Confirming encrypted tables

Using the command below, it is possible to view the tables within the DAMO-MYISAM or DAMO_INNODB storage engine:

mysql > select TABLE_SCHEMA, TABLE_NAME, ENGINE from INFORMATION_SCHEMA.TABLES where ENGINE='DAMO_MYISAM' or ENGINE='DAMO_INNODB';

Changing the storage engine

Change storage engine of each observed table to MyISAM or InnoDB:

mysql > alter table . engine=['MyISAM'|'InnoDB'];

Plug-in Deletion

#fancy-title-673ee5b795482 a{ color: #274e75; }

Deleting storage engines and functions installed in MySQL.

Execute $DAMO_INST_HOME/sql/unins-plugin.sql script to delete storage engines and functions installed in MySQL:

$> mysql –u root –p < $DAMO_INST_HOME/sql/unins_plugin.sql

Pausing the Key manager

Installed file deletion

#fancy-title-673ee5b797323 a{ color: #274e75; }

Deleting symbolic link and install directory:

$> unlink $CIS_CC_HMAC_PATH/libcis_cc-3.2.so  
$> unlink $CIS_CC_HMAC_PATH/libcis_ce-3.2.so  
$> unlink $CIS_CC_HMAC_PATH/libcis_cc-3.2.so.hmac  
$> unlink $CIS_CC_HMAC_PATH/libdamo.so  
$> rm –rf $DAMO_INST_HOME
