Track the Time Spent on each operation in Expdp and Impdp

Trace the Expdp and Impdp Performance Issue using LOGTIME and METRICS Parameter

of course you can track the time for each export/import operation and direct export/import job to write the timestamp in logfile using LOGTIME parameter. More on Expdp/Impdp LOGTIME Read Here
But if you like additional information about the job (eg. which process is doing what and taking how much time) you can use METRICS=Y parameter.
These parameters are useful to investigate datapump performance and estimate the time of similar export, import operation

METRICS
Default: NO
Syntax and DescriptionMETRICS=[YES | NO]

An Example
$ cat exp_full_pdb01.par
DIRECTORY=DUMP
DUMPFILE=EXP_PDB01_FULL%U.DMP
LOGFILE=EXP_PDB01_FULL.LOG
SCHEMAS=TEST
REUSE_DUMPFILES=Y
FLASHBACK_TIME=SYSTIMESTAMP
METRICS=Y

How to Power On/off Oracle Exadata Machine

<<Back to Exadata Main Page How to Power On/off Oracle Exadata Machine Oracle Exadata machines can be powered on/off either by pressing the power button on front of the server or by logging in to the ILOM interface. Powering on servers using button on front of the server The power on sequence is as follows. 1. Start Rack, including switches Note:- Ensure the switches have had power applied for a few minutes to complete power on configuration before starting Exadata Storage Servers 2.Start Exadata Storage Servers Note:- Ensure all Exadata Storage Servers complete the boot process before starting the database servers 3. Start Database Servers Powering On Servers Remotely using ILOM The ILOM can be accessed using the Web console, the command-line interface (CLI), IPMI, or SNMP. For example, to apply power to server dm01cel01 using IPMI, where dm01cel01-ilom is the host name of the ILOM for the serve...

ORA-46630: keystore cannot be created at the specified location

<<Back to DB Administration Main Page ORA-46630: keystore cannot be created at the specified location CDB011> ADMINISTER KEY MANAGEMENT CREATE KEYSTORE '+DATAC4/CDB01/wallet/' IDENTIFIED BY "xxxxxxx"; ADMINISTER KEY MANAGEMENT CREATE KEYSTORE '+DATAC4/CDB01/wallet/' IDENTIFIED BY "EncTest123" * ERROR at line 1: ORA-46630: keystore cannot be created at the specified location Cause Creating a keystore at a location where there is already a keystore exists Solution To solve the problem, use a different location to create a keystore (use ENCRYPTION_WALLET_LOCATION in sqlnet.ora file to specify the keystore location), or move this ewallet.p12 file to some other location. Note: Oracle does not recommend deleting keystore file (ewallet.p12) that belongs to a database. If you have multiple keystores, you can choose to merge them rather than deleting either of them.

How to Switch Log File from All Instances in RAC

<<Back to Oracle RAC Main Page Switch The Log File of All Instances in Oracle RAC. In many cases you need to switch the logfile of the database. You can switch logfile using alter system switch logfile command but if you want to switch the logfile from all the instances you need to execute the command on all the instances individually and therefore you must login on all the instances. You can avoid this and switch logfile of all instances by just running the below command from any of the instance in RAC database SQL> ALTER SYSTEM SWITCH ALL LOGFILE; System altered.
