RE: What's Oracle Trying to Hide ???

Steve,

"nm" parameter is used as event name. i.e what to do if that triggering event occurs.
You can set either SYSTEMSTATE or PROCESSSTATE or ERRORSTACK to dump those things.

Consider a case , you want to dump the errorstack when ORA-00060 (deadlock) occurs.
Here you use SID,SERIAL#,60,65535,ERRORSTACK.

Triggering event 65535 is IMMEDIATE .

Hope this helps.

I generally share your "speculation" but in the case of dbms_system it is referenced by other sources yet it is undocumented. If you can do a describe on it from SQL*Plus then it should be documented. So dbms_system is undocumented and incomplete but available for our use??

In dbms_system there's a procedure called "set_ev" with 5 parameters. I'm thinking this is to set events like 10046 and that the "si" parm is for SID, the "se" parm is for serial#, the "ev" parm is the event number, the "le" parm is the level. But what would the "nm" parm be and how would it be used?

I suspect that they are trying to prevent headaches by hiding 'features' that are intended for internal use only.

Sometimes a "DBA" will get hold of some undocumented feature and use it just because it's there, sometimes causing database problems in the process.

This type of behavior is common in the PC world. Just take a look at PC magazine and Windoze websites and you will find all kinds of "tips" and "tricks" that add no value to the system and usually eat up resources.

It seems that this mentality carries over from the Windoze world to those that are new with Oracle, and the "DBA" starts twisting and turning every knob available.

Kind of messes things up for times when one of those undoc features might be useful.

This may be pure speculation on my part , but it's my story, and I'm sticking to it.

Here's a paste from the $ORACLE_HOME/rdbms/admin/dbmsutil.sql script:

Rem  dbms_system           - database system level commands (moved to
Rem                          prvtutil.sql for more obscurity)

Not only do they want to "obscure" the dbms_system package but I can't find the prvtutil.sql script. Where is this stuff and why do they want to hide it? Any ideas?

...Just found the ./rdbms/admin/prvtutil.plb file and now I'm wishing I could un-"wrap" this "present" on boxing day!
