    Install Orafce for AlloyDB Omni

    Select a documentation version: AlloyDB Omni does not include the Orafce extension , but you can manually add it to an existing AlloyDB Omni installation by following the instructions on this page to provide additional functions and operators from the Oracle database.

    Before you begin

    Ensure that you've installed AlloyDB Omni on your system.

    Single-server

    Add Orafce to your AlloyDB Omni installation

    To add the Orafce extension to your AlloyDB Omni installation, follow these steps:

    1. Find your installed AlloyDB Omni version labels: 
      docker run --rm -it  google/alloydbomni cat VERSION.txt

      The output is similar to the following:

      AlloyDB Omni version: 15.5.4

      Take note of the AlloyDB Omni version number; you need it in the next step.

    2. Set the OMNI_VERSION environment variable: 
       OMNI_VERSION 
 = 
 VERSION

      Replace VERSION with the complete database server version from the previous step—for example, 15.5.4 .

    3. Create a new AlloyDB Omni container that includes Orafce:

      Docker

        
 mkdir  
~/alloydb-omni-orafce 
  
 tee  
-a  
~/alloydb-omni-orafce/Dockerfile  
 << EOF 
 ARG OMNI_VERSION 
 FROM postgres:15-bookworm AS postgres 
 RUN apt-get update && \ 
 apt-get install -y --no-install-recommends \ 
 postgresql-15-orafce && \ 
 apt-get purge -y --auto-remove && \ 
 rm -rf /var/lib/apt/lists/*

  cd 
  
~/alloydb-omni-orafce 
  
 sudo  
docker  
build  
--build-arg  
 OMNI_VERSION 
 = 
 $OMNI_VERSION 
  
--tag  
google/alloydbomni-with-orafce: $OMNI_VERSION 
  
.

      Podman

 EOF 
 
  
  cd 
  
~/alloydb-omni-orafce 
  
 sudo  
podman  
build  
--build-arg  
 OMNI_VERSION 
 = 
 $OMNI_VERSION 
  
--tag  
google/alloydbomni-with-orafce: $OMNI_VERSION 
  
.

      Docker

        
 mkdir  
~/alloydb-omni-orafce 
  
 tee  
-a  
~/alloydb-omni-orafce/Dockerfile  
 << EOF 
 ARG OMNI_VERSION

  cd

 sudo  
docker  
build  
--build-arg  
 OMNI_VERSION 
 = 
 $OMNI_VERSION 
  
--tag  
google/alloydbomni-with-orafce: $OMNI_VERSION 
  
.

      Podman

        
 mkdir  
~/alloydb-omni-orafce 
  
 tee  
-a  
~/alloydb-omni-orafce/Dockerfile  
 << EOF 
 ARG OMNI_VERSION 
 FROM postgres:15-bookworm AS postgres 
 RUN apt-get update && \ 
 apt-get install -y --no-install-recommends \ 
 postgresql-15-orafce && \ 
 apt-get purge -y --auto-remove && \ 
 rm -rf /var/lib/apt/lists/* 
 FROM google/alloydbomni:${OMNI_VERSION} 
 COPY --from=postgres /usr/lib/postgresql/15/lib/orafce.so /usr/lib/postgresql/15/lib/orafce.so

 COPY --from=postgres /lib/aarch64-linux-gnu/ /lib/aarch64-linux-gnu/ 
 EOF 
 
  
  cd 
  
~/alloydb-omni-orafce 
  
 sudo  
podman  
build  
--build-arg  
 OMNI_VERSION 
 = 
 $OMNI_VERSION 
  
--tag  
google/alloydbomni-with-orafce: $OMNI_VERSION 
  
.
    4. Create a new container with AlloyDB Omni named my-omni-orafce :

      Docker

      docker run --name my-omni-orafce  -e POSTGRES_PASSWORD= NEW_PASSWORD 
-d google/alloydbomni-with-orafce: OMNI_VERSION

      Podman

      podman run --name my-omni-orafce  -e POSTGRES_PASSWORD= NEW_PASSWORD 
-d google/alloydbomni-with-orafce: OMNI_VERSION
    5. Connect to your database with the Orafce extension:

      Docker

      docker exec -it my-omni-orafce psql -h localhost -U postgres

      Podman

      podman exec -it my-omni-orafce psql -h localhost -U postgres
    6. Enable Orafce: 
       CREATE 
  
 EXTENSION 
  
 IF 
  
 NOT 
  
 EXISTS 
  
 ORAFCE 
 ;
    7. Confirm that Orafce is installed and enabled: 
       SELECT 
  
 oracle 
 . 
 sysdate 
 ();
      The output looks similar to the following: 
       postgres 
 =# 
  
 SELECT 
  
 oracle 
 . 
 sysdate 
 (); 
  
 sysdate
