Name

ex_env — Enduro/X Environment configuration

DESCRIPTION

Enduro/X use set of environment variables which is initial environment for application domain. There is set of parameters related to system, prefixes, Posix Queue mount points, various system limits. Next step to the configuration is application domain configuration by it self, in ndrxconfig.xml and debug.conf (or Common-Configuration respectively).

Mandatory Env. Variables

NDRX_NODEID=NODE_ID
Cluster Node ID. Should be within 1..32.
NDRX_CLUSTERISED=1|0
Do we work in cluster mode or not? 1 - yes, we are in cluster. 0 - no, we are not in cluster.
NDRX_LDBAL=LOAD_BALANCE_PERCENT
if LOAD_BALANCE_PERCENT is 0 = means process all locally, if value is set to 100 = process all on remote servers (if svc available on remote server). 70% means, process 30% locally 70% remotely.
NDRX_TOUT=TIME_OUT_IN_SECONDS
Global tpcall() timeout, if not called with TPNOTIME flag. If process will not return in this time, then TPETIME error will be returned.
NDRX_ULOG=ULOG_PATH
Writable system path where to write user logs.
NDRX_QPREFIX=APP_PREFIX
Prefix used for POSIX IPC resources (shm and queue).
NDRX_SVCMAX=MAX_SERVICES
This determines the maximum number of services supported by instance. The less is number, then less shared memory is used. However for performance reason, number should be much bigger (3-4 times) than actual estimated service count. Bigger number might speed up linear hashing, i.e. it will be less likely that hash will collide.
NDRX_SRVMAX=MAX_SERVERS
Maximum number of servers that will be supported. This affects the -i flag. Server ID. The max server id will be MAX_SERVERS-1.
NDRX_CONFIG=FULL_PATH_TO_CONFIG_FILE
This shows the full path to usual ndrxconfig.xml.
NDRX_QPATH=QUEUE_MOUNT_POINT
Full path to directory where POSIX Queue is mounted.
NDRX_SHMPATH=SHARED_MEM_MOUNT_POINT
Full path to POSIX Shared memory mount point.
NDRX_CMDWAIT=NDRXD_COMMAND_WAIT_SECS
Number of second to wait for commands, after which ndrxd does other checks.
NDRX_DPID=PATH_TO_NDRXD_PID_FILE
This is full path to ndrxd PID file.
NDRX_RNDK=APP_DOMAIN_RANDOM_KEY
Random key to indentify the processes beloning to this app domain (i.e. used in ps ef).
NDRX_IPCKEY=SYS_V_SEMAPHORE_KEY
System V Semaphores key number. Used for shared memory locking. POSIX semaphores are not used here, because they are not unlocked if process dies during acquired semaphore. For System V shared memory IPCKEY+0..5 different keys may be used for shared memory. For System V semaphores IPCKEY+0..2 range is used.
NDRX_MSGMAX=MAX_MSGS_PER_QUEUE
Posix queue config attrib. Max number of messages that can be put in one queue.
NDRX_DQMAX=NDRXD_ACCESS_Q_MSG_MAX
Enduro/X ATMI daemoni ndrxd access Q size. Bigger is better.
NDRX_MSGSIZEMAX=NDRXD_ACCESS_Q_MSG_MAX
Max message size (in bytes). The value is limited to the operating system limits of the maximums size of the POSIX queues message size. For example on Linux kernel 3.13 it is possible to set message size to 10 Megabytes. Also the message size denotes the internal buffer sizes for XATMI message processing. If message size max is set to less than 64KB, then buffer size is defaulted to 64KB. This parameter also affects the opening/creation of the message queue. As the message size is specified in mq_open() attributes.
NDRX_APPHOME=FULL_PATH_TO_APPDOMAIN_INSTANCE_DIR
This is full path to application (not an Enduro/X directory it self) root directory.
NDRX_HOME=FULL_PATH_TO_ENDUROX_ROOT_DIRECTORY
Full path to Enduro/X installaction directory.
NDRX_DEBUG_CONF=FULL_PATH_TO_DEBUG_CONFIG_FILE
This sets full path to debug configuration file.
NDRX_UBFMAXFLDS=MAX_NUMBER_OF_UBFFIELDS
Max number of UBF fields. Used for hashing. Bigger number is better. The max number is number is 33554432 (25 bit).
NDRX_DMNLOG=FULL_PATH_TO_NDRX_DMNLOG
The full path to ndrxd log file. Used by shell scripts.
NDRX_DMNLEV=LOG_LEVEL_OF_NDRXD
Log level of ndrxd. From 1..5. 5 is max. Used by shell scripts.
NDRX_LOG=FULL_PATH_TO_XADMIN_LOG_FILE
Full path to xadmin log file. Used by shell scripts.
NDRX_LEV=LOG_LEVEL_OF_XADMIN
Log level of xadmin. From 1..5. 5 is max. Used by shell scripts.
NDRX_XA_RES_ID=XA_RESOURCE_ID
XA API two phase commit resource id. Must be set if using distributed transactions. Valid value is in range of 1..255.
NDRX_XA_OPEN_STR=XA_OPEN_STRING
This is open string for two phase commit XA driver. Must be set if using distributed transactions.
NDRX_XA_CLOSE_STR=XA_CLOSE_STRING
This is close string for two phase commit XA driver. This is optional, NDRX_XA_OPEN_STR will be used if not set.
NDRX_XA_DRIVERLIB=ENDUROX_XA_DRIVER_LIB
This is full path to Enduro/X shared library which loads the XA api.
NDRX_XA_RMLIB=RESOURCE_MANAGER_SPECIFIC_DRIVER
This is full path to resource manager’s specific driver (shared library). Must be set if using distributed transactions.
