I'm trying to turn off duplexing in a logstream because it's driving our zPDT
system to it's knees when we close an RLS file.
I've redefined the logstream:
LINE # CONTROL CARDS
1 DATA TYPE(LOGR) REPORT(YES)
2 CONTINUE
3 DEFINE LOGSTREAM NAME(MACK.LOGSTRM)
4 STRUCTNAME(MACK_GENERAL)
5 DESCRIPTION(MACK_GENERAL_LOG)
6 DASDONLY(NO)
7 WARNPRIMARY(YES)
8 DIAG(YES)
9 LS_DATACLAS(LOGR24K)
10 LS_SIZE(20480)
11 HLQ(LOGGER)
12 LOWOFFLOAD(0)
13 HIGHOFFLOAD(80)
14 STG_DATACLAS(LOGR4K)
15 STG_DUPLEX(NO)
16 LOGGERDUPLEX(COND)
17 RETPD(14)
18 AUTODELETE(YES)
Here's the IXCMIAPU report:
LOGSTREAM NAME(MACK.LOGSTRM) STRUCTNAME(MACK_GENERAL) LS_DATACLAS(LOGR24K)
LS_MGMTCLAS() LS_STORCLAS() HLQ(LOGGER) MODEL(NO) LS_SIZE(20480)
STG_MGMTCLAS() STG_STORCLAS() STG_DATACLAS(LOGR4K) STG_SIZE(0)
LOWOFFLOAD(0) HIGHOFFLOAD(80) STG_DUPLEX(NO) DUPLEXMODE() <---
RMNAME() DESCRIPTION(MACK_GENERAL_LOG) RETPD(14) AUTODELETE(YES)
OFFLOADRECALL(YES)
ZAI(NO) ZAIDATA('NO_ZAIDATA') WARNPRIMARY(YES) LS_ALLOCAHEAD(0)
DASDONLY(NO) DIAG(YES) LOGGERDUPLEX(COND) <--- EHLQ(NO_EHLQ)
GROUP(PRODUCTION)
But when I try to open a file that's defined to use MACK.LOGSTRM, it ends up
changing it back to duplex mode after generating a couple of hundred messages,
starting with these:
IXG117I DUPLEXING REBUILD STARTED FOR STRUCTURE MACK_GENERAL
1 OF 1 LOGSTREAMS CONNECTED TO STRUCTURE:
MACK.LOGSTRM
IXC571I SYSTEM-MANAGED DUPLEXING REBUILD FOR STRUCTURE
MACK_GENERAL HAS COMPLETED THE STARTUP PHASE
AND IS ENTERING THE QUIESCE PHASE.

AND IS ENTERING THE ALLOCATION PHASE.
TIME: 08/20/2020 19:23:22.380045
AUTO VERSION: D8668875 19A79A00
...and ending with:
IXG219I SYSTEM LOGGER PROCESSED TRANSITION TO DUPLEX MODE
FOR STRUCTURE MACK_GENERAL
Can someone please tell me how to disable duplexing for a logstream? And for a
structure, if that's a possible--I can't find any IXCMIAPU DEFINE STRUCTURE
parameter for DUPLEX, but when I do:
D XCF,STR,STRNAME=MACK_GENERAL
IXC360I 19.55.20 DISPLAY XCF
STRNAME: MACK_GENERAL
