Issue/Introduction

How can I search IDMS  CV memory to check where a string is loaded?

For example, we can check and search a string in a program in memory by doing LOOK program=pgmname

I would like to search a string for all programs loaded in the memory, if possible could be using batch job or online.

 

Environment

Release : 19.0

Resolution

To display a list of all loaded programs use the DCMT DISPLAY ACTIVE PROGRAMS command.
There are 4 commands for the 4 program pools

DCMT DISPLAY ACTIVE PROGRAMS
DCMT DISPLAY ACTIVE XA PROGRAMS
DCMT DISPLAY ACTIVE REENTRANT PROGRAMS
DCMT DISPLAY ACTIVE XA REENTRANT PROGRAMS

To search for a specific string in memory use the DCMT DISPLAY MEMORY command 
The syntax is 
DCMT D MEM STR C'cccccc'   search-options
or 
DCMT D MEM STR x'nnnnnn'   search-options

The search-options are:

►►──┬──────────────────────┬─┬──────────────┬─────────────────────────►
    ├─ (1) ◄───────────────┤ ├─ 16 ◄────────┤
    └─ (occurrence-count) ─┘ └─ byte-count ─┘

 ►──┬─ Addr hex-address search-length ─┬──────────────────────────────►◄
    ├─ Lte logical-terminal-id ────────┤
    └─ Taskid task-id ─────────────────┘
 
 
If you do not specify a search domain (that is, ADDR, LTE, or TASKID) on the STR search string option, it will search the whole region so it may take a while to execute.
If you are planning to do this in production you should specify a search domain to limit the search to a specific address range.
