batchtsocmd 0.2.1

Run TSO and Db2 commands via IKJEFT1B

batchtsocmd

Run TSO and Db2 commands via IKJEFT1B with automatic encoding conversion.

Description

batchtsocmd is a Python utility for z/OS that executes TSO and Db2 commands through IKJEFT1B with automatic ASCII/EBCDIC encoding conversion. It handles SYSIN and SYSTSIN inputs from files or strings, automatically converting them to EBCDIC as needed.

The package provides five installed commands:

Command	Program	Purpose
batchtsocmd	IKJEFT1B	General TSO command execution (raw SYSTSIN + SYSIN)
db2sql	DSNTEP2	Execute SQL statements (DDL, DML, DQL, GRANT)
db2bind	DSN BIND subcommand	Bind Db2 packages and plans
db2run	DSN RUN PROGRAM	Run a Db2-bound program
db2op	DSNTIAD	Execute Db2 operator commands (-DISPLAY, -START, -STOP)

Deprecated: db2cmd and db2admin are retained as backward-compatible aliases for db2sql and db2op respectively. New code should use the new command names.

Features

• Execute TSO commands via IKJEFT1B
• Execute Db2 SQL (DDL, DML, DQL, GRANT/REVOKE) via DSNTEP2
• Bind Db2 packages and plans via DSN BIND subcommands
• Run Db2-bound programs via DSN RUN PROGRAM
• Execute Db2 operator commands via DSNTIAD
• Automatic ASCII to EBCDIC conversion for input files
• Optional STEPLIB support with colon-separated concatenation
• Optional DBRMLIB support with colon-separated concatenation
• Configurable output destinations (SYSTSPRT, SYSPRINT)
• Environment variable support for Db2 connection parameters
• Stdin piping support
• Verbose mode for debugging

Requirements

• Python 3.8 or higher
• z/OS operating system
• IBM Z Open Automation Utilities (ZOAU)
• zoautil-py package
• zos-ccsid-converter package

Usage

batchtsocmd — General TSO Command Execution

Low-level interface: provide your own SYSTSIN and SYSIN files.

batchtsocmd --systsin systsin.txt --sysin input.txt

# With output files
batchtsocmd --systsin systsin.txt --sysin input.txt \
            --systsprt output.txt --sysprint print.txt

# With STEPLIB and DBRMLIB
batchtsocmd --systsin systsin.txt --sysin input.txt \
            --steplib DB2V13.SDSNLOAD:DB2V13.SDSNLOD2 \
            --dbrmlib DB2V13.DBRMLIB

Options:

• --systsin PATH — Path to SYSTSIN input file (required)
• --sysin PATH — Path to SYSIN input file (required)
• --systsprt PATH — SYSTSPRT output file or stdout (default: stdout)
• --sysprint PATH — SYSPRINT output file or stdout (default: stdout)
• --steplib DATASET — STEPLIB dataset(s), colon-separated
• --dbrmlib DATASET — DBRMLIB dataset(s), colon-separated

---

db2sql — Execute SQL Statements

Executes SQL statements (DDL, DML, DQL, GRANT, REVOKE, SET CURRENT SQLID) via DSNTEP2. Replaces the former db2cmd command.

# Inline SQL
db2sql "SELECT * FROM SYSIBM.SYSTABLES WHERE NAME = 'ACCOUNT'"

# From a file
db2sql --file schema.sql

# From stdin
echo "DROP TABLE IBMUSER.ACCOUNT;" | db2sql

# Create schema
db2sql --file instdb2.sql --system DB2P --plan DSNTEP12 \
    --toollib DSNC10.DBCG.RUNLIB.LOAD \
    --steplib DB2V13.SDSNEXIT:DB2V13.SDSNLOAD

# GRANT via inline SQL (SET CURRENT SQLID sets the owning auth ID)
db2sql "SET CURRENT SQLID = 'IBMUSER'; \
        GRANT EXECUTE ON PLAN CBSA TO CICSUSER; \
        GRANT SELECT, INSERT, UPDATE, DELETE ON TABLE IBMUSER.ACCOUNT TO CICSUSER;"

# With environment variables set
db2sql --file grants.sql

Options:

• SQL — Inline SQL statement(s) (positional, optional)
• --file PATH / -f PATH — SQL input file (mutually exclusive with inline SQL and stdin)
• --system ID — Db2 subsystem ID (or DB2_SYSTEM)
• --plan NAME — Plan name for DSNTEP2 (or DB2_PLAN)
• --toollib LIB — Tool library (or DB2_TOOLLIB)
• --steplib DATASET — STEPLIB dataset(s), colon-separated (or DB2_STEPLIB)
• --dbrmlib DATASET — DBRMLIB dataset(s), colon-separated (or DB2_DBRMLIB)
• --systsprt PATH — SYSTSPRT output file or stdout (default: stdout)
• --sysprint PATH — SYSPRINT output file or stdout (default: stdout)
• -v, --verbose — Enable verbose output

