Change Oracle Database User Password ¿À¶óŬ µ¥ÀÌÅͺ£À̽º »ç¿ëÀÚ ºñ¹Ð ¹øÈ£ º¯°æ

To ensure security of the Oracle database system and prevent unauthorized access to the Oracle database, it¡¯s important for Oracle users to not only using strong and long Oracle passwords to avoid brute force or dictionary attacks, but also to change the Oracle user password regularly. ¿À¶óŬ µ¥ÀÌÅͺ£À̽º ½Ã½ºÅÛÀÇ º¸¾ÈÀ» À¯ÁöÇÏ·Á¸é Oracle µ¥ÀÌÅͺ£À̽º¿¡ ¹«´ÜÀ¸·Î ¾×¼¼½ºÇÏÁö ¸øÇϵµ·Ï, ¿À¶óŬ »ç¿ëÀÚ¸¦À§ÇÑ °­·ÂÇÏ°í ±ä ¹«·ÂÀ̳ª »çÀü °ø°ÝÀ» ÇÇÇϱâ À§ÇØ ¿À¶óŬÀÇ ºñ¹Ð ¹øÈ£¸¦ »ç¿ëÇÏÁö ¾Ê´Â,ÇÏÁö¸¸ ¿ª½Ã Á¤±âÀûÀ¸·Î ¿À¶óŬÀº »ç¿ëÀÚ°¡ ºñ¹Ð ¹øÈ£¸¦ º¯°æÇÏ´Â °ÍÀÌ Áß¿äÇÕ´Ï´Ù . Oracle users also have to change the password when the password has or going to expire, if database system administrator implements and enforces strict password control with PASSWORD_LIFE_TIME option for user profiles which limits the number of days the password can be used for authentication to login to the system. ¶ÇÇÑ ¿À¶óŬÀº »ç¿ëÀÚÀÇ ¾ÏÈ£¸¦ º¯°æÇØ¾ß ÇÒ ¶§ ºñ¹Ð ¹øÈ£°¡ ¶Ç´Â ¸¸·á·Î°¡´Â ±¸ÇöÇÏ´Â °æ¿ì ½Ã½ºÅÛ °ü¸®ÀÚ ¹× »ç¿ëÀÚ ÇÁ·ÎÆÄÀÏÀ»À§ÇÑ µ¥ÀÌÅͺ£À̽ºÀÇ ¾ÏÈ£ ÀÎÁõÀ»À§ÇÑ ÀÏ¿¡ ·Î±×ÀÎÇÏ´Â µ¥ »ç¿ëÇÒ ¼öÀÖ´Â ¼ö¸¦ Á¦ÇÑÇÏ´Â ¾ö°ÝÇÑ ºñ¹Ð ¹øÈ£¸¦ Á¦¾î PASSWORD_LIFE_TIME ¿É¼Ç °­¿ä ½Ã½ºÅÛ.

To change the Oracle password, users can use SQL*Plus or Oracle SQL and PL/SQL language interface administration tool such as Toad for Oracle. ¿À¶óŬÀÇ ºñ¹Ð ¹øÈ£¸¦ º¯°æÇÏ·Á¸é, »ç¿ëÀÚ´Â SQL * Plus ³ª ¿À¶óŬ SQL¿Í PL / Oracle ¿ë µÎ²¨ºñ °°Àº SQL ¾ð¾î ÀÎÅÍÆäÀ̽º °ü¸® µµ±¸¸¦ »ç¿ëÇÒ ¼öÀÖ½À´Ï´Ù. No matter what SQL apps you use, the commands and SQL query languages used to change the password are similar. ´Â SQL ´ç½ÅÀÌ ¸í·É°ú SQL Äõ¸® ¾ð¾î¸¦ »ç¿ëÇÏ¿© ¾ÏÈ£¸¦ º¯°æÇÏ´Â µ¥ »ç¿ëµÇ´Â ¾î¶² ¾ÖÇà ¸®ÄÉÀ̼ǿ¡ »ó°ü¾øÀÌ ºñ½ÁÇÕ´Ï´Ù.

