The basic use method of Oracle Statspack

Statspack Installation Use and analysis

1. View table Space

Select Tablespace_name,file_name from Dba_data_files;

2. Create Statspack table Space

Create tablespace perfstat datafile ' d:\oracle\oradata\perfstat.dbf ' size 500m

The table space should be as large as possible.

(If the table space is small, there will be an error in the installation, causing the next installation to prompt "xxx synonym (synonymous) has been installed ...", you must find the synonyms to remove, very troublesome)
