KNOWN ISSUES

Avoiding CICS Temporary Storage Problems

Set up timeouts in VBI to avoid temporary storage problems:
1. In the JCL provided in 'ATTMF.VBI.V3R10.INSTLIB(VBIUCFG)', set the timeout values as small as possible.
2. Submit the following JCLs in this order:
  'ATTMF.VBI.V3R10.INSTLIB(VBIUCFG)'
  'ATTMF.VBI.V3R10.INSTLIB(VBIUCNVT)'
  'ATTMF.VBI.V3R10.INSTLIB(VBIUSRVR)'
When you customize and submit the JCL to optimize CICS Temporary storage, you ensure that if the mid-tier development does not disconnect sessions properly, the CICS Temporary Storage queues associated with run-time sessions on the mid-tier won't exhaust CICS Temporary Storage Queues in the installed CICS region.
Using VBI APIs without incurring temporary storage problems
You can develop VBI client runtime code on the mid-tier so that each session issues a Disconnect() API when the session has completed it's tasks. This prevents stranded CICS Temporary storage queues from negatively impacting performance.

VBI Compliance with New RACF Security Rules

The new RACF security rules provide for mixed case passwords. These VBI 3.1 API methods are compliant with this development:

ConnectBridge
ChangePassword
QueryLoadModuleInformation

Any userID or password information collected in custom developed 3270 applications on the host must make sure that the terminal is operating with a 3270 model terminal defined with a TYPETERM that allows for mixed case. Also, you should only shift userID and password to upper case if the RACF rules for passwords that are in effect in that CICS region require passwords to be in upper case. If there are too many incorrect sign-on or verification attempts when executing the security related API, the RACF userID may be suspended.