Notes:

• Multiple SQL statements must be separated by semicolons
• SQL lines are automatically padded to 80 bytes
• GRANT is plain SQL and runs through DSNTEP2 — no special program needed
• Use SET CURRENT SQLID before GRANTs to set the owning authorization ID

---

db2bind — Bind Db2 Packages and Plans

Generates and executes DSN BIND PACKAGE and/or BIND PLAN subcommands via IKJEFT1B. No SQL input is used — all parameters are on the BIND subcommands in SYSTSIN.

Key Features

• Dual Binding Modes:
  • Dataset-based binding using --dbrmlib (traditional approach)
  • Filesystem-based binding using --library (new feature)
• Automatic Extension Handling: Automatically strips .dbrm extension from member names when present
• Environment Variable Support: Both DB2_DBRMLIB and DB2_LIBRARY can be set as defaults
• Mutual Exclusivity: Enforces that only one binding mode is used per invocation

Dataset-Based Binding

Traditional binding using DBRM datasets:

# Bind a single package
db2bind --system DB2P --package PCBSA --member CREACC \
    --dbrmlib CBSA.CICSBSA.DBRM \
    --steplib DB2V13.SDSNEXIT:DB2V13.SDSNLOAD

# Bind multiple packages with owner and qualifier
db2bind --system DB2P --package PCBSA \
    --member CREACC --member CRECUST --member DELACC \
    --owner IBMUSER --qualifier IBMUSER --action REPLACE \
    --dbrmlib CBSA.CICSBSA.DBRM \
    --steplib DB2V13.SDSNEXIT:DB2V13.SDSNLOAD

# Bind a plan with package list
db2bind --system DB2P --plan CBSA --owner IBMUSER \
    --isolation UR --pklist "NULLID.*" --pklist "PCBSA.*" \
    --steplib DB2V13.SDSNLOAD

# Bind packages and plan together (equivalent to DB2BIND.jcl)
db2bind --system DB2P \
    --package PCBSA --owner IBMUSER --qualifier IBMUSER \
    --member CREACC --member CRECUST --member DBCRFUN \
    --member DELACC --member DELCUS --member INQACC \
    --member INQACCCU --member BANKDATA --member UPDACC --member XFRFUN \
    --plan CBSA --isolation UR \
    --pklist "NULLID.*" --pklist "PCBSA.*" \
    --dbrmlib CBSA.CICSBSA.DBRM \
    --steplib DB2V13.SDSNEXIT:DB2V13.SDSNLOAD

Filesystem-Based Binding

Bind packages using DBRM files from a USS filesystem directory:

# Bind a single package from filesystem
db2bind --system DB2P --package PCBSA --member CREACC \
    --library /u/fultonm/projects/cbsa/etc/build/obj \
    --owner FULTONM --qualifier FULTONM --action REPLACE \
    --steplib DB2V13.SDSNLOAD

# Using environment variable
export DB2_LIBRARY=/u/fultonm/projects/cbsa/etc/build/obj
db2bind --system DB2P --package PCBSA --member CREACC \
    --owner FULTONM --qualifier FULTONM

# Bind multiple members from filesystem
db2bind --system DB2P --package PCBSA \
    --member CREACC --member CRECUST --member DBCRFUN \
    --library /u/fultonm/projects/cbsa/etc/build/obj \
    --owner FULTONM --qualifier FULTONM

# Member names with .dbrm extension are automatically handled
db2bind --system DB2P --package PCBSA \
    --member CREACC.dbrm --member CRECUST.dbrm \
    --library /u/fultonm/projects/cbsa/etc/build/obj \
    --owner FULTONM --qualifier FULTONM

Options:

