# Steps to follow in the installation

## Obtaining the libraries <a href="#toc66160996" id="toc66160996"></a>

Whenever possible, IEBCOPY-format files will be obtained via Editran, which will be dumped into the corresponding libraries, verifying that their contents match the list of modules indicated above.

## Compilation of MFSs <a href="#toc66160997" id="toc66160997"></a>

The formats will be assembled, adapting them to the installation's devices (DEV).

## Generation of IMS and DL/I

In IMS, the transactions, programs and databases will be generated as indicated below. The PSBs, DBDs and ACBs will be built, as well as the dynamic allocation of the databases. Using the result of the generation of databases, the source files for the CLUSTERs will be prepared for the next step.

### **IMS Definitions**

#### **Database**

* Control database for Key Management ZTBPDGCD (HIDAM)

```
DATABASE DBD=ZTBPDGCD
DATABASE DBD=ZTBPDGCI
```

**Transactions and programs**

* ZTBD. Transaction for the Key Management Administrator/Operator.

```
   APPLCTN  PSB=ZTBPOGC0                                               
     TRANSACT  CODE=(ZTBD),EDIT=(ULC),                                 *
               PRTY=(7,10,3),                                          *
               MSGTYPE=(SNGLSEG,RESPONSE,20),                          *
               MODE=SNGL,SPA=(2000)                                    
```

It must be authorized to issue the /start region command and to query RSA keys in the ICSF

* ZTBH. Interface with the Key Management procedures.

```
APPLCTN  PSB=ZTBGEAGC,PGMTYPE=(BATCH)                
   TRANSACT  CODE=(ZTBH),                             
             MSGTYPE=(SNGLSEG,NONRESPONSE,20),MODE=SNGL
```

* Program ZTBGEGC0.

```
 APPLCTN  PSB=ZTBGEGC0,PGMTYPE=(BATCH),SCHDTYP=PARALLEL         
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.editran.onesait.com/documentacion-editran/ibm-editran-v5.3-ims-en/gestor-de-claves/elementos-del-sistema-onesait-editran-gc/pasos-a-seguir-en-la-instalacion.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
