My BMC Atrium Orchestrator (BAO) / TrueSight Orchestration peer fails to start or act properly. Possible symptoms include the following:

• BAO cannot register with BMC Atrium Single Sign-On:

SEVERE 15-09-01 01:01:01.001 com.bmc.atrium.sso.common.CertificateUtils.captureServerCert().Thread-1:Failed to connect with AtriumSSO server: javax.net.ssl.SSLException: Received fatal alert: unexpected_message
BAO peers fail to join the grid:
01 Sep 2015 01:01:01,001 [Thread=AMP - Grid Framework - Advertisement Processor - 123456] WARN TopologyParticipantProxiesManager Error occurred when connecting to peer [MyCDP] in topology [JMS_DISCOVERY] in grid [management].
  Summary: No message available. The exception was of type: java.io.IOException
  Caused by:
    Summary: connect timed out
    Caused by:
      Summary: connect timed out

• The peer takes several hours to start after this message in catalina.out:

Initializing Atrium SSO logging directory.
Atrium SSO logging directory not specified, using default.
Atrium SSO default logging directory: /opt/bmc/CDP/tomcat/logs
OpenSSO debug level not set.

• The peer does not write any information to its log files.
• Users cannot see information in the Repository or Grid Manager after they log in.

Verify that you have sufficient disk space, memory, and CPU for TSO to run. If you are not sure whether these resources are sufficient, check the System Requirements page in the documentation for your version of the TSO Platform. If these are sufficient, run this command on the TSO server to check the current entropy level:

cat /proc/sys/kernel/random/entropy_avail

This value is usually either very low (less than 100) or very higher (greater than 2000). If it is lower than 100, the server's entropy is insufficient for normal operation of TSO. To solve this problem, configure TSO to use urandom, a reliable source of random numbers, via the following steps:

1. Open the file [TSO_HOME]/jvm/lib/security/java.security.
2. Locate the line "securerandom.source=file:/dev/random", on or about line 119.
3. Change this to "securerandom.source=file:/dev/urandom", without quotes.
4. Save the file.
5. Restart the TSO peer.
