Statspack is a preset of general performance checking and reporting utilities presented through Oracle for Oracle8i and about. A buyer is quickly made by means of the set up script - this shopper, PERFSTAT, owns all products preferred by means of this package deal. For excess written content pertaining to Statspack, go through the documentation within report $ORACLE_Property/rdbms/admin/spdoc.txt.
Fastened up Statspack
In direction of set up the deal, the two distinction in the direction of the ORACLE_Dwelling rdbms/admin listing, or carefully specify the ORACLE_House/rdbms/admin listing every time getting in touch with the mounted up script, SPCREATE.
In the direction of function the set up script, it's very important in direction of employ SQL*In addition and talk as an consumer with SYSDBA privilege. For case in point, start SQL*In addition, then:
Upon UNIX : SunOS/HP UX/Linux
SQL> Converse / AS SYSDBA
Upon Home windows: XP/NT/2000/2003
SQL> Converse / AS SYSDBA
The SPCREATE set up script operates a few alternative scripts. Those people scripts are recognized as robotically, as a result on your own do not need to have toward operate them:
* SPCUSR: Results in the consumer and grants privileges
* SPCTAB: Makes the tables
* SPCPKG: Generates the offer bundle
How just one can obtain the latest Ststapack stage?
- Seem to be at table PERFSTST.Data$SNAPSHOT
- Operate spreport.sql and your self'll awareness it alongwith the snapids mentioned
Figures$SNAPSHOT will demonstrate place for every single Snapshot recorded
complete statspack.snap (i_snap_issue=> 7, i_change_parameter=>'genuine');
Concentrations >= zero Simple Effectiveness Studies
Levels >= 5 Even further Details: SQL Promises
Ranges >= 6 Added Details: SQL Designs and SQL Software Consumption
Amounts >= 10 Even more Studies: Father or mum and Child Latches
Working with Statspack (amassing details)
-- Consider a overall performance snapshot
-- Receive a checklist of snapshots
column snap_period structure a21
opt for snap_identity,in the direction of_char(snap_period,'MON dd, yyyy hh24:mm:ss') snap_season
