Autosys instance is down i event_demon log you can see with the message
CAUAJM_E_00051 Unable to create thread! [0xb8a01c58]:Resource temporarily unavailable
WAAE 11.3 on LINUX
The message "CAUAJM_E_00051 Unable to create thread! [0xb8a01c58] Resource
temporarily unavailable" is usually related to either the user under which
the process is running cannot create a thread or it does not have enough memory
or file descriptors to create the thread.
This can be related to the Oracle client libraries not freeing memory and causing
the process to use to much memory.
You can define the SCHED_SCALE and DB_CONNECTIONS parameters to tune the scheduler.
On UNIX, the SCHED_SCALE and DB_CONNECTIONS parameters are operating system environment
Depending on your UNIX operating system, you can use either the setenv or the export
command to define these tuning parameters.
To define the tuning parameters for the scheduler on UNIX
1. Log on to CA Workload Automation AE as the EXEC superuser and enter the
following command at the operating system prompt:
sendevent -E STOP_DEMON
The scheduler completes any processing it is currently performing and stops.
2. Enter the following commands at the operating system prompt based on your
UNIX shell command interpreter:
setenv SCHED_SCALE limit
export SCHED_SCALE limit
DB_CONNECTIONS can be set from 1-128.
SCHED_SCALE can be set from 1-42 .
The default value of SCHED_SCALE=5 and DB_CONNECTIONS=16.
DB_CONNECTIONS is almost three times the value of SCHED_SCALE.
Based on the above defaults and the code implementation we provided you
with the formula DB_CONNECTIONS=(SCHED_SCALE*3 + 1).
The formula cannot be taken literally when touching the upper limits.
Incase you are seeing any performance delays with the current SCHED_SCALE
you can increase the value beyond 42, while restricting DB_CONNECTIONS to
128. But as increase the value of SCHED_SCALE, AutoSys will use increased
number of system resources and could hit the ceiling on your system.
With DB_CONNECTIONS having a limit of 128 this means we should not increase
SCHED_SCALE past 42, although this has a maximum value of 64.
3. restart the scheduler