NDRX_XA_LAZY_INIT=LAZY_INIT_FLAG
Set to 1 if XA sub-system should be initialized on first transactions. If not set, then defaulted to 0, meaning initialize XA sub-system on executable startup.
NDRX_XA_FLAGS=XADMIN_XA_FLAGS
Special for XA sub-system. It is semicolon separated tags with values. currently tags RECON, NOJOIN and NOSTARTXID are defined. RECON tag defines the number of attempts of xa_close()/xa_open() and doing xa_start() again in case if original xa_start() failed (the ATMI call tpbegin()) - for example firewall have been closed the connection. The format for the tag is: RECON:<comma separated list of error codes e.g. 4,-8,* - any err>:<number of attempts>:<sleep between attempts milli-sec>[:<non_start_error codes for retry>]' example: RECON:*:3:100, meaning reconnect (do xa_close()/xa_open()) on any xa_start error, do the 3x attempts, sleep 100 milliseconds between attempts. Flag RECON for other XA calls that xa_start() would also perform reconnects, but that would be applied to XAER_RMFAIL errors only by default. To change the list of error codes for xa_prepare, xa_commit, xa_rollback, xa_recover, xa_forget retries, set the comma seperated list of codes in non_start_error position. With NOJOIN indicates that XA Switch does not support TMJOIN mode. With NOSTARTXID indicates that transaction session does not start with identifier, but only when process disconnects from transaction, it is possible to give transaction id for work which has been done to database. NOSUSPEND flag can be used to configure particular resource that transaction is not suspended when tpcall(3) is issued from process which uses given resource manager. BTIGHT flag together with NOJOIN flag ensures that tight branching is used. By default Enduro/X writes branch id in gtrid and bqual parts equally. With BTIGHT flag set, gtrid is not changed for particular RMID, but only branch qualifier bqual will be updated to contain the actual branch identifer. Flag FSYNC ensures that tmsrv(8) log contents at commit decision are written to disk with fsync(). FDATASYNC ensures that tmsrv(8) commit decision is written to disk with fdatasync(). DSYNC ensures that tmsrv commit decision log file is synchronized with file-system directory structure (i.e. fsync() is performed on log file directory). In case if using tmqueue(8) then these flags also affect that the way how messages are persisted to disk. Note that FSYNC, FDATASYNC and DSYNC may significantly slow down the distributed transaction processing.
NDRX_NRSEMS=NDRX_NRSEMS
Number of semaphores used for protecting shared memory, when Enduro/X running in poll() mode. The minimum is recommended something about 7. Every service name in shared memory is hashed and semaphore protecting the service is calculated by modulus of NRSEMS. This affects NDRX_IPCKEY semaphore, by giving the more occurrences in array. The first array entry is used by normal Enduro/X operations, and the others 2..1+NRSEMS is used by poll() mode service protection. Default value is 30.
NDRX_MAXSVCSRVS=NDRX_MAXSVCSRVS
Max number of servers can advertise same service. This is used only in poll() and SystemV mode. The number affects the size of shared memory used for services. Bigger number causes more memory to be used for service registry. If the number of servers goes over this number for one service, the service entry will be ignored. Default is 30.
PATH=PATH
This is not Enduro/X specific env variable. But Enduro/X distribution bin directory should be included in system PATH env. variable.
FLDTBLDIR=FULL_OR_RELATIVE_PATH_OF_UBF_FIELD_DIRS
This is colon separated list of directories where .fd files are located. I.e. UBF field definitions.
FIELDTBLS=COMMA_SEPERATED_LIST_OF_FIELD_FILES
This is comma separated list of field files found in FLDTBLDIR.
NDRX_CCONFIG=NDRX_COMMON_CONFIG_FILE
If this is set then, all above configuration is read from specified ini file in NDRX_COMMON_CONFIG_FILE in [@global] section. The Enduro/X config driving unit is able to merge configuration from multiple config files, and you can set higher priority files by in NDRX_CCONFIG1, NDRX_CCONFIG2 NDRX_CCONFIG3, NDRX_CCONFIG4, NDRX_CCONFIG5. Basically NDRX_CCONFIG is lowest priority and NDRX_CCONFIG5 is highest priority. The specified configuration file can be directory, in that case Enduro/X will search for files with mask *.ini, *.cfg, *.conf, *.config files. All will be loaded in alphabetical order.
NDRX_CCTAG=NDRX_COMMON_CONFIG_TAG
This is basically subsection used for Enduro/X configuration sections [@global], [@debug], [@queue]. If the variable is set, then Enduro/X will lookup at process startup for sections like [@global/YOUR_TAG], etc. CC tag can contain multiple sections, for example server1/RM2. Enduro/X will lookup the variables in each section [@global/server1] and [@global/RM2] for setting up the system.
