Avoiding CICS Temporary Storage Problems

Included here are descriptions of how to avoid running low on temporary storage in Verastream Bridge Integrator (VBI).

• Set up timeouts in VBI to avoid temporary storage problems:

Verastream Bridge Integrator Compliance with New RACF Security Rules

The new RACF security rules provide for mixed case passwords. These VBI 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.

Additionally, 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.
