Modify repeat_interval for Auto Sync Jobs

Question

Is it "permitted/supported" to modify the repeat_interval for Auto Sync Index jobs created when using the syntax SYNC(EVERY "SYSDATE + 30/86400") which give a repeat interval of 30 seconds
I do not want to have partitions older than a (sysdate-3) days and none greater than "sysdate" to be running. I create new partitions daily and so would like to start/stop partition jobs for the sync window. If I get data outside the window, say 7 days old, then I would run that specific partition sync manually.
Is there a way to define the interval to be a moving window?
Regards

Answer 1

There is a Job created for each partition. There is a repeat_interval parameter set for the Job from the SYNC(EVERY ...) The memory and degreel_parallel parameters go into the Job PLSQL definition
If you change the index then the value in the parameters column from user_ind_partitions only has the most recent value (it seems) and eventually it can get confusing.
REPEAT_INTERVAL is a JOB thing and modifying that works just as well **and** keeps the parameters values intact as when the index was created.
Also, I found **and** it could be something in the syntax I had, that if I had loaded data and the job had not kicked in yet, I could not modify the index for any partition. We load data continuously and we have daily*4 partitions (for 5 years). So quite a few partitions and Jobs. Disabling a Job would be much simpler.
