SC19-4368-06
- Application operations redesign
- To improve performance and usability, the Application Operations menu and functionality have
been redesigned. Application profiles are now segmented into:
- Object profiles
- Utility profiles
- Job profiles
Coordination application profile functionality has not be altered. Users may also now run on-demand operations to build the following jobs without needing a pre-defined profile to work from:
- Recovery jobs
- Create Recovery Point jobs
- Quiet Time Analysis jobs
- Health Check jobs
- New options for controlling spawned job jobname and jobcard
- Using the new Update Spawned Job Options option, you can now override the default methods for jobname and jobcard generation.
- New recovery option for System Profile Recovery
- Using the new recovery type option INITONLY, you can set the System Recovery Profile so that the objects in the profile are initialized instead of recovered. This option is only valid for a DR System Recovery Profile.
SC19-4368-05
- ACB repository
- The new ACB repository is a VSAM KSDS that contains ACBs as loaded and/or updated from the active ACB library (ACBLIB). Use of the ACB repository improves the performance of IMS Recovery Expert functions that access the ACB libraries of large systems.
- New PARMLIB member to create unique default recovery options
- Using the new member BSY#SSID, you can now create unique, default recovery options for each IMS subsystem or IMS group.
- New parameter to control default recovery options
- Using the new BSY#PARM parameter IMS_GENJCL_DFLT_MBR, you can control the default recovery options
- New recovery options for System Recovery Profiles
- New recovery options for System Recovery Profiles allow you to specify the type of recovery that can be performed at the disaster recovery site. The three types of recovery that can be performed are PITR, LASTPITCA, and LASTIC.
- New parameters for recovery type options PITR, LASTPITCA, and LASTIC
- New parameters for the recovery type options PITR, LASTPITCA, and LASTIC include DR_LASTPITCA_AGE, DR_LASTPITCA_RANGE, DR_LASTIC_AGE, and DR_LASTIC_RANGE.
SC19-4368-04
- New parameter to control history information
- The new BSY#PARM parameter DR_HISTORY_RETENTION controls the creation and retention of history information associated with each time the Disaster Recovery preparation job is executed.
- New IDCAMS delete/define cards created upon job execution
- The Disaster Recovery Profile now enables the DR preparation job to create new IDCAMS delete/define cards each time the job executes. The cards can be placed in members in the DR PDS, or a new PDS can be created each time.
- New option to skip marking all DBDS as recovery needed
- The Disaster Recovery Profile can now skip the process to mark all DBDS as recovery needed when the DR preparation job executes. This process might not be required for your DR environment, and skipping it reduces execution time for the DR preparation job.
- New option to skip writing conditioned RECON to DR site
- You can now skip writing the conditioned RECON data sets to the DR PDS when you have other methods of sending the conditioned RECON to the DR site.
SC19-4368-03
- Run IBM IMS Database Recovery Facility/Extended Functions Health
- You can now choose to run the Health Check feature from the following
places:
- Run HCHECK against an application profile.
- Run HCHECK against a system level backup.
- In the Disaster Recovery Profile, you can set HCHECK to be run against the conditioned RECON data sets when the disaster recovery preparation job runs.
- Dynamic API enables IBM IMS Database Recovery Facility (DRF) and IBM IMS Database Recovery Facility/Extended Functions (DRF/XF) to use System Level Backups (SLBs)
- A new dynamic API enables a DRF or DRF/XF job to be aware of any SLB that you have taken which contains data that meets your criteria better than data in the RECON data sets. For example, if you are recovering a database to the current time, and the image copy in the RECON is older than the last SLB, then the API will allow DRF to use the SLB as the image copy, thus reducing the number of logs needed to complete the recovery.
- A new Recovery Sensor evaluates information in the RECON data sets to look for problems that can affect recovery
- The Recovery Sensor is a batch job that can either be scheduled by the Autonomics Director, or in any job scheduler, and is control card driven. To look for potential problems related to recovery, the Recovery Sensor obtains information from the RECON data sets that matches the criteria you specify. This information is stored in the IMS Tools Knowledge Base (ITKB). You can then create recovery policies to evaluate this information and notify you when problems are detected.