• --system ID — Db2 subsystem ID (or DB2_SYSTEM) (required)
• --package NAME — Package collection name for BIND PACKAGE (e.g. PCBSA)
• --plan NAME — Plan name for BIND PLAN (e.g. CBSA)
• --member NAME — DBRM member to bind as a package (repeatable). Extension .dbrm is automatically stripped if present.
• --owner ID — OWNER for BIND subcommands
• --qualifier ID — QUALIFIER for BIND subcommands
• --action ADD|REPLACE — BIND action (default: REPLACE)
• --isolation UR|CS|RS|RR — Isolation level for BIND PLAN
• --pklist ENTRY — Package list entry for BIND PLAN PKLIST (repeatable)
• --dbrmlib DATASET — DBRMLIB dataset(s), colon-separated (or DB2_DBRMLIB). Mutually exclusive with --library.
• --library PATH — USS filesystem directory containing DBRM files (or DB2_LIBRARY). Mutually exclusive with --dbrmlib.
• --steplib DATASET — STEPLIB dataset(s), colon-separated (or DB2_STEPLIB)
• --systsprt PATH — SYSTSPRT output file or stdout (default: stdout)
• --sysprint PATH — SYSPRINT output file or stdout (default: stdout)
• -v, --verbose — Enable verbose output

Notes:

• At least one of --package or --plan must be specified
• --member is required when --package is specified
• The --library and --dbrmlib parameters are mutually exclusive. Use --library for filesystem-based binding or --dbrmlib for dataset-based binding, but not both.
• When using --library, DBRM files are read from the USS filesystem directory and allocated to a temporary dataset for binding
• BIND subcommands are DSN processor commands, not SQL — DSNTEP2 is not used
• RC 0 = success, RC 4 = warnings (acceptable for bind operations)

db2run — Run a Db2-Bound Program

Executes an arbitrary Db2-bound program via DSN RUN PROGRAM via IKJEFT1B. Equivalent to the BANKDATA.jcl pattern.

# Run BANKDATA to generate test data (equivalent to BANKDATA.jcl)
db2run --program BANKDATA --system DB2P --plan CBSA \
    --toollib CBSA.CICSBSA.LOADLIB \
    --parm '1,10000,1,1000000000000000' \
    --steplib CBSA.CICSBSA.DBRM:CBSA.CICSBSA.LOADLIB:DB2V13.SDSNLOAD

# Run a custom Db2-bound utility
db2run --program MYUTIL --system DB2P --plan MYPLAN \
    --toollib MY.LOADLIB

Options:

• --program NAME — Name of the Db2-bound program to run (required)
• --system ID — Db2 subsystem ID (or DB2_SYSTEM) (required)

Notes:

• No SYSIN SQL input is used — all parameters are on the RUN PROGRAM subcommand
• The program must be bound to Db2 with the specified plan

---

db2op — Execute Db2 Operator Commands

Executes Db2 operator commands (-DISPLAY, -START, -STOP, etc.) via DSNTIAD. Replaces the former db2admin command.

# Inline operator command (leading '-' is optional)
db2op "-DISPLAY DATABASE(*)"
db2op "DISPLAY DATABASE(CBSA) SPACENAM(*) USE"

# From a file
db2op --file opcmds.txt

# From stdin
echo "-STOP DATABASE(CBSA) MODE(QUIESCE)" | db2op

# With explicit connection parameters
db2op "-DISPLAY THREAD(*)" --system DB2P --plan DSNTIAD \
    --toollib DSNC10.DBCG.RUNLIB.LOAD

Options:

• COMMAND — Inline operator command (positional, optional). Leading - is optional.
• --file PATH / -f PATH — File containing operator commands (mutually exclusive with inline and stdin)

• -v, --verbose — Enable verbose output

Notes:

• The leading - prefix on operator commands is optional and added automatically if missing
• Uses DSNTIAD, not DSNTEP2 — operator commands are not SQL

---

How It Works

All Db2 commands follow the same execution pipeline:

1. SYSTSIN generation — Each function generates the appropriate DSN subcommands in SYSTSIN:

   • db2sql: DSN SYSTEM(...) → RUN PROGRAM(DSNTEP2) PLAN(...) LIB(...) PARMS('/ALIGN(MID)')
   • db2bind: DSN SYSTEM(...) → BIND PACKAGE(...) / BIND PLAN(...) subcommands
   • db2run: DSN SYSTEM(...) → RUN PROGRAM(...) PLAN(...) LIB(...)
   • db2op: DSN SYSTEM(...) → RUN PROGRAM(DSNTIAD) PLAN(...) LIB(...)

2. Encoding conversion — Input files are auto-detected and converted from ASCII to EBCDIC (IBM-1047) as needed using zos-ccsid-converter

3. SYSIN padding — SQL input lines are padded to exactly 80 bytes for fixed-length MVS record format

4. Execution — mvscmd.execute_authorized() from ZOAU runs IKJEFT1B with the generated DD statements

5. Output — SYSTSPRT and SYSPRINT are written to files or stdout; output files are tagged IBM-1047

6. Cleanup — All temporary files are removed automatically
