J.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 Environment

Stop ETERNUS SF Manager.
- For non-cluster operation
  1. Open the Services screen.
    For Windows Server 2012 or later, click Control Panel > System and Security > Administrative Tools > Services.
    For a Windows environment other than listed above, click Control Panel > Administrative Tools > Services.
  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 a value found by adding 2 GB to the memory size estimated in "J.1 Estimating Memory Size When Using Large Numbers of Volumes".
EXAMPLE
When setting a memory size to 4 GB
```
-Xmx=4096m
```
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.
