Event filters in library DIAG:
------------------------------
occurence            filter to implement counting for event checks
callstack            filter to only fire an event when a function is on the stack
eq                   filter to only fire an event when a == b
ne                   filter to only fire an event when a != b
gt                   filter to only fire an event when a > b
lt                   filter to only fire an event when a < b
ge                   filter to only fire an event when a >= b
le                   filter to only fire an event when a <= b
anybit               filter to only fire an event when (a & b) != 0
allbit               filter to only fire an event when (a & b) == b
nobit                filter to only fire an event when (a & b) == 0
bet                  filter to only fire an event when b <= a <= c
nbet                 filter to only fire an event when a < b or a > c
in                   filter to only fire an event when a is equal to any b .. p
nin                  filter to only fire an event when a is not equal to any b .. p
streq                filter to only fire an event when string s1 = s2 (up to  characters)
strne                filter to only fire an event when string s1 != s2 (up to  characters)
tag                  filter to only fire an event when a tag is set

Event filters in library RDBMS:
------------------------------
wait                 filter for specific wait parameters and wait duration
process              filter to set events only for a specific process
px                   filter to check identity of the process for fault injection

Event filters in library GENERIC:
------------------------------
errarg               filter to set error events only for a specific error argument

Filters must be enclosed by curly brackets. For example pgadep below: 

SQL> ALTER SESSION SET EVENTS 
'sql_trace[SQL: 32cqz71gd8wy3] {pgadep: exactDepth 0}
plan_stat=all_executions,wait=true,bind=true';
pgadep is the PGA depth (dep=N) in a trace file. It can take the following values:

For example: 

{pgadep: exactDepth 0}

For normal statement execution:

For PL/SQL statement execution:
