This document covers the following topics:
When you start a Broker ACI application program, the ACI service program
searches your library list for the Security Exit service SECUEXIT. If it is
found, it will be used automatically.
In this delivery package, a Security Exit named X_SECUEXIT is provided
by Software AG. However, this file does not match the required name SECUEXIT.
So by default, the Broker ACI runs without using a Security Exit.
To use the Software AG-supplied Security Exit Program
Rename the *SRVPGM-type program X_SECUEXIT to SECUEXIT and
Start your user application. The bound Broker ACI will find and use the exit.
For detailed information, see Sample Security Exits for Broker Security.
A user-supplied security exit must meet the following minimum requirements:
| Entry points |
etbueva etbupre |
| Service program exports |
STRPGMEXP PGMLVL(*CURRENT)
LVLCHK(*NO)
EXPORT SYMBOL('etbupre')
EXPORT
SYMBOL('etbueva')
ENDPGMEXP
Sample: |
| Calling convention |
... int etbueva(ETBCB *pEtbCb, void *pEncBuf, void *pReserved, char *pErrTxt) ... int etbupre(ETBCB *pEtbCb, void *pSndBuf, void *pReserved, char *pErrTxt) Sample source: |
| Create a Service Program for a security user exit | Sample source: EXASRC(EXACRTSXIT) This CL procedure creates module SECUEXIT from a C source and binds
it to the service program SUEXIT.
|
To create a security exit program
Write the source code, include the necessary encryption and
decryption algorithms. The supplied C example SECUEXIT provides a framework for
the basic functionality.
Create a source file of the type *BND for the
service program
exports (see Creating your own Security Exit Program.
Compile the source code.
Create the service program.
See the CL Program sample EXACRTSXIT that contains the relevant
commands (CRTCMOD and CRTSRVPGM) for compiling and creating a service program.
In that example a service program named SUEXIT is created.
Usually, the Software AG-supplied security exit is named X_SECUEXIT.
If you have previously renamed it SECUEXIT, rename it back now to X_SECUEXIT
for backup reasons.
Then rename the security exit service program SUEXIT you have just
created to SECUEXIT.
Test the application. When you start your application program, the
Broker ACI automatically finds and uses the Security Exit SECUEXIT.
The samples above are based on C examples. For other languages such as ILE COBOL and ILE RPG, use the respective compiler.
To request a log file from the Broker stub, the environment variable
ETB_STUBLOG must be set. The value of this variable defines how detailed the
log will be.
The following table describes the trace
values for ETB_STUBLOG:
| Trace Value |
Trace Level | Description |
|---|---|---|
| 0 | NONE |
No tracing. |
| 1 | STANDARD |
Traces initialization, errors, and all ACI request/reply strings. |
| 2 | ADVANCED |
Used primarily by system engineers, traces everything from level 1 and provides additional information - for example the Broker ACI control block - as well as transport information. |
| 3 | SUPPORT |
This is full tracing through the stub, including detailed traces of control blocks, message information, etc. |
To evaluate error conditions
Set the environment variable: run the program EXASETENV or use the
command:
ADDENVVAR ENVVAR(ETB_STUBLOG) VALUE(3)
To change the value of the variable, use the command WRKENVVAR or
change and recompile the source file in EXASRC.
Re-run the example programs.
The member names in the file LOG are created with the prefix ETB and the six-digit process ID (ETBpppppp).
Note:
The file will be overwritten if you restart your application in
the same session.
