不修改源代码的方案
系统内置的MaxJobId=999999，支持的MaxJobIdLow=999999，MaxJobIdHigh=9999999。即允许的jobId最大值属于集合[999999,9999999]。可通过配置lsb.params文件中的MAX_JOBID值来设置MaxJobId。通过bparams -l 查看。
修改配置文件
MAX_JOBID=9999999
重新读取配置
badmin mbdrestart
查看配置
bparams -l |grep MAX_JOBID
修改源代码的方案
主要相关代码分为3部分
代码片段：
1、定义片段 lsbatch\lsbatch.h
#define DEF_MAX_JOBID 999999
#define MAX_JOBID_LOW 999999
#define MAX_JOBID_HIGH 9999999
2、获取nextJobId片段 lsbatch\daemons\mbd.job.c
nextJobId = (nextJobId < maxJobId)? nextJobId : 1;
while ((getJobData (nextJobId) != NULL
&& i <= maxJobId)) {
nextJobId++;
i++;
if (nextJobId >= maxJobId)
nextJobId = 1;
}
3、读取配置文件的maxJobId lsbatch\lib\lsb.conf.c
else if (i == 31) {
int value = 0;
value = my_atoi(keylist[i].val, INFINIT_INT, 0);
if ( (value < MAX_JOBID_LOW)
|| (value > MAX_JOBID_HIGH) )
{
/*catgets 5062*/
ls_syslog( LOG_ERR,
I18N(5062, "%s: File%s in section Parameters ending at line %d: maxJobId value %s not in [%d, %d], use default value %d;"),
__func__,
fname,
*lineNum,
keylist[i].key,
MAX_JOBID_LOW,
MAX_JOBID_HIGH,
DEF_MAX_JOBID);
• lsberrno = LSBE_CONF_WARNING;
• pConf->param->maxJobId = DEF_MAX_JOBID;
}
else
{
• pConf->param->maxJobId = value;
}
只要修改片段1中的DEF_MAX_JOBID和MAX_JOBID_HIGH即可，最大支持2^31-1=2147483647。
修改完后，重新编译打包
./configure && make && make install
替换相对应的程序
cp -f openlava1/lib/liblsbatch.* openlava4.0/lib/
cp openlava1/sbin/mbatchd openlava4.0/sbin/
cp openlava1/sbin/sbatchd openlava4.0/sbin/
#还有一些程序可能有影响，例如lib daemons cmd bhist man1 man5 man8
