一.配置 Systemd file（开机可以自动oracle，也可以查看启动状态）
a.定义环境变量
[oracle@ol7 ~]$ cat /etc/sysconfig/DB11G.oracledb
ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=/u01/app/oracle/product/11.2.0.4/db_1
ORACLE_SID=DB11G
[oracle@ol7 ~]$ cat /usr/lib/systemd/system/DB11G@
DB11G@lsnrctl.service DB11G@oracledb.service
b.配置监听服务
[oracle@ol7 ~]$ cat /usr/lib/systemd/system/DB11G@lsnrctl.service
# this is an example, modify for free
[Unit]
Description=oracle net listener
After=network.target
[Service]
Type=forking
EnvironmentFile=/etc/sysconfig/DB11G.oracledb
ExecStart=/u01/app/oracle/product/11.2.0.4/db_1/bin/lsnrctl start
ExecStop=/u01/app/oracle/product/11.2.0.4/db_1/bin/lsnrctl stop
User=oracle
[Install]
WantedBy=multi-user.target
c.定义数据库服务
[oracle@ol7 ~]$ cat /usr/lib/systemd/system/DB11G@oracledb.service
# this is an example, modify for free
[Unit]
Description=oracle net listener
After=network.target lsnrctl.service
[Service]
Type=forking
EnvironmentFile=/etc/sysconfig/DB11G.oracledb
ExecStart=/u01/app/oracle/product/11.2.0.4/db_1/bin/dbstart /u01/app/oracle/product/11.2.0.4/db_1
ExecStop=/u01/app/oracle/product/11.2.0.4/db_1/bin/dbshut /u01/app/oracle/product/11.2.0.4/db_1
User=oracle
[Install]
WantedBy=multi-user.target
[oracle@ol7 ~]$ systemctl daemon-reload
[oracle@ol7 ~]$ systemctl enable DB11G@lsnrctl.service DB11G@oracledb.service
这里要提前规划好相应的分区，规划好了管理才方便
mkdir -p /oracledata/nc/nctables
mkdir -p /oracledata/nc/ncindex
chown -R oracle:oinstall /oracledata/nc/nctables
chown -R oracle:oinstall /oracledata/nc/ncindex/
chmod -R 755 /oracledata/*
mkdir -p /oracletemp/DB11G/dump
chown -R oracle:oinstall /oracletemp/DB11G/dump
chmod -R 755 /oracletemp/DB11G/dump
二.数据库文件
控制文件:
两个互为镜像，分配在不同的磁盘上
SQL> select name from v$controlfile;
NAME
--------------------------------------------------------------------------------
/u01/app/oracle/oradata/DB11G/control01.ctl
/oraclearch/flash_recovery_area/DB11G/control02.ctl
redo日志：一共四个组，每组两个成员，前期的大小是预估的，后期正常的时候，计算redo大小，再调整。
SQL> select group#, member from v$logfile;
GROUP# MEMBER
---------- --------------------------------------------------------------------------------
3 /u01/app/oracle/oradata/DB11G/redo03.log
1 /u01/app/oracle/oradata/DB11G/redo01.log
2 /u01/app/oracle/oradata/DB11G/redo02.log
1 /oracle/redo1/redo01a.log
2 /oracle/redo1/redo02a.log
3 /oracle/redo1/redo03a.log
4 /u01/app/oracle/oradata/DB11G/redo04.log
4 /oracle/redo1/redo04a.log
8 rows selected
SQL> select * from v$log;
GROUP# THREAD# SEQUENCE# BYTES BLOCKSIZE MEMBERS ARCHIVED STATUS FIRST_CHANGE# FIRST_TIME NEXT_CHANGE# NEXT_TIME
---------- ---------- ---------- ---------- ---------- ---------- -------- ---------------- ------------- ----------- ------------ -----------
1 1 361 524288000 512 2 NO CURRENT 22234232 2017/4/24 2 281474976710

4 1 358 524288000 512 2 YES INACTIVE 22127329 2017/4/23 2 22205745 2017/4/24 1
SQL>
归档日志 archivelog：
SQL> archive log list
Database log mode Archive Mode
