Hello,

I believe you need to talk with someone from "onsite".

Hi,

I've two definitions of RTT, what are You looking for..

(1). Real-Time Trace: A system utility that counts or traces the use of specific macros and related system activity when activated by functional messages issued from CRAS terminals.

(2) Resource Translation Table (DB2).

Hi,

Unfortunately I don't speak IMS to DB2 maaping, little information I've from one documantation available to me..

Quote:
The resource translation table (RTT) maps IMS application control block names to DB2 for z/OS plan names. When an IMS transaction accesses DB2 for z/OS, the plan name used is, by default, the IMS application control block name. The control block name is the same as the PSB name that is specified in the APPLCTN macro.

The RTT is assembled in a CSECT with the name that is the same as the label of the first macro in the table. This CSECT must then be placed in an APF authorized library in the IMS.SDFSRESL concatenation of the IMS control region. The RTT is pointed to in the PROCLIB member that defines the DB2 attachment. If the RTT parameter is null, the RTT is not used.

It is possible to set up an RTT that translates an IMS application control block name to a different DB2 plan name. Setting up such a table is described in the DB2 for z/OS (not IMS) documentation.

The reassembled table is picked up the next time IMS is stopped or started or after a stop (/STO SUBSYS xxxx) and restart (/STA SUBSYS xxxx) of the DB2 connection.

Thank you very much Anuj...

I have some thing to add to this,

"We need to define any Program/Transaction which calls a DB2 table in the RTT table (in all profiles and environments). The RTT provides the optimum path to take data from DB2 table, by defining the Main driver program/transaction. Resource translation table (RTT), maps the IMS application names into DB2 plan names. If this entry is omitted, the DB2 plan name is the IMS application load module name. "

Thanks once again for your fast response.

Regards,
