    Question Archival Error, no source redo log file

    Dear all,

    I just start to be an Oracle DBA. When I checked the alert log file this morning, I found the following error message in the alert log file. Could you please give me some clue to solve the issue? I do appreciate.

    My understanding is: in my primary database, no redo log file /u05/arch/1_3907.dbf exists, so there is no way for standby database to archive the log file. Am I right? What should I do?

    you have a standby database and the standby needs a log that likely you already removed where it thinks it should be /u05/arch/

    Thanks for your help, stmontgo.

    Another new "DBA" like me deleted all the files in dicrectory /u05/arch on the standby. So does that mean I have to create a log file with the same name? If so, could you tell me the steps of creating a log file? I do appreciate your help.

    Well the thing is there was a gap detected in the sequence of archive logs to applied at the standby - namely among others /u05/arch/1_3904.dbf. The standby is not being kept current and will not be until you can retrieve the missing logs. If you cannot retrieve the missing logs you need to recerate the standby with a new backup from production.

    Hi stmontgo,

    May be this is stupid question, can I retrieve the miss log from the back up tape? If so, how could I reach the tape drive in Linux?

    And if I couldn't find the miss log, is there any drawback to create a new standby?

    Thanks for your patience and time.

    ask you SA as they probably control your backup software

    no downside to recreating the standby, apart from the hassle of doing it if you have no experience

    You are going to need to have this "under your belt" anyway, since recreation is needed if ever you restore & partially recover the primary or when you test the activation of the standby. Whoever first created the standby should have left instruction on how to do it.

    Dear all,

    Another junior DBA suggested me to solve the issue in this way:

    1. shut down the primary database and clean all the logs.

    2. shut down the standby database and clean all the logs.

    3. start and mount the primary database and standby database.

    Could anybody tell me whether it is a good way? Is there any risk? After the above steps, should we create the log on both databases and how could we create the log file matched on both database? Thank you for your help in advance.

    Jian

    no, your standby needs to be be in sync with the primary with missing lpgs it cannot do that.

    Do this.

    Shutdown primary and standby

    remove current standby

    backup and restore primary onto standby machine

    open up standy in standby mode.

    Can't invent logs which it needs
