APAR status

• Closed as program error.

Error description

• This error can occur when multiple WebSphere instances on
  different systems in a SYSPLEX are using WOLA over OTMA to
  connect to a single IMS region, or when multiple WebSphere
  instances on the same system are using WOLA over OTMA to
  connect to multiple IMS regions which share the same XCF group.
  
  Joblog contains this error:
  
  ExtendedMessage: J2CA0021E: An exception occurred while trying
  to get a Connection from the Managed Connection resource
  eis/ola :
   javax.resource.ResourceException: Error on otma_open call,
  RC = 8, RSN codes = 0 : 0 : 0 : 2
  

Local fix

• use 1 instance of WebSphere using WOLA over OTMA in a SYSPLEX
  or with IMS regions that share the same XCF group.

  ****************************************************************
  A name collision can occur when attempting to resolve the
  OTMA anchor the Optimized local adapter will use when there
  are multiple IMS servers in a sysplex with the same sever
  names. Causing an Error like the following.
  J2CA0021E: An exception occurred while trying
  to get a Connection from the Managed Connection resource
  xxx/yyy :
  javax.resource.ResourceException: Error on otma_open call,
  RC = 8, RSN codes = 0 : 0 : 0 : 2
  

Problem conclusion

• Update WOLA to prevent collisions when accessing IMS from
  WebSphere using WOLA and OTMA.
