Dear Sahad,
<PRIV> mode will be used if the work process starts to allocate heap - or private,
thus PRIV - memory. This is not necessarily a bad thing. There are two scenarios
that may lead to such a system state:
1. There is a small number of users that create huge contexts. In this case, it
will be OK to have such users allocate memory from heap and exclusively lock
a work process for them (this is a side-effect of the PRIV state, as heap memory
content can not be seen by another process, and the user context can no longer
be 'rolled' into another work process. The limit when this will happen is either given
by the ressource limit (em/initial_size_MB, EM/TOTAL_SIZE_MB) which is the
overall amount of extended memory (EM). EM is a shared memory. The other limit
is a user specific quota given by ztta/roll_extension (or ES/SHM_MAX_PRIV_SEGS
for AIX, when ES/TABLE=SHM_SEGS is used). As I said, this is normally OK, and
a small number of PRIV processes is not a problem at all.
2. The user contexts are equally big, but there is not enough EM available on the
instance. This will force EVERY user context into PRIV, as soon as the EM is
exhausted. The fact that EM is exhausted will be seen in transaction ST02 (look
for SAP Memory, Extended memory). Also check with transaction SM04, Goto,
Memory, the size of the user contexts. In this case, increasing EM, or reducing the
amount of users on the instance are your choices.
As I said, if this is only one or two work processes, you must not worry about them.
