Hello All,

 

To increase the Oracle performance, we are planning to execute the below commands at OS level during non business hours in ECC, BW and GRC systems.

 

1) brconnect -u / -c -f stats -t system_stats

 

2) brconnect -u / -c -f stats -t oradict_stats

 

3) brconnect -c -u / -f stats -t all -f collect -p 4

 

 

Is there any sequence to follow to execute these below 3 commands in ECC/BW and GRS systems.

 

Please let us know whether we need to follow any procedure before executing the above 1 and 2 command. Also let us know whether we can schedule these 3 commands once in three months. Please advise us

 

Regards

Subbu

Question:

why do you want to execute them at OS level?

Use DB13 to schedule the number 3, it is a standard that should be scheduled every day (the parallel option should depend on the amount of power your system has and the load at night)

Set the parameters STATS_DICT_CYCLE and STATS_SYSTEM_CYCLE on the init<sid>.sap and the commands 1 and 2 will be automatically done by the 3rd command after the amount of days indicated on the parameters (recommended 3 months) take a look at the note 1235952 were they are explained.
