■ When you use SPFILE,
Setting procedure:
1. Check the current event setting status:
SQL> show parameter event;
2. Add an event and set it up:
If there is no existing event, it is set as follows:
SQL> alter system set event = '235 errorstack (3) systemstate (10)' scope = spfile;
If there is an existing event, add it and set it as follows:
For example, if there is already an event of "902 errorstack (3) systemstate (10)" as a result of the above "1"
SQL> alter system set event = '902 errorstack (3) systemstate (10): 235 errorstack (3) systemstate (10)' scope = spfile;
3. Just to be sure, I will get a backup of SPFILE:
Example of execution:
SQL> create pfile = '/ home / oracle / pfile.ora' from spfile;
4. Restart the database.
To disable it:
1. Delete event 235:
If there is no existing event, it is set as follows:
SQL> alter system set event = '' scope = spfile;
If there is an existing event, restore the original value:
For example, if there is already an event "902 errorstack (3) systemstate (10)" before this event setting,
SQL> alter system set event = '902 errorstack (3) systemstate (10)' scope = spfile;
2. Restart the database. In case
■ When you use PFILE,
Setting procedure:
1. Check the line related to "*. Event" with the cat command in the contents of PFILE.
2. Add and configure event 235:
If there is no existing event, please modify it as follows:
*. Event = '235 errorstack (3) systemstate (10)'
The existing event will be appended and set as follows:
For example, if the event of *. Event = '902 errorstack (3) systemstate (10)' already exists as a result of the above "1"
In some cases,
*. Event = '902 errorstack (3) systemstate (10): 235 errorstack (3) systemstate (10)'
3. Restart the database.
To disable it:
1. Correct the line related to "*. Event" to the contents of PFILE.
If there is no existing event, it is set as follows:
*. Event = ''
If there is an existing event, restore the original value:
For example, if there is already an event of *. Event = '902 errorstack (3) systemstate (10)' before this event setting,
*. Event = '902 errorstack (3) systemstate (10)'
2. Restart the database.
