Archives: Creating database software images in OCI using Terraform
I’ll continue exploring using OCI services with Terraform. Now it is time to start looking into databases. High Oracle PM-s have been lobbying for a database image creation service, where you just supply patch numbers and Oracle will return you the fully built database home. I see that this service is now available in the cloud (for cloud databases only).
I’ll try it out, using terraform.
resource "oci_database_database_software_image" "db_23051" {
# NB! Waits until image is provisioned
# This took 10m47s to provision
compartment_id = oci_identity_compartment.compartment.id
display_name = "23-db-23051"
image_shape_family = "VM_BM_SHAPE" # For use in Database Base service
# oci db version list
# NB! 23.0.0.0 seems to be behind on patches, 23.0.0.0.0 seems to be current
database_version = "23.0.0.0.0"
image_type = "DATABASE_IMAGE"
# Can't find how to query that list - but the format seems quite self-explanatory
# Exadata Cloud Service Software Versions (Doc ID 2333222.1)
patch_set = "23.5.0.24.07"
}
I had hard time finding out the allowed values for parameter patch_set, but they seem to be described in Doc ID 2333222.1 (and what the contents are).
Examining the state of the created resource
ilmar_kerm@codeeditor:oci-terraform-example (eu-stockholm-1)$ terraform state show oci_database_database_software_image.db_23051
# oci_database_database_software_image.db_23051:
resource "oci_database_database_software_image" "db_23051" {
compartment_id = "ocid1.compartment.oc1..aaaaaaaasbzzr7i54kpv6oc5s7i23isiij6n2tyentd5udc34ptzagovrgqa"
database_software_image_included_patches = [
"35221462",
"36741532",
"36744688",
]
database_software_image_one_off_patches = [
"35221462",
"36741532",
"36744688",
]
database_version = "23.0.0.0.0"
defined_tags = {
"Oracle-Tags.CreatedBy" = "default/ilmar.kerm@gmail.com"
"Oracle-Tags.CreatedOn" = "2024-09-29T12:36:02.119Z"
}
display_name = "23-db-23051"
freeform_tags = {}
id = "ocid1.databasesoftwareimage.oc1.eu-stockholm-1.anqxeljr4ebxpbqadhgioquzxv6qtrui72e3sn3c7iwxcljncmdq7fx5jdbq"
image_shape_family = "VM_BM_SHAPE"
image_type = "DATABASE_IMAGE"
is_upgrade_supported = false
patch_set = "23.5.0.24.07"
state = "AVAILABLE"
time_created = "2024-09-29 12:36:02.123 +0000 UTC"
}
One thing I notice here (verified with testing), that the parameter database_software_image_one_off_patches gets pre-populated with included patches after the image is created – so you have to include the included patches also the the parameter value.
With 19c version process is similar
resource "oci_database_database_software_image" "db_19241" {
# NB! Waits until image is provisioned
# This took 16m4s to provision
compartment_id = oci_identity_compartment.compartment.id
display_name = "19-db-19241"
image_shape_family = "VM_BM_SHAPE" # For use in Database Base service
# oci db version list
database_version = "19.0.0.0"
image_type = "DATABASE_IMAGE"
patch_set = "19.24.0.0"
}
I did try to apply MRP on top of it, but maybe the cloud patch numbers are different, since the usual MRP patch number did not apply on top of it.
In the next post I’ll try to spin up an actual database using the image.
