linux查看oracle密码

❶ linux怎么查看oracle版本

[oracle@ceglnx01 bin]$ sqlplus -v
SQL*Plus: Release 10.2.0.4.0 - Proction

1:使用file命令查看32位还是64位客户端。

Oracle Client 32 bit
[oracle@db-server-01 ~]$ which sqlplus
/u01/app/oracle/proct/10.2.0/db_1/bin/sqlplus
[oracle@db-server-01 ~]$ file /u01/app/oracle/proct/10.2.0/db_1/bin/sqlplus
/u01/app/oracle/proct/10.2.0/db_1/bin/sqlplus: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.2.5, dynamically linked (uses shared libs), not stripped

Oracle Client 64 bit

[oracle@db-server-02 ~]$ which sqlplus
/u01/app/oracle/proct/10.2.0/db_1/bin/sqlplus
[oracle@db-server-02 ~]$ file /u01/app/oracle/proct/10.2.0/db_1/bin/sqlplus
/u01/app/oracle/proct/10.2.0/db_1/bin/sqlplus: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, not stripped
或者
Oracle Client 32 bit

[oracle@db-server-01 logs]$ cd /u01/app/oracle/proct/10.2.0/db_1/bin
[oracle@db-server-01 bin]$ file oracle
oracle: setuid setgid ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.2.5, dynamically linked (uses shared libs), not stripped
Oracle Client 64 bit
[oracle@db-server-02 ~]$ cd /u01/app/oracle/proct/10.2.0/db_1/bin
[oracle@db-server-02 bin]$ file oracle
oracle: setuid setgid ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, not stripped

2： 通过查看$ORACLE_HOME下的lib或lib32目录，如果两个目录都存成，则为64位，如果只有lib目录.则为32位客户端。
[oracle@db-server-01 db_1]$ ls -d lib
lib
[oracle@db-server-01 db_1]$ ls -d lib*
lib lib32

❷ Linux下如何启动、关闭Oracle以及打开关闭监听

1、以oracle用户登录系统，如果是root用户，使用su - oracle切换用户。

❸ linux 下的oracle怎么启动

1、首先打开命令行窗口，切换到su - oracle，启动数据库监听。
