You must configure each server within the iFileshare high availability group to use the same value for the ES_HA_VSAM environment variable.
ES_HA_VSAM=<status>;<APPLID1-info>[;<APPLID2-info>;<APPLID3-info>...]
Where:
- <status>
- The type of iFileshare configuration. Can be one of:
- N
- No iFileshare configuration enabled.
- S
- Single iFileshare mode enabled (that is, no High Availability options enabled).
- Y
- iFileshare (High Availablity) enabled.
- T
- iFileshare (High Availablity), with ISC tracing, enabled.
- <APPLID1-info>
- The details for the primary server in the iFileshare group. (Only applicable for status options Y and T.)
-
<region-name>,<host-name or protocol>,<ISC-port>,<mfds-port>
- Where:
- <region-name>
- Name of the region.
- <host-name or protocol>
- The host-name or the protocol of the region.
- If the protocol is TCP/IP, specify the host-name; that is, an IP address, localhost, or a server name (e.g. nwb-svr1). If the protocol is shared memory (Windows only), specify
ccism.
- <ISC-port>
- The port on which to host the dynamically generated ISC listener for the region; this port must be free.
- If ISC links have been manually configured, this entry is optional; omit the entry by either terminating the node configuration with a semicolon, or by omitting the text between commas. This option must be omitted if you are using shared memory.
- <mfds-port>
- The port on which MFDS is running for the region; this defaults to 86.
- If ISC links have been manually configured and MFDS is running on the default port (86), this entry is optional; omit the entry by either terminating the node configuration with a semicolon, or by omitting the text between commas. If MFDS is not hosted on the default port, you should always specify it, even if you have manually configured the ISC links.
-
- <APPLIDx-info>
- The details for a standby server(s) in the iFileshare high availability group. (Only applicable for status options Y and T.)
Important: The order in which you specify the standby servers determines the order that they are promoted to primary server status in the event of an automatic failover.
-
<region-name>,<host-name>,<ISC-port>,<mfds-port>
- Where:
- <region-name>
- Name of the region.
- <host-name>
- The host-name for the region.
- <ISC-port>
- As before.
- <mfds-port>
- As before.
Example:
The following variable value, which must be the same on each server specified within the group, creates an iFileshare group of one primary server: (Prim-1) and two standby servers (Stand-1 and Stand-2)
