Memory Allocation (SGA) Improving DB Startup Time by faster SGA Allocation

• DB instance startup time depends on shared memory allocation time

• Oracle Solaris parallelizes allocation using kernel threads (VMTASKS)

– Default maximum number of vmtasks limited to 16

– On larger systems, vmtasks limit can be increased for better parallelism

– For example, add the following line to /etc/system

– or modify on a live system using mdb

• Set vmtask_ntasks_max parameter to 10-20% of available cpus

# set vmtask_ntasks_max = 0x20

# echo “vmtask_ntasks_max /W 0x20” | /bin/mdb -kw

Resize Oracle DB 12c Without Downtime

Optimized Shared Memory (OSM)

– New Oracle Solaris Optimized Shared Memory (OSM) interface - replaces DISM • Oracle Solaris 10 1/13

• Oracle Solaris 11 SRU 7.5 or later

– Works with Oracle DB Automatic Memory Management (AMM)

– Dynamic, NUMA- aware granule based shared memory

Dynamically resize your Database SGA online without a reboot

Bring Oracle Database instances up 2x faster

SGA


OSM Details Many advantages against DISM

• Allocate Shared Memory only as it is required

– Faster start-up of instance

• No services from oradism background process required

– Does not require super-user privilege

• Does not required double allocation of SWAP

• Enable: – Set MEMORY_MAX_TARGET > MEMORY_TARGET

• Check (Examine column labeled "ALLOC")
