Disable Mac OS X Gatekeeper

Ocassionally, there is a need to install an app created by a developer that is not identified by the security policy in place on the Firm’s MacBook.

Here is the short procedure I identified it works for me:

  1. in terminal type: sudo spctl --master-disable
  2. verify with: spctl --status
  3. open the application and quit it
  4. in terminal, type: sudo spctl --master-enable
  5. verify the status: spctl --status
  6. verify that the policy is restored via: System Prefrerences … -> Security and Privacy  -> General

Strange error when renaming a table

ORA-14047: ALTER TABLE INDEX RENAME may not be combined with other operations

When we try to rename a table or index name in Oracle, we use a simple command as following

ALTER TABLE[SCHEMA_NAME].[OLD_TABLE_NAME]RENAME TO[NEW_TABLE_NAME];

If we put into schema names to this command, we can deal with ORA-14047 error.
This error raise when we put schema name in front of the last_table_name.

ORA-14047: ALTER TABLE INDEX RENAME may not be combined with other operations
ALTER TABLE SCOTT.TABLE_NAME RENAME TO SCOTT.TABLE_NAME2;
ORA-14047: ALTER TABLE INDEX RENAME may not be combined with other operations
ALTER TABLE SCOTT.TABLE_NAME RENAME TO TABLE_NAME2;
Table altered.

It is same with Index renaming.
