All,
For WMQ v7, IBM now says that using the MQ Java CLNTCONN constants HEADER_COMPRESSION_PROPERTY and MESSAGE_COMPRESSION_PROPERTY are deprecated. Also, the constants (MQCOMPRESS_NONE, MQCOMPRESS_RLE, MQCOMPRESS_ZLIBFAST & MQCOMPRESS_ZLIBHIGH) that go with those properties are deprecated.
i.e.
| Code: |
Hashtable mqht = new Hashtable();
mqht.put(MQC.CHANNEL_PROPERTY, "channelName");
mqht.put(MQC.HOST_NAME_PROPERTY, "hostname");
mqht.put(MQC.PORT_PROPERTY, new Integer("port#"));
mqht.put(MQC.HEADER_COMPRESSION_PROPERTY, MQC.MQCOMPRESS_SYSTEM);
mqht.put(MQC.MESSAGE_COMPRESSION_PROPERTY, MQC.MQCOMPRESS_ZLIBFAST);
_qMgr = new MQQueueManager("qMgrName", mqht); |
The manual does not list what I should be using. Does anyone know what MQ Java constants are the replacements for the above listed constants?
Regards,

I would just switch to using a CCDT entry?
Otherwise, MQC.* is replaced by the appropriate CMQC constant class to match the C library structures better. |

MQFM supports both explicit values and the use of a CCDT.

Never thought to compare WMQ v7.0 and WMQ v7.1 documentation. Someone at IBM fat fingered it because in WMQ v7.1 the documentation does not list the HEADER_COMPRESSION_PROPERTY and MESSAGE_COMPRESSION_PROPERTY constants as deprecated. It only shows that MQCOMPRESS_NONE, MQCOMPRESS_RLE, MQCOMPRESS_ZLIBFAST and MQCOMPRESS_ZLIBHIGH are deprecated.
i.e.
| Code: |
Hashtable mqht = new Hashtable();
mqht.put(MQC.CHANNEL_PROPERTY, "channelName");
mqht.put(MQC.HOST_NAME_PROPERTY, "hostname");
mqht.put(MQC.PORT_PROPERTY, new Integer("port#"));
mqht.put(MQC.HEADER_COMPRESSION_PROPERTY, CMQC.MQCOMPRESS_SYSTEM);
mqht.put(MQC.MESSAGE_COMPRESSION_PROPERTY, CMQC.MQCOMPRESS_ZLIBFAST);
_qMgr = new MQQueueManager("qMgrName", mqht); |
Weird. But it explains why I couldn't find them anywhere else.
