### Example CONFIG BASIC Statement

Source: https://www.ibm.com/docs/en/apafz/16.1.2/index_topic=analyzer-started-task-configuration-settings

Provides an example of a CONFIG BASIC statement, as found in the predefined CAZCNFG0 member. This example demonstrates the configuration of basic settings like STCid, HLQ, UNIT, and CheckpointDSN, including comments explaining each parameter.

```JCL
CONFIG BASIC                 // Basic settings:
   STCid=CAZ0                // . Application Performance Analyzer instance ID
   HLQ=CAZ0                  // . DSN high level qualifier
   UNIT=SYSDA                // . unit name for new data sets
   CheckpointDSN='.CHKP';    // . checkpoint file DSN
                             // (appended to HLQ)

```

### JCL Setup for Application Performance Analyzer Batch Interface

Source: https://www.ibm.com/docs/en/apafz/16.1.2/index_topic=commands-sample-jcl

This JCL snippet configures the Application Performance Analyzer's Batch Interface to create a new measurement request. It specifies the program to execute, library for authorization, output for messages, and the input JCL statements defining the measurement job's parameters, including its name, activation status, sampling rate, duration, and a descriptive text. Ensure to replace `_hlq_` with your installation's high-level qualifier and `CAZ0` with your Application Performance Analyzer started task name if necessary.

```jcl
//SAMPJOB1 JOB (job parameters)
//* 
//CAZBATCH EXEC PGM=CAZBATCH,PARM='STCID=CAZ0'
//STEPLIB DD DISP=SHR,DSN=hlq.SCAZAUTH
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
NEW JOBNAME=APPJOB01
ACTIVE=NO
SAMPLES=5000 DURATION=30
DESCR='Sample request for APPJOB01'
;
/*

### Example MVS START Command for CICS/Db2 Measurement

Source: https://www.ibm.com/docs/en/apafz/16.1.2/index_topic=commands-using-mvs-start-command-schedule-new-measurement

This example demonstrates how to use the MVS START command to initiate a CICS/Db2 measurement. It specifies the SYSIN PDS member 'CAZNEWCI' and sets the STC and JOBN parameters for the measurement. This command utilizes the APARM parameter to pass these options to the CAZSTART EXEC.

```MVS Console
S CAZ$NEW,APARM='MEMBER=CAZNEWCI STC=CAZ0 JOBN=CICS54A'
```

### Mount zFS File System - JCL Example

Source: https://www.ibm.com/docs/en/apafz/16.1.2/index_topic=program-directory

This JCL snippet demonstrates how to mount a zFS file system. It specifies the data set name, mount point, access mode, and type. Ensure OMVS and zFS are active on the driving system before execution. The recommended mount point is /usr/lpp/IBM/apa/v15r1.

```JCL
MOUNT FILESYSTEM('**#dsn**')
 MOUNTPOINT('**/usr/lpp/IBM/apa/v15r1**')
 MODE(RDWR)        /* can be MODE(READ) */
 TYPE(ZFS) PARM('AGGRGROW') /* zFS, with extents */

```

### Specify JVMTI agent with System ID (BPXBATCH)

Source: https://www.ibm.com/docs/en/apafz/16.1.2/index_topic=j9vm-specify-jvmti-agent

This example shows how to specify the system ID of the Application Performance Analyzer started task when using the -agentpath parameter in JCL with BPXBATCH. This is useful when multiple started tasks are operating on the system.

```jcl
//STEP EXEC PGM=BPXBATCH,
//PARM='sh java –agentpath:/usr/lpp/apa/v14r2/libCAZJTA14.so=CAZ1 prog’
```

### Copy Sample Installation Jobs using IEBCOPY

Source: https://www.ibm.com/docs/en/apafz/16.1.2/index_topic=program-directory

This JCL job uses the IEBCOPY utility to copy sample installation jobs from a source data set to a target JCL library. It selects specific members to be copied, such as CAZWSMPE, CAZWRECV, CAZWALOC, and CAZWZFS. Ensure to update the placeholder values for input and output data set names and volume serials.