NDRX_XADMIN_CONFIG=XADMIN_CONFIG_FILE
This variable is used by xadmin read the specific configuration file with xadmin’s settings. Variable is optional.
HOME=UNIX_USER_HOME_DIR
This variable is used by xadmin to search for per user configuration file when xadmin is started. In home directory search for configuration is done by $HOME/.xadmin.config. This file is used in case if NDRX_XADMIN_CONFIG is missing. Variable is optional.
VIEWDIR=NDRX_VIEW_DIR
This is colon separated list of directories where to search VIEW compiled object files. The access to these directories are done only once operations with views are performed.
VIEWFILES=NDRX_VIEW_FILES
Comma separated list of VIEW object files (typically with extension .V). Object files are produced by view compiler viewc(8).
NDRX_PLUGINS=NDRX_PLUGINS
This is semicolon separated string which denotes the list Enduro/X plugins which needs to be loaded at any XATMI program startup. Following plugins are provided with Enduro/X: libcryptohost.so - cryptography key by hostname.
NDRX_SILENT=SILENT_SETTING
If environment variable is present (and set to Y), the xadmin tool will not print banner header at startup.
NDRX_XADMINTOUT=XADMIN_TOUT
This override of NDRX_TOUT configuration for xadmin queue operations. This timeout is used for certain calls to ndrxd (for example startup, shutdown, service listing, etc). Also it is used for communication with XATMI servers like cpmsrv and tmsrv. This is number of seconds, the value must be greater than 0. If parameter is set, then this will enable timeout control for communication with ndrxd daemon, if parameter is not set, the code will work in legacy mode, meaning that list calls to ndrxd will never get timeout.
NDRX_SVPROCNAME=SERVER_PROC_NAME
Server process name exported by ndrxd at XATMI server process boot time. The name is server name extracted from "<server>" tag attribute name.
NDRX_SVCLOPT=SERVER_COMMAND_LINE
Server process command line. Generated and exported at the moment of XATMI server boot. If no command line options are passed to XATMI server, then libatmisrv tries to extract the parameter from this environment variable before failing, due to missing command line arguments.
NDRX_SVPPID=SERVER_PARENT_PID
Parent process PID of server process. This process basically is the one which is booted by ndrxd. In case if server definition contains some wrapper processes (or scripts), then this basically is different than value of the real XATMI server. This variable is used by XATMI server library to report both PIDs to the ndrxd, the parent PID and the real process PID.
NDRX_SVSRVID=SERVER_PROCESS_ID
This is XATMI server id set in <srvid> tag. The variable can be used for example is wrapper scripts to modify some resources used by process. For example if booting something like Tomcat app server, the admin TCP ports can be adjusted by this environment variable in order to avoid conflicts for booting multiple instances.
NDRX_SVQREADERSMAX=MAX_SIMULTANEOUS_READERS
This configuration parameter set the maximum parallel readers for System V to Posix queues mapping tables. The number is used for read-write locks, thus the number sets the simultaneous readers, but during that time the write thread needs to wait for all readers to finish up the mapping when the writer will step in and all readers will wait. If the number is bigger read will be performed better when many processes are used, but that could lead to write starvation, and writes (opening queues) may become slow. System V queues acquires one more semaphore resource from the NDRX_IPCKEY+1. Thus this semaphore is used read/write mode to protect the SystemV-to-Posix and Posix-to-SystemV mapping tables. The default value for this parameter is 50. This parameters is also used when processes accesses services shared memory in System-V or EMQ mode for protecting the round-robin selector.
NDRX_MSGQUEUESMAX=MAX_IPC_QUEUES
Max number of queues that can be mapped to System V sub-system. This parameter defines size for two shared memory chunks which names are <NDRX_QPREFIX>,shm,p2s and <NDRX_QPREFIX>,shm,s2p. The number defines number of queue entries in the table. The bigger the number, the better hashing is got and lookup is quicker, but more memory is used. The minimum number shall be equal to the number of queues that will be used on the system, but recommended number is something as twice it. Each queue entry requires about 168 bytes. The default value for this parameter is 20000.
NDRX_CLTTAG=CLIENT_PROCESS_TAG
This is client process tag exported to cpmsrv(8) controlled processes. This value can be used also in ndrxconfig.xml(5) when formatting client process command line and log file names.
NDRX_CLTSUBSECT=CLIENT_PROCESS_TAG
