When this amount is exceeded, a work process is restarted after completing a transaction step. This value specifies the memory amount in bytes. Normally this limit would be much smaller than the heap size to avoid that all WP's claim and hold max heap memory.ĭocumentation from RZ11 Parameter Description This was a parameter introduced as a "tripwire" that should indicate at which level of memory consumption a work process should be cleaned and memory released. Small comment to memory drawing and reference to parameters:Ībap/heaplimit is not a limitation to the heap size. ST05 is used to identify the expensive SQl statements and explain about the SQL statements.Ĭan refer to different SAP Notes for more detailed information.These are explicitly switched on the system to trace/track either a user missing authorization, en queue issues, rfc issues, sql issues, kernel issues etc. The developer traces are logged in work directory by default to work directory.The system logs by default in usr/sap/SID/DVEBMGS00/log/SLOG00 without any initiation.If the memory is not released then we use command “ipcrm” or use “cleanipc” to release the memory blocked at OS level. “top” command in Linux to see all the processes, used memory, free memory etc.If there is only one instance then by default it takes the complete memory.It is used to configure the physical memory, if more than one instance is configured.NOTE-: The long memory programs/ transactions can be split into Variants (monthly) and schedule to run the background during off peak hours. Rdisp/max_priv_time=60 secs to terminate the processes that are in PRIV mode. Restrict the processes that goes into wp PRIV mode by using parameter “rdisp/wppriv_max_no=1 or 2” Kill the process then use task manager or kill command on unix.Identify the process that has been logged for longer time.Check the system status using DPMON/SAPMMC.Question-: Users complain that they could not access the system users are encountering the hour glass mode, SM50/SM66/SM21 are not accessible. The work process cannot be terminated by the parameter “rdisp/max_wprun_time” when a work process enters PRIV mode, it remains connected to the user until the user ends the transactions or it is timed out by the system due to the memory or explicitly logged out using SM04/DPMON.
