linux环境处理Oracle 19c一些问题记录

Posted 2023-02-23 zf04295

linux环境重启Oracle 19c数据库

1.切换到Oracle环境：su - oracle
2.查看监听状态：lsnrctl status
3.lsnrctl stop
4.以DBA权限登录
sqlplus /nolog
conn /as sysdba
5.SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
6.lsnrctl status
lsnrctl start
sqlplus /nolog
conn /as sysdba
startup
7.服务器重启时，pdb默认是不启动的，先将监听启动，然后需要在超级管理下执行alter pluggable database ORCLPDB1 open; 启动pdb
说明：
ORA-01012:not logged on的解决办法
这种情况一般是shutdown数据库后有多余的进程
ps aux查看linux下所有进程，找到Oracle相关进程，依次执行 kill -9 PID 杀进程，然后在Oracle环境下再次执行startup;即可启动

在PDB模式下创建表空间

切换到PDB
alter session set container=ORCLPDB1;
创建表空间
create tablespace XXXX datafile
‘/opt/oracle/oradata/xxx.dbf’ size 10M autoextend on next 100M maxsize 34359721984 ;
增加表空间文件
alter tablespace XXXX add datafile
‘/opt/oracle/oradata/xxx.dbf’ size 10M autoextend on next 100M maxsize 34359721984 ;

在PDB模式下新建用户

说明：用户名在sql语句中一定要大写，否则创建后无法登录，大写的用户名在实际登录时可以小写。
alter session set container=ORCLPDB1;
CREATE USER “XXXX” IDENTIFIED BY “xxxx” DEFAULT TABLESPACE “XXXX” TEMPORARY TABLESPACE “TEMP”;

GRANT “PDB_DBA” TO “XXXX” WITH ADMIN OPTION;

ALTER USER “XXXX” DEFAULT ROLE “PDB_DBA”;

ALTER USER “XXXX” QUOTA UNLIMITED ON “SJGC”;

GRANT CREATE PUBLIC DATABASE LINK, CREATE ANY PROCEDURE, CREATE TABLE, CREATE ANY TABLE, SELECT ANY TABLE, CREATE ANY VIEW TO “XXXX” WITH ADMIN OPTION;

GRANT ALTER USER TO “XXXX”
权限赋予：
grant create job to XXXX;
grant manage scheduler to XXXX;
grant create any table to XXXX;
grant create any view to XXXX;
grant create any procedure to XXXX;
grant connect,resource to XXXX;
grant unlimited tablespace to XXXX;
grant create tablespace to XXXX;
grant connect to XXXX;
grant resource to XXXX;
grant alter system to XXXX;
grant create any table to XXXX;
grant create any view to XXXX;
grant create database link to XXXX;
grant create external job to XXXX;
grant create job to XXXX;
grant create table to XXXX;
grant create view to XXXX;
grant debug any procedure to XXXX;
grant debug connect session to XXXX;
grant unlimited tablespace to XXXX;
grant create any sequence to XXXX;

修改数据库时间格式

1. vi .bash_profile
2. 按i进入编辑模式
   PATH=$PATH:$HOME/bin
   export PATH
   export ORACLE_HOME=/usr/lib/oracle/19.8/client64
   export TNS_ADMIN=/usr/lib/oracle/19.8/client64
   export TNS=/usr/lib/oracle/19.8/client64
   export NLS_LANG=AMERICAN_AMERICA.AL32UTF8
   export LD_LIBRARY_PATH=$ORACL{E}_{H}OME/lib:$LD_LIBRARY_PATH
   PATH=$PATH:$HOME/bin:$ORACL{E}_{H}OME/bin:$ORACLE_HOME/lib
   export NLS_DATE_FORMAT=‘YYYY-MM-DD HH24:MI:SS’
3. source .bash_profile

定义DBMS_JOB

declare
job number;
BEGIN
DBMS_JOB.SUBMIT(
JOB => job,
WHAT => ‘INSCL;’,
NEXT_DATE => to_date(‘2021-06-09 01:00:00’,‘yyyy-MM-dd hh24:mi:ss’),
INTERVAL => ‘TRUNC(sysdate+1)+1/24’
);
commit;
end;

JOBS调度作业

JOBS调度作业不好使
查看job进程数show parameter job_queue_processes;
先将job_queue_processes=0：
alter system set job_queue_processes=0;
然后再执行，请根据实际情况定义数值，不宜过大：
alter system set job_queue_processes=50;

查看JOB情况

用户名大写
select t.job_name,
t.job_type,
t.JOB_ACTION,
t.job_class,
t.schedule_type,
t.enabled,
t.state
from dba_scheduler_job_roles t
where t.owner = ‘XXXX’
order by t.enabled;

JOB不好使的问题记录

ps -ef | grep cjq

正常情况下可以查看到下图的状态，如果只有第二行的grep说明JOB没启动

解决办法就是将数据库重启，重启后就好使了
