PART2 - DB2 restore/recover online backup on different server

-
In the previous part 1  we restored the database to different server.
Now we will do the recovery of this database.
Below is the command used for roll forwarding the database we restored in the part 1.
This will put the database on consistent state using the logs that were included with the backup file from original host
 db2 “rollforward database ebppres to end of logs and complete overflow log path (‘/db2_main_data2/ebpplog’)” 
“end of logs” – This indicates that we are doing a full recovery instead of Point in time recovery. If point in time recovery is needed “using local time” clause need to be used also specifying the time which the recovery will end.
“complete” – This will stop the roll forward process and undo any uncompleted transactions to put the database on consistent(accessible) state. Here the use of “and” is to combine two commands. As an example above single command is same as issuing below two commands.
db2 “rollforward database ebppres to end of log”
db2 “rollforward database ebppres complete”
 
“overflow log path” – The value for this parameter should be the same location which we used as “logtarget” in restore command (ref part1 - http://dbtechno.blogspot.in/2012/12/part1-db2-restorerecover-online-backup.html). This tells roll forward process the location to find the logs required.
 Below is the output of above command for the discussed example.

The output shows the last commit point db has been recovered to and the logs used in the recovery process.
After completing these steps it is possible to connect to newly recovered database on new host.

ORA-16433: The database or pluggable database must be opened in read/write

-
Image
ORA-16433 is an error returned when a database cannot be opened. This can be a result of multiple conditions including, The inconsistency of the database Physical corruption Loss of dependent files or access issues etc.. More often than not the solution is to recover from available backups, but there can be situations where backups are not available, specially on UAT or Test setups. Although not the ideal scenario, in this type of situation you might want to open the databases even with inconsistency.  In Comes --> _ALLOW_RESETLOGS_CORRUPTION First, if you are in a position to use _ALLOW_RESETLOGS_CORRUPTION=TRUE, that means it has to be a critical moment, and when you come across more ora- errors while you are trying to reopen the databsae, that can be annoying. Note - _ALLOW_RESETLOGS_CORRUPTION=TRUE must only be used after Oracle support confirmation as a last resort. Also make sure to take cold backup before proceeding. Basic steps to be followed to resolve ORA 16433 af...

Oracle Multitenant - Create new service for PDB using DBMS_SERVICE

-
Image
When an Oracle PDB is created it starts up a default service with the PDB name. For direct connections to    PDB this service can be used. But there are situations where new service name is required in PDB level, common example is after a PDB restoration/clone, in order to enable application connections without changes in connection string. Setting service_names parameter in PDB level is not possible hence it is not an option in multitenant setup. How to create a new PDB service on Oracle 12C Check the current services, here only the default service is running, SQL> show pdbs; CON_ID CON_NAME OPEN MODE RESTRICTED ---------- ------------------------------ ---------- ---------- 3 NFACTORPDB READ WRITE NO SQL> select service_id, name, pdb from dba_Services; SERVICE_ID NAME PDB ---------- ---------------------------------------- ---------- 7 nfactorpdb NFACTORPDB SQL> ...

Wait for unread message on broadcast channel - Blocking Sessions

-
Image
What is Wait for unread message on broadcast channel wait event? Wait for unread message on broadcast channel is a wait event where source destination communication is involved and the database is waiting for a reply from remote party. Mostly this wait is seen related to data pump export (expdp) or import (impdp) operations. Although categorized in idle wait class "Wait for unread message on broadcast channel" can become the blocking session for some other sessions. Common causes for stuck sessions waiting on this wait event includes, Broken databases links, where remote database is not responding. Abnormally killed remote processes causing the sessions to wait. When a session is waiting on "Wait for unread message on broadcast channel" it can become a blocking session for dependent sessions. Most probably these sessions will be waiting on "library cache pin" or related concurrency wait events. The blocking_session column of (g)v$session view...
