User data sets and libraries

Table 2. User data sets and libraries
File name Purpose
hlq.AUDITDB The Audit database. This file contains a list of files that were encountered but were not part of an application defined in hlq.USERMAC(APPTABLE). It can be used to audit whether production files are being used in non-production jobs.
hlq.AUDITL2 Contains discarded records filtered out of the AUDITDB file during the HISMAINT process.
hlq.AUDTDS An intermediate file used by Real-Time Analysis to store audit data (that is, non-production files). This file is flushed every 10 minutes to the AUDITDB file.
hlq.BKUPJCL A PDS containing the ABARS Verify JCL if ABARS is a selected backup method. Otherwise, this file is not used.
hlq.BKUPJCL.BKUPMETH Generated Backup JCL for a particular backup method (see hlq.BKUPMETH). BKUPMETH refers to the utility used to backup files, for example: hlq.BKUPJCL.DSS.
hlq.BKUPMETH A small data set containing a list of all supported backup methods and which of those are in use in this installation. This file also contains the name of the backup and restore data sets for the backup methods.
hlq.CNTL JCL to run IZBR.
hlq.CRITICAL The Critical File List. It is used for reporting only in the non-SAS releases.
hlq.DB2BRNCR Critical Db2® files.
hlq.DB2BRNLG Db2 Image Copy files.
hlq.DMS This file is obsolete.
hlq.HISTORY IZBR History database. The keyed history feature database is built from this file.
hlq.HISTRYL2 Contains discarded records filtered out of the HISTORY file during the HISMAINT process.
hlq.HSMACT Sequential data set used to track ABAR log data sets read by program ABARBKUP.
hlq.IMS.RECONLST An unloading of the IMS RECON file.
hlq.IMS.RECONOUT Processed RECONLST to isolate backup information for IMS.
hlq.IMS.RESPRT List of IMS RESLIB files.
hlq.INVMAINT.NEGFILE List of data sets deleted during the INVMAINT process.
hlq.INVENTRY The IZBR Inventory database. This file contains data about all files defined to production applications.
hlq.KEYDHIST History data set keyed by data set name.
hlq.KEYJHIST History data set keyed by job name.
hlq.MODEL Model DSCB for IZBR Analysis database and recovery files.
hlq.ODTCKPT A checkpoint file for the Real-Time Analysis process. This file and the RTACKPT file provide backup of the data in memory for the Real-Time Analysis process in case something causes it to abnormally terminate.
hlq.PRODDS SMF data relating to production data set from the last collection.
hlq.REPORTS IZBR reports library.
hlq.RESTJCL A PDS containing IZBR-generated restore JCL.
hlq.RESTJCL.BKUPMETH A PDS containing JCL/control statements to restore critical files successfully backed up in the database. BKUPMETH refers to the utility used to back up files. For example, hlq.RESTJCL.DSS. See hlq. BKUPMETH in this table.
hlq.RESTTBL This table tracks files that have been restored and is necessary to be at a disaster recovery site. If, for some reason, any of the RESTJCL.BKUPMETH libraries should be corrupted at the disaster recovery site, or it is necessary to restart the restore process, running the RESTJCL job taking this file as an input creates the JCL to restore the outstanding files.
hlq.RTACKPT A checkpoint file for the Real-Time Analysis engine. This file and the ODTCKPT file provide backup of the data in memory for the Real-Time Analysis process in case something causes it to abnormally terminate.
hlq.RTCMDQ This small data set is used to pass commands to the Real-Time Analysis function.
hlq.SMFEXT.ssss.SMF$yy.Tjjjhhmm SMF extract file created by the SMF Extractor. ssss refers to the system name on which the data was created. yy refers to the year the file was created. jjjhhmm refers to the Julian date and time when the file was created (24 hrs).
hlq.SNAP.CRITDSNS IZBR InstaSnap critical data set information used to identify critical data sets to be backed up using FlashCopy before a job step starts.
hlq.SNAP.JOBNAMES IZBR InstaSnap eligible job names information used to identify jobs that are eligible for InstaSnap backup processing.
hlq.SNAP.INSTEXCP IZBR InstaSnap exception log information used to identify data set copies that generated non-zero return codes.
hlq.TAPEJCL A PDS containing IZBR-generated backup JCL (tape). This file is empty until TAPEJCL has executed.
hlq.USERMAC IZBR user code library. User exits and IZBR customizations are stored here.
hlq.VTOCDUMP Output from the VTOCDUMP program.