```JCL
//STEP1    EXEC PGM=IEBCOPY
//SYSPRINT DD SYSOUT=*
//IN       DD DSN=IBM.HAD0F10.F4,
//            DISP=SHR,
//*           VOL=SER=**filevol**,
//            UNIT=SYSALLDA
//OUT      DD DSNAME=**jcl-library-name**,
//            DISP=(NEW,CATLG,DELETE),
//            SPACE=(TRK,(20,10,5))
//*           VOL=SER=**dasdvol**,
//            UNIT=SYSALLDA
//SYSUT3   DD UNIT=SYSALLDA,SPACE=(CYL,(1,1))
//SYSIN    DD *
     COPY INDD=IN,OUTDD=OUT
     SELECT MEMBER=(CAZWSMPE,CAZWRECV,CAZWALOC,CAZWZFS)
     SELECT MEMBER=(CAZWISMK,CAZWDDEF,CAZWAPLY,CAZWACPT)
/*

```

### Configure Load Libraries and Directory Paths

Source: https://www.ibm.com/docs/en/apafz/16.1.2/index_topic=descriptions-new

LIBS specifies additional load libraries (up to 10 data set names) to be searched. DIRS specifies HFS directory paths (up to 440 bytes) for searching relative path names. LIBS and DIRS are mutually exclusive.

```shell
LIBS=(USER1.LOADLIB,TEST1.LOADLIB)
DIRS=("/u/axx01 /u/axx01/cpp")
```

### Delete Prior Release - SMP/E JCL Example

Source: https://www.ibm.com/docs/en/apafz/16.1.2/index_topic=program-directory

This JCL provides an example of using SMP/E commands to delete a prior release of Application Performance Analyzer (e.g., HAD0E20) before installing a new version in the same Target Zone. It includes steps for receiving a dummy function, applying it, and accepting it, followed by UCLIN commands to delete the SYSMODs. This is crucial to prevent abends during the APPLY phase.

```JCL
//SMPPTFIN DD *
++FUNCTION(DUMMY01).
++VER (Z038)
  DELETE(HAD0E20).
//SMPCNTL  DD *
  SET BDY(GLOBAL).
  RECEIVE S(DUMMY01).
  SET BDY(tzone).
  APPLY S(DUMMY01) REDO.
  SET BDY(dzone).
  ACCEPT S(DUMMY01) BYPASS(APPLYCHECK) REDO .
  SET BDY(TZONE).
   UCLIN.
   DEL SYSMOD(HAD0E20).
   DEL SYSMOD(DUMMY01).
   ENDUCL.
  SET BDY(DZONE).
   UCLIN.
   DEL SYSMOD(HAD0E20).
   DEL SYSMOD(DUMMY01).
   ENDUCL.
/*

```

### SMP/E APPLY CHECK with Recommended Service

Source: https://www.ibm.com/docs/en/apafz/16.1.2/index_topic=program-directory

This snippet demonstrates how to perform an SMP/E APPLY CHECK to ensure all recommended and critical service is installed with the FMIDs. It requires receiving the latest HOLDDATA and uses specific operands like SOURCEID(RSU*) and FIXCAT(IBM.PRODUCTINSTALL-REQUIREDSERVICE).

```z/OS JCL
APPLY S(fmid,fmid,...) CHECK
FORFMID(fmid,fmid,...)
SOURCEID(RSU*)
FIXCAT(IBM.PRODUCTINSTALL-REQUIREDSERVICE)
GROUPEXTEND .

### Specify 64-bit JVMTI agent in JCL (BPXBATCH)

Source: https://www.ibm.com/docs/en/apafz/16.1.2/index_topic=j9vm-specify-jvmti-agent

This JCL snippet demonstrates how to execute a Java program using BPXBATCH, specifying a preloaded 64-bit JVMTI agent. It assumes a default installation path and a single Application Performance Analyzer started task.

```jcl
//STEP EXEC PGM=BPXBATCH,
//PARM='sh java –agentpath:/usr/lpp/apa/v14r2/libCAZJTA14.so prog’
```
