Add Oracle Instant Client
This article explains how to upload Oracle Instant Client to BucketFS.
Exasol supports using Oracle Instant Client to connect to an Oracle database using the IMPORT FROM ORA
syntax. For more information, see IMPORT.
By default, the database is configured to use the following path for the Oracle Instant Client:
/buckets/bfsdefault/default/drivers/oracle/
Prerequisites
-
The Amazon EC2 security group must contain an inbound rule to allow traffic on the port used for the
default
bucket in BucketFS. The default port for this bucket is 2581. For more information see Authorize inbound traffic to your linux instances. -
Oracle Instant Client 23.5.0.24.07 must be downloaded to your local machine. You can download the client using this link.
Oracle Instant Client 23.5.0.24.07 is the only version supported in Exasol 8. This version has been deprecated and the download link on this page is therefore not guaranteed to work.
Change the write password of the default bucket. For more information, see Change Bucket Password.
Procedure
The following examples use curl on a Linux terminal. You can also use other interfaces and languages to execute the curl commands.
Placeholder values in the examples are styled as Bash variables, for example: $NODE_IP
. Replace these placeholders with your own values.
Upload the zip file to the specified bucket path. For more information, see Manage Buckets and Files in BucketFS.
You must use the IP address of one of the database nodes, not the address of the database access node.
For example:
curl -v --insecure -X PUT -T instantclient-basic-linux.x64-12.1.0.2.0.zip https://w:$WRITE_PW@$DATABASE_NODE_IP:2581/default/drivers/oracle/instantclient-basic-linux.x64-12.1.0.2.0.zip
The option --insecure
or -k
tells curl to bypass the TLS certificate check. This option allows you to connect to a HTTPS server that does not have a valid certificate. Only use this option if certificate verification is not possible and you trust the server.
Verification
To verify that the Oracle Instant Client is installed, perform an IMPORT statement using the IMPORT FROM ORA
syntax. For example:
CREATE OR REPLACE CONNECTION OCI_ORACLE
TO '192.168.99.103:1521/xe'
USER 'system'
IDENTIFIED BY 'oracle';
