12.2.0.1 : Too many process on new primary (switchover)

Hi ,

After a switchover to standby (dgmgrl) ,

I noticed too many ( more than 300) process named :

oracleDBPRD

(DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))

but on old PRIMARY (that become standby)

, I noticed only 10 same process named (before switch) :

oracleDBPRD

(DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))

Any explanation for this ?

Regards.

GD.
