Automatic memory allocation for the command-line tools
At setup, the PingDirectory server automatically allocates memory to each command-line utility based on the maximum Java Virtual Machine (JVM) heap size.
The server sets each command-line utility in the config/java.properties
file with -Xmx/Xms
values, depending on the expected memory needs of the tools.
Because some tools can be invoked as a server task while the server is online, there are two definitions of the tool in the config/java.properties
file:
.Online
-
Typically requires minimal memory because the task is performed within the PingDirectory server’s JVM.
.Offline
-
Can require the same amount of memory needed by the server. Examples include
import-ldif.offline
andrebuild-index.offline
.
With large databases, some tools, such as ldap-diff
and verify-index
, might need more than the minimal memory. The following table lists the tools that are expected to have more than the minimal memory needs along with the rules for defining the default heap size.
Command-Line Tools | Allocated JVM Memory |
---|---|
start-server, import-ldif (offline), rebuild-index (offline) |
MaxHeapSize |
backup (offline), dbtest export-ldif (offline), ldap-diff, restore (offline), scramble-ldif, summarize-access-log, verify-index |
