Getting dm_connect_failed Error After Timos Installation (Doc ID 1296310.1)

Last updated on AUGUST 17, 2018

Applies to:

Oracle Communications Billing and Revenue Management - Version 7.3.1.0.0 and later
Information in this document applies to any platform.

Goal

After installation of TIMOS no calls are accepted (through the AAAGw-CM-DM-DMTIMOS chain), giving "dm_connect_failed" error, with the following error messages reported in timos.log:

03.02.2011 20:22:51 xxxx dm_timos DMT CRITICAL [T:1] 00511 - (timosMgr.MemoryMonitor) SHUTTING DOWN: Reached process size limit. Size: 2008400 KB, limit: 2097152 KB
03.02.2011 20:23:00 xxxx dm_timos DMT NORMAL [T:6] 00527 - (timosMgr.TimosDataManager.AcceptorPool.NetworkListener) Info for High Availability: 'Accept client connection<60000000034cdc70>'
03.02.2011 20:23:00 xxxx dm_timos DMT NORMAL [T:12] 00527 - (timosMgr.TimosDataManager.ConnectorPool.NetworkListener) Info for High Availability: 'Connect to my.wi-tribe.pk:12950 succeeded.'
03.02.2011 20:23:01 xxxx dm_timos DMT NORMAL [T:1] 00000 - (timosMgr) INF_SYSTEM_SHUTDOWN


A similar issue is also described in <Note 565550.1> too, where it's suggested to review the process size limit set at the OS level (maxdsiz_64, on an HP-UX Itanium OS), by providing a size which fits the largest expected process size.

Below is the snapshot of the system memory:

Total VM :      4.8gb   Sys Mem :     10.6gb  User Mem:  3.4gb  Phys Mem : 31.9gb
Active VM:     4.1gb   Buf Cache:     0mb    Free Mem: 13.3gb  FileCache:  4.5gb

Actual RAM SIZE of the server: 32GB
Current Free Mem : 13GB.


Below is the current value of maxdsiz_64bit parameter. 30 -45 Calls expected per minute.

Tunable Tuning Capability Current Value Next Boot Value Default Value
maxdsiz_64bit Dynamic 2147483648 2147483648 4294967296


A suggestion is needed to fine tune this parameter.

TIMOS crashed after less than 10 minutes run time during the deployment. Even if we assume 30 calls per minute, that’s less than 300 calls before the crash. How TIMOS process can allocate 2 GB of physical memory for just 300 calls?
