Server는 Oracle DB가 있는 구성에서 설치를 할 수 있습니다.
1.
설치 전에 필요 패키지가 있는데 없으면 설치해줍니다.
$ rpm -qa perl-Env
perl-Env-1.04-460.el9.noarch
없는경우 root에서 dnf 명령어로 수행합니다.
# dnf -y install perl-Env

3.
설정을 위해서는 pyqcfg.sql 라는 sql스크립트를 수행하여 설정을 해야합니다.
스크립트의 위치는 /opt/oracle/product/23ai/dbhomeFree/oml4py/server입니다.
cd $ORACLE_HOME/oml4py/server 로도 이동이 가능합니다.
$ pwd
/opt/oracle/product/23ai/dbhomeFree/oml4py/server
$ ls

omlprelod.sql pyqcfg_dwcs.sql pyqembed.plb pyqrollback.sql
5.
CDB$ROOT에 설정을 먼저 진행합니다.
PYQSYS계정을 생성하고 해당 계정의 tablespace (SYSAUX)와 TEMP tablespace(TEMP)를 설정합니다.
spool 로 생성한 install_root.txt로 로그를 확인할 수 있습니다.

OML4Y를 이용하기 위한 새로운 유저를 생성
pyquser.sql 를 이용하여 편하게 유저를 생성할 수 있습니다.
사용 방법을 아래와 같습니다.
@pyquser.sql oml_user USERS TEMP unlimited pyqadmin
앞에서부터 각 변수의 설명입니다.
Username ,User's permanent tablespace , User's temporary tablespace , Permanent tablespace quota , PYQADMIN role
PDB에서 생성할 예정이므로 PDB로 접속후 수행합니다.
SQL> show pdbs

2 PDB$SEED READ ONLY NO
3 FREEPDB1 READ WRITE NO
SQL> alter session set container=FREEPDB1;
세션이 변경되었습니다.
SQL>
SQL> @pyquser.sql oml_user USERS TEMP unlimited pyqadmin
세션이 변경되었습니다.
password의 값을 입력하십시오: oracle
구 1: create user &&1 identified by &password
신 1: create user oml_user identified by oracle
구 2: default tablespace &&2
신 2: default tablespace USERS
구 3: temporary tablespace &&3
신 3: temporary tablespace TEMP
구 4: quota &&4 on &&2
신 4: quota unlimited on USERS
사용자가 생성되었습니다.
구 4: 'create procedure, create mining model to &&1';
신 4: 'create procedure, create mining model to oml_user';
구 6: IF lower('&&5') = 'pyqadmin' THEN
신 6: IF lower('pyqadmin') = 'pyqadmin' THEN
구 7: execute immediate 'grant PYQADMIN to &&1';
신 7: execute immediate 'grant PYQADMIN to oml_user';
PL/SQL 처리가 정상적으로 완료되었습니다.
세션이 변경되었습니다.
9.접속 테스트
python에 접속하여 위에서 생성한 유저(oml_user)로 connect하여 python의 함수를 수행하는 테스트입니다. 2가 나오면 정상입니다.
$ python3
Python 3.12.3 (main, Jul 3 2024, 08:35:38) [GCC 8.5.0 20210514 (Red Hat 8.5.0-18.0.6)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import oml
>>> oml.connect(user='oml_user', password='oracle', host='192.168.56.1', port=1521, service_name='FREEPDB1')
>>> oml.script.create("TEST", func='def func():return 1+1', overwrite=True)
>>> res = oml.do_eval(func='TEST')
>>> res
2
테스트 후에는 삭제
oml.script.drop("TEST")
완료.
