OFFSITE
The OFFSITE system initialization parameter specifies whether CICS® is to restart in off-site recovery mode; that is, a restart is taking place at a remote site.
Defining OFFSITE
You can define the OFFSITE system initialization parameter in the following ways:
- In the PARM parameter of the EXEC PGM=DFHSIP statement.
- In the SYSIN data set of the CICS startup job stream.
- Through the system console.
Values for OFFSITE
Valid values for the OFFSITE system initialization parameter are as follows:
- OFFSITE={NO|YES}
- For a successful off-site restart, the log records of the failed CICS region must be available at the remote site. CICS does not provide a facility for shipping log records to a remote backup
site, but you can use a suitable vendor product to perform this function. See the relevant product
documentation for other procedures you need to follow for a remote site restart.
See Administering restart and recovery for more information about remote site recovery.
- NO
- NO is the default value for OFFSITE. CICS will not perform the special restart processing required for remote site recovery.
- YES
- CICS will perform an off-site restart at a remote site
following a disaster at the primary site. CICS performs this
special processing for an off-site restart, because some information (for example, a VSAM lock
structure) is not available at the remote site.
CICS performs an emergency restart, even if the global catalog indicates that CICS can do a warm start. OFFSITE=YES is valid with START=AUTO only, and CICS initialization is terminated if you specify START=COLD or INITIAL.
Restriction: You can specify the OFFSITE system initialization parameter in PARM, SYSIN, or CONSOLE
only.