This is client process tag’s sub-section exported to cpmsrv(8) controlled processes. This value can be used also in ndrxconfig.xml(5) when formatting client process command line and log file names.
NDRX_LIBEXT=SHARED_LIB_EXTENSION
This is shared library platform specific extension. For example Linux/AIX and Solaris would use "so". For MacOS it would be "dylib". Env variable is generated by provision script and it set in global variables.
NDRX_NORMWAITMAX=NORM_WAIT_ATTEMPTS
This configures number of attempts for xadmin(8) (and tpadmsv(8)) commands to wait in case if command requires normal ndrxd(8) context, but process is in other context, for example starting or stopping. The default is 60. Between each attempt 1 second sleep is done.
NDRX_FPAOPTS=POOL_MALLOC_OPTS
This flag allows configures Enduro/X Fast Pool Allocator. Pool Allocator is mechanism in Enduro/X core libraries to avoid calls to malloc() and free() system calls. Instead for memory block of sizes 256, 512, 1024, 2048, 4096 and S ( NDRX_MSGSIZEMAX - system buffer) are allocated and cached (stored in linked list) when parked free. Thus at certain points Enduro/X requests for memory different sizes from FPA, the FPA library finds the first suitable size (may be bigger than request) and block is removed from list. When program does free the block, FPA returns it to linked list instead of freeing back to the system. Thus from OS perspective memory is still used. For each of the block sizes maximum number stored blocks are configured. The configuration is written in following form <block_size>:<stored_count>,…,<block_size_N>:<stored_count_N>. There is also defined special block size D. This means default. By setting this values, counts are changed for all sizes. The stored count can be set in value of 1..max_int. If set to special value M, then standard, then malloc is used directly. It is error to have other non valid number as count. If block size is not found then system, the userlog message is added, but error is not generated. The block sizes supports suffix K which multiplies the value by 1024. Default value is 256:25,512:15,1K:10,2K:10,4K:10,S:10. User might adjust these buffer sizes for multi-threaded apps, especially the system buffer (S). By increasing the numbers, there is higher possibility that process will permanently use more memory.
NDRX_THREADSTACKSIZE=STACKS_SIZE_IN_KB
This is target stack size for new threads produced by Enduro/X. If value 0 is is specified, default OS new thread stack size is used. If value is not specified, then threads produced by Enduro/X are configured by stack size which is set for the program main thread (i.e. current resource limit read by getrlimit(RLIMIT_STACK, …)). If the limit is set to unlimited, then Enduro/X sets thread stack size to 8192 (which is 8 megabytes).
NDRX_SCANUNIT=SYSVTOUT_THREAD_SCAN_WAIT_MS
This flag is used by SystemV polling configuration, for others modes like epoll, poll, kqueue, emq, svapoll it is not used. The flag indicates how long time is spent (in milliseconds) on waits between scanning for System-V timeouts. The default value is 1000 and minimum is 1.
NDRX_LCFREADERSMAX=NUMBER_OF_SEM_READERS
This is number of Latent Command Framework (LCF) read/write lock readers. Thus this number of processes may process LCF commands while concurrent write (publish to LCF shared memory) will wait for readers to complete. The default is 1000. The number should match the number of processes running in system. However it depends on the commands published, if commands are fast the number could be lower.
NDRX_LCFMAX=NUMBER_OF_COMMAND_SLOTS
This is number of slots in shared memory used for LCF commands. The default is 20. Number shall be kept low as high number will make all processes to scan throughout the array of commands when any command is published. This setting shall be used as per application instance and not for sub-section configuration. Also this setting affects the configuration shared memory size (NDRX_IPCKEY + 6).
NDRX_LCFCMDEXP=NUMBER_OF_SECONDS
When new process is created, it scans and processes LCF commands at startup. This setting affects those commands for which -e is given. It sets the time frame within which after the command published it is processed. After this time command expires, and new processes does not run the command. Default value is 60.
NDRX_LCFNORUN=COMMAND_RUN_FLAG
If variable variable is present and set to y or Y, the binary still connects to LCF/Configuration shared memory, but does not execute any of the LCF commands. Default is n. This can be useful in case if xadmin(8) needs to correct some invalid commands which might prevent to run xadmin by it self.
NDRX_RTSVCMAX=SERVICE_COUNT
Number of service slots available in shared memory for <services> tag. Greater number gives better performance for linear hashing - less probability for collision. Default value is 1000.

