Re: IEASYMxx: How is possible define more than one LPARNAME at same time in SYSDEF?
The short answer is that what you want to do is very possible. We've been running with similar configurations for many years through various hardware combinations and LPAR distribution. Our specific IEASYMxx members would probably not fit your particular needs and are overly complicated anyway. I can offer a few suggestions. 1. In addition to SYM, you also want two LOADxx members. When we IPL in 'normal' mode, we use LOAD00. When we IPL in DR mode, we use LOADDR. The choice is determined by the load parm value in the IPL profile: '00' for normal profile, 'DR' for DR mode profile. That suffix is appended to 'LOAD' to select the appropriate member in the IPLPARM library. 2. The primary difference between LOAD00 and LOADDR is the concatenation list for IEASYMxx. Within each concatenation, system symbols are set according to the environment being IPLed. This accounts for, among other values, different CTC addresses, gazinta and gazouta, among LPARs in normal vs. DR configuration. 3. IEASYMxx contains statements like these, which are specified for each hardware-LPAR combination, normal or DR mode SYSDEF HWNAME(box-1) LPARNAME(LPAR-1) /* FOR THIS LPAR-PROCESSOR */ SYSNAME(sysname-1)/* USE THIS SYSNAME */ SYMDEF(CTCPID#1='i-xxx,i-yyy') /* SET INPUT ADDRESS LIST */ SYMDEF(CTCPOD#1='o-xxx,o-yyy') /* SET OUTPUT ADDRESS LIST */ 4. Here are some sample statements from COUPLExx. COUPLE SYSPLEX(SYSPLEXOURPLXID) /* Symbol set in IEASYSxx */ PCOUPLE(SYS1.COUPLE.SYSPLEX1) ACOUPLE(SYS1.COUPLE.SYSPLEX2) PATHIN /* BACKUP CTC FOR CF */ DEVICE(CTCPID#1,CTCPID#2,CTCPID#3) /* Symbol strings set in IEASYSxx */ PATHOUT /* BACKUP CTC FOR CF */ DEVICE(CTCPOD#1,CTCPOD#2,CTCPOD#3) /* Symbol strings set in IEASYSxx */ CLASS(DEFSMALL) You're on the right track. You should be able to completely initialize either environment by changing only the HMC load parm, which really means choosing--by name--between a 'normal' profile and the corresponding 'DR' profile. If you have not done so, install the SYSPARM dialog from SYS1.SAMPLIB(SPPINST). It is immensely helpful in testing system symbol settings. . . .

Q.3) Then. How could define in the same configuration of the IEASYM member to before and after of the FDR movement..? It is important to mention that the channel addresses for CTC are different in a z196-1 with respect to the channel addresses for CTC in the other z196-2 (different building). There are not have a specific IEASYSxx and IEASYMxx settings for FDR because we only use two LOADxx members where they have defined in the IODF the Partitions directly with a matrix for the CHPIDs for one Building (z196-1) and other different matrix (also with different CHPIDs) for the other Building (z196-2). Q.4) Please, someone have any idea about it..? No matter how complex can become the definition of IEASYMxx if with that definition a solution is found. Honestly, I'm confused because I do not find a way to merge two partitions that always move to another machine, with a partition (TEST1) that never moves from that machine (z196-1) and vice versa (TEST2 never moves from z196-2). Any ideas are welcome. Best regards. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

Crossposted. I had posted this on the JES2 list but got no insight so far. Hopefully someone here can shed some light on this. I stumbled across a job that had ended and was in status HELD in the JES2 execution queue. First I thought someone must have issued a $HJnnn while the job was running. I then saw that the job has had some problems (878-10 abends) which finally lead the job and the initiator being terminated at end of memory (initiated by DB2 - step ends with S0F4 reason F30905).

Re: $HASP311 jobname re-queued at end of memory and held
So APAR OA21984 states you would need JOURNAL=YES on JOB. Without complete understanding of your JES2 INIT Deck, you initiators, I am not sure if we can answer that question. You might open an SR with IBM to get in-depth knowledge for your question. I am not sure that IBM provided full disclosure on this condition. To me the message indicates that you had a job that ran into an end of memory condition that did not allow JES2 to complete it. So JES2 placed it in the HELD queue based on your JES2 environment. Might try the JES2 INIT and TUNING Guide/Reference on the parms related to restart, like Journal.
