Instant JChem System Requirements

Hardware Requirements

Minimal requirements:

CPU

1.2 GHz dual-core or higher

RAM

2 GB or higher

Hard-drive space

1 GB

Instant JChem employs a sophisticated caching system so that it can handle large data sets without needing all the data to be in the memory. In general this works very well, but everything has its limits. You may need to increase the memory that IJC will have access to.

Additional memory for JChem Base database tables

  • Each million structures need additional 100 MB of memory

  • For 600 Markush structures, around 700 MB of additional memory is needed

  • For more detail, see memory usage documentation

For JChem Cartridge based solutions, minimum recommended memory should suffice. For server memory settings, see documentation here.

Software Requirements

Operating System

Instant JChem is tested on the following platforms:

  • Windows XP (32-bit)

  • Windows 7 (64-bit)

  • Windows 7 (32-bit) - only with Java 7

  • Windows 8 (64-bit)

  • Windows 10 (64bit)

  • GNU/Linux (32-bit, 64-bit)

  • Mac OS X (64-bit)

JChem Cartridge Compatibility

Instant JChem is tested with following JCC versions:

  • 5.7

  • 5.12

  • 6.3

  • Current (same version as last release)

Supported Databases

  • Derby

  • MySQL 5.5 and newer

  • Oracle 10g and newer

  • Composite

  • Microsoft SQL Server 2005 Express and newer

For more info, please refer to user guide.

Please note, that Instant JChem might work with older versions of the databases (such as Oracle 9i), but as we do not test those, full functionality is not guaranteed.

Known issues and limitations

  • MySQL tables created with COLLATION uft8_bin will not work. Current workaround is to use different collation. For example utf8_general_ci

  • Can not create IJC Schema on MySQL 5.7. Current workaround is to turn off NO_ZERO_DATE restriction in the MySQL server instance.

There are multiple ways to do that. E.g. find out your settings with:

SELECT @@GLOBAL.sql_mode;

and then apply new ones without NO_ZERO_DATE mode:

SET GLOBAL sql_mode = "<new-value-without-the-mode>";

Java

Supported major Java versions:

  • Java 6

  • Java 7

  • Java 8

Java 6 will be supported till mid 2015.
