SAPOSCOL : how SAP R/3 instance communicate with OS

SAPOSCOL a tiny program developed by SAP as daemon so that SAP R/3 instance can comunicate with its OS host. By using this SAPOSCOL program, SAP R/3 can communicate and can get a lot of information about OS including CPU usage, memory level usage, swap, disk activity, network information, monitored process, system configuration, client – server connectivity, etc. Hmm….we can get it without directly communicate with OS. Just use SAPGUI from your workstation.

Usually, SAPOSCOL program had to be started before your SAP R/3 instance so that it can supply your R/3 instance with OS information. To start SAPOSCOL program, your just entered your OS console/terminal and use ora[SID] (if you’re using Oracle) or SAPservice[SID] if you’re using MS SQL.

Just type : #saposcol

If SAPOSCOL process had been running, it will show you the information and status.

To stop SAPOSCOL, just type : #saposcol -k

To check SAPOSCOL information, just type : #saposcol -s
