specify information for the following archive options:
- Archive Logs Used at DR Site
- Specify which archive logs are to be used at the DR site. Specify C to have IMS Recovery Expert copy your local archive logs and register them in the DR RECON data set. Specify Y if you want IMS Recovery Expert to use your copy of the primary archive logs. Specify 2 if you are using dual logging and you want IMS Recovery Expert to use your copy of the secondary archive logs at DR.
- Use RLDS datasets at DR Site
- Specify if you want IMS to use RLDS data sets for recovery at the DR site.
- Copy local archive logs
- If you specified to copy the local archive logs, then this field tells IMS Recovery Expert which logs to copy. Specify 1 to copy only the primary archive log. Specify 2 to copy only the secondary archive log. Specify B to copy both the primary and secondary archive logs. Specify C to create two copies from the primary log. IMS Recovery Expert will create recovery site primary and recovery site secondary logs from the local primary archive log.
- Number of archive copy tasks
- Specify how many tasks you want IMS Recovery Expert to assign to the archive log copy process. Specify a number between 1 and 32.
- Force an archive log switch
- This field allows you to force IMS Recovery Expert to issue a /SWI OLDS command prior to determining what archive logs exist. The current active online log is archived when this field is set to Y. For a data sharing group, each member's online logs will be switched and archived.
- Force checkpoint before archiving
- Specify Y to force a system checkpoint before archiving the logs. This will cause the IMS restart point to be included on the last archive log to be included for disaster recovery.
- Archive logs needed at DR site
- Specify the number of days and/or hours of archive logs that are needed at disaster recovery. This value is computed from the time the job is built at the local site. The recommended value for this field is (the longest duration between image copies at your site)*2. For example, if weekly image copies are the longest duration, then specify 14 in this field (7*2).
- Unit for copying archive logs
- Specify the tape or DASD unit device to be used to allocate data sets to be created when copying archive logs.
- Edit allocation parameters
- Specify Y in this field to edit to the archive log copy allocation parameter panel.
- Number of qualifiers to replace
- Specify how many qualifiers of the existing archive log data set name you want to replace with the disaster recovery archive log prefix.
- DR Archive Prefix 1 and 2
- Specify the archive log prefix 1 and 2 that the copied archive logs will have at the disaster recovery site. You can include &SSID in the prefix to have IMS Recovery Expert replace it with the IMS system name.
- Copy archives to DASD at DR site
- Indicate if you want IMS Recovery Expert to generate JCL to copy the archive logs from tape to DASD at the remote site as part of the remote site recovery process. Specify N if you do not want IMS Recovery Expert to generate JCL to copy any of the archive logs to DASD. Specify Y if you want IMS Recovery Expert to generate JCL to copy the archive logs from tape to DASD at the disaster recovery site. Specify U to edit the Update User Options for copying the archive logs to DASD panel.
- To configure more options, specify Y in
the Edit allocation parameters field, or specify U in
the Copy archives to DASD at the DR site field.
- If you specify Y in the Edit
allocation parameters field and press Enter, the Local
Archive copy allocation panel opens:
