Using Autosys 11.0 SP5 on A64/HP

 

PROBLEM DESCRIPTION:

----------------------------------------

 

 

AutoSys processes scheduler and application server stop functioning correctly

Client utilities ( jil, chk_auto_up etc) are impacted.

 

$ chk_auto_up

______________________________________________________________________________

 

CAUAJM_E_10527 Timed out waiting for response from the Unicenter AutoSys JM Application Server. [deruspw3:9010]

CAUAJM_E_50033 Error initializing tx subsystem: CAUAJM_E_10062 Failed to get initial configuration from Unicenter AutoSys JM Application Server(s)

 

the  as_server.$AUTOSERV file is filled with the following message

09/09/2015 08:57:27] CAUAJM_E_00051 Unable to create thread! [42a20438][0]:Resource temporarily unavailable

 

RESOLUTION:

---------------------

Follow the instructions below:

 

On HP itanium machines, processes running under PA-RISC can only

 

create upto 85 threads with the default OS settings.

 

For processes to be able to create more threads the following

 

configuration settings are required.,

 

1. Set kernel parameter (this requires a reboot)

 

pa_maxssiz_32bit=268435456

 

2. Create a file '.ariesrc' in the home directory of the owner of

 

autosys binaries (eg., user autosys) and enter the following

 

lines.,

 

/opt/CA/UnicenterAutoSysJM/autosys/bin/event_demon -heap_ssz 45056

 

/opt/CA/UnicenterAutoSysJM/autosys/bin/as_server -heap_ssz 45056

 

Note:

 

=====

 

In the above example the path '/opt/CA/UnicenterAutoSysJM' points to

 

$AUTOSYS.

 

Please change the path accordingly based on $AUTOSYS on your system.

 

3. Restart application server and scheduler.
