ERROR: Could not open acquire_lock.status.

While performing few “emgr_update”operations, sometimes we get “Could not open acquire_lock.status.” error.

For example performing dimension upgrade or performing set_template and other for Endeca Experience Manager.

emgr_update --host localhost:172.20.187.149 --action set_templates --prefix MyDemo --dir /opt/endeca/apps/MyDemo/config/cartridge_templates -app_name MyDemo

In the above example, we miss to add port entry, adding correct port will fix the above issue.

C:\Endeca\PlatformServices\11.1.0\bin>emgr_update.bat --host localhost:8888 --app_name <appname> --prefix <appprefix> --action set_post_forge_dims --post_forge_file C:\Endeca\Apps\<appname>\<appname>.dimensions.xml

ERROR: Could not open acquire_lock.status.

In the above example and many other similar, we have to confirm that used “HOST” and “PORT” are correct. As if any of the entries are wrong we will get “Could not open acquir_lock.status.”
