1) What tasks do you perform on daily basis as a DBA?
The day of an Oracle DBA starts with checking emails that will have details on support tickets raised from customers for that day
Based on the issue escalated, we need to contact the personnel and collect the needed data. Lets say for example if the issue is generic stating that system is slow owing to database we first need to collect the reports from database for the specified timeframe. This will include logs like traces, alert.log, AWR , ADDM performance reports, tkprof output for specific sql etc
Second main thing a DBA should do on daily basis is to check and make sure RMAN backups are valid. If the environment is big typically full backups would have been scheduled once or twice a week. Incremental will happen twice a day or once a day. Make sure these backups are VALID. Look at rman.log the logfile onto which backup output is present
Periodically check for database statistics as part of database health check. Make sure statistics are up-to-date
Participate in disaster recovery activity that happens once in three months. This involves restore and recovery of backups from tapes, local disks etc and make sure backups are 100% VALID. This is a major business continuity practice
Work with developers who complain issue with queries. Performance tuning comes into picture here
Create users based on request from managers for new joiners. Remove database user accounts of employees who have left the employer
Participate in security audit and make sure the system is 100% safe and secure in compliance with law
Be part of system patching, perform clean stop and start of database as well as applications communicating with database
Patch database on as needed basis
Perform evaluation of critical patch updates and recommend patches in relevance to their impact on system
Evaluate upcoming version, understand new features and determine best upgrade path with minimal downtime
If the client project uses high availability solution like RAC, dataguard support such applications
Perform logical backups using tools like datapump to create test system, UAT, new dev system after a major prod upgrade
2) We have a database that is about 3TB in size. It used to take 8 hours for full backup using RMAN during weekly full backup schedule. From last week onwards this backup has been taking closer to 20 hours for completion. What is going on?
Check and make sure the incremental backups are happening properly as scheduled in between the one week timeframe
Make sure there s no change in network used for performing backup. Involve network admin to make sure there are no bottlenecks with network bandwidth
If disks are used as channel destination for storing backups work with storage admin (or) system administrator and make sure the speed of disk write is not a problem
RMAN depends on memory. During the rman job run make sure sufficient space is available in memory for RMAN jobs to run. Check and see no additional (or) new jobs run during this schedule
3) Can you have indexes on external tables?
Nope. DML operations are not allowed in external tables. We can have synonyms , views on them
4) Which database view will you make use of for checking a past performance problem?
The v$active_session_history can be made use of for this purpose
