Hi,

Please find below the cases and my thoughts on memory lock at instance level and please share your ideas on this.


case 1:

Please find the information below.This is on rac database on 10.2.0.4 on linux 64bit.

I started gathering the stats on weekednd with cronjob it gathered the stats for few tables and later after few hours I observed the job is not going forward and it is stuck.

Came to know that there is library cache lock.(same table was accessing by some other process).In this case I need to kill my job.So I killed and skipped that table and schedule the other job.Please note that though there is library cache lock it is not impacted other jobs.Only my scheduled job is halted.

Howdy, Stranger!
