Known Issues for Installation, Upgrade, and Deployment

Known issues and workarounds for installing, upgrading, and deploying Sybase Control Center.

Change Request Number Description
700231

SCC cannot store an encrypted password for LDAP.

SCC 3.2.6 and previous releases are distributed without a keystore used to encrypt and decrypt passwords stored in the LDAPLoginModule configuration block in csi_config.xml (in SCC 3.2.6 and later) or csi.properties (in SCC 3.2.5 and earlier). This does not affect SUP because the SUP distribution includes the keystore in question.

Workaround: None.

SCC does not support downgrade from a newer release to an older release.

Workaround: If you need the ability to roll back an SCC upgrade, back up the SCC installation directory (SCC-3_2, SCC-3_1 , or SCC-3_0) before you upgrade.

Cannot deploy a second SCC server instance on the same host.

An error appears in agent.log:
2011-07-14 16:39:21,131 [ERROR] [asa.ASAInstanceManagerService                ] 
[Agent Bootstrap Thread] - com.sybase.ua.service. AgentServiceException: Failed to start database 
engine com.sybase.ua.services.asa.ASAEngine$InvalidConnectionException: The connection to 
scc_repository is not valid.  The file location  
/net/hmoconc/omni/cisqa/skibba/sccinstance_test/sybase/SCC-3_2/instances/sccnhrh564d.
sybase.com/services/Repository/scc_repository.db does not match the file location specified in 
the service-config.xml (/net/hmoconc/omni/cisqa/skibba/sccinstance_test/sybase/SCC-
3_2/instances/instance2/services/Repository/scc_repository.db). This may indicate that another 
SCC repository server is running from a different installation directory and the connection is 
being made to the wrong server instance. Check to make sure any SCC repository servers running 
on the network each have a unique server name and tcp port.

This problem does not occur if one of the instances is an SCC agent, which is a more common scenario.

Workaround: Sybase does not recommend running more than one SCC server instance on a single host computer in a production environment. To enable a second server instance in a test or development environment:
  1. On the second SCC server instance, open this file:

    SCC-3_2/instances/<instance2>/services/SccSADataserver/service-config.xml

  2. Locate this line:
    <set-property property="com.sybase.asa.server.name" value="scc_repository" />
    
  3. Change scc_repository to something different, such as scc_repository2 or scc_repository_instancename.
  4. To display SCC ports that are in use, enter:
    scc --info ports
  5. See Configuring Ports in the online help for instructions on using the scc --ports command to reassign the ports on the second SCC instance. The two instances must use different ports.

Sybase Control Center fails to start because it does not have enough memory.

Workaround: For instructions on adjusting memory, see Get Started > Launching Sybase Control Center > Configuring Memory Usage in the SCC online help.

In UNIX, you can also execute this command before starting SCC, or add it at the beginning of SCC-3_2/bin/scc.sh:
ulimit -v 59326240

The command increases the virtual memory available to Sybase Control Center.
