where the value of the KEY symbol may be
different than EXTPROC, but must be the same as
the value of the KEY symbol in the tnsnames.ora
file. The same is true for the value of the
SID_NAME symbol, but that it is always
PLSExtProc.
If this text file is changed, then the listener service
must be restarted. Oracle 8 and 9 do not seem to
use the ORACLE_HOME entry. Instead, Oracle
uses the ORACLE_HOME entry in the Windows
registry, and the ORACLE_HOME environment
variable on UNIX systems. So, when the listener is
started, then the ORACLE_HOME must point to
the directory, where the Oracle server is installed.
That usually reads, like
/mount-directory/app/oracle/product/version
If in doubt:
1. Execute the statements in the same
environment, where the listener is started:
ORACLE_HOME = /mountdirectory/app/oracle/product/ver
sion
export ORACLE_HOME
2. Start the listener with the command
$ORACLE_HOME/bin/lsnrctl
3. Check status, and stop/start it according to its
status.
tsnames.ora
The tnsnames.ora file must have lines as follows:
EXTPROC_CONNECTION_DATA.CAMSOFT.
COM =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY =
EXTPROC))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)
The value of KEY must be the same as the value of
KEY in the listener.ora file, and the value of SID
must be the same as the value of SID_NAME in the
listener.ora file.
ORA-06520 PL/SQL: Error
loading external library
If the communication with the extproc agent is
operable the user still can be faced with the above
error message.
This happens if the extproc agent can not load the
CsCartridge.dll or the CsCartridge.so into memory.
The reason is either:
• the CsCartridge library does not exist OR
• some libraries it depends on do not exist.
Dependencies
The CsCartridge library depends on every platform
on the existence of
• OCI library. (extension may be .dll, .so, .sl)
For a list of additional dependencies for specific
operating systems, please see “” on page 263.
