How to Monitor the Progress of move-to-asm.sh (KBA4554)

 

KBA

KBA# 4554

To monitor the progress of the move-to-asm.sh script.

There are several logs you can monitor when running the move-to-asm.sh script. Which log(s) depends on the current stage the script is running. This article will focus on when the datafiles are actually being moved to ASM via RMAN. For instructions on how to run the script please see this product documentation.
 

The first log to check will be the move-to-asm.sh_<SID>_run<PID>.log to see where in the process the script is currently. This log is found in the working directory of the script. Example below:

Moving database DELPHIX_DB to ASM: started at Fri Sep  6 20:59:51 EDT 2019
    db_unique_name => DELPHIX_DB
    ORACLE_SID => DELPHIX_DB
    ORACLE_HOME => /u01/app/oracle/product/12.1.0.2/dbhome_1
    Datafile diskgroup => +DATA1
    Online redo diskgroup => +REDO1
    RMAN Channels => 8

Move spfile to ASM
Move datafiles to ASM: started at Fri Sep  6 21:00:39 EDT 2019

From the example above we see that it has made it to the Move datafiles to ASM portion of the script, which is frequently the longest part of process and the stage of interest for this article. 

At this point you can log in to the database and run the following query to check the progress:

SELECT sid, opname, sofar, substr(to_char(sysdate,'dd:mon:yyyy hh24:mi:ss'),1,20) "Time Now", totalwork,time_remaining/60/60 "Time_To_Complete_Hours", round(sofar/totalwork*100,1) "%DONE", ELAPSED_SECONDS/60/60 "ELAPSED_TIME_HOURS"
FROM v$session_longops
WHERE opname LIKE 'RMAN: aggregate input%'
AND
totalwork <> 0
AND
sofar <> totalwork;
 SID    OPNAME                    SOFAR       Time Now            TOTALWORK       Time_To_Complete_Hours                       %DONE  ELAPSED_TIME_HOURS
---------- -------------------------------------------------------------------------- ------------------------------------------------------------
1138  RMAN: aggregate input   4579561088 10:sep:2019 12:54:12     5014002247               8.335                                91.3            87.8625

From the sample output above, we can tell that this part of the process is 91% complete with an expected completion time of 8.3 hours. Run the query over time to make sure it is progressing.
