RMS infrastructure now reads the configured pid Max from /proc/sys/keâ¦
â¦rnel/pid_max
but limits it to a maximum of 128K. It can be overridden by "PID_MAX"
environment
variable in ms.env.
If the PID_MAX variable is set to 0, 64K is assumed to be configured pid
max.
If the PID_MAX variable is set to less than 32K, then 32K is assumed to be
configured pid max.
When a SQL process has a pin greater than the configured pid max, an error
message
"Pid , is higher than the configured pid max <configured_pid>" is written to
the SQL log file and disables RMS for those processes. Node won't be
brought down.
"Get Statistics for rms " shows the the configured pid max.
The environment variable to set the size of RMS shared segment size is now
changed to RMS_SHARED_SEG_SIZE_MB.
genms change for controlling pid_max and rms shared segment size