NDRX_RTCRTMAX=CRITERION_BUFFER_SIZE: This is number of bytes available for routing criterion storage. Default value is 102400 which corresponds to 100 KB. One <route> tag takes about 300 bytes and one range entry take about 64 bytes (by not including the string data which is dynamic length).

NDRX_RTGRP=ROUTING_GROUP: This is routing group code. If environment variable is present for XATMI server process, then any service advertise and unadvertise will operate in bulk with original service name and additionally added suffix of "@<NDRX_RTGRP>". For example if having NDRX_RTGRP set to "G5" and process advertises service DEBIT, then in total two services will be advertise such as DEBIT and DEBIT@G5. Afterwards with <service/> and <route/> settings can be used to route the traffic between default service and service in group.

NOTES FOR ORACLE DB

Note that tmsrv run with multiple threads. Flag +Threads=true MUST be set in NDRX_XA_OPEN_STR. Otherwise unexpected core dumps can be received from tmsrv.

NOTES FOR IBM AIX

For IBM AIX it is recommended that NDRX_THREADSTACKSIZE parameter is used. If parameter is not set, Enduro/X tries to get new thread stack size from getrlimit(RLIMIT_STACK, …) and is assigning current value to new thread. Starting from AIX 7.2, it looks like AIX is summing these stacks and checks against the ulimit -s (which is the same RLIMIT_STACK value), and thus new threads fails to create, as total process stack limit is exhausted.
