I.2 Memory Settings to ETERNUS SF Manager When Using Large Numbers of Volumes

When using large numbers of volumes, it is required to set a memory size that ETERNUS SF Manager Tomcat Daemon/Service uses. Take the following steps for settings:

For Windows Environments

Stop ETERNUS SF Manager.
- For non-cluster operation
  1. Click Control Panel > System and Security > Administrative Tools > Services to open the Services screen.
  2. Select "ETERNUS SF Manager Tomcat Service" to click Stop.
- For cluster operation
  Use Failover Cluster Manager to stop ETERNUS SF Manager.
Execute the following command. In the case of cluster operation, execute the command on both primary and secondary nodes.
```
> $INS_DIR\Common\sys\tomcat\bin\esfservice.bat remove
```
$INS_DIR is "Program Directory" specified at the ETERNUS SF Manager installation.
Edit the following file. In the case of cluster operation, edit the file on both primary and secondary nodes.
```
$INS_DIR\Common\sys\tomcat\conf\esfsetenv.conf
```
Add the following line to the above file. If there is already an entry in "-Xmx", edit memorySize.
```
-Xmx=memorySize
```
memorySize : Specify a memory size to be used in terms of megabytes. Put "m" at the end of the memory size specified in figures.
Specify the total of the following values as the memory size: the memory size described in "2.2.5.2 Required Memory for Operation" and the estimated memory size described in "I.1 Estimating Memory Size When Using Large Numbers of Volumes".
EXAMPLE
When setting a memory size to 8 GB
```
-Xmx=8192m
```
Execute the following command. In the case of cluster operation, execute the command on both primary and secondary nodes.
```
> $INS_DIR\Common\sys\tomcat\bin\esfservice.bat install
```
Start ETERNUS SF Manager.
- For non-cluster operation
