LC190 liveCache Installation Step:
The /etc/cmcluster/<LCSID>/sap.config configuration file of a
liveCache package is similar to the configuration file of Netweaver
Instance packages.
The following standard parameters in sap.config have to be set for a
liveCache package:
LCRELOC=<reloclc_s>
TRANSRELOC=<relocsapnfs_s>
CLEANUP_POLICY= [ strict | normal | lazy ]
The strict option can be set in order to guarantee the liveCache package
gets all resources required on the adoptive node. Remember that this
option can crash a system running on the adoptive node.
• The following liveCache specific parameters in sap.config have to
be set:
LCSTARTMODE specifies the mode of the liveCache database up to which it
should be started automatically. Possible values for version 7.4 of
liveCache are:
OFFLINE: only vserver will be started
ADMIN: liveCache started in cold mode
SLOW: liveCache started in cold -slow mode
ONLINE: liveCache started in warm mode
In liveCache version 7.5 some of these values have changed: (<from> ->
<to>)
COLD -> ADMIN
WARM -> ONLINE
It is recommended to use the new values for liveCache version 7.5. For
compatibility reasons the original values will still work though.
After failover, liveCache will only be recovered to the state referenced in
LCSTARTMODE.
The behavior of the liveCache service monitoring script is independent
from the setting of LCSTARTMODE. The monitoring script will always
monitor the vserver process. It will start to monitor if liveCache is in
WARM state, as soon as it reaches WARM state for the first time.
