Adobe Campaign Classic - Snowflake Update using adobe guide has broken the snowflake connection

Avatar

Level 4

Using the adobe snowflake guide at Configure access to Snowflake | Adobe Campaign the snowflake instance on our adobe campaign classic dev instance (rhel) was update from snowflake-odbc-2.20.2.x86_64.rpm to snowflake-odbc-2.25.4.x86_64.rpm. 

 

The primary part of the update was performed using the following script

/usr/local/neolane/nl6/bin/fda-setup-scripts/snowflake_odbc-setup.sh

 

Initially this script would not run for the following reasons

1) The linux host is rhel but the script only references debian, centos and redhat

2) Network security prevented the script form connecting to https://sfc-repo.snowflakecomputing.com/odbc/linux/latest/index.html to determine the latest release and retrieve the rpm for the update

 

To work around the issues with the script the following changes were made

snowflake_odbc-setup.sh changes

1) Updates lines containing => if [ "$DISTRO_NAME" = "centos" ] || [ "$DISTRO_NAME" = "redhat" ]  ..... to => if [ "$DISTRO_NAME" = "centos" ] || [ "$DISTRO_NAME" = "redhat" ] || [ "$DISTRO_NAME" = "rhel" ]

2) Comment out the logic which downloads the latest from https://sfc-repo.snowflakecomputing.com/odbc/linux/latest/index.html 

Execution changes

1) Manually download snowflake-odbc-2.25.4.x86_64.rpm to folder /usr/local/neolane/nl6/bin/fda-setup-scripts

2) Run script as ./snowflake_odbc-setup.sh --snowflake 2.25.4

 

The script completed normally with the following log output


[root@xxxxxxxx /usr/local/neolane/nl6/bin/fda-setup-scripts]# ./snowflake_odbc-setup.sh --snowflake 2.25.4

Finished setup of Snowflake 2.25.4 ODBC driver.

 

 

After the update the snowflake connection was tested and it failed as follows (prior to the update the test worked)

isql -v snowflake my_username my_password

[IM002][unixODBC][Driver Manager]Data source name not found, and no default driver specified

[ISQL]ERROR: Could not SQLConnect

 

After the update script was run the following directory had been removed

/usr/lib64/snowflake/odbc (/usr/lib64/snowflake still exist but odbc and it's contents were deleted)

 

Any insights or guidance would be welcome.

After further investigation it looks like the "yum install -y snowflake-odbc-2.25.4.x86_64.rpm" step executed by

./snowflake_odbc-setup.sh --snowflake 2.25.4 removed the odbc directory in /usr/lib64/snowflake.  To fix this issue command "yum reinstall -y snowflake-odbc-2.25.4.x86_64.rpm" was run which successfully recreated the missing directory.  After a few additional minor configuration changes the snowflake connection works fine.
