SQL10004C An I/O error occurred while accessing the database directory. SQLSTATE=58031 - During DB2 Restore

-
DB2 Version – 9.5 Fixpack 3
OS – AIX 5.3
SQL10004C An I/O error occurred while accessing the database directory. SQLSTATE=58031.
This error was returned during the restoration of db backup on a new server. As per the docs and references this can be caused by several reasons including OS level permission, db and os level version etc..
But quick workaround that can be tested to resolve this error while performing a db2 restore is to try the restoration with different database directory without using the default one with the use "dbpath on" clause of db2 restore command.

 By adding "dbpath on" to the restoration command as below,
 db2 "restore database CPSDB from '/data12/backup' dbpath on '/data12/cpsjun15' into cpsjun15 logtarget '/data12/cpsjun15/log' redirect"

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

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

-

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

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...
