Subsequent CICS User Application Transactions

For transactions after the initial transaction, the specified URL parameter might or might not be the same as that specified for the initial transaction.

The S7M3PASS component can cause a new Connection Thread to be started when the specified URL parameter is not the same, as described in the following contents.

  1. The user application issues a tibcoConnection_create with a URL (case sensitive) parameter.
  2. S7M3PASS looks for the Connection Thread for the URL:
    • a. If found (same case sensitive URL), continue to next step.
    • b. If not found (new URL), S7M3PASS tells the Master Thread to start a new Connection Thread for the new URL, then continue.
  3. S7M3PASS looks for a free Work Thread on the Connection Thread:
    • a. If a free Work Thread exists, it allocates the existing Work Thread.
    • b. If a free Work Thread does not exist, it starts a new Work Thread.
  4. S7M3PASS establishes an interface to the S7M3EMSS Work Thread for the URL and continues as previously described.
