Understanding meaning of ORA-44602: pageout in progress

Question

I have a logical standby database. The v$logstdby_process view has been helpful in troubleshooting different issues from time to time, but I came across a new builder condition today and wanted to see if anyone has some insight on what this status means. It's not listed in the view (v$logstdby_process) documentation. Metalink, this forum and google search do not bring anything up. Looking for an ACE to help out.
The line in question below is:
BUILDER 4,172,548 ORA-44602: pageout in progress (0 out of 1 steps complete)
SELECT TYPE,
high_scn,

Thanks in advanced

Answer 1

Thanks. I had that assumption. For the benefit of others, here is the main blurb from doc id: 312434.1
In the event that the SQL Apply engine is attempting to build a large transaction the "lcr cache" may fill up. Rather than immediately reporting an error, similar to an ORA-4031, the SQL Apply engine attempts to pageout portions of the "lcr cache" in a way similar to that of the OS paging portions of real memory. To determine if SQL Apply pageouts are occurring, the following SQL statement should be issued.
SQL> select value
from v$logstdby_stats
where name like '%paged%';
VALUE
358706176
In this example, a total of 358706176 bytes have been paged out since the SQL Apply engine was started. If pageouts are occurring on a regular basis during normal operations, then you may want to consider increasing the size of the MAX_SGA logical standby parameter.