Automatic archival Enabled
Archive destination /oracletemp/DB11G/archive_log
Oldest online log sequence 358
Next log sequence to archive 361
Current log sequence 361
SQL>
因为是正式的数据库。所以归档位置有两处，一处失败了，备份到另外一处，没有做镜像，因为没多的服务器
log_archive_dest_1 string location=/oraclearch/archive_l
og
log_archive_dest_10 string
log_archive_dest_11 string
log_archive_dest_12 string
log_archive_dest_13 string
log_archive_dest_14 string
log_archive_dest_15 string
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
log_archive_dest_16 string
log_archive_dest_17 string
log_archive_dest_18 string
log_archive_dest_19 string
log_archive_dest_2 string location=/oracletemp/DB11G/arc
hive_log
管理 undo：
查看用的那个undo表空间：
SQL> select tablespace_name,status,contents from dba_tablespaces;
TABLESPACE_NAME STATUS CONTENTS
------------------------------ --------- ---------
SYSTEM ONLINE PERMANENT
SYSAUX ONLINE PERMANENT
UNDOTBS1 ONLINE UNDO
TEMP ONLINE TEMPORARY
USERS ONLINE PERMANENT
NNC_DATA01 ONLINE PERMANENT
NNC_INDEX01 ONLINE PERMANENT
7 rows selected
SQL> show parameter undo
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
undo_management string AUTO
undo_retention integer 900
undo_tablespace string UNDOTBS1
SQL>
undo_retention 内，不可以覆盖（非强制）
SQL> select tablespace_name,status,contents,retention from
2 dba_tablespaces;
TABLESPACE_NAME STATUS CONTENTS RETENTION
------------------------------ --------- --------- -----------
SYSTEM ONLINE PERMANENT NOT APPLY
SYSAUX ONLINE PERMANENT NOT APPLY
UNDOTBS1 ONLINE UNDO NOGUARANTEE
TEMP ONLINE TEMPORARY NOT APPLY
USERS ONLINE PERMANENT NOT APPLY
NNC_DATA01 ONLINE PERMANENT NOT APPLY
NNC_INDEX01 ONLINE PERMANENT NOT APPLY
7 rows selected
自动增长减少ora_015555：过段时间数据库平稳了，再固定空间大小
SQL> select file_name,autoextensible,increment_by from dba_data_files ;
FILE_NAME AUTOEXTENSIBLE INCREMENT_BY
-------------------------------------------------------------------------------- -------------- ------------
/oracledata/DB11G/users01.dbf YES 160
/u01/app/oracle/oradata/DB11G/undotbs01.dbf YES 640
/u01/app/oracle/oradata/DB11G/sysaux01.dbf YES 1280
/u01/app/oracle/oradata/DB11G/system01.dbf YES 1280
/oracledata/nc/nctables/nnc_data01.dbf YES 6400
/oracledata/nc/ncindex/nnc_index01.dbf YES 6400
6 rows selected
项目的基本配置:
create user ***** identified by *****;
CREATE TABLESPACE NNC_DATA01 DATAFILE '/u01/tablespace/nnc_data01.db' SIZE 500M AUTOEXTEND ON NEXT 50M EXTENT MANAGEMENT LOCAL UNIFORM SIZE 256K ;
CREATE TABLESPACE NNC_INDEX01 DATAFILE '/u01/tablespace/nnc_index01.dbf' SIZE 500M AUTOEXTEND ON NEXT 50M EXTENT MANAGEMENT LOCAL UNIFORM SIZE 128K ;
select group#,sequence#,status,bytes/1024/1024 from v$log;
select group#,status,type,member from v$logfile;
alter user ***** default tablespace NNC_DATA01 TEMPORARY TABLESPACE temp;
GRANT connect,dba to zyctdw;
CREATE USER ***** IDENTIFIED BY ***** DEFAULT TABLESPACE NNC_DATA01 TEMPORARY TABLESPACE temp;
GRANT connect,dba to *****;
我以前是负责公司linux运维的，这次是第一次部署公司的数据库，所以有些地方可能不妥。
