IC64804: A MANAGED TIVOLI STORAGE MANAGER SERVER MAY CRASH ON A SELECT AGAINST THE SCRIPT_NAMES TABLE

APAR status

• Closed as program error.

Error description

• In a Tivoli Storage Manager enterprise environment, following
  SELECT command can crash the managed server in case the scripts
  defined on the configuration manager have an EMPTY description
  (example: define script test_script_with_empty_desc desc=''):
  select name,description,chg_time,chg_admin,profile from
  script_names
  
  If the script has been defined without any description (define
  script test_script_without_desc) or with a filled description
  (define script test_script_with_desc desc='Test'), the SELECT
  will not crash the managed server.
  
  Customer/L2 Diagnostics:
  If the SELECT command is issued using a Tivoli Storage Manager
  administrative command line, following will be seen in the
  dsmerror.log file:
  11/24/2009 08:44:21 cuGetAdmCmdResp: Received a communication
  read error: rc: -50

  Steps to recreate:
  0.) Setup enterprise configuration as described in the Tivoli
  Storage Manager server 6.1 Administrator?s Guide (for example
  SC23-9773-01)
  
  On configuration manager:
  1.) Define some scripts
  => define script test_script_with_desc desc='Test'
  => define script test_script_without_desc
  => define script test_script_with_empty_desc desc=''
  
  2.) Run "q script"
  => this returns the defined scripts
  
  3.) Run "select name,description,chg_time,chg_admin,profile from
  script_names"
  => this returns the defined scripts
  
  4.) Run "notify subscribers"
  
  
  On the managed server:
  1.) Run "q script"
  => this returns the scripts as defined on the configuration
  manager
  
  2.) Run "select name,description,chg_time,chg_admin,profile from
  script_names"
  => the managed server crashes
  
  
  Tivoli Storage Manager Versions Affected:
  Tivoli Storage Manager 6.1 servers on all supported platforms.
  
  
  Initial Impact:
  Medium
  
  
  Additional Keywords:
  zz61 TSM dump SQL crashing dumping managed object
  

Local fix

• Use the QUERY SCRIPT command on the managed server to get
  information about the scripts, or use/update the scripts on the
  configuration manager with a filled description or no
  description at all.
