Issue/Introduction

When the Endevor files are managed with the L-Serv fileserver and also using the IBM RDz/Carma with Endevor, it is recommended to review the parameter submitted with LServ command ADDPOOL.

Environment

z/OS
Release : All
Component : Endevor, L-Serv

Cause

In some case, the STRNO parameter in the L-Serv LSR buffer pool might need to be increased when IBM Rational Developer RDz is in use, and L-Serv is used to manage the Endevor MCF's.

Resolution

Using IBM Rational Developer RDz and Carma with Endevor may require some adjustment of the LSR buffer pool.

When the L-Serv buffer POOL are allocated using the command ADDPOOL, it may be necessary to increase the STRNO(VSAM placeholders allocated for the file).

The default value is 32 but it is likely that this value is too small when using RDz/Carma, due to inventory sweeps.

Symptom is hangs of the TSO/Endevor sessions.

In that case,  the STRNO value on the ADDPOOL statements to which MCF's map must be increased, for example:
   'ADDPOOL 01 (2048,199) (8192,299) STRNO(255)'
