Sessions were failing constantly due to memory issues
Could you provide more details - what are the exact error messages?

Quote:
There was huge amount of swapping going on too
Which command you use to check if swapping occurs?

Quote:
So this would mean more than 25G is consumed by PGA when failover occurs
[...]
You don't have enough evidence for now.

Quote:
when I check the PGA usage on both the instances it is around 6G per instance,
so the combined usage is less than 12G and thats the reason I am confused
And how do you check the PGA status?

Quote:
So I am not sure how to check the total memory consumption of these processes as I cannot sum them
as this might give me a false value due to child processes involved
Why do you care for child processes? What's the sum of the memory used by these processes?

lessecho

LESSECHO(1)						      General Commands Manual						       LESSECHO(1)

NAME

       lessecho - expand metacharacters

SYNOPSIS

       lessecho [-ox] [-cx] [-pn] [-dn] [-mx] [-nn] [-ex] [-a] file ...

DESCRIPTION

       lessecho  is  a program that simply echos its arguments on standard output.  But any metacharacter in the output is preceded by an "escape"
       character, which by default is a backslash.

OPTIONS

       A summary of options is included below.

       -ex    Specifies "x", rather than backslash, to be the escape char for metachars.  If x is "-", no escape char is used and  arguments  con-
	      taining metachars are surrounded by quotes instead.

       -ox    Specifies "x", rather than double-quote, to be the open quote character, which is used if the -e- option is specified.

       -cx    Specifies "x" to be the close quote character.

       -pn    Specifies "n" to be the open quote character, as an integer.

       -dn    Specifies "n" to be the close quote character, as an integer.

       -mx    Specifies "x" to be a metachar.  By default, no characters are considered metachars.

       -nn    Specifies "n" to be a metachar, as an integer.

       -fn    Specifies "n" to be the escape char for metachars, as an integer.

       -a     Specifies that all arguments are to be quoted.  The default is that only arguments containing metacharacters are quoted