SC19-4368-02
- Checkpoint restart capability for local recovery
- Checkpoint restart capability is now available when performing local recoveries. To enable this
capability, you must:
- Add the new RECOV_CHKPT_RESTART = YES parameter to your BSY#PARM parameter member
- Tailor and execute the SBSYSAMP(BSYCHKPT) member to allocate the new checkpoint restart repository
- Edit your BSYV220 invocation CLIST and:
- add RBRCHKPT(dsn) on the PROC statement to specify the checkpoint data set
- add “ISPEXEC VPUT (RBRCHKPT) ASIS” after the PROC statement
For more information, see Managing application recovery checkpoint restart.
- Enhanced application recovery processing
- Enhancements have been made in application recovery processing
for both local and DR site application recovery, which allows more
flexibility in defining and executing the utilities required to complete
application recovery. With these changes, there are several areas
which must be addressed in order to perform application recovery.
- BSY#PARM member changes
The following BSY#PARM parameters are obsolete and must be removed from your BSY#PARM member:
- GENJCL_DRF_RECOV_MEM

The following BSY#PARM parameters have been renamed and must be changed in your BSY#PARM member:Old name New name GENJCL_USER_FPSI_MEM GENJCL_USER_FPIX_MEM GENJCL_USER_HALDB_MEM GENJCL_USER_HBIX_MEM GENJCL_USER_IX_MEM GENJCL_USER_FFIX_MEM GENJCL_USER_PR_MEM GENJCL_USER_IC_MEM IMS_POST_RECOV_UTIL IMS_IC_UTIL The following new parameters have been added to BSY#PARM and must be specified:USE_FFIX_FOR_HALDB_RBLD N -\* Specify "Y" to use the *\ -\* FFIX GENJCL member for *\ -\* processing HALDB PINDEX/ *\ -\* IDLS rebuild or "N" if *\ -\* that is not desired *\ INDEX_RBLD_WHEN_RECOV Y -\* Specify "Y" to have any *\ -\* index needing recovery to *\ -\* be rebuilt instead of *\ -\* recovered or "N" if this *\ -\* is not desired. *\ HALDB_RBLD_ON_RECOV_TO_CURRENT Y -\* Specify "Y" to have any *\ -\* HALDB ILDS/PINDEX rebuilt *\ -\* when the HALDB is *\ -\* recovered to current or *\ -\* "N" if this is not *\ -\* desired. *\ ACTION_ON_WARNING C -\* Specify the action to be *\ -\* taken if warnings occur *\ -\* during recovery, "W" to *\ -\* issue a WTOR to pause *\ -\* processing, "C" to *\ -\* continue, or "A" to *\ -\* abort. *\For more information on the BSY#PARM changes, see (Optional) Configuring the PARMLIB member.
- GENJCL member changes
- To provide more capability and flexibility for generating the jobs required to perform recovery, index rebuild, change accumulation, and image copy, the structure of the GENJCL members has changed. New members that support the IMS base utilities, IBM IMS Tools utilities, and user utilities have been supplied using the new format. You must modify your existing GENJCL skeletons that are used for application recovery when driven by IMS Recovery Expert. For more information, see Creating GENJCL skeletal members.
- Recovery options changes
- To provide more flexible processing options when performing the functions associated with
application recovery under IMS Recovery Expert, the recovery
options have been modified in the following places:
- System Recovery Profile recovery options
- Application Profile recovery options
- System Level Backup restore recovery options
Before you can perform any application recovery processing, you must edit and upgrade the recovery options for any of these areas you currently have set up. If you do not, then when you try to perform application recovery, you will receive an error that the recovery options need to be upgraded and jobs will not process until that is done.
SC19-4368-01
- Combined SLB
- You can now create a combined SLB for IMS and Db2. For more information, see Performing a Combined System Level Backup.
SC19-4368-00
- Storage group discovery
- When creating a backup profile and specifying the Source/Target Mapping, you can now specify a new option for SMS storage group discovery for source volumes. With this option, you specify the SMS storage group names which contain the IMS source volumes and all of the volumes in that storage group will be included in the backup. For more information, see Creating System Level Backup profiles for Combined SLB groups.
- Redesigned ISPF interface
- The ISPF interface has been redesigned for this version of the product.
