SAP Java Server Node Not Starting


If the java server node is not starting up check the bootstrap properties. If you see the following, set the environment variable LDR_CNTRL to USERREGS.

JVMCI200 - ERROR: User register saving is not enabled, Garbage Collection could be incorrect.
JVMCI200 - ERROR: because of this the JVM library is explicitly aborting the process
JVMCI200 - ERROR: You must either rebuild the executable using "-bM:UR"
JVMCI200 - ERROR: or run with "export LDR_CNTRL=USERREGS"

You can set the environment variable using the command 'export LDR_CNTRL=USERREGS' or 'setenv  LDR_CNTRL USERREGS' in UNIX depending on the shell used.
USERREGS enables user register saving when system calls are made by the JVM.

SAP Memory Parameters Tuning - Part 1

Image
Roll and Extended Memory ztta/roll_first - This is the first area of memory assigned to a work process. This parameter is usually set to 1 as a technically necessity as the modern applications will end up using more memory than the first roll segment. Even if ztta/roll_first is set to 1, the minimum amount required for administrative data is allocated from roll memory. It is best to leave the parameter at 1. ztta/roll_extension - Further memory allocation to the work process is done from Extended Memory, after first roll segment is used up. ztta/roll_extension parameter determines how much memory can be used by a user context in the extended memory. In other words, this is the limit of the SAP Extended Memory for each work process. This is true in most cases, however, ztta/roll_extension is Extended Memory limit for a single "i-mode". Depending on the number of i-modes, normally up to 6, the value of maximum extended memory can raise up to 6*ztta/roll_extension theoret...

OS/DB Migration - CMD. STR, TOC, EXT, R3load, DDLDBS.TPL and more

Image
With increasing need to improve performance or reduce costs or vanishing support for operating systems/databases it becomes inevitable to migrate to a better OS or DB. We feel take a quick look at the primary ingredients of the tools for OS/DB migration handled by R3SETUP. Tools - R3load, R3ldctl and R3szchk R3ldctl creates STRucture files, TemPLate files by reading the technical settings for table/indexes in SAP data dictionary. R3szchk calculates the database size object sizes (EXTent files) for the target system based on the STR files created by R3ldctl. The EXT and STR files can be later split into smaller groups. The most crucial tool R3load is responsible for unloading and loading data from the database. R3load uses the files created by R3ldctl and R3szchk and dumps the data into compressed binary format as .001, .002 .. files. It uses cmd files to achieve the task. If the cmd files are not present, it creates on its own. Files Command files*.cmd  are creat...

Fixing Inconsistent Table - Table activation fails due to inconsistency between DD and DB

If you find a table to be available on the database, but not active in ABAP dictionary, try calling SE14 as DDIC user, enter the table name and choose Table > Reconstruct, Execute. If this method fails follow these steps: Call transaction code SE37 and execute the function module  DD_TABL_ACTM with single test On the next screen, do not change any other field except the following and set them as shown below: MODE: 12 NTAB_PUTSTATE: N TABNAME: <enter the correct table name> Click on Execute The export parameter ACT_RESULT should show 0. To verify if the inconsistency is fixed, call transaction SE14 > Extras > Database Object > Check and  SE14 > Extras > Runtime object > Check.
