Usage of DB_FILE_NAME_CONVERT

 DB_FILE_NAME_CONVERT = 'string1' , 'string2' , 'string3' , 'string4' , ...

Where:

  • string1 is the pattern of the primary database filename

  • string2 is the pattern of the standby database filename

  • string3 is the pattern of the primary database filename

  • string4 is the pattern of the standby database filename

You can use as many pairs of primary and standby replacement strings as required. You can use single or double quotation marks.

The following are example settings that are acceptable:

DB_FILE_NAME_CONVERT = '/dbs/t1/','/dbs/t1/s_','dbs/t2/ ','dbs/t2/s_'


DB_FILE_NAME_CONVERT is useful for creating a duplicate database for recovery purposes. It converts the filename of a new datafile on the primary database to a filename on the standby database. If you add a datafile to the primary database, you must add a corresponding file to the standby database. When the standby database is updated, this parameter converts the datafile name on the primary database to the datafile name on the standby database. The file on the standby database must exist and be writable, or the recovery process will halt with an error.


*.db_file_name_convert='/apptrngrt/product/oradata/CDBEBSDV','/ordascn7i/product/oradata/CDBEBSDV'

*.log_file_name_convert='/apptrngrt/product/oradata/CDBEBSDV','/ordascn7i/product/oradata/CDBEBSDV'

How to fix Oracle SQL Developer connection issue "Got minus one from a read call"

If you don 't want to disable this, you can put the machine names as follows: tcp.invited_nodes=(machine1, machine2) 3. Bounce the listener. Due to security enhancements it is not good to put tcp.validnode_checking = no or comment out will through error when we start listener like below: Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=shsebs7idb1.appsolworld.com)(PORT=1522))) TNS-00584: Valid node checking configuration error TNS-12560: TNS:protocol adapter error Better plan is to add localhost or IP address of client (Local Computer) in the sqlnet.ora file That will solve the problem NAMES.DIRECTORY_PATH=(TNSNAMES, ONAMES, HOSTNAME) SQLNET.EXPI

How to troubleshoot Long Running Concurrent Request in EBS 12.2

 The following points need to answer before jumping into troubleshooting: Are there any recent code changes done in the concurrent program?           Check long_running_sid and verify the recent code change of last_ddl_timestamp after a             discussion with the developer. Was this running long in the last few run as well, or was this time only?            ==> Check the program history. How much time does it take to complete?           Once again program history can give us some idea. Are these jobs fetching higher data compared to the last run           ===> Confirm on data change . Query Plan change will indicate this issue. Does this job runs at any specific time or it can be run anytime           ===> The nature of the job can help to understand the job's nature. Does this job fetch data using DB Link          ====> Check whether the DB link is involved or not. The below-given approach would help to conclude the gray areas. Check the load of the server using t
