MOM Procedure
(Superseded by PROCESS_GETINFOLIST_
•
Calling MOM from a high-PIN process
If the mom of the calling process is a high-PIN process, MOM returns a synthetic
process ID. A synthetic process ID contains a PIN value of 255 in place of a high-
PIN value, which cannot be represented by 8 bits.
•
Calling MOM from a remote process with a long process name
If the mom of the calling process is a named process on a remote node and has a
process name consisting of more than five characters, the call to MOM fails: a TNS
Guardian process terminates with a limits exceeded trap (trap 5); an OSS or native
process receives a SIGLIMIT signal.
OSS Considerations
By default, an OSS process does not have a mom process; therefore, zeros are
returned in
process-id. An OSS process can have a mom process if it was created
by one of the OSS
tdm_spawn set of functions, the tdm_fork() function, or one of
the
tdm_exec set of functions; see the reference pages either online or in the Open
System Services System Calls Reference Manual for details. An OSS process does
have a mom process if a mom process has been explicitly assigned by either the
PROCESS_SETINFO_ or STEPMOM procedure.
