In https://access.redhat.com/documentation/en-us/red_hat_3scale_api_management/2.4/html/infrastructure/building_a_3scale_api_management_system_image_with_the_oracle_database_relational_database_management_system#building_the_system_image
In the step 5 the command showed
{{for dc in system-app system-resque system-sidekiq system-sphinx; do oc env dc/$dc --overwrite DATABASE_URL="oracle-enhanced://

{USER}:{PASSWORD}@{ORACLE_DB_URL}:{PORT}/{DATABASE}"; done}}

is incorrect because system-resque is not in the 2.4 architecture so that should be changed in
{{for dc in system-app system-sidekiq system-sphinx; do oc env dc/$dc --overwrite DATABASE_URL="oracle-enhanced://{USER}

:

{PASSWORD}

@

{ORACLE_DB_URL}

:

{PORT}

/

{DATABASE}

"; done}}
