.so'
ORA-02063: preceding 3 lines from HSODBC
what i can do for solve this problem?

Answer 1

Whe i'm use
HS_FDS_SHAREABLE_NAME = /usr/local/lib/psqlodbc.so
The trace log say:
[Generic Connectivity Using ODBC] version: 4.1.0.0.0050
connect string is: defTdpName=hsodbc;SYNTAX=(ORACLE8_HOA, BASED_ON=ORACLE8,
