Databases

Universal Spool databases are implemented as HFS or zFS data sets.

HFS Data Sets

Universal Spool List (USLIST) and Universal Spool Remove (USLRM) obtain the HFS data set names from UNVDB and UNVSPOOL ddnames.

The following table identifies the database files and the HFS data sets in which they reside.

Database Name	Data Set	File Name
Universal Broker Component Database	UNVDB	bcomponent.db
Universal Server Component Database	UNVDB	scomponent.db
Universal Server Spool Databases *	UNVSPOOL	spool.stdin.COMPID.db spool.stdout.COMPID.db spool.stderr.COMPID.db

* The COMPID in the Universal Server Spool Databases file names is the component ID assigned to the Server instance.

zFS Data Sets

zFS data sets cannot be provided via ddnames. To obtain the zFS data set names, USLIST and USLRM allocate and parse the Universal Broker's configuration member, UBRCFG00, for the /wiki/spaces/UA73/pages/3770065 and /wiki/spaces/UA73/pages/3770061 options. If these options are not found, USLIST and USLRM assume that HFS data sets are being used and refer to the UNVDB and UNVSPOOL ddnames for the HFS data set names.

Note

You can use these configuration options to specify HFS data sets as well if this method is preferred over specifying them as a ddname allocation.

USLIST and USLRM mount the HFS and zFS data sets if they are not already mounted.

The Universal Agent configuration PDSE is allocated to UNVCONF in the USLLSPRC and USLRMPRC JCL procedures in the SUNVSAMP library. The only other changes to USLLSPRC and USLRMPRC is the addition of a comment that the UNVDB and UNVSPOOL ddnames must be commented out to use zFS data sets.

USLIST and USLRM write messages UNV2264I and UNV2265I, which provide information on the Broker's database and spool, respectively. The messages also provide the file system type, data set name, and mount point.

JCL Procedure

The following figure illustrates the Universal Spool List for z/OS JCL procedure (USLLSPRC, located in the SUNVSAMP library) that is provided to simplify the execution JCL and future maintenance.

//USLLSPRC PROC UPARM=,               -- USLIST options
//             UNVPRE=#SHLQ.UNV,
//             CFGPRE=#PHLQ.UNV,
//             DBPRE=#PHLQ.UNV
//*
//PS1      EXEC PGM=USLIST,PARM='ENVAR(TZ=EST5EDT)/&UPARM'
//STEPLIB  DD  DISP=SHR,DSN=&UNVPRE..SUNVLOAD
//*
//UNVNLS   DD  DISP=SHR,DSN=&UNVPRE..SUNVNLS
//UNVCONF  DD  DISP=SHR,DSN=&CFGPRE..UNVCONF
//UNVDB    DD  DISP=SHR,DSN=&DBPRE..UNVDB
//UNVSPOOL DD  DISP=SHR,DSN=&DBPRE..UNVSPOOL
//UNVTRACE DD  SYSOUT=*
//CEEDUMP  DD  SYSOUT=*
//SYSUDUMP DD  SYSOUT=*
//SYSOUT   DD  SYSOUT=*
//SYSPRINT DD  SYSOUT=*

Note

If zFS data sets are being used instead of HFS data sets, the UNVDB and UNVSPOOL ddnames cannot be used to allocate those zFS data sets. They must be removed, along with the DBPRE procedure parameter.

DD Statements used in JCL Procedure

The following table describes the DD statements used in the Universal Spool List for z/OS JCL procedure, above.

ddname	Description
STEPLIB	Load library in which program USLIST program is located.
UNVNLS	Universal National Language Support library.
UNVCONF	Universal Agent configuration library.
UNVDB	Universal Broker Database data set (HFS only).
UNVSPOOL	Universal Spool Database data set (HFS only).
UNVTRACE	Application trace ddname.
SYSOUT	USLIST standard error ddname.
SYSPRINT	USLIST standard output ddname.

JCL

The following figure illustrates the Universal Spool List for z/OS JCL using the USLLSPRC JCL procedure, above (for HFS data sets).

HELP	Writes a description of the command options and their format.
LIST	Type of database from which to select record to write.
MESSAGE_LEVEL	Level of messages that will be written.
MOUNT_POINT	HFS directory in which the HFS databases allocated to ddnames UNVDB and UNVSPOOL are mounted.
VERSION	Writes the program version and copyright information.