There are two SQL command syntaxes that can be used to change Oracle database user password: ÀÌ¹Ì ¿À¶óŬ µ¥ÀÌÅͺ£À̽º »ç¿ëÀÚ ºñ¹Ð ¹øÈ£¸¦ º¯°æÇÏ´Â µ¥ »ç¿ëµÉ ¼öÀÖ´Â µÎ SQL ¸í·É ±¸¹® À§Ä¡ :

or (from Oracle8 and above): ¶Ç´Â Oracle8°ú À§ÀÇ ()¿¡¼­ :

PASSWORD ºñ¹Ð ¹øÈ£

For above SQL query, if you need to change another user¡¯s password, use the following command: SQL Äõ¸®¸¦ À§ÇØ À§ÀÇ °æ¿ì, ´Ù¸¥ »ç¿ëÀÚÀÇ ¾ÏÈ£¸¦ º¯°æÇÏ·Á¸é ´ÙÀ½ ¸í·ÉÀ» »ç¿ëÇØ¾ßÇÕ´Ï´Ù :

For PASSWORD command, after you press Enter, you will be prompted to input the old password and new password interactively. ºñ¹Ð ¹øÈ£ ¸í·É µé¾î, ÈÄ Å°¸¦ ÀÔ·ÂÇÏ°í »õ ºñ¹Ð ¹øÈ£¸¦ ´ëÈ­ÇüÀ¸·Î µÈ ¾ÏÈ£¸¦ ÀÔ·ÂÇ϶ó´Â ¸Þ½ÃÁö°¡ Ç¥½ÃµË´Ï´Ù. For example: ¿¹¸¦ µé¸é :

Retype new password: »õ ºñ¹Ð ¹øÈ£¸¦ ´Ù½Ã ÀÔ·Â :

Note: You need to have enough privileges to change other Oracle user¡¯s password. Âü°í : ´Ù¸¥ ¿À¶óŬ »ç¿ëÀÚÀÇ ¾ÏÈ£¸¦ º¯°æÇÏ·Á¸é ÃæºÐÇÑ ±ÇÇÑÀÌ ÀÖ¾î¾ßÇÕ´Ï´Ù.

As the variable in italic implied by name, user_name is the user whose password wishes to be changed, and new_password is the new password to assign. ¿¡¼­ º¯¼ö À̸§¿¡ ÀÇÇØ ¹¬½ÃÀûÀ¸·Î ±â¿ïÀÓ²Ã, user_nameÀº ´©±¸ÀÇ ºñ¹Ð ¹øÈ£¸¦ ¼Ò¿ø »ç¿ëÀÚ°¡ º¯°æÇÒ ¼öÀÖ´Ù, ±×¸®°í new_password ÇÒ´ç¿¡ »õ ¾ÏÈ£ÀÔ´Ï´Ù.

As ALTER USER SQL syntax will send the new password to the Oracle database server unencrypted if use without Advanced Security Option, and thus expose to security risk, Oracle users should always use the PASSWORD command to change the Oracle user password. °í±Þ º¸¾È ¿É¼Ç¾øÀÌ »ç¿ëÇÏ´Â °æ¿ì, º¸¾È À§Çè¿¡ ³ëÃâµÇ¹Ç·Î »ç¿ëÀÚ°¡ SQL ±¸¹®À¸·Î ALTER ¿À¶óŬ µ¥ÀÌÅͺ£À̽º ¼­¹ö¿¡ ¾Ïȣȭ¿¡ »õ ºñ¹Ð ¹øÈ£¸¦ º¸³»µå¸³´Ï´Ù, ¿À¶óŬÀº »ç¿ëÀÚ°¡ Ç×»ó ¿À¶óŬÀº »ç¿ëÀÚ°¡ ºñ¹Ð ¹øÈ£¸¦ º¯°æÇÏ´Â ºñ¹Ð ¹øÈ£¸¦ ¸í·ÉÀ» »ç¿ëÇØ¾ßÇÕ´Ï´Ù.
